migrate 7.x-2.6

Migrate 2.6

IMPORTANT CHANGES SINCE MIGRATE 2.5

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 an $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 these methods are
deprecated.

Features and enhancements (since RC2)

- #2390229 - Make literal strings monolithic.
- #2391789 - Add extender getter to better support extending wizards.

Bug fixes (since RC2)

- #2391891 - idlist with XML source causes exception.
- #2314077 - Don't merge group dependencies into migration dependencies.
- #2392683 - Set vocabulary name (bundle) explicitly for term reference fields.
