Maintenance release of the Drupal 7 series. Includes bug fixes and small API/feature improvements only (no major, non-backwards-compatible new functionality).
No security fixes are included in this release.
No changes have been made to the robots.txt or default settings.php files in this release, so upgrading custom versions of those files is not necessary.
There is one change to the .htaccess and web.config files in this release:
A change to block Composer-related files (in particular, composer.json and composer.lock) from being viewed by website visitors (see #2392153).
Upgrading custom versions of .htaccess and web.config to incorporate this change is recommended (especially if your site's codebase is built using Composer), but not required.
Known issues:
This release breaks autocomplete functionality on certain unusual server configurations that block direct access to Drupal's index.php file. See #2599326-30: Autocomplete function fails when index.html exist - After upgrading to Drupal 7.39 and chaos tools 1.8 and subsequent comments for further discussion and possible solutions.
Sites using the Client-side hierarchical select module may see PHP notices after updating to this release (see the issue for further details). The notices should be harmless but can be fixed by updating to a version of Client-side hierarchical select newer than the 7.x-1.0-beta4 release (for example, to the latest 7.x-1.x-dev version).
Major changes since 7.41:
#1191290: Stopped invoking hook_flush_caches() on every cron run, since some modules use that hook for expensive operations that are only needed on cache clears.
#2392153: Changed the default .htaccess and web.config to block Composer-related files.
#1443308: Added static caching to module_load_include() to improve performance.
#1919338: Fixed double-encoding bugs in select field widgets provided by the Options module. The fix deprecates the 'strip_tags' property on option widgets and replaces it with a new 'strip_tags_and_unescape' property (minor data structure change).
#2545480: Improved MySQL 5.7 support by changing the MySQL database driver to stop using the ANSI SQL mode alias, which has different meanings for different MySQL versions.
#2599326: Fixed a regression introduced in Drupal 7.39 which prevented autocomplete functionality from working on servers that are not configured to automatically recognize index.php.
#1414508: Updated the Archive_Tar PEAR package to the latest 1.4.0 release, to fix bugs with tar file handling on various operating systems.
#1289336: Fixed fatal errors on node preview when a field is displayed in the node teaser but hidden in the full node view. The fix removes a field_attach_prepare_view() call from the node_preview() function since it is redundant with one in the node preview theme layer.
#1862250: Improved the description of the "Trimmed" format option on text fields (translatable string change, and minor UI and data structure change).
