- Rewritten messages caching (merged devel-mcache branch):
Indexes are stored in a separate table, so there's no need to store all messages in a folder Added threads data caching Flags are stored separately, so flag change doesn't cause DELETE+INSERT, just UPDATE - Partial QRESYNC support - Improved FETCH response handling - Improvements in response tokenization method
