+Drupal 7.51, 2016-10-05
+-----------------------
+- The Update module now also checks for updates to a disabled theme that is
+  used as an admin theme.
+- Exceptions thrown in dblog_watchdog() are now caught and ignored.
+- Clarified the warning that appears when modules are missing or have moved.
+- Log messages are now XSS filtered on display.
+- Draggable tables now work on touch screen devices.
+- Added a setting for allowing double underscores in CSS identifiers
+  (https://www.drupal.org/node/2810369).
+- If a user navigates away from a page while an Ajax request is running they
+  will no longer get an error message saying "An Ajax HTTP request terminated
+  abnormally".
+- The system_region_list() API function now takes an optional third parameter
+  which allows region name translations to be skipped when they are not needed
+  (API addition: https://www.drupal.org/node/2810365).
+- Numerous performance improvements.
+- Numerous bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
+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.
+
+Drupal 7.44, 2016-06-15
+-----------------------
+- Fixed security issues (privilege escalation). See SA-CORE-2016-002.
+
+Drupal 7.43, 2016-02-24
+-----------------------
+- Fixed security issues (multiple vulnerabilities). See SA-CORE-2016-001.
+
+Drupal 7.42, 2016-02-03
+-----------------------
+- 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.
+- Changed the default .htaccess and web.config to block Composer-related files.
+- Added static caching to module_load_include() to improve performance.
+- 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).
+- 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.
+- 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.
+- Updated the Archive_Tar PEAR package to the latest 1.4.0 release, to fix bugs
+  with tar file handling on various operating systems.
+- 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.
+- Improved the description of the "Trimmed" format option on text fields
+  (translatable string change, and minor UI and data structure change).
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
+Drupal 7.41, 2015-10-21
+-----------------------
+- Fixed security issues (open redirect). See SA-CORE-2015-004.
+
+Drupal 7.40, 2015-10-14
+-----------------------
+- Made Drupal's code for parsing .info files run much faster and use much less
+  memory.
+- Prevented drupal_http_request() from returning an error when it receives a
+  201 through 206 HTTP status code.
+- Added support for autoloading traits via the registry on sites running PHP
+  5.4 or higher.
+- Allowed the user-picture.tpl.php theme template to have HTML classes besides
+  the default "user-picture" class printed in it (markup change).
+- Fixed the URL text filter to convert e-mail addresses with plus signs into
+  mailto: links.
+- Added alternate text to file icons displayed by the File module, to improve
+  accessibility (string change, and minor API addition to theme_file_icon()).
+- Changed one-time login link failure messages to be displayed as errors or
+  warnings as appropriate, rather than as regular status messages (minor UI
+  change and data structure change).
+- Changed the default settings.php configuration to exclude private files from
+  the "404_fast_paths" behavior.
+- Changed the page that displays filter tips for a particular text format, for
+  example filter/tips/full_html, to return "page not found" or "access denied"
+  if the format does not exist or the user does not have access to it. This
+  change adds a new menu item to the Filter module's hook_menu() entry (minor
+  data structure change).
+- Added a new hook, hook_block_cid_parts_alter(), to allow modules to alter the
+  cache keys used for caching a particular block.
+- Made drupal_set_message() display and return messages when "0" is passed in
+  as the message to set.
+- Fixed non-functional "Files displayed by default" setting on file fields.
+- The "worker callback" provided in hook_cron_queue_info() and the "finished"
+  callback specified during batch processing can now be any PHP callable
+  instead of just functions.
+- Prevented drupal_set_time_limit() from decreasing the time limit in the case
+  where the PHP maximum execution time is already unlimited.
+- Changed the default thousand marker for numeric fields from a space ("1 000")
+  to nothing ("1000") (minor UI change: https://www.drupal.org/node/1388376).
+- Prevented malformed theme .info files (without a "name" key) from causing
+  exceptions during menu rebuilds. If an .info file without a "name" key is
+  found in a module or theme directory, Drupal will now use the module or
+  theme's machine name as the display name instead.
