+Version 1.2.1:
+       By default, unmounting a read-write mounted WIM with 'imagex unmount
+       --commit' will now change the WIM in-place without needing to write the
+       entire WIM again.  Use 'imagex unmount --commit --rebuild' to get the
+       old behavior.
+
+       'imagex unmount' no longer has a hard-coded limit of 10 minutes to wait
+       for a response from the daemon servicing the mounted WIM.  Instead,
+       every second 'imagex unmount' will check if the daemon is still alive,
+       and keep waiting if so, otherwise terminate with an error.
+
+       'imagex unmount --commit' on a read-write mounted WIM will now print
+       progress information regarding the writing of new or modified streams
+       the WIM, just like when capturing or appending a WIM.
+
+       A small change has been made to XPRESS compression and it should improve
+       the compression ratio slightly.
+
+       Microsoft has managed to introduce even more bugs into their software,
+       and now the WIMs for Windows 8 have incorrect (too low) reference counts
+       for some streams.  This is unsafe because such streams can be removed
+       when they are in actuality still referenced in the WIM (perhaps by a
+       different image).  wimlib will now work around this problem by fixing
+       the stream reference counts.  This is only done when wimlib_delete_image() is
+       called ('imagex delete') or when wimlib_mount_image() is called with
+       WIMLIB_MOUNT_FLAG_READWRITE ('imagex mountrw').  Please note that this
+       requires reading the metadata for all images in the WIM, so this will
+       make these operations noticably slower on WIMs with multiple images.
