http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc4.tar.gz http://dovecot.org/releases/1.2/rc/dovecot-1.2.rc4.tar.gz.sig I'm pretty hopeful that virtual mailbox code is finally crash-free. If people don't find many problems from this release, I'm thinking that rc5 could come in a couple of weeks and that would be renamed to v1.2.0 after a week or so if no one has reported bugs. v1.2.rc4 2009-05-17 Timo Sirainen <tss(a)iki.fi> * If /dev/arandom exists, use it instead of /dev/urandom (OpenBSD). * When logging to a file, the lines now start with a timestamp instead of "dovecot: " prefix. + IMAP: When multiple commands are pipelined, try harder to combine their mailbox syncing together. For example with Maildir pipelining STORE 1:* +FLAGS \Deleted and EXPUNGE commands the files won't be unnecessarily rename()d before being unlink()ed. + imap-proxy: Send backend's CAPABILITY if it's different from what was sent to client before. + IMAP: struct mail now keeps track of all kinds of statistics, such as number of open()s, stat()s, bytes read, etc. These fields could be exported by some kind of a statistics plugin (not included yet). + IMAP: SEARCH command now dynamically figures out how to run about 0.20 .. 0.25 seconds before seeing if there's other work to do. This makes the SEARCH performance much better. - Fixes to shared mailbox handling. - Fixes to virtual mailboxes. - THREAD command could have crashed. - Fixes to expire-tool. - mbox: Don't break if From_-line is preceded by CRLF (instead of LF). - dict process wasn't restarted after SIGHUP was sent to master.

v1.1.15 released
by Timo Sirainen 18 May '09

http://dovecot.org/releases/1.1/dovecot-1.1.15.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.15.tar.gz.sig The command pipelining fix is pretty interesting. Wonder how much it improves performance, especially when deleting lots of messages from a large mailbox. v1.1.15 2009-05-17 Timo Sirainen <tss(a)iki.fi> + IMAP: When multiple commands are pipelined, try harder to combine their mailbox syncing together. For example with Maildir pipelining STORE 1:* +FLAGS \Deleted and EXPUNGE commands the files won't be unnecessarily rename()d before being unlink()ed. - IMAP: SEARCH command was slower than necessary in a large mailbox. - deliver: When forwarding messages, if -f parameter was given, it should have been used as the Return-Path. - Maildir saving: Fixed race condition bugs in uidlist handling, causing files to be given new UIDs sometimes. - mbox: Don't crash when expunging all messages and file doesn't end with [CR]LF. - expire-tool: Use mail_uid and mail_gid settings if userdb doesn't return uid/gid. - Berkeley DB dict: Transaction rollbacking was implemented wrong. - zlib plugin: Some email / FETCH command combinations could have disconnected the client or sent compressed garbage.
