Full ChangeLog for 2024-02-22

• Improvements:
  • IP Adapter major refactor
    • support for multiple input images per each ip adapter
    • support for multiple concurrent ip adapters
      note: you cannot mix & match ip adapters that use different CLiP models, for example Base and Base ViT-G
    • add adapter start/end to settings, thanks @AI-Casanova
      having adapter start late can help with better control over composition and prompt adherence
      having adapter end early can help with overal quality and performance
    • unified interface in txt2img, img2img and control
    • enhanced xyz grid support
  • FaceID now also works with multiple input images!
  • Differential diffusion
    img2img generation where you control strength of each pixel or image area
    can be used with manually created masks or with auto-generated depth-maps uses general denoising strength value
    simply enable from img2img -> scripts -> differential diffusion
    note: supports sd15 and sdxl models
  • Regional prompting as a built-in solution
    usage is same as original implementation from @hako-mikan
    click on title to open docs and see examples of full syntax on how to use it
    simply enable from scripts -> regional prompting
    note: supports sd15 models only
  • DeepCache model acceleration
    it can produce massive speedups (2x-5x) with no overhead, but with some loss of quality
    settings -> compute -> model compile -> deep-cache and settings -> compute -> model compile -> cache interval
  • ZLUDA experimental support, thanks @lshqqytiger
    • ZLUDA is CUDA wrapper that can be used for GPUs without native support
    • best use case is AMD GPUs on Windows, see wiki for details
  • Outpaint control outpaint now uses new alghorithm: noised-edge-extend
    new method allows for much larger outpaint areas in a single pass, even outpaint 512->1024 works well
    note that denoise strength should be increased for larger the outpaint areas, for example outpainting 512->1024 works well with denoise 0.75
    outpaint can run in img2img mode (default) and inpaint mode where original image is masked (if inpaint masked only is selected)
  • Clip-skip reworked completely, thanks @AI-Casanova & @Disty0
    now clip-skip range is 0-12 where previously lowest value was 1 (default is still 1)
    values can also be decimal to interpolate between different layers, for example clip-skip: 1.5, thanks @AI-Casanova
  • CFG End new param to control image generation guidance, thanks @AI-Casanova
    sometimes you want strong control over composition, but you want it to stop at some point
    for example, when used with ip-adapters or controlnet, high cfg scale can overpower the guided image
  • Control
    • when performing inpainting, you can specify processing resolution using size->mask
    • units now have extra option to re-use current preview image as processor input
  • Cross-attention refactored cross-attention methods, thanks @Disty0
    • for backend:original, its unchanged: SDP, xFormers, Doggettxs, InvokeAI, Sub-quadratic, Split attention
    • for backend:diffuers, list is now: SDP, xFormers, Batch matrix-matrix, Split attention, Dynamic Attention BMM, Dynamic Attention SDP
      note: you may need to update your settings! Attention Slicing is renamed to Split attention
    • for ROCm, updated default cross-attention to Scaled Dot Product
  • Dynamic Attention Slicing, thanks @Disty0
    • dynamically slices attention queries in order to keep them under the slice rate
      slicing gets only triggered if the query size is larger than the slice rate to gain performance
      Dynamic Attention Slicing BMM uses Batch matrix-matrix
      Dynamic Attention Slicing SDP uses Scaled Dot Product
    • settings -> compute settings -> attention -> dynamic attention slicing
  • ONNX:
    • allow specify onnx default provider and cpu fallback
      settings -> diffusers
    • allow manual install of specific onnx flavor
      settings -> onnx

Update for 2024-02-07

Another big release just hit the shelves!

Highlights 2024-02-07

• A lot more functionality in the Control module:
  • Inpaint and outpaint support, flexible resizing options, optional hires
  • Built-in support for many new processors and models, all auto-downloaded on first use
  • Full support for scripts and extensions
• Complete Face module
  implements all variations of FaceID, FaceSwap and latest PhotoMaker and InstantID
• Much enhanced IPAdapter modules
• Brand new Intelligent masking, manual or automatic
  Using ML models (LAMA object removal, REMBG background removal, SAM segmentation, etc.) and with live previews
  With granular blur, erode and dilate controls
• New models and pipelines:
  Segmind SegMoE, Mixture Tiling, InstaFlow, SAG, BlipDiffusion
• Massive work integrating latest advances with OpenVINO, IPEX and ONNX Olive
• Full control over brightness, sharpness and color shifts and color grading during generate process directly in latent space
• Documentation! This was a big one, with a lot of new content and updates in the WiKi

Plus welcome additions to UI performance, usability and accessibility and flexibility of deployment as well as API improvements
And it also includes fixes for all reported issues so far

As of this release, default backend is set to diffusers as its more feature rich than original and supports many additional models (original backend does remain as fully supported)

Also, previous versions of SD.Next were tuned for balance between performance and resource usage.
With this release, focus is more on performance.
See Benchmark notes for details, but as a highlight, we are now hitting ~110-150 it/s on a standard nVidia RTX4090 in optimal scenarios!

Full ChangeLog 2024-02-07

• Heavily updated Wiki
• Control:
  • new docs:
    • Control overview
    • Control guide, thanks @Aptronymist
  • add inpaint support
    applies to both img2img and controlnet workflows
  • add outpaint support
    applies to both img2img and controlnet workflows
    note: increase denoising strength since outpainted area is blank by default
  • new mask module
    • granular blur (gaussian), erode (reduce or remove noise) and dilate (pad or expand)
    • optional live preview
    • optional auto-segmentation using ml models
      auto-segmentation can be done using segment-anything models or rembg models
      note: auto segmentation will automatically expand user-masked area to segments that include current user mask
    • optional auto-mask
      if you dont provide mask or mask is empty, you can instead use auto-mask to automatically generate mask
      this is especially useful if you want to use advanced masking on batch or video inputs and dont want to manually mask each image
      note: such auto-created mask is also subject to all other selected settings such as auto-segmentation, blur, erode and dilate
    • optional object removal using LaMA model
      remove selected objects from images with a single click
      works best when combined with auto-segmentation to remove smaller objects
    • masking can be combined with control processors in which case mask is applied before processor
    • unmasked part of can is optionally applied to final image as overlay, see settings mask_apply_overlay
  • support for many additional controlnet models
    now built-in models include 30+ SD15 models and 15+ SDXL models
  • allow resize both before and after generate operation
    this allows for workflows such as: image -> upscale or downscale -> generate -> upscale or downscale -> output
    providing more flexibility and than standard hires workflow
    note: resizing before generate can be done using standard upscalers or latent
  • implicit hires
    since hires is only used for txt2img, control reuses existing resize functionality any image size is used as txt2img target size
    but if resize scale is also set its used to additionally upscale image after initial txt2img and for hires pass
  • add support for scripts and extensions
    you can now combine control workflow with your favorite script or extension
    note extensions that are hard-coded for txt2img or img2img tabs may not work until they are updated
  • add depth-anything depth map processor and trained controlnet
  • add marigold depth map processor
    this is state-of-the-art depth estimation model, but its quite heavy on resources

