Drupal 7.30, xxxx-xx-xx (development version)

-----------------------

Drupal 7.29, 2014-07-16

----------------------

- Fixed security issues (multiple vulnerabilities). See SA-CORE-2014-003.

Drupal 7.28, 2014-05-08

-----------------------

- 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.

- Numerous small bug fixes.

- Numerous API documentation improvements.

- Additional automated test coverage.

Drupal 7.27, 2014-04-16

----------------------

- Fixed security issues (information disclosure). See SA-CORE-2014-002.

Drupal 7.26, 2014-01-15

----------------------

- Fixed security issues (multiple vulnerabilities). See SA-CORE-2014-001.

Drupal 7.25, 2014-01-02

-----------------------

- Fixed a bug in node_save() which prevented the saved node from being updated

in hook_node_insert() and other similar hooks.

- Added a meta tag to install.php to prevent it from being indexed by search

engines even when Drupal is installed in a subfolder (minor markup change).

- Fixed a bug in the database API that caused frequent deadlock errors when

running merge queries on some servers.

- Performance improvement: Prevented block rehashing from writing blocks to the

database on every cache clear and cron run when the blocks have not changed.

This fix results in an extra 'saved' key which is added and set to TRUE for

each block returned by _block_rehash() that actually is saved to the database

(data structure change).

- Added an optional 'skip on cron' parameter to hook_cron_queue_info() to allow

queues to avoid being automatically processed on cron runs (API addition).

- Fixed a bug which caused hook_block_view_MODULE_DELTA_alter() to never be

invoked if the block delta had a hyphen in it. To implement the hook when the

block delta has a hyphen, modules should now replace hyphens with underscores

when constructing the function name for the hook implementation.

- Fixed a bug which caused cached pages to sometimes be sent to the browser

with incorrect compression. The fix adds a new 'page_compressed' key to the

$cache->data array returned by drupal_page_get_cache() (minor data structure

change).

- Fixed broken tests on PHP 5.5.

- Made the File and Image modules more robust when saving entities that have

deleted files attached. The code in file_field_presave() will now remove the

record of the deleted file from the entity before saving (minor data

structure change).

- Standardized menu callback functions throughout Drupal core to return

MENU_NOT_FOUND and MENU_ACCESS_DENIED rather than printing their own "page

not found" or "access denied" pages (minor API change in the return value of

these functions under some circumstances).

- Fixed a bug in which caches were not properly cleared when a node was deleted

via the administrative interface.

- Changed the Bartik theme to render content contained in <pre>, <code> and

similar tags in a larger font size, so it is easier to read.

- Fixed a bug in the Search module that caused exceptions to be thrown during

searches if the server was not configured to represent decimal points as a

period.

- Fixed a regression in the Image module that made image_style_url() not work

when a relative path (rather than a complete file URI) was passed to it.

- Added an optional feature to the Statistics module to allow node views to be

tracked by Ajax requests rather than during the server-side generation of the

page. This allows the node counter to work on sites that use external page

caches (string change and new administrative option:

https://drupal.org/node/2164069).

- Added a link to the drupal.org documentation page for cron to the Cron

settings page (string change).

- Added a 'drupal_anonymous_user_object' variable to allow the anonymous user

object returned by drupal_anonymous_user() to be overridden with a classed

object (API addition).

- Changed the database API to allow inserts based on a SELECT * query to work

correctly.

- Changed the database schema of the {file_managed} table to allow Drupal to

manage files larger than 4 GB.

- Changed the File module's hook_field_load() implementation to prevent file

entity properties which have the same name as file or image field properties

from overwriting the field properties (minor API change).

- Numerous small bug fixes.

- Numerous API documentation improvements.

- Additional automated test coverage.

Drupal 7.24, 2013-11-20

----------------------

- Fixed security issues (multiple vulnerabilities), see SA-CORE-2013-003.

-----------------------

- Fixed a fatal error on PostgreSQL databases when updating the Taxonomy module

from Drupal 6 to Drupal 7.

- Fixed the default ordering of CSS files for sites using right-to-left

languages, to consistently place the right-to-left override file immediately

after the CSS it is overriding (API change: https://drupal.org/node/2058463).

