I am pleased to announce the release of Cyrus IMAPd 2.4.1.  This is 
primarily a bugfix release to the 2.4 branch that fixes several bugs 
that were reported since the 2.4.0 release.

We recommend that anyone using 2.4.0 upgrade to 2.4.1.  Notable changes 
in the release are as follows:

- Fix cyrdump to work with -C for alternate config
- Change master to process all pending child messages once per loop, 
which fixes a DoS situation if there is too much message churn in a 
slower box - thanks to Henrique de Moraes Holschuh <hmh at>
- Reconstruct added flags -R, -U, -o, -O to give options handling 
corrupt or missing files
- Reconstruct fixed a pile of bugs, including a nasty one which created 
mailboxes with a UIDVALIDITY of 0
- Fixed EXPUNGE in murder
- Fixed LSUB where subscribed mailboxes are on different murder backends

contributions to this release.
