<commit_before>
Drupal 7.23, xxxx-xx-xx (development version)
-----------------------
- Fixed a fatal error on PostgreSQL databases when updating the Taxonomy module
  from Drupal 6 to Drupal 7.
- Fixed the default ordering of CSS files for sites using right-to-left
  languages, to consistently place the right-to-left override file immediately
  after the CSS it is overriding (API change: https://drupal.org/node/2058463).
- Added a drupal_check_memory_limit() API function to allow the memory limit to
  be checked consistently (API addition).
- Changed the default web.config file for IIS servers to allow favicon.ico
  files which are present in the filesystem to be accessed.
- Fixed inconsistent support for the 'tel' protocol in Drupal's URL filtering
  functions.
- Performance improvement: Allowed all hooks to be included in the
  module_implements() cache, even those that are only invoked on HTTP POST
  requests.
- Made the database system replace truncate queries with delete queries when
  inside a transaction, to fix issues with PostgreSQL and other databases.
- Fixed a bug which caused nested contextual links to display improperly.
- Fixed a bug which prevented cached image derivatives from being flushed for
  private files and other non-default file schemes.
- Fixed drupal_render() to always return an empty string when there is no
  output, rather than sometimes returning NULL (minor API change).
- Added protection to cache_clear_all() to ensure that non-cache tables cannot
  be truncated (API addition: a new isValidBin() method has been added to the
  default database cache implementation).
- Changed the default .htaccess file to support HTTP authorization in CGI
  environments.
- Changed the password reset form to pre-fill the username when requested via a
  URL query parameter, and used this in the error message that appears after a
  failed login attempt (minor data structure and behavior change).
- Fixed broken support for foreign keys in the field API.
- Fixed "No active batch" error when a user cancels their own account.
- Added a description to the "access content overview" permission on the
  permissions page (string change).
- Added a drupal_array_diff_assoc_recursive() function to allow associative
  arrays to be compared recursively (API addition).
- Added human-readable labels to image styles, in addition to the existing
  machine-readable name (API change: https://drupal.org/node/2058503).
- Moved the drupal_get_hash_salt() function to bootstrap.inc and used it in
  additional places in the code, for added security in the case where there is
  no hash salt in settings.php.
- Fixed a regression in Drupal 7.22 that caused internal server errors for
  sites running on very old Apache 1.x web servers.

Drupal 7.22, 2013-04-03
-----------------------
- Allowed the drupal_http_request() function to be overridden so that
  additional HTTP request capabilities can be added by contributed modules.
- Changed the Simpletest module to allow PSR-0 test classes to be used in
  Drupal 7.
- Removed an unnecessary "Content-Disposition" header from private file
  downloads; it prevented many private files from being viewed inline in a web
  browser.
- Changed various field API functions to allow them to optionally act on a
  single field within an entity (API addition: http://drupal.org/node/1825844).
- Fixed a bug which prevented Drupal's file transfer functionality from working
  on some PHP 5.4 systems.
- Fixed incorrect log message when theme() is called for a theme hook that does
  not exist (minor string change).
- Fixed Drupal's token-replacement system to allow spaces in the token value.
- Changed the default behavior after a user creates a node they do not have
  access to view. The user will now be redirected to the front page rather than
  an access denied page.
- Fixed a bug which prevented empty HTTP headers (such as "0") from being set.
  (Minor behavior change: Callers of drupal_add_http_header() must now set
  FALSE explicitly to prevent a header from being sent at all; this was already
  indicated in the function's documentation.)
- Fixed OpenID errors when more than one module implements hook_openid(). The
  behavior is now changed so that if more than one module tries to set the same
  parameter, the last module's change takes effect.<commit_msg>Add standard information to CHANGELOG.txt in preparation for Drupal 7.23.<commit_after>