- Added a drupal_check_memory_limit() API function to allow the memory limit to

be checked consistently (API addition).

- Changed the default web.config file for IIS servers to allow favicon.ico

files which are present in the filesystem to be accessed.

- Fixed inconsistent support for the 'tel' protocol in Drupal's URL filtering

functions.

- Performance improvement: Allowed all hooks to be included in the

module_implements() cache, even those that are only invoked on HTTP POST

requests.

- Made the database system replace truncate queries with delete queries when

inside a transaction, to fix issues with PostgreSQL and other databases.

- Fixed a bug which caused nested contextual links to display improperly.

- Fixed a bug which prevented cached image derivatives from being flushed for

private files and other non-default file schemes.

- Fixed drupal_render() to always return an empty string when there is no

output, rather than sometimes returning NULL (minor API change).

- Added protection to cache_clear_all() to ensure that non-cache tables cannot

be truncated (API addition: a new isValidBin() method has been added to the

default database cache implementation).

- Changed the default .htaccess file to support HTTP authorization in CGI

environments.

- Changed the password reset form to pre-fill the username when requested via a

URL query parameter, and used this in the error message that appears after a

failed login attempt (minor data structure and behavior change).

- Fixed broken support for foreign keys in the field API.

- Fixed "No active batch" error when a user cancels their own account.

- Added a description to the "access content overview" permission on the

permissions page (string change).

- Added a drupal_array_diff_assoc_recursive() function to allow associative

arrays to be compared recursively (API addition).

- Added human-readable labels to image styles, in addition to the existing

machine-readable name (API change: https://drupal.org/node/2058503).

- Moved the drupal_get_hash_salt() function to bootstrap.inc and used it in

additional places in the code, for added security in the case where there is

no hash salt in settings.php.

- Fixed a regression in Drupal 7.22 that caused internal server errors for

sites running on very old Apache 1.x web servers.

- Numerous small bug fixes.

- Numerous API documentation improvements.

- Additional automated test coverage.

Drupal 7.22, 2013-04-03

-----------------------

- 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: http://drupal.org/node/1825844).

- 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:

http://drupal.org/node/1915646).

- 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: http://drupal.org/node/1882722).

- Fixed broken support for translatable comment fields (API change:

http://drupal.org/node/1874724).

- 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).

- Fixed a bug in the States API which prevented certain types of form elements

from being disabled when requested.

- Allowed aggregator feed items with author names longer than 255 characters to

have a truncated version saved to the database (rather than causing a fatal

error).

(schema change which results in several columns in the Aggregator module's

database tables changing from VARCHAR to TEXT fields).

- Added hook_taxonomy_term_view() and standardized the process for rendering

taxonomy terms to invoke hook_entity_view() and otherwise make it consistent

with other entities (API change: http://drupal.org/node/1808870).

- Added hook_entity_view_mode_alter() to allow modules to change entity view

modes on display (API addition: http://drupal.org/node/1833086).

- Modified the Update manager module to allow drupal.org to collect usage

statistics for individual modules and themes, rather than only for entire

projects.

- Modified the node listing database query on Drupal's default front page to

add table aliases for better query altering (this is a data structure change

affecting code which implements hook_query_alter() on this query).

http://drupal.org/node/1626346).

- Added EntityFieldQuery support for taxonomy bundles.

- Fixed issue where field form structure was incomplete if field_access()

returned FALSE. Instead of being incomplete, the form structure now has

#access set to FALSE and field form validation is skipped (data structure

change: http://drupal.org/node/1663020).

- Fixed data loss issue due to field_has_data() returning inconsistent results.

The fix adds an optional DANGEROUS_ACCESS_CHECK_OPT_OUT tag to entity field

and other features.

* Added support for the SQLite database engine.

* Default to InnoDB engine, rather than MyISAM, on MySQL when available.

This offers increased scalability and data integrity.

- Security:

* Protected cron.php -- cron will only run if the proper key is provided.

* Implemented a pluggable password system and much stronger password hashes

that are compatible with the Portable PHP password hashing framework.

* Rate limited login attempts to prevent brute-force password guessing, and

improved the flood control API to allow variable time windows and

identifiers for limiting user access to resources.

