migrate 7.x-2.6-beta1

Migrate 2.6 Beta 1

Migration developers will need to add the "advanced migration information" permission to their roles to continue seeing all the info in the UI they're used to.

Auto-registration (having classes be registered just based on their class name, with no call to registerMigration or definition in hook_migrate_api()) is no longer supported. Registration of classes defined in hook_migrate_api() is no longer automatic - do a drush migrate-register or use the Register button in the UI to register them.

Migration class constructors should now always accept a $arguments array as the first parameter and pass it to its parent. This version does support legacy migrations which pass a group object, or nothing, but that support will be removed in a future version.

Features and enhancements

- #1826112 - A new API has been added to support external modules in developing easy-to-use wizard-based UIs.
- #1833380 - Major refactoring of the UI, breaking groups and migrations (tasks) into separate pages, introducing an advanced permission and presenting a simplified UI to those with only the basic permission.
- #1860450 - The UI now has the capability of spawning import/rollback operations in drush, with email notifications of completion. The notification ability is available when running drush at the command line, which may be useful for running imports via cron.
- #1996602 - A default field handler is now provided that should handle many if not most field types without custom handlers.
- #1901980 - Support encrypting particular arguments saved to the database, to support wizard implementations that may be prompting for secure database credentials.
- #1896096 - Add ability to define field mappings via arguments at registration time, and use those to override mappings in code.
- #1961620 - When editing field mappings, allow destination or source fields to be explicitly set DNM.
- #1996280 - Allow all field/subfields/options to be edited, and indent subfields/options to make the relationship more clear.
- #1996350 - Allow sourceMigration to be edited.
