   * New option --all to archive all messages in a mailbox.  Closes: #1764846.
   * Fixed a crash when archiving maildirs with --days=0. (Thanks John Goerzen)
   * IMAP: automatically add NAMESPACE prefix to a mailbox path if necessary.
+  * Removed the feature to setuid to the mailbox owners when run as root.
+    This was a bad idea; it's really hard to do safely, if at all possible.
+  * Replaced some simple minded file operation security checks with more
+    decent ones.
+  * Don't use rename() to update mbox files and the archive, but write the
+    files directly.  This is more fragile, but required for correct mbox
+    locking, and also for mboxes in mail spool directories where we don't have
+    permission to create files.
+  * Fixed the test suite to deal with nanosecond file timestamps.
+  * Cleaned up the test suite, replacing a lot of duplicated code and avoiding
+    a lot of redundand testing.  This speeds up the test suite by a factor of
+    20 or so.
+  * mbox locking: completely rewritten.  Switched from flock to fcntl locking,
+    which is NFS-safe, and we now lock with fcntl first, then with a dotlock,
+    instead of the other way around.  (This is makes archivemail compatible
+    with Debian systems. ;)
+  * We now omit the dotlock if we don't have sufficient permissions to create
+    it in the mbox directory. Closes: #855269.
+  * Refactoring of the mbox classes; much of the code got rewritten.
+  * The archive now also gets locked while archivemail updates it.
+  * Various Python language fixes (for example don't use "0" and "1" as
+    boolean constants).
+  * Added a lot of test cases for maildir archiving to the test suite.
+    Maildir testing should now be roughly on par with mbox testing.
