Release notes

Maintenance release of the Drupal 7 series. Includes bugfixes 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.

Besides documentation fixes, 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 are two changes to the .htaccess file in this release:

  1. An improvement to the default rewrite rules to help avoid man-in-the-middle attacks on sites which are accessed over HTTP and HTTPS (see #1733476).
  2. A change to the list of file extensions which are blocked by .htaccess, to prevent temporary files created by text editors from being accessed (see #1907704). Note: This change may cause issues for sites running very old versions of the Apache web server (1.x); see the "Known issues" section below.

Upgrading custom versions of the .htaccess file is recommended.

Known issues:

#1962780: 500 Internal server error on Apache 1.x servers after updating to Drupal 7.22: Sites running on 1.x versions of the Apache web server may experience errors after updating to Drupal 7.22. (Although Apache 1.x was deprecated by the Apache project several years ago and switching to Apache 2.x is highly recommended, Drupal 7 normally does still run on it.) A patch to fix the problem is available in the above issue, and it has been committed to the 7.x development version so it will be included in the next bug fix release.

Major changes since 7.21:

  • 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:
  • 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.
  • Fixed a serious documentation bug: The $name variable in the taxonomy-term.tpl.php theme template was incorrectly documented as being sanitized when in fact it is not.
  • Fixed a bug which prevented Drupal 6 to Drupal 7 upgrades on sites which had duplicate permission names in the User module's database tables.
  • Added an empty "datatype" attribute to taxonomy term and username links to make the RDFa markup upward compatible with RDFa 1.1 (minor markup addition).
  • Fixed a bug which caused the denial-of-service protection added in Drupal 7.20 to break certain valid image URLs that had an extra slash in them.
  • Fixed a bug with update queries in the SQLite database driver that prevented Drupal from being installed with SQLite on PHP 5.4.
  • Fixed enforced dependencies errors updating to recent versions of Drupal 7 on certain non-MySQL databases.
  • Refactored the Field module's caching behavior to obtain large improvements in memory usage for sites with many fields and instances (API addition:
  • Fixed entity argument not being passed to implementations of hook_file_download_access_alter(). The fix adds an additional context parameter that can be passed when calling drupal_alter() for any hook (API change:
  • Fixed broken support for translatable comment fields (API change:
  • Added an assertThemeOutput() method to Simpletest to allow tests to check that themed output matches an expected HTML string (API addition).
  • Added a link to "Install another module" after a module has been successfully downloaded via the Update Manager (UI change).
  • Added an optional "exclusive" flag to installation profile .info files which allows Drupal distributions to force a profile to be selected during installation (API addition:
  • Fixed a bug which caused the database API to not properly close database connections.
  • Added a link to the URL for running cron from outside the site to the Cron settings page (UI change).
  • Fixed a bug which prevented image styles from being reverted on PHP 5.4.
  • Made the default .htaccess rules protocol sensitive to improve security for sites which use HTTPS and redirect between "www" and non-"www" versions of the page.