  • FaceID
    • faceid guides image generation given the input image
    • full implementation for SD15 and SD-XL, to use simply select from Scripts
      Base (93MB) uses InsightFace to generate face embeds and OpenCLIP-ViT-H-14 (2.5GB) as image encoder
      Plus (150MB) uses InsightFace to generate face embeds and CLIP-ViT-H-14-laion2B (3.8GB) as image encoder
      SDXL (1022MB) uses InsightFace to generate face embeds and OpenCLIP-ViT-bigG-14 (3.7GB) as image encoder
  • FaceSwap
    • face swap performs face swapping at the end of generation
    • based on InsightFace in-swapper
  • PhotoMaker
    • for SD-XL only
    • new model from TenencentARC using similar concept as IPAdapter, but with different implementation and
      allowing full concept swaps between input images and generated images using trigger words

  • InstantID
    • for SD-XL only
    • based on custom trained ip-adapter and controlnet combined concepts
    • note: controlnet appears to be heavily watermarked

  • initial support for reference models
    download&load via network -> models -> reference -> SegMoE SD 4x2 (3.7GB), SegMoE XL 2x1 (10GB), SegMoE XL 4x2
  • note: since segmoe is basically sequential mix of unets from multiple models, it can get large
    SD 4x2 is ~4GB, XL 2x1 is ~10GB and XL 4x2 is 18GB
  • supports lora, thanks @AI-Casanova

Update for 2023-11-06

Another pretty big release, this time with focus on new models (3 new model types), new backends and optimizations Plus quite a few fixes

Also, Wiki has been updated with new content, so check it out!
Some highlights: OpenVINO, IntelArc, DirectML, ONNX/Olive

• Diffusers
  • since now SD.Next supports 12 different model types, weve added reference model for each type in
    Extra networks -> Reference for easier select & auto-download
    Models can still be downloaded manually, this is just a convenience feature & a showcase for supported models
  • new model type: Segmind SSD-1B
    its a distilled model trained at 1024px, this time 50% smaller and faster version of SD-XL!
    (and quality does not suffer, its just more optimized)
    test shows batch-size:4 with 1k images at full quality used less than 6.5GB of VRAM
    and for further optimization, you can use built-in TAESD decoder,
    which results in batch-size:16 with 1k images using 7.9GB of VRAM select from extra networks -> reference or download using built-in Huggingface downloader: segmind/SSD-1B
  • new model type: Pixart-α XL 2
    in medium/512px and large/1024px variations
    comparable in quality to SD 1.5 and SD-XL, but with better text encoder and highly optimized training pipeline
    so finetunes can be done in as little as 10% compared to SD/SD-XL (note that due to much larger text encoder, it is a large model)
    select from extra networks -> reference or download using built-in Huggingface downloader: PixArt-alpha/PixArt-XL-2-1024-MS
  • new model type: LCM: Latent Consistency Models
    trained at 512px, but with near-instant generate in a as little as 3 steps!
    combined with OpenVINO, generate on CPU takes less than 5-10 seconds: https://www.youtube.com/watch?v=b90ESUTLsRo
    and absolute beast when combined with HyperTile and TAESD decoder resulting in 28 FPS
    (on RTX4090 for batch 16x16 at 512px)
    note: set sampler to Default before loading model as LCM comes with its own LCMScheduler sampler
    select from extra networks -> reference or download using built-in Huggingface downloader: SimianLuo/LCM_Dreamshaper_v7
  • support for Custom pipelines, thanks @disty0
    download using built-in Huggingface downloader
    think of them as plugins for diffusers not unlike original extensions that modify behavior of ldm backend

Update for 2023-10-17

This is a major release, with many changes and new functionality...

Changelog is massive, but do read through or youll be missing on some very cool new functionality
or even free speedups and quality improvements (regardless of which workflows youre using)!

Note that for this release its recommended to perform a clean install (e.g. fresh git clone)
Upgrades are still possible and supported, but clean install is recommended for best experience

