3.0.0-beta.1 - 2017-01-29

Added

• Ported all recent changes from Craft 2, including chart-related things added in Craft 2.6.
• Craft 3 now requires PHP 7.0.0 or later.
• Added an image editor to the Assets index page, with support for cropping, rotating, and flipping images, as well as setting focal points on them, which influences where images should be cropped for image transforms.
• Craft can now be installed via Composer: composer require craftcms/craft.
• Craft now supports installing plugins via Composer, with the help Craft CMS Composer Installer.
• Craft now checks for plugin info in a composer.json file, rather than plugin.json, for plugins that were manually installed in plugins/. (See the Craft CMS Composer Installer readme for details on how the info should be formatted.)
• Plugin icons now must be stored at the root of the plugin’s source directory.
• Plugin IDs are now kebab-case versions of their handles.
• Craft now automatically loads the vendor/autoload.php file (if it exists) for plugins that were manually installed.
• Added the bootstrap/ folder alongside the src/ folder, with new web.php and console.php bootstrap files.
• Added PostgreSQL support, which can be enabled by setting the driver setting in config/db.php to 'pgsql'.
• Added the update/run-pending-migrations controller action, which can be used as a post-deploy hook for deployment services like DeployBot, to get Craft to automatically run any pending migrations, minimizing site downtime.
• Added the backupCommand config setting, which can be used to override the command Craft executes when creating a database backup.
• Added the restoreCommand config setting, which can be used to override the command Craft executes when restoring a database backup.

• Added the schema DB config setting, which can be used to assign the default schema used when connecting to a PostgreSQL database.
• Added support for setting Volume config settings in config/volumes.php. The file should return an array with keys that match volume handles, and values that are config arrays for the volumes.
• It is now possible to override the default Guzzle settings from config/guzzle.php.
• Added the view global Twig variable, which is a reference to the View class that is rendering the template.
• Added craft.matrixBlocks(), which can be used to query for Matrix blocks.
• Added the SORT_ASC and SORT_DESC global Twig variables, which can be used to define query sorting in element queries.
• Added the POS_HEAD, POS_BEGIN, POS_END, POS_READY, and POS_LOAD global Twig variables, which can be used to define the placement of registered scripts.
• Added the className() global Twig function, which returns the class name of a given object.
• Added the |atom and |rss Twig filters, for formatting dates in Atom and RSS date formats, respectively.
• Added the |column Twig filter, for capturing the key/property values of a series of arrays/objects.

Changed

• The bootstrap script now assumes that the vendor/ folder is 3 levels up from the bootstrap/ directory by default (e.g. vendor/craftcms/cms/bootstrap/). If that is not the case (most likely because Craft had been symlinked into place), the CRAFT_VENDOR_PATH PHP constant can be used to correct that.

• Renamed the defaultFolderPermissions config setting to defaultDirMode.
• Renamed the useWriteFileLock config setting to useFileLocks.

• The Feed widget is now limited to show 5 articles by default.
• Element queries’ status params must now always be set to valid statuses, or the query won’t return any results.

• Test emails now mask the values for any Mailer transport type settings that include “key” or “password” in their setting name.
• The Control Panel page header is now fixed when scrolling down.
• Translatable fields are no longer marked as translatable when editing an element type that isn’t localizable (e.g. user accounts).

• The Craft.publishableSections Javascript array now includes info about each section’s entry types.
• craft\db\Connection::backup() now throws an exception if something goes wrong, rather than returning true or false. If no exception is thrown, it worked.
• craft\db\mysql\Schema::getTableNames() no longer only returns the table names with the right table prefix.

Added

• PluginClassName::getInstance() will now return the singular instance of the plugin class.

Removed

• Removed craft\dates\DateTime::format(), so it no longer has a $timezone argument and automatically sets the time zone on the DateTime object.

• Added support for config/app.php, which can return an array that will be merged with Craft’s core application config array.
• Craft now looks for translation files at translations/locale-ID/category.php, where category can either be 'app', 'site', 'yii', or a plugin’s handle.
• All user-defined strings in the Control Panel (e.g. section names) are now translated using the 'site' category, to prevent translation conflicts with Craft’s own Control Panel translations.
• Craft now uses SwiftMailer to send emails.

• Added craft\helpers\DateTimeHelper::toIso8601(), for converting a date (or date-formatted string) into an ISO-8601-formatted string.

• The registerjs tag now supports an on param for specifying when the JavaScript code should be executed. (Possible values are on ready and on load.) (The at and on parameters are mutually exclusive.)
• The registercss, registerhirescss, registercssfile, registercssresource, registerjsfile, and registerjsresource tags now support a with param, which can be set to an object that specifies additional attributes on the resulting tags (e.g. with { rel: "stylesheet" }).
• The t filter now always defaults to translating the given string using the 'site' category unless it is otherwise specified (e.g. myString|t('pluginhandle')).
