+PH/06 A failure to get a lock for a hints database would erroneously always say
+ "Failed to get write lock", even when it was really a read lock.
+
+PH/07 The appendfile transport was creating MBX lock files with a fixed mode
+ of 0600. This has been changed to use the value of the lockfile_mode
+ option (which defaults to 0600).
+
+PH/08 Applied small patch from the Sieve maintainer.
+
+PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
+ folder from quota calculations, a direct delivery into this folder messed
+ up the contents of the maildirsize file. This was because the regex was
+ used only to exclude .Trash (or whatever) when the size of the mailbox
+ was calculated. There was no check that a delivery was happening into an
+ excluded directory. This bug has been fixed by ignoring all quota
+ processing for deliveries into excluded directories.
+
+PH/10 Added the maildirfolder_create_regex option to appendfile.