+- Made the format column in the {date_format_locale} database table
+  case-sensitive, to match the equivalent column in the {date_formats} table.
+- Fixed a bug in the Statistics module that caused JavaScript files attached to
+  a node while it is being viewed to be omitted from the page.
+- Added an optional 'project:' prefix that can be added to dependencies in a
+  module's .info file to indicate which project the dependency resides in (API
+  addition: https://www.drupal.org/node/2299747).
+- Fixed various bugs that occurred after hooks were invoked early in the Drupal
+  bootstrap and that caused module_implements() and drupal_alter() to cache an
+  incomplete set of hook implementations for later use.
+- Set the X-Content-Type-Options header to "nosniff" when possible, to prevent
+  certain web browsers from picking an unsafe MIME type.
+- Prevented the database API from executing multiple queries at once on MySQL,
+  if the site's PHP version is new enough to do so. This is a secondary defense
+  against SQL injection (API change: https://www.drupal.org/node/2463973).
+- Fixed a bug in the Drupal 6 to Drupal 7 upgrade path which caused the upgrade
+  to fail when there were multiple file records pointing to the same file.
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
+Drupal 7.39, 2015-08-19
+-----------------------
+- Fixed security issues (multiple vulnerabilities). See SA-CORE-2015-003.
+
+Drupal 7.38, 2015-06-17
+-----------------------
+- Fixed security issues (multiple vulnerabilities). See SA-CORE-2015-002.
+
+Drupal 7.37, 2015-05-07
+-----------------------
+- Fixed a regression in Drupal 7.36 which caused certain kinds of content types
+  to become disabled if they were defined by a no-longer-enabled module.
+- Removed a confusing description regarding automatic time zone detection from
+  the user account form (minor UI and data structure change).
+- Allowed custom HTML tags with a dash in the name to pass through filter_xss()
+  when specified in the list of allowed tags.
+- Allowed hook_field_schema() implementations to specify indexes for fields
+  based on a fixed-length column prefix (rather than the entire column), as was
+  already allowed in hook_schema() implementations.
+- Fixed PDO exceptions on PostgreSQL when accessing invalid entity URLs.
+- Added a sites/all/libraries folder to the codebase, with instructions for
+  using it.
+- Added a description to the "Administer text formats and filters" permission
+  on the Permissions page (string change).
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
+Drupal 7.36, 2015-04-01
+-----------------------
+- Added a 'file_public_schema' variable which allows modules that define
+  publicly-accessible streams in hook_stream_wrappers() to bypass file download
+  access checks when processing managed file upload fields.
+- Fixed a bug that caused database query tags not to be added to search-related
+  database queries under many circumstances, and which prevented the
+  corresponding hook_query_TAG_alter() implementations from being called.
+- Fixed the "for" attribute on managed file upload field labels to improve
+  accessibility (minor markup change).
+- Added a 'javascript_always_use_jquery' variable which can be set to FALSE by
+  sites that may not need jQuery loaded on all pages, and a 'requires_jquery'
+  option to drupal_add_js() which modules can set to FALSE when adding
+  JavaScript files that have no dependency on jQuery (API addition:
+  https://www.drupal.org/node/2462717).
+- Fixed incorrect foreign keys in the User module's role_permission and
+  users_roles database tables.
+- Changed permission descriptions throughout Drupal core to consistently link
+  to relevant administrative pages, regardless of whether the user viewing the
+  Permissions page can view the page being linked to (minor UI change).
+- Fixed the drupal_add_region_content() function so that it actually adds
+  content to the page.
+- Added an 'image_suppress_itok_output' variable to allow sites already using
+  the existing 'image_allow_insecure_derivatives' variable to also prevent
+  security tokens from appearing in image derivative URLs.
+- Fixed double-escaping of theme names in the Block module administrative
+  interface (minor string change).
