drupal 7.33

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

No security fixes are included in this release.

Besides documentation fixes, 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:

• Some sites using a combination of Varnish and Nginx are reporting caching issues after updating to Drupal 7.33 (in which after logging out of the site, users may still see the logged-in version of the page in their browser). See #2381839: Changed date format for Last-Modified header breaks caching for Varnish/Nginx configs for further details.
• There is a performance regression after updating to Drupal 7.33 on sites that have code which tries to load a file that doesn't exist - this can cause a file system scan every time the code is called. Finding and fixing the offending code is the best solution. See #2380361: Latest tweaks to bootstrap.inc can make Drupal sluggish when there is code that tries to load a file that doesn't exist for further details.
• Sites using the References Dialog module and running PHP 5.3 or earlier may see a fatal error after upgrading to Drupal 7.33. This is due to a preexisting bug with that module which previously was only triggered in certain cases but now is triggered more generally. The solution is to apply the patch to the References Dialog module from #2315905: Recoverable fatal error: Argument 3 passed to l() must be an array, string given with references_dialog.
• A small number of sites are experiencing errors in update #7009 of the Block module when running database updates after this release. This appears to be because at some point in time these sites have modified the {block} table's database schema to allow NULL values in the title column, which conflicts with the update. It is not yet known what caused these sites to have a modified database schema. See #2378561: block_update_7009 fails with Warning: 1265 Data truncated for column 'title' at row 75 for further details, including a suggested workaround.

Major changes since 7.32:

• Added an entity_view_mode_prepare() API function to allow entity-defining modules to properly invoke hook_entity_view_mode_alter(), and used it throughout Drupal core to fix bugs with the invocation of that hook (API change: https://www.drupal.org/node/2369141).
• Added a "theme_hook_original" variable to templates and theme functions and an optional sitewide theme debug mode, to provide contextual information in the page's HTML to theme developers. The theme debug mode is based on the one used with Twig in Drupal 8 and can be accessed by setting the "theme_debug" variable to TRUE (API addition).
• Began storing the file modification time of each module and theme in the {system} database table so that contributed modules can use it to identify recently changed modules and themes (minor data structure change to the return value of system_get_info() and other related functions).
• Added a "Did you mean?" feature to the run-tests.sh script for running automated tests from the command line, to help developers who are attempting to run a particular test class or group.
• Changed the date format used in various HTTP headers output by Drupal core from RFC 1123 format to RFC 7231 format.
• Added a "block_cache_bypass_node_grants" variable to allow sites which have node access modules enabled to use the block cache if desired (API addition).
• Made image derivative generation HTTP requests return a 404 error (rather than a 500 error) when the source image does not exist.
• Fixed a bug which caused user pictures to be removed from the user object after saving, and resulted in data loss if the user account was subsequently re-saved.
• Fixed a bug in which field_has_data() did not return TRUE for fields that only had data in older entity revisions, leading to loss of the field's data when the field configuration was edited.
• Fixed a bug which caused the Ajax progress throbber to appear misaligned in many situatons (minor styling change).
• Prevented the Bartik theme from lower-casing the "Permalink" link on comments, for improved multilingual support (minor UI change).
• Added a "preferred_menu_links" tag to the database query that is used by menu_link_get_preferred() to find the preferred menu link for a given path, to make it easier to alter.
• Increased the maximum allowed length of block titles to 255 characters (database schema change to the {block} table).
• Removed the Field module's field_modules_uninstalled() function, since it did not do anything when it was invoked.
• Security improvement: Made the database API's orderBy() method sanitize the sort direction ("ASC" or "DESC") for queries built with db_select(), so that calling code does not have to.
• Changed the RDF module to consistently output RDF metadata for nodes and comments near where the node is rendered in the HTML (minor markup and data structure change).
• Added an HTML class to RDFa metatags throughout Drupal to prevent them from accidentally affecting the site appearance (minor markup change).
• Fixed a bug in the Unicode requirements check which prevented installing Drupal on PHP 5.6.
• Fixed a bug which caused drupal_get_bootstrap_phase() to abort the bootstrap when called early in the page request.
• Renamed the "Search result" view mode to "Search result highlighting input" to better reflect how it is used (UI change).
• Improved database queries generated by EntityFieldQuery in the case where delta or language condition groups are used, to reduce the number of INNER JOINs (this is a minor data structure change affecting code which implements hook_query_alter() on these queries).
• Removed special-case behavior for file uploads which allowed user #1 to bypass maximum file size and user quota limits.
