        (/Coughs gravely./) Madam, when we last had this pleasure
        by the letter dated the sixteenth instant . . .


                              MRS BREEN

        Mr Bloom!  You down here in the haunts of sin!  I caught
        you nicely!  Scamp!

                                BLOOM
                   
        (/Hurridly./) Not so loud my name.  Whatever do you think
        me?  Don't give me away.  Walls have ears.  How do you do?
        It's ages since I.

                                             -- James Joyce, _Ulysses_

The third release candidate for Mixminion 0.0.4 is now available.
This release adds many bugfixes beyond Mixminion 0.0.4rc2.  If you're
running a server, you should upgrade.  (Just install the new software
and restart your server.)

With this release candidate, I have run out of pending issues for
Mixminion 0.0.4.  I'm going away for the weekend; when I come back on
Monday, I'm going to release 0.0.4final if there aren't any major bug
reports.

As usual, if you run into any problems with this release
candidate, please let me know.  I'll try to address them before
the final release.

NEW IN VERSION 0.0.4rc3:
   BUGFIXES:
   - Memory leaks:
       - Made server code release memory more aggressively.
       - Fixed a race condition where messages could be queued on a server
         connection that was already shutting down.
       - Fixed memory leaks on certificate checking.
   - Server bugs:
       - Fixed a server crash on key-rotation that would occur when to trying
         to open the same hash log db file twice.
       - Fixed bug that would crash server if PublicKeyLifetime changed.
       - Made server differentiate between ENOENT and EACCES when starting.
       - Fixed a bug that would cause key generation to happen at the wrong
         times.
   - Other bugs:
       - Fixed a bug related to using client keyrings without passwords.
       - Made ASCII armor more reliable in the face of extraneous space,
         headerless armor, and so on.

   OTHER CHANGES:

       - Commented most uncommented code.

   - Implementation quality
       - Improved a few log messages.
       - Made included etc/mixminiond.conf more reasonable by using a less
         aggressive retry schedule, commenting out unused Allow lines, and
         decreasing PublicKeyLifetime.
