 - #708228 Scott Reynolds, alex_b: Break FeedsImportBatch into separate classes.
+  NOTE: FeedsFetcher implementations cannot use FeedsImportBatch directly
+  anymore but most provide their own implementation of FeedsImportBatch. See
+  FeedsHTTPFetcher.inc for an example.
 - alex_b: Support mapping to OpenID, using OpenID as a unique mapping target.
 - alex_b: Handle exceptions outside of Importer/Source facade methods.
-- #600584 alex_b: Use Batch API. NOTE: third party plugins/extensions
-  implementing FeedsProcessor::process(), FeedsProcessor::clear() or
-  FeedsImporter::expire() need to adjust their implementations. Modules that
-  directly use Feeds' API for importing or clearing sources need may want to
-  use feeds_batch_set() instead of feeds_source()->import() or
-  feeds_source()->clear().
