drupal 7.28

Maintenance release of the Drupal 7 series. Includes bug fixes and small API/feature improvements only (no major new functionality); significant new features are only being added to the forthcoming Drupal 8.0 release.

No security fixes are included in this release.

No changes have been made to the .htaccess, web.config, robots.txt or default settings.php files in this release, so upgrading custom versions of those files is not necessary.

Known issues:

Changes made to the Update Manager module in this release may lead to performance slowdowns in certain cases (including on rare page loads for site visitors, if the site is using the automated cron feature). See #952394: "No available releases found" - fetching update information exceeds timeout and the notes below for further details.

Major changes since 7.27:

• Fixed a regression introduced in Drupal 7.27 that caused JavaScript to break on older browsers (such as Internet Explorer 8 and earlier) when Ajax was used.
• Increased the timeout used by the Update Manager module when it fetches data from drupal.org (from 5 seconds to 30 seconds), to work around a problem which causes incomplete information about security updates to be presented to site administrators. This fix may lead to a performance slowdown on the Update Manager administration pages, when installing Drupal distributions, and (for sites that use the automated cron feature) on occasional page loads by site visitors.
• Fixed the behavior of the token system's "[node:summary]" token when the body field does not have a manual summary.
• Changed the behavior of db_query_temporary() so that it works on SELECT queries even when they have leading comments/whitespace. A side effect of this fix is that db_query_temporary() will now fail with an error if it is ever used on non-SELECT queries.
• Added a "node_admin_filter" tag to the database query used to build the list of nodes on the content administration page, to make it easier to alter.
• Made the cron queue system log any exceptions that are thrown while an item in the queue is being processed, rather than stopping the entire PHP request.
• Improved screen reader support by adding an aria-live HTML attribute to file upload fields when there is an error uploading the file (minor markup change).
• Made the pager on the Tracker module listing pages show the same number of items as other pagers throughout Drupal core (minor UI change).
• Fixed a bug which caused caches not to be properly cleared when a file entity was saved or deleted.
• Added several missing countries to the default list returned by country_get_list() (string change).
• Replaced the term "weight" with "influence" in the content ranking settings for search, and added help text for administrators (string change).
• Fixed untranslatable text strings in the administrative interface for the "Crop" effect provided by the Image module (minor string change).
• Fixed a bug in the Taxonomy module update function introduced in Drupal 7.26 that caused memory and CPU problems on sites with very large numbers of unpublished nodes.
