## 5.1.0b1 (Unreleased)

**New features**
- We are now targeting the service's v3.1-preview API as the default. If you would like to still use version v3.0 of the service,
pass in `v3.0` to the kwarg `api_version` when creating your TextAnalyticsClient
- We have added an API `recognize_pii_entities` which returns entities containing personally identifiable information for a batch of documents. Only available for API version v3.1-preview and up.
- Added `offset` and `length` properties for `CategorizedEntity`, `SentenceSentiment`, and `LinkedEntityMatch`. These properties are only available for API versions v3.1-preview and up.
  - `length` is the number of characters in the text of these models
  - `offset` is the offset of the text from the start of the document
- We now have added support for opinion mining. To use this feature, you need to make sure you are using the service's
v3.1-preview API. To get this support pass `show_opinion_mining` as True when calling the `analyze_sentiment` endpoint
- Add property `bing_entity_search_api_id` to the `LinkedEntity` class. This property is only available for v3.1-preview and up, and it is to be
used in conjunction with the Bing Entity Search API to fetch additional relevant information about the returned entity.