• UI
  • added change log to UI
    see System -> Changelog
  • converted submenus from checkboxes to accordion elements
    any ui state including state of open/closed menus can be saved as default!
    see System -> User interface -> Set menu states
  • new built-in theme invoked
    thanks @BinaryQuantumSoul
  • add compact view option in settings -> user interface
  • small visual indicator bottom right of page showing internal server job state
• Extra networks:
  • Details
    • new details interface to view and save data about extra networks
      main ui now has a single button on each en to trigger details view
    • details view includes model/lora metadata parser!
    • details view includes civitai model metadata!
  • Metadata:
    • you can scan civitai
      for missing metadata and previews directly from extra networks
      simply click on button in top-right corner of extra networks page
  • Styles
    • save/apply icons moved to extra networks
    • can be edited in details view
    • support for single or multiple styles per json
    • support for embedded previews
    • large database of art styles included by default
      can be disabled in settings -> extra networks -> show built-in
    • styles can also be used in a prompt directly: <style:style_name>
      if style if an exact match, it will be used
      otherwise it will rotate between styles that match the start of the name
      that way you can use different styles as wildcards when processing batches
    • styles can have extra fields, not just prompt and negative prompt
      for example: "Extra: sampler: Euler a, width: 480, height: 640, steps: 30, cfg scale: 10, clip skip: 2"
  • VAE
    • VAEs are now also listed as part of extra networks
    • Image preview methods have been redesigned: simple, approximate, taesd, full
      please set desired preview method in settings
    • both original and diffusers backend now support "full quality" setting
      if you desired model or platform does not support FP16 and/or you have a low-end hardware and cannot use FP32
      you can disable "full quality" in advanced params and it will likely reduce decode errors (infamous black images)
  • LoRA
    • LoRAs are now automatically filtered based on compatibility with currently loaded model
      note that if lora type cannot be auto-determined, it will be left in the list
  • Refiner
    • you can load model from extra networks as base model or as refiner
      simply select button in top-right of models page
  • General
    • faster search, ability to show/hide/sort networks
    • refactored subfolder handling
      note: this will trigger model hash recalculation on first model use
• Diffusers:
  • better pipeline auto-detect when loading from safetensors
  • SDXL Inpaint
    • although any model can be used for inpainiting, there is a case to be made for
      dedicated inpainting models as they are tuned to inpaint and not generate
    • model can be used as base model for img2img or refiner model for txt2img
      To download go to Models -> Huggingface:
      • diffusers/stable-diffusion-xl-1.0-inpainting-0.1 (6.7GB)
  • SDXL Instruct-Pix2Pix
    • model can be used as base model for img2img or refiner model for txt2img
      this model is massive and requires a lot of resources!
      to download go to Models -> Huggingface:
      • diffusers/sdxl-instructpix2pix-768 (11.9GB)
  • SD Latent Upscale
    • you can use SD Latent Upscale models as refiner models
      this is a bit experimental, but it works quite well!
      to download go to Models -> Huggingface:
      • stabilityai/sd-x2-latent-upscaler (2.2GB)
      • stabilityai/stable-diffusion-x4-upscaler (1.7GB)
  • better Prompt attention
    should better handle more complex prompts
    for sdxl, choose which part of prompt goes to second text encoder - just add TE2: separator in the prompt
    for hires and refiner, second pass prompt is used if present, otherwise primary prompt is used
    new option in settings -> diffusers -> sdxl pooled embeds
    thanks @AI-Casanova
  • better Hires support for SD and SDXL
  • better TI embeddings support for SD and SDXL
    faster loading, wider compatibility and support for embeddings with multiple vectors
    information about used embedding is now also added to image metadata
    thanks @AI-Casanova
  • better Lora handling
    thanks @AI-Casanova
  • better SDXL preview quality (approx method)
    thanks @BlueAmulet
  • new setting: settings -> diffusers -> force inpaint
    as some models behave better when in inpaint mode even for normal img2img tasks
• Upscalers:
  • pretty much a rewrite and tons of new upscalers - built-in list is now at 42
  • fix long outstanding memory leak in legacy code, amazing this went undetected for so long
  • more high quality upscalers available by default
    SwinIR (2), ESRGAN (12), RealESRGAN (6), SCUNet (2)
  • if that is not enough, there is new chaiNNer integration:
    adds 15 more upscalers from different families out-of-the-box:
    HAT (6), RealHAT (2), DAT (1), RRDBNet (1), SPSRNet (1), SRFormer (2), SwiftSR (2)
    and yes, you can download and add your own, just place them in models/chaiNNer
  • two additional latent upscalers based on SD upscale models when using Diffusers backend
    SD Upscale 2x, SD Upscale 4x*
    note: Recommended usage for SD Upscale is by using second pass instead of upscaler
    as it allows for tuning of prompt, seed, sampler settings which are used to guide upscaler
  • upscalers are available in xyz grid
  • simplified settings->postprocessing->upscalers
    e.g. all upsamplers share same settings for tiling
  • allow upscale-only as part of txt2img and img2img workflows
    simply set denoising strength to 0 so hires does not get triggered
  • unified init/download/execute/progress code
  • easier installation
• Samplers:
  • moved ui options to submenu
  • default list for new installs is now all samplers, list can be modified in settings
  • simplified samplers configuration in settings
    plus added few new ones like sigma min/max which can highly impact sampler behavior
  • note that list of samplers is now different since keeping a flat-list of all possible
    combinations results in 50+ samplers which is not practical
    items such as algorithm (e.g. karras) is actually a sampler option, not a sampler itself
• CivitAI:
  • civitai model download is now multithreaded and resumable
    meaning that you can download multiple models in parallel
    as well as resume aborted/incomplete downloads
  • civitai integration in models -> civitai can now find most
    previews AND metadata for most models (checkpoints, loras, embeddings)
    metadata is now parsed and saved in [model].json
    typical hit rate is >95% for models, loras and embeddings
  • description from parsed model metadata is used as model description if there is no manual
    description file present in format of [model].txt
  • to enable search for models, make sure all models have set hash values
    Models -> Valida -> Calculate hashes
• LoRA
  • new unified LoRA handler for all LoRA types (lora, lyco, loha, lokr, locon, ia3, etc.)
    applies to both original and diffusers backend
    thanks @AI-Casanova for diffusers port
  • for backend:original, separate lyco handler has been removed
• Compute
  • CUDA:
    • default updated to torch 2.1.0 with cuda 12.1
    • testing moved to torch 2.2.0-dev/cu122
    • check out generate context menu -> show nvml for live gpu stats (memory, power, temp, clock, etc.)
  • Intel Arc/IPEX:
    • tons of optimizations, built-in binary wheels for Windows
      i have to say, intel arc/ipex is getting to be quite a player, especially with openvino
      thanks @Disty0 @Nuullll
  • AMD ROCm:
    • updated installer to support detect ROCm 5.4/5.5/5.6/5.7
    • support for torch-rocm-5.7
  • xFormers:
    • default updated to 0.0.23
    • note that latest xformers are still not compatible with cuda 12.1
      recommended to use torch 2.1.0 with cuda 11.8
      if you attempt to use xformers with cuda 12.1, it will force a full xformers rebuild on install
      which can take a very long time and may/may-not work
    • added cmd param --use-xformers to force usage of exformers
  • GC:
    • custom garbage collect threshold to reduce vram memory usage, thanks @Disty0
      see settings -> compute -> gc
• Inference
  • new section in settings
    • HyperTile: new!
      available for diffusers and original backends
      massive (up to 2x) speed-up your generations for free :)
      note: hypertile is not compatible with any extension that modifies processing parameters such as resolution
      thanks @tfernd
    • Free-U: new!
      available for diffusers and original backends
      improve generations quality at no cost (other than finding params that work for you)
      note: temporarily disabled for diffusers pending release of diffusers==0.22
      thanks @ljleb
    • Token Merging: not new, but updated
      available for diffusers and original backends
      speed-up your generations by merging redundant tokens
      speed up will depend on how aggressive you want to be with token merging
    • Batch mode
      new option settings -> inference -> batch mode
      when using img2img process batch, optionally process multiple images in batch in parallel
      thanks @Symbiomatrix
• NSFW Detection/Censor
  • install extension: NudeNet
    body part detection, image metadata, advanced censoring, etc...
    works for text, image and process workflows
    more in the extension notes
• Extensions
  • automatic discovery of new extensions on github
    no more waiting for them to appear in index!
  • new framework for extension validation
    extensions ui now shows actual status of extensions for reviewed extensions
    if you want to contribute/flag/update extension status, reach out on github or discord
  • better overall compatibility with A1111 extensions (up to a point)
  • MultiDiffusion
    has been removed from list of built-in extensions
    you can still install it manually if desired
  • [LyCORIS]https://github.com/KohakuBlueleaf/a1111-sd-webui-lycoris
    has been removed from list of built-in extensions
    it is considered obsolete given that all functionality is now built-in
• General
  • Startup
    • all main CLI parameters can now be set as environment variable as well
      for example --data-dir <path> can be specified as SD_DATADIR=<path> before starting SD.Next
  • XYZ Grid
    • more flexibility to use selection or strings
  • Logging
    • get browser session info in server log
    • allow custom log file destination
      see webui --log
    • when running with --debug flag, log is force-rotated
      so each sdnext.log.* represents exactly one server run
    • internal server job state tracking
  • Launcher
    • new webui.ps1 powershell launcher for windows (old webui.bat is still valid)
      thanks @em411
  • API
    • add end-to-end example how to use API: cli/simple-txt2img.js
      covers txt2img, upscale, hires, refiner
  • train.py
    • wrapper script around built-in kohyas lora training script
      see cli/train.py --help
      new support for sd and sdxl, thanks @evshiron
      new support for full offline mode (without sdnext server running)
• Themes
  • all built-in themes are fully supported:
    • black-teal (default), light-teal, black-orange, invoked, amethyst-nightfall, midnight-barbie
  • if youre using any gradio default themes or a 3rd party theme or that are not optimized for SD.Next, you may experience issues
    default minimal style has been updated for compatibility, but actual styling is completely outside of SD.Next control

