+Drupal 7.50, 2016-07-07 
+-----------------------
+- Added a new "administer fields" permission for trusted users, which is
+  required in addition to other permissions to use the field UI
+  (https://www.drupal.org/node/2483307).
+- Added clickjacking protection to Drupal core by setting the X-Frame-Options
+  header to SAMEORIGIN by default (https://www.drupal.org/node/2735873).
+- Added support for full UTF-8 (emojis, Asian symbols, mathematical symbols) on
+  MySQL and other database drivers when the site and database are configured to
+  allow it (https://www.drupal.org/node/2761183).
+- Improved performance by avoiding a re-scan of directories when a file is
+  missing; instead, trigger a PHP warning (minor API change:
+  https://www.drupal.org/node/2581445).
+- Made it possible to use any PHP callable in Ajax form callbacks, form API
+  form-building functions, and form API wrapper callbacks (API addition:
+  https://www.drupal.org/node/2761169).
+- Fixed that following a password reset link while logged in leaves users unable
+  to change their password (minor user interface change:
+  https://www.drupal.org/node/2759023).
+- Implemented various fixes for automated test failures on PHP 5.4+ and PHP 7.
+  Drupal core automated tests now pass in these environments.
+- Improved support for PHP 7 by fixing various problems.
+- Fixed various bugs with PHP 5.5+ imagerotate(), including when incorrect
+  color indices are passed in.
+- Fixed a regression introduced in Drupal 7.43 that allowed files uploaded by
+  anonymous users to be lost after form validation errors, and that also caused
+  regressions with certain contributed modules.
+- Fixed a regression introduced in Drupal 7.36 which caused the default value
+  of hidden textarea fields to be ignored.
+- Fixed robots.txt to allow search engines to access CSS, JavaScript and image
+  files.
+- Changed wording on the Update Manager settings page to clarify that the
+  option to check for disabled module updates also applies to uninstalled
+  modules (administrative-facing translatable string change).
+- Changed the help text when editing menu links and configuring URL redirect
+  actions so that it does not reference "Drupal" or the drupal.org website
+  (administrative-facing translatable string change).
+- Fixed the locale safety check that is used to ensure that translations are
+  safe to allow for tokens in the href/src attributes of translated strings.
+- Fixed that URL generation only works on port 80 when using domain based
+  language negotation.
+- Made method="get" forms work inside the administrative overlay. The fix adds
+  a new hidden field to these forms when they appear inside the overlay (minor
+  data structure change).
+- Increased maxlength of menu link title input fields in the node form and
+  menu link form from 128 to 255 characters.
+- Removed meaningless post-check=0 and pre-check=0 cache control headers from
+  Drupal HTTP responses.
+- Added a .editorconfig file to auto-configure editors that support it.
+- Added --directory option to run-tests.sh for easier test discovery of all
+  tests within a project.
+- Made run-tests.sh exit with a failure code when there are test fails or
+  problems running the script.
+- Fixed that cookies from previous tests are still present when a new test
+  starts in DrupalWebTestCase.
+- Improved performance of queries on the {authmap} database table.
+- Fixed handling of missing files and functions inside the registry.
+- Fixed Ajax handling for tableselect form elements that use checkboxes.
+- Fixed a bug which caused ip_address() to return nothing when the client IP
+  address and proxy IP address are the same.
+- Added a new option to format_xml_elements() to allow for already encoded
+  values.
+- Changed the {history} table's node ID field to be an unsigned integer, to
+  match the same field in the {node} table and to prevent errors with very
+  large node IDs.
+- Added an explicit page callback to the "admin/people/create" menu item in the
+  User module (minor data structure change). Previously this automatically
+  inherited the page callback from the parent "admin/people" menu item, which
+  broke contributed modules that override the "admin/people" page.
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
