A new --search option was added, allowing you to select messages with the powerful IMAP SEARCH command. What can be done is selection by dates, any flag, From, Subject, body string, any Header, sizes, uids, etc. Bugs were fixed to better handle folder creation, so it's no longer a failure when a folder "already exists" during its creation. The way imapsync deals with headers was improved so that message duplicate issues are now rare. Reconnections are well done in TLS mode now. Many other small bugfixes and usability improvements were made. The default behavior is now the best one for most cases.