Update for 2023-09-13

Started as a mostly a service release with quite a few fixes, but then...
Major changes how hires works as well as support for a very interesting new model Wuerstchen

• tons of fixes
• changes to hires
  • enable non-latent upscale modes (standard upscalers)
  • when using latent upscale, hires pass is run automatically
  • when using non-latent upscalers, hires pass is skipped by default
    enabled using force hires option in ui
    hires was not designed to work with standard upscalers, but i understand this is a common workflow
  • when using refiner, upscale/hires runs before refiner pass
  • second pass can now also utilize full/quick vae quality
  • note that when combining non-latent upscale, hires and refiner output quality is maximum,
    but operations are really resource intensive as it includes: base->decode->upscale->encode->hires->refine
  • all combinations of: decode full/quick + upscale none/latent/non-latent + hires on/off + refiner on/off
    should be supported, but given the number of combinations, issues are possible
  • all operations are captured in image metadata
• diffusers:
  • allow loading of sd/sdxl models from safetensors without online connectivity
  • support for new model: wuerstchen
    its a high-resolution model (1024px+) thats ~40% faster than sd-xl with a bit lower resource requirements
    go to models -> huggingface -> search "warp-ai/wuerstchen" -> download
    its nearly 12gb in size, so be patient :)
• minor re-layout of the main ui
• updated ui hints
• updated models -> civitai
  • search and download loras
  • find previews for already downloaded models or loras
• new option inference mode
  • default is standard torch.no_grad
    new option is torch.inference_only which is slightly faster and uses less vram, but only works on some gpus
• new cmdline param --no-metadata
  skips reading metadata from models that are not already cached
• updated gradio
• styles support for subfolders
• css optimizations
• clean-up logging
  • capture system info in startup log
  • better diagnostic output
  • capture extension output
  • capture ldm output
  • cleaner server restart
  • custom exception handling

Update for 2023-09-06

One week later, another large update!

• system:
  • full python 3.11 support
    note that changing python version does require reinstall
    and if youre already on python 3.10, really no need to upgrade
• themes:
  • new default theme: black-teal
  • new light theme: light-teal
  • new additional theme: midnight-barbie, thanks @nyxia
• extra networks:
  • support for tags
    show tags on hover, search by tag, list tags, add to prompt, etc.
  • styles are now also listed as part of extra networks
    existing styles.csv is converted upon startup to individual styles inside models/style
    this is stage one of new styles functionality
    old styles interface is still available, but will be removed in future
  • cache file lists for much faster startup
    speedups are 50+% for large number of extra networks
  • ui refresh button now refreshes selected page, not all pages
  • simplified handling of descriptions
    now shows on-mouse-over without the need for user interaction
  • metadata and info buttons only show if there is actual content
• diffusers:
  • add full support for textual inversions (embeddings)
    this applies to both sd15 and sdxl
    thanks @ai-casanova for porting compel/sdxl code
  • mix&match base and refiner models (experimental):
    most of those are "because why not" and can result in corrupt images, but some are actually useful
    also note that if youre not using actual refiner model, you need to bump refiner steps
    as normal models are not designed to work with low step count
    and if youre having issues, try setting prompt parser to "fixed attention" as majority of problems
    are due to token mismatches when using prompt attention
    • any sd15 + any sd15
    • any sd15 + sdxl-refiner
    • any sdxl-base + sdxl-refiner
    • any sdxl-base + any sd15
    • any sdxl-base + any sdxl-base
  • ability to interrupt (stop/skip) model generate
  • added aesthetics score setting (for sdxl)
    used to automatically guide unet towards higher pleasing images
    highly recommended for simple prompts
  • added force zeros setting
    create zero-tensor for prompt if prompt is empty (positive or negative)
• general:
  • rembg remove backgrounds support for is-net model
  • settings now show markers for all items set to non-default values
  • metadata refactored how/what/when metadata is added to images
    should result in much cleaner and more complete metadata
  • pre-create all system folders on startup
  • handle model load errors gracefully
  • improved vram reporting in ui
  • improved script profiling (when running in debug mode)

Update for 2023-08-30

Time for a quite a large update that has been leaking bit-by-bit over the past week or so...
Note: due to large changes, it is recommended to reset (delete) your ui-config.json

