The monthly Drupal core bug fix release window is this Wednesday, and since it has been a while since the last Drupal 7 bug fix release, I've decided to go ahead and plan to release Drupal 7.22 on that date. Per our release policy, this will be a bug fix release only (no security fixes).
The final patches for 7.22 have been committed and the code is frozen (excluding documentation fixes and fixes for any regressions that may be found in the next couple days). So, now is a wonderful time to update your development/staging servers to the latest 7.x code and help us catch any regressions in advance.
The relevant change records for Drupal 7.22 are listed below. This is not the full list of changes, rather only a list of notable API additions and data structure changes that might affect a number of other modules, so it's a good place to start looking for any problems:
- The Field API's memory usage has been optimized (includes recommended changes to contributed modules to leverage the changes)
- The Locale module has changed its handling of comment field language
- The number of parameters that can be passed by reference to drupal_alter() has changed (affects hook_file_download_access_alter() in Drupal 7 core)
- More Field API functions are allowed to act on a single field within an entity
You might also be interested in the tentative CHANGELOG.txt for Drupal 7.22 and the corresponding list of important issues that will be highlighted in the Drupal 7.22 release notes.
If you do find any regressions, please report them in the issue queue. Thanks!
Upcoming release windows after this week include:
- Wednesday, April 17 (security release window)
- Wednesday, May 1 (bug fix release window)
For more information on Drupal core release windows, see the documentation on release timing and security releases, and the discussion that led to this policy being implemented.
