offlineimap (2.0.6) unstable; urgency=low
* Added support for holdconnectionopen and keepalive. This feature
allows for an IMAP server connection(s) to be held open until
the next sync process, permitting faster restart times.
* Another try at read-only folder support. This is nasty because I
have no way to test it and imaplib's read-only support is weird.
* Closing out old bug; fixed in 1.0.2. Closes: #150803.
* Optimized algorithm so that a SELECT is never issued for folders
that contain no messages.

offlineimap (2.0.5) unstable; urgency=low

# OfflineIMAP normally closes IMAP server connections between refreshes if
# the global option autorefresh is specified. If you wish it to keep the
# connection open, set this to true. If not specified, the default is
# false. Keeping the connection open means a faster sync start the
# next time and may use fewer server resources on connection, but uses
# more server memory. This setting has no effect if autorefresh is not set.
holdconnectionopen = no
# If you want to have "keepalives" sent while waiting between syncs,
# specify the amount of time IN SECONDS between keepalives here. Note that
# sometimes more than this amount of time might pass, so don't make it
# tight. This setting has no effect if autorefresh and holdconnectionopen
# are not both set.