• diffusers:
  • support for distilled sd models
    just go to models/huggingface and download a model, for example:
    segmind/tiny-sd, segmind/small-sd, segmind/portrait-finetuned
    those are lower quality, but extremely small and fast
    up to 50% faster than sd 1.5 and execute in as little as 2.1gb of vram
• general:
  • redesigned settings
    • new layout with separated sections:
      settings, ui config, licenses, system info, benchmark, models
    • system info tab is now part of settings
      when running outside of sdnext, system info is shown in main ui
    • all system and image paths are now relative by default
    • add settings validation when performing load/save
    • settings tab in ui now shows settings that are changed from default values
    • settings tab switch to compact view
  • update gradio major version
    this may result in some smaller layout changes since its a major version change
    however, browser page load is now much faster
  • optimizations:
    • optimize model hashing
    • add cli param --skip-all that skips all installer checks
      use at personal discretion, but it can be useful for bulk deployments
    • add model precompile option (when model compile is enabled)
    • extra network folder info caching
      results in much faster startup when you have large number of extra networks
    • faster xyz grid switching
      especially when using different checkpoints
  • update second pass options for clarity
  • models:
    • civitai download missing model previews
  • add openvino (experimental) cpu optimized model compile and inference
    enable with --use-openvino
    thanks @disty0
  • enable batch img2img scale-by workflows
    now you can batch process with rescaling based on each individual original image size
  • fixes:
    • fix extra networks previews
    • css fixes
    • improved extensions compatibility (e.g. sd-cn-animation)
    • allow changing vae on-the-fly for both original and diffusers backend

Update for 2023-08-20

Another release thats been baking in dev branch for a while...

• general:
  • caching of extra network information to enable much faster create/refresh operations
    thanks @midcoastal
• diffusers:
  • add hires support (experimental)
    applies to all model types that support img2img, including sd and sd-xl
    also supports all hires upscaler types as well as standard params like steps and denoising strength
    when used with sd-xl, it can be used with or without refiner loaded
    how to enable - there are no explicit checkboxes other than second pass itself:
    • hires: upscaler is set and target resolution is not at default
    • refiner: if refiner model is loaded
  • images save options: before hires, before refiner
  • redo move model to cpu logic in settings -> diffusers to be more reliable
    note that system defaults have also changed, so you may need to tweak to your liking
  • update dependencies

Update for 2023-08-17

Smaller update, but with some breaking changes (to prepare for future larger functionality)...

• general:
  • update all metadata saved with images
    see https://github.com/vladmandic/automatic/wiki/Metadata for details
  • improved amd installer with support for navi 2x & 3x and rocm 5.4/5.5/5.6
    thanks @evshiron
  • fix img2img resizing (applies to original, diffusers, hires)
  • config change: main config.json no longer contains entire configuration
    but only differences from defaults (similar to recent change performed to ui-config.json)
• diffusers:
  • enable batch img2img workflows
• original:
  • new samplers: dpm++ 3M sde (standard and karras variations)
    enable in settings -> samplers -> show samplers
  • expose always/never discard penultimate sigma
    enable in settings -> samplers

Update for 2023-08-11

This is a big one thats been cooking in dev for a while now, but finally ready for release...

• diffusers:
  • pipeline autodetect if pipeline is set to autodetect (default for new installs), app will try to autodetect pipeline based on selected model
    this should reduce user errors such as loading sd-xl model when sd pipeline is selected
  • quick vae decode as alternative to full vae decode which is very resource intensive
    quick decode is based on taesd and produces lower quality, but its great for tests or grids as it runs much faster and uses far less vram
    disabled by default, selectable in txt2img/img2img -> advanced -> full quality
  • prompt attention for sd and sd-xl
    supports both full parser and native compel
    thanks @ai-casanova
  • advanced lora load/apply methods
    in addition to standard lora loading that was recently added to sd-xl using diffusers, now we have
    • sequential apply (load & apply multiple loras in sequential manner) and
    • merge and apply (load multiple loras and merge before applying to model)
      see settings -> diffusers -> lora methods
      thanks @hameerabbasi and @ai-casanova
  • sd-xl vae from safetensors now applies correct config
    result is that 3rd party vaes can be used without washed out colors
  • options for optimized memory handling for lower memory usage
    see settings -> diffusers
• general:
  • new civitai model search and download
    native support for civitai, integrated into ui as models -> civitai
  • updated requirements
    this time its a bigger change so upgrade may take longer to install new requirements
  • improved extra networks performance with large number of networks

Update for 2023-08-05

Another minor update, but it unlocks some cool new items...

• diffusers:
  • vaesd live preview (sd and sd-xl)
  • fix inpainting (sd and sd-xl)
• general:
  • new torch 2.0 with ipex (intel arc)
  • additional callbacks for extensions
    enables latest comfyui extension

Update for 2023-07-30

Smaller release, but IMO worth a post...

• diffusers:
  • sd-xl loras are now supported!
  • memory optimizations: Enhanced sequential CPU offloading, model CPU offload, FP16 VAE
    • significant impact if running SD-XL (for example, but applies to any model) with only 8GB VRAM
  • update packages
• minor bugfixes

Update for 2023-07-26

This is a big one, new models, new diffusers, new features and updated UI...

First, SD-XL 1.0 is released and yes, SD.Next supports it out of the box!

• SD-XL Base
• SD-XL Refiner

Also fresh is new Kandinsky 2.2 model that does look quite nice:

• Kandinsky Decoder
• Kandinsky Prior

Actual changelog is:

• general:

  • new loading screens and artwork
  • major ui simplification for both txt2img and img2img
    nothing is removed, but you can show/hide individual sections
    default is very simple interface, but you can enable any sections and save it as default in settings
  • themes: add additional built-in theme, amethyst-nightfall
  • extra networks: add add/remove tags to prompt (e.g. lora activation keywords)
  • extensions: fix couple of compatibility items
  • firefox compatibility improvements
  • minor image viewer improvements
  • add backend and operation info to metadata

• diffusers:

  • were out of experimental phase and diffusers backend is considered stable
  • sd-xl: support for sd-xl 1.0 official model
  • sd-xl: loading vae now applies to both base and refiner and saves a bit of vram
  • sd-xl: denoising_start/denoising_end
  • sd-xl: enable dual prompts
    dual prompt is used if set regardless if refiner is enabled/loaded
    if refiner is loaded & enabled, refiner prompt will also be used for refiner pass
    • primary prompt goes to OpenAI CLIP-ViT/L-14
    • refiner prompt goes to OpenCLIP-ViT/bigG-14
  • kandinsky 2.2 support
    note: kandinsky model must be downloaded using model downloader, not as safetensors due to specific model format
  • refiner: fix batch processing
  • vae: enable loading of pure-safetensors vae files without config
    also enable automatic selection to work with diffusers
  • sd-xl: initial lora support
    right now this applies to official lora released by stability-ai, support for kohyas lora is expected soon
  • implement img2img and inpainting (experimental)
    actual support and quality depends on model
    it works as expected for sd 1.5, but not so much for sd-xl for now
  • implement limited stop/interrupt for diffusers works between stages, not within steps
  • add option to save image before refiner pass
  • option to set vae upcast in settings
  • enable fp16 vae decode when using optimized vae
    this pretty much doubles performance of decode step (delay after generate is done)

• original

  • fix hires secondary sampler
    this now fully obsoletes fallback_sampler and force_hr_sampler_name

Update for 2023-07-18

While were waiting for official SD-XL release, heres another update with some fixes and enhancements...