* Transformed the "Update status" module into the "Update manager" which

can securely install or update modules and themes via a web interface.

- Usability:

* Added contextual links (a.k.a. local tasks) to page elements, such as

blocks, nodes, or comments, which allows to perform the most common tasks

with a single click only.

* Improved installer requirements check.

* Improved support for integration of WYSIWYG editors.

* Implemented drag-and-drop positioning for input format listings.

* Implemented drag-and-drop positioning for language listing.

* Implemented drag-and-drop positioning for poll options.

* Provided descriptions and human-readable names for user permissions.

* Removed comment controls for users.

* Removed display order settings for comment module. Comment display

order can now be customized using the Views module.

* Removed the 'related terms' feature from taxonomy module since this can

now be achieved with Field API.

* Added additional features to the default installation profile, and

implemented a "slimmed down" profile designed for developers.

* Added a built-in, automated cron run feature, which is triggered by site

visitors.

* Added an administrator role which is assigned all permissions for

installed modules automatically.

* Image toolkits are now provided by modules (rather than requiring a

manual file copy to the includes directory).

* Added an edit tab to taxonomy term pages.

* Redesigned password strength validator.

* Redesigned the add content type screen.

* Highlight duplicate URL aliases.

* Renamed "input formats" to "text formats".

* Moved text format permissions to the main permissions page.

* Added configurable ability for users to cancel their own accounts.

* Added "vertical tabs", a reusable interface component that features

automatic summaries and increases usability.

* Replaced fieldsets on node edit and add pages with vertical tabs.

- Performance:

* Improved performance on uncached page views by loading multiple core

objects in a single database query.

* Improved performance for logged-in users by reducing queries for path

alias lookups.

* Improved support for HTTP proxies (including reverse proxies), allowing

anonymous page views to be served entirely from the proxy.

- Documentation:

* Hook API documentation now included in Drupal core.

- News aggregator:

* Added OPML import functionality for RSS feeds.

* Optionally, RSS feeds may be configured to not automatically generate feed blocks.

- Search:

* Added support for language-aware searches.

- Aggregator:

* Introduced architecture that allows pluggable parsers and processors for

syndicating RSS and Atom feeds.

* Added options to suspend updating specific feeds and never discard feeds

items.

- Testing:

* Added test framework and tests.

- Improved time zone support:

* Drupal now uses PHP's time zone database when rendering dates in local

time. Site-wide and user-configured time zone offsets have been converted

to time zone names, e.g. Africa/Abidjan.

* In some cases the upgrade and install scripts do not choose the preferred

site default time zone. The automatically-selected time zone can be

corrected at admin/config/regional/settings.

* If your site is being upgraded from Drupal 6 and you do not have the

contributed date or event modules installed, user time zone settings will

fallback to the system time zone and will have to be reconfigured by each user.

* User-configured time zones now serve as the default time zone for PHP

date/time functions.

- Filter system:

* Revamped the filter API and text format storage.

* Added support for default text formats to be assigned on a per-role basis.

* Refactored the HTML corrector to take advantage of PHP 5 features.

- User system:

* Added clean API functions for creating, loading, updating, and deleting

user roles and permissions.

* Refactored the "access rules" component of user module: The user module

now provides a simple interface for blocking single IP addresses. The

previous functionality in the user module for restricting certain e-mail

addresses and usernames is now available as a contributed module. Further,

IP address range blocking is no longer supported and should be implemented

at the operating system level.

* Removed per-user themes: Contributed modules with similar functionality

are available.

- OpenID:

* Added support for Gmail and Google Apps for Domain identifiers. Users can

now login with their user@example.com identifier when example.com is powered

by Google.

* Made the OpenID module more pluggable.

- Added code registry:

* Using the registry, modules declare their includable files via their .info file,

allowing Drupal to lazy-load classes and interfaces as needed.

- Theme system:

* Removed the Bluemarine, Chameleon and Pushbutton themes. These themes live

on as contributed themes (http://drupal.org/project/bluemarine,

http://drupal.org/project/chameleon and http://drupal.org/project/pushbutton).

* Added Stark theme to make analyzing Drupal's default HTML and CSS easier.

* Added Seven as the default administration theme.

