offlineimap (6.2.0) unstable; urgency=low
* FIX: Removed imaplib2 entirely. It was the cause of numerous
crash/hang bugs.
crash/hang bugs. Closes: #536156, #536329.
* REMOVAL: IDLE support had to be removed because it depended on
imaplib2.
* Do not request INTERNALDATE when it is not needed.

# You can also specify parameters to the commands

# If you have a limited amount of bandwidth available you can exclude larger
# messages (e.g. those with large attachments etc). If you do this it
# will appear to offlineimap that these messages do not exist at all. They
# will not be copied, have flags changed etc. For this to work on an IMAP
# server the server must have server side search enabled. This works with gmail
# and most imap servers (e.g. cyrus etc)
# The maximum size should be specified in bytes - e.g. 2000000 for approx 2MB
# maxsize = 2000000
# When you are starting to sync an already existing account yuo can tell offlineimap
# to sync messages from only the last x days. When you do this messages older than x
# days will be completely ignored. This can be useful for importing existing accounts
# when you do not want to download large amounts of archive email.
# Messages older than maxage days will not be synced, their flags will
# not be changed, they will not be deleted etc. For offlineimap it will be like these
# messages do not exist. This will perform an IMAP search in the case of IMAP or Gmail
# and therefor requires that the server support server side searching. This will
# calculate the earliest day that would be included in the search and include all
# messages from that day until today. e.g. maxage = 3 to sync only the last 3 days mail
# maxage = 3