• global
  • image save: option to add invisible image watermark to all your generated images
    disabled by default, can be enabled in settings -> image options
    watermark information will be shown when loading image such as in process image tab
    also additional cli utility /cli/image-watermark.py to read/write/strip watermarks from images
  • batch processing: fix metadata saving, also allow to drag&drop images for batch processing
  • ui configuration: you can modify all ui default values from settings as usual,
    but only values that are non-default will be written to ui-config.json
  • startup: add cmd flag to skip all torch checks
  • startup: force requirements check on each server start
    there are too many misbehaving extensions that change system requirements
  • internal: safe handling of all config file read/write operations
    this allows sdnext to run in fully shared environments and prevents any possible configuration corruptions
• diffusers:
  • sd-xl: remove image watermarks autocreated by 0.9 model
  • vae: enable loading of external vae, documented in diffusers wiki
    and mix&match continues, you can even use sd-xl vae with sd 1.5 models!
  • samplers: add concept of default sampler to avoid needing to tweak settings for primary or second pass
    note that sampler details will be printed in log when running in debug level
  • samplers: allow overriding of sampler beta values in settings
  • refiner: fix refiner applying only to first image in batch
  • refiner: allow using direct latents or processed output in refiner
  • model: basic support for one more model: UniDiffuser
    download using model downloader: thu-ml/unidiffuser-v1
    and set resolution to 512x512

Update for 2023-07-14

Trying to unify settings for both original and diffusers backend without introducing duplicates...

• renamed hires fix to second pass
  as that is what it actually is, name hires fix is misleading to start with
• actual hires fix and refiner are now options inside second pass section
• obsoleted settings -> sampler -> force_hr_sampler_name
  it is now part of second pass options and it works the same for both original and diffusers backend
  which means you can use different scheduler settings for txt2img and hires if you want
• sd-xl refiner will run if its loaded and if second pass is enabled
  so you can quickly enable/disable refiner by simply enabling/disabling second pass
• you can mix&match model and refiner
  for example, you can generate image using sd 1.5 and still use sd-xl refiner as second pass
• reorganized settings -> samplers to show which section refers to which backend
• added diffusers lmsd sampler

Update for 2023-07-13

Another big one, but now improvements to both diffusers and original backends as well plus ability to dynamically switch between them!

• swich backend between diffusers and original on-the-fly
  • you can still use --backend <backend> and now that only means in which mode app will start, but you can change it anytime in ui settings
  • for example, you can even do things like generate image using sd-xl,
    then switch to original backend and perform inpaint using a different model
• diffusers backend:
  • separate ui settings for refiner pass with sd-xl
    you can specify: prompt, negative prompt, steps, denoise start
  • fix loading from pure safetensors files
    now you can load sd-xl from safetensors file or from huggingface folder format
  • fix kandinsky model (2.1 working, 2.2 was just released and will be soon)
• original backend:
  • improvements to vae/unet handling as well as cross-optimization heads
    in non-technical terms, this means lower memory usage and higher performance
    and you should be able to generate higher resolution images without any other changes
• other:
  • major refactoring of the javascript code
    includes fixes for text selections and navigation
  • system info tab now reports on nvidia driver version as well
  • minor fixes in extra-networks
  • installer handles origin changes for submodules

big thanks to @huggingface team for great communication, support and fixing all the reported issues asap!

Update for 2023-07-10

Service release with some fixes and enhancements:

• diffusers:
  • option to move base and/or refiner model to cpu to free up vram
  • model downloader options to specify model variant / revision / mirror
  • now you can download fp16 variant directly for reduced memory footprint
  • basic img2img workflow (sketch and inpaint are not supported yet)
    note that sd-xl img2img workflows are architecturaly different so it will take longer to implement
  • updated hints for settings
• extra networks:
  • fix corrupt display on refesh when new extra network type found
  • additional ui tweaks
  • generate thumbnails from previews only if preview resolution is above 1k
• image viewer:
  • fixes for non-chromium browsers and mobile users and add option to download image
  • option to download image directly from image viewer
• general
  • fix startup issue with incorrect config
  • installer should always check requirements on upgrades

Update for 2023-07-08

This is a massive update which has been baking in a dev branch for a while now

• merge experimental diffusers support

TL;DR: Yes, you can run SD-XL model in SD.Next now
For details, see Wiki page: Diffusers
Note this is still experimental, so please follow Wiki
Additional enhancements and fixes will be provided over the next few days
Thanks to @huggingface team for making this possible and our internal @team for all the early testing

Release also contains number of smaller updates:

• add pan & zoom controls (touch and mouse) to image viewer (lightbox)
• cache extra networks between tabs
  this should result in neat 2x speedup on building extra networks
• add settings -> extra networks -> do not automatically build extra network pages
  speeds up app start if you have a lot of extra networks and you want to build them manually when needed
• extra network ui tweaks

Update for 2023-07-01

Small quality-of-life updates and bugfixes:

• add option to disallow usage of ckpt checkpoints
• change lora and lyco dir without server restart
• additional filename template fields: uuid, seq, image_hash
• image toolbar is now shown only when image is present
• image Zip button gone and its not optional setting that applies to standard Save button
• folder Show button is present only when working on localhost,
  otherwise its replaced with Copy that places image URLs on clipboard so they can be used in other apps

Update for 2023-06-30

A bit bigger update this time, but contained to specific areas...