+- Added basic support for Xdebug when running automated tests.
+- Fixed a bug which caused previewing a node to remove elements from the node
+  being edited. With this fix, calling node_preview() will no longer modify the
+  passed-in node object (minor API change).
+- Added a user_has_role() function to check whether a user has a particular
+  role (API addition: https://www.drupal.org/node/2462411).
+- Fixed installation failures when an opcode cache is enabled.
+- Fixed a bug in the Drupal 6 to Drupal 7 upgrade path which caused private
+  files to be inaccessible.
+- Fixed a bug in the Drupal 6 to Drupal 7 upgrade path which caused user
+  pictures to be lost.
+- Fixed missing language code in hook_field_attach_view_alter() when it is
+  invoked from field_view_field().
+- Stopped sending ETag and Last-Modified headers for uncached page requests,
+  since they break caching for certain Varnish and Nginx configurations.
+- Changed the Simpletest module to allow PSR-4 test classes to be used in
+  Drupal 7.
+- Fixed a fatal error that occurred when using the Comment module's "Unpublish
+  comment containing keyword(s)" action.
+- Changed the "lang" attribute on language links to "xml:lang" so it validates
+  as XHTML (minor markup change).
+- Prevented the form API from allowing arrays to be submitted for various form
+  elements, such as textfields, textareas, and password fields (API change:
+  https://www.drupal.org/node/2462723).
+- Fixed a bug in the Contact module which caused the global user object to have
+  the incorrect name and e-mail address during the remainder of the page
+  request after the contact form is submitted.
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.
+
+Drupal 7.35, 2015-03-18
+-----------------------
+- Fixed security issues (multiple vulnerabilities). See SA-CORE-2015-001.
+
+Drupal 7.34, 2014-11-19
+-----------------------
+- Fixed security issues (multiple vulnerabilities). See SA-CORE-2014-006.
+
+Drupal 7.33, 2014-11-07
+-----------------------
+- 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.
+- 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).
+- 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).
+- 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.
+- Numerous small bug fixes.
+- Numerous API documentation improvements.
+- Additional automated test coverage.

 /**
- * Parses a system URL string into an associative array suitable for url().
+ * Parses a URL string into its path, query, and fragment components.
 *
- * This function should only be used for URLs that have been generated by the
- * system, such as via url(). It should not be used for URLs that come from
- * external sources, or URLs that link to external resources.
+ * This function splits both internal paths like @code node?b=c#d @endcode and
+ * external URLs like @code https://example.com/a?b=c#d @endcode into their
+ * component parts. See
+ * @link http://tools.ietf.org/html/rfc3986#section-3 RFC 3986 @endlink for an
+ * explanation of what the component parts are.
 *
- * The returned array contains a 'path' that may be passed separately to url().
- * For example:
- * @code
- *   $options = drupal_parse_url($_GET['destination']);
- *   $my_url = url($options['path'], $options);
- *   $my_link = l('Example link', $options['path'], $options);
- * @endcode
+ * Note that, unlike the RFC, when passed an external URL, this function
+ * groups the scheme, authority, and path together into the path component.
 *
- * This is required, because url() does not support relative URLs containing a
- * query string or fragment in its $path argument. Instead, any query string
- * needs to be parsed into an associative query parameter array in
- * $options['query'] and the fragment into $options['fragment'].
+ * @param string $url
+ *   The internal path or external URL string to parse.
 *
- * @param $url
- *   The URL string to parse, f.e. $_GET['destination'].
+ * @return array
+ *   An associative array containing:
+ *   - path: The path component of $url. If $url is an external URL, this
+ *     includes the scheme, authority, and path.
+ *   - query: An array of query parameters from $url, if they exist.
+ *   - fragment: The fragment component from $url, if it exists.
 *
- * @return
- *   An associative array containing the keys:
- *   - 'path': The path of the URL. If the given $url is external, this includes
- *     the scheme and host.
