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.