* Variable preprocessing of theme hooks prior to template rendering now goes

through two phases: a 'preprocess' phase and a new 'process' phase. See

http://api.drupal.org/api/function/theme/7 for details.

* Theme hooks implemented as functions (rather than as templates) can now

also have preprocess (and process) functions. See

http://api.drupal.org/api/function/theme/7 for details.

* Added Bartik as the default theme.

- File handling:

* Files are now first class Drupal objects with file_load(), file_save(),

and file_validate() functions and corresponding hooks.

* The file_move(), file_copy() and file_delete() functions now operate on

file objects and invoke file hooks so that modules are notified and can

respond to changes.

* For the occasions when only basic file manipulation are needed--such as

uploading a site logo--that don't require the overhead of databases and

hooks, the current unmanaged copy, move and delete operations have been

preserved but renamed to file_unmanaged_*().

* Rewrote file handling to use PHP stream wrappers to enable support for

both public and private files and to support pluggable storage mechanisms

and access to remote resources (e.g. S3 storage or Flickr photos).

* The mime_extension_mapping variable has been removed. Modules that need to

alter the default MIME type extension mappings should implement

hook_file_mimetype_mapping_alter().

* Added the hook_file_url_alter() hook, which makes it possible to serve

files from a CDN.

* Added a field specifically for uploading files, previously provided by

the contributed module FileField.

- Image handling:

* Improved image handling, including better support for add-on image

libraries.

* Added API and interface for creating advanced image thumbnails.

* Inclusion of additional effects such as rotate and desaturate.

* Added a field specifically for uploading images, previously provided by

the contributed module ImageField.

- Added aliased multi-site support:

* Added support for mapping domain names to sites directories.

- Added RDF support:

* Modules can declare RDF namespaces which are serialized in the <html> tag

for RDFa support.

* Modules can specify how their data structure maps to RDF.

* Added support for RDFa export of nodes, comments, terms, users, etc. and

their fields.

- Search engine optimization and web linking:

* Added a rel="canonical" link on node and comment pages to prevent

duplicate content indexing by search engines.

* Added a default rel="shortlink" link on node and comment pages that

advertises a short link as an alternative URL to third-party services.

* Meta information is now alterable by all modules before rendering.

- Field API:

* Custom data fields may be attached to nodes, users, comments and taxonomy

terms.

* Node bodies and teasers are now Field API fields instead of

being a hard-coded property of node objects.

* In addition, any other object type may register with Field API

and allow custom data fields to be attached to itself.

* Provides most of the features of the former Content Construction

Kit (CCK) module.

* Taxonomy terms are now Field API fields that can be added to any fieldable

object.

- Installer:

* Refactored the installer into an API that allows Drupal to be installed

via a command line script.

- Page organization

* Made the help text area a full featured region with blocks.

* Site mission is replaced with the highlighted content block region and

separate RSS feed description settings.

* The footer message setting was removed in favor of custom blocks.

* Made the main page content a block which can be moved and ordered

with other blocks in the same region.

* Blocks can now return structured arrays for later rendering just

like page callbacks.

- Translation system

* The translation system now supports message context (msgctxt).

* Added support for translatable fields to Field API.

- JavaScript changes

* Upgraded the core JavaScript library to jQuery version 1.4.4.

* Upgraded the jQuery Forms library to 2.52.

* Added jQuery UI 1.8.7, which allows improvements to Drupal's user

experience.

- Better module version support

* Modules now can specify which version of another module they depend on.

- Removed modules from core

* The following modules have been removed from core, because contributed

modules with similar functionality are available:

* Blog API module

* Ping module

* Throttle module

- Improved node access control system.

* All modules may now influence the access to a node at runtime, not just

the module that defined a node.

* Users may now be allowed to bypass node access restrictions without giving

them complete access to the site.

* Access control affects both published and unpublished nodes.

* Numerous other improvements to the node access system.

- Actions system

* Simplified definitions of actions and triggers.

* Removed dependency on the combination of hooks and operations. Triggers

now directly map to module hooks.

- Task handling

* Added a queue API to process many or long-running tasks.

* Added queue API support to cron API.

* Added a locking framework to coordinate long-running operations across

requests.
