+In IMAP, unseen-message counting and indexing is now done by SEARCH
+UNSEEN at the beginning of each poll or re-poll (rather than with
+the UNSEEN and RECENT responses and FLAGS queries on individual
+messages). This significantly cuts down on traffic to and from the
+server, and gives more reliable results.<p>
+
+<LI>
 The aka option now matches hostname suffixes, so (for example) saying
 `aka netaxs.com' will match not just netaxs.com but also (say)
 pop3.netaxs.com and mail.netaxs.com.

 Fetchmail can optionally use the RFC 2177 IDLE extension on an IMAP 
 server that supports it.
