Migrate 2.0 Beta 3
==================

Features and enhancements

- #989200 - Support "dynamic" migrations. Changes to be aware of:
All modules implementing migration classes must now implement hook_migrate_api()
(see migrate_migrate_api() for an example).
Dependencies and sourceMigrations must now be expressed in terms of
machine name rather than class name.
MigrationBase::getInstance now takes a machine name rather than a class name.
Migration class names are no longer required to end in 'Migration'.
- #992898 - Pass options to source and destination constructors as arrays.
File destinations (i.e., migrating directly to the file_managed table, with
option copying of the files themselves) are now supported.
Allow migration of comment enable/disable.
Check max_execution_time as well as memory_limit, for graceful exit when
max_execution_time is in play.
Add dedupe() method for a field mapping.
Apply MigrateBase::timestamp() to comment created/changed