• change in behavior
  extensions no longer auto-update on startup
  using --upgrade flag upgrades core app as well as all submodules and extensions
• live server log monitoring in ui
  configurable via settings -> live preview
• new extra networks interface
  note: if youre using a 3rd party ui extension for extra networks, it will likely need to be updated to work with new interface
  • display in front of main ui, inline with main ui or as a sidebar
  • lazy load thumbnails
    drastically reduces load times for large number of extra networks
  • auto-create thumbnails from preview images in extra networks in a background thread
    significant load time saving on subsequent restarts
  • support for info files in addition to description files
  • support for variable aspect-ratio thumbnails
  • new folder view
• extensions sort by trending
• add requirements check for training

Update for 2023-06-26

• new training tab interface
  • redesigned preprocess, train embedding, train hypernetwork
• new models tab interface
  • new model convert functionality, thanks @akegarasu
  • new model verify functionality
• lot of ipex specific fixes/optimizations, thanks @disty0

Update for 2023-06-20

This one is less relevant for standard users, but pretty major if youre running an actual server
But even if not, it still includes bunch of cumulative fixes since last release - and going by number of new issues, this is probably the most stable release so far... (next one is not going to be as stable, but it will be fun :) )

• minor improvements to extra networks ui
• more hints/tooltips integrated into ui
• new dedicated api server
  • but highly promising for high throughput server
• improve server logging and monitoring with
  • server log file rotation
  • ring buffer with api endpoint /sdapi/v1/log
  • real-time status and load endpoint /sdapi/v1/system-info/status

Update for 2023-06-14

Second stage of a jumbo merge from upstream plus few minor changes...

• simplify token merging
• reorganize some settings
• all updates from upstream: A1111 v1.3.2 [df004be] (latest release)
  pretty much nothing major that i havent released in previous versions, but its still a long list of tiny changes
  • skipped/did-not-port:
    add separate hires prompt: unnecessarily complicated and spread over large number of commits due to many regressions
    allow external scripts to add cross-optimization methods: dangerous and i dont see a use case for it so far
    load extension info in threads: unnecessary as other optimizations ive already put place perform equally good
  • broken/reverted:
    sub-quadratic optimization changes

Update for 2023-06-13

Just a day later and one bigger update... Both some new functionality as well as massive merges from upstream

• new cache for models/lora/lyco metadata: metadata.json
  drastically reduces disk access on app startup
• allow saving/resetting of ui default values
  settings -> ui defaults
• ability to run server without loaded model
  default is to auto-load model on startup, can be changed in settings -> stable diffusion
  if disabled, model will be loaded on first request, e.g. when you click generate
  useful when you want to start server to perform other tasks like upscaling which do not rely on model
• updated accelerate and xformers
• huge nubmer of changes ported from A1111 upstream
  this was a massive merge, hopefully this does not cause any regressions
  and still a bit more pending...

Update for 2023-06-12

• updated ui labels and hints to improve clarity and provide some extra info
  this is 1st stage of the process, more to come...
  if you want to join the effort, see https://github.com/vladmandic/automatic/discussions/1246
• new localization and hints engine
  how hints are displayed can be selected in settings -> ui
• reworked installer sequence
  as some extensions are loading packages directly from their preload sequence
  which was preventing some optimizations to take effect
• updated settings tab functionality, thanks @gegell
  with real-time monitor for all new and/or updated settings
• launcher will now warn if application owned files are modified
  you are free to add any user files, but do not modify app files unless youre sure in what youre doing
• add more profiling for scripts/extensions so you can see what takes time
  this applies both to initial load as well as execution
• experimental sd_model_dict setting which allows you to load model dictionary
  from one model and apply weights from another model specified in sd_model_checkpoint
  results? who am i to judge :)

Update for 2023-06-05

Few new features and extra handling for broken extensions
that caused my phone to go crazy with notifications over the weekend...

• added extra networks to xyz grid options
  now you can have more fun with all your embeddings and loras :)
• new vae decode method to help with larger batch sizes, thanks @bigdog
• new setting -> lora -> use lycoris to handle all lora types
  this is still experimental, but the goal is to obsolete old built-in lora module
  as it doesnt understand many new loras and built-in lyco module can handle it all
• somewhat optimize browser page loading
  still slower than id want, but gradio is pretty bad at this
• profiling of scripts/extensions callbacks
  you can now see how much or pre/post processing is done, not just how long generate takes
• additional exception handling so bad exception does not crash main app
• additional background removal models
• some work on bfloat16 which nobody really should be using, but why not 🙂

Update for 2023-06-02

Some quality-of-life improvements while working on larger stuff in the background...

• redesign action box to be uniform across all themes
• add pause option next to stop/skip
• redesigned progress bar
• add new built-in extension: agent-scheduler
  very elegant way to getting full queueing capabilities, thank @artventurdev
• enable more image formats
  note: not all are understood by browser so previews and images may appear as blank
  unless you have some browser extensions that can handle them
  but they are saved correctly. and cant beat raw quality of 32-bit tiff or psd :)
• change in behavior: xformers will be uninstalled on startup if they are not active
  if you do have xformers selected as your desired cross-optimization method, then they will be used
  reason is that a lot of libaries try to blindly import xformers even if they are not selected or not functional

Update for 2023-05-30

Another bigger one...And more to come in the next few days...

• new live preview mode: taesd
  i really like this one, so its enabled as default for new installs
• settings search feature
• new sampler: dpm++ 2m sde
• fully common save/zip/delete (new) options in all tabs
  which (again) meant rework of process image tab
• system info tab: live gpu utilization/memory graphs for nvidia gpus
• updated controlnet interface
• minor style changes
• updated lora, swinir, scunet and ldsr code from upstream
• start of merge from a1111 v1.3

Update for 2023-05-26

Some quality-of-life improvements...

• updated README
• created CHANGELOG
  this will be the source for all info about new things moving forward
  and cross-posted to Discussions#99 as well as discord announcements
• optimize model loading on startup
  this should reduce startup time significantly
• set default cross-optimization method for each platform backend
  applicable for new installs only
  • cuda => Scaled-Dot-Product
  • rocm => Sub-quadratic
  • directml => Sub-quadratic
  • ipex => invokeais
  • mps => Doggettxs
  • cpu => Doggettxs
• optimize logging
• optimize profiling
  now includes startup profiling as well as cuda profiling during generate
• minor lightbox improvements
• bugfixes...i dont recall when was a release with at least several of those

other than that - first stage of Diffusers integration is now in master branch
i dont recommend anyone to try it (and dont even think reporting issues for it)
but if anyone wants to contribute, take a look at project page

Update for 2023-05-23

Major internal work with perhaps not that much user-facing to show for it ;)

• update core repos: stability-ai, taming-transformers, k-diffusion, blip, codeformer
  note: to avoid disruptions, this is applicable for new installs only
• tested with torch 2.1, cuda 12.1, cudnn 8.9
  (production remains on torch2.0.1+cuda11.8+cudnn8.8)
• fully extend support of --data-dir
  allows multiple installations to share pretty much everything, not just models
  especially useful if you want to run in a stateless container or cloud instance
• redo api authentication
  now api authentication will use same user/pwd (if specified) for ui and strictly enforce it using httpbasicauth
  new authentication is also fully supported in combination with ssl for both sync and async calls
  if you want to use api programatically, see examples in cli/sdapi.py
• add dark/light theme mode toggle
• redo some clip-skip functionality
• better matching for vae vs model
• update to xyz grid to allow creation of large number of images without creating grid itself
• update gradio (again)
• more prompt parser optimizations
• better error handling when importing image settings which are not compatible with current install
  for example, when upscaler or sampler originally used is not available
• fixes...amazing how many issues were introduced by porting a1111 v1.20 code without adding almost no new functionality
  next one is v1.30 (still in dev) which does bring a lot of new features

Update for 2023-05-17

This is a massive one due to huge number of changes,
but hopefully it will go ok...

• new prompt parsers
  select in UI -> Settings -> Stable Diffusion
  • Full: my new implementation
  • A1111: for backward compatibility
  • Compel: as used in ComfyUI and InvokeAI (a.k.a Temporal Weighting)
  • Fixed: for really old backward compatibility
• monitor extensions install/startup and
  log if they modify any packages/requirements
  this is a deep-experimental python hack, but i think its worth it as extensions modifying requirements
  is one of most common causes of issues
• added --safe command line flag mode which skips loading user extensions
  please try to use it before opening new issue
• reintroduce --api-only mode to start server without ui
• port all upstream changes from A1111
  up to today - commit hash 89f9faa

Update for 2023-05-15

• major work on prompt parsing this can cause some differences in results compared to what youre used to, but its all about fixes & improvements
  • prompt parser was adding commas and spaces as separate words and tokens and/or prefixes
  • negative prompt weight using [word:weight] was ignored, it was always 0.909
  • bracket matching was anything but correct. complex nested attention brackets are now working.
  • btw, if you run with --debug flag, youll now actually see parsed prompt & schedule
• updated all scripts in /cli
• add option in settings to force different latent sampler instead of using primary only
• add interrupt/skip capabilities to process images

Update for 2023-05-13

This is mostly about optimizations...

• improved torch-directml support
  especially interesting for amd users on windows where torch+rocm is not yet available
  dont forget to run using --use-directml or default is cpu
• improved compatibility with nvidia rtx 1xxx/2xxx series gpus
• fully working torch.compile with torch 2.0.1
  using inductor compile takes a while on first run, but does result in 5-10% performance increase
• improved memory handling
  for highest performance, you can also disable aggressive gc in settings
• improved performance
  especially after generate as image handling has been moved to separate thread
• allow per-extension updates in extension manager
• option to reset configuration in settings

Update for 2023-05-11

• brand new extension manager
  this is pretty much a complete rewrite, so new issues are possible
• support for torch 2.0.1
  note that if you are experiencing frequent hangs, this may be a worth a try
• updated gradio to 3.29.0
• added --reinstall flag to force reinstall of all packages
• auto-recover & re-attempt when --upgrade is requested but fails
• check for duplicate extensions

Update for 2023-05-08

Back online with few updates:

• bugfixes. yup, quite a lot of those
• auto-detect some cpu/gpu capabilities on startup
  this should reduce need to tweak and tune settings like no-half, no-half-vae, fp16 vs fp32, etc
• configurable order of top level tabs
• configurable order of scripts in txt2img and img2img
  for both, see sections in ui-> settings -> user interface

Update for 2023-05-04

Again, few days later...

• reviewed/ported all commits from A1111 upstream
  some a few are not applicable as i already have alternative implementations
  and very few i choose not to implement (save/restore last-known-good-config is a bad hack)
  otherwise, were fully up to date (it doesnt show on fork status as code merges were mostly manual due to conflicts)
  but...due to sheer size of the updates, this may introduce some temporary issues
• redesigned server restart function
  now available and working in ui
  actually, since server restart is now a true restart and not ui restart, it can be used much more flexibly
• faster model load
  plus support for slower devices via stream-load function (in ui settings)
• better logging
  this includes new --debug flag for more verbose logging when troubleshooting

Update for 2023-05-01

Been a bit quieter for last few days as changes were quite significant, but finally here we are...

• Updated core libraries: Gradio, Diffusers, Transformers
• Added support for Intel ARC GPUs via Intel OneAPI IPEX (auto-detected)
• Added support for TorchML (set by default when running on non-compatible GPU or on CPU)
• Enhanced support for AMD GPUs with ROCm
• Enhanced support for Apple M1/M2
• Redesigned command params: run webui --help for details
• Redesigned API and script processing
• Experimental support for multiple Torch compile options
• Improved sampler support
• Google Colab: https://colab.research.google.com/drive/126cDNwHfifCyUpCCQF9IHpEdiXRfHrLN
  Maintained by https://github.com/Linaqruf/sd-notebook-collection
• Fixes, fixes, fixes...

To take advantage of new out-of-the-box tunings, its recommended to delete your config.json so new defaults are applied. its not necessary, but otherwise you may need to play with UI Settings to get the best of Intel ARC, TorchML, ROCm or Apple M1/M2.

Update for 2023-04-27

a bit shorter list as:

• ive been busy with bugfixing
  there are a lot of them, not going to list each here.

  works for text and image generation, but not for process as there is no progress bar reported there to start with
• force unload xformers when not used
  improves compatibility with AMD/M1 platforms
• add styles.csv to UI settings to allow customizing path
• add --skip-git to cmd flags for power users that want
  to skip all git checks and operations and perform manual updates
• add --disable-queue to cmd flags that disables Gradio queues (experimental) this forces it to use HTTP instead of WebSockets and can help on unreliable network connections

This has been pending for a while, but finally uploaded some massive changes

• New launcher
  • webui.bat and webui.sh:
    Platform specific wrapper scripts that starts launch.py in Python virtual environment
    Note: Server can run without virtual environment, but it is recommended to use it
    This is carry-over from original repo
    If youre unsure which launcher to use, this is the one you want
  • launch.py:
    Main startup script
    Can be used directly to start server in manually activated venv or to run it without venv
  • installer.py:
    Main installer, used by launch.py
  • webui.py:
    Main server script
• New logger
• New exception handler
• Built-in performance profiler
• New requirements handling
• Move of most of command line flags into UI Settings
