IMPROVEMENTS:

    * ``bzr log`` now shows dotted-decimal revision numbers for all
    revisions, rather than just showing a decimal revision number for
    revisions on the mainline. These revision numbers are not yet
    accepted as input into bzr commands such as log, diff etc. (Robert
    Collins)

    * revisions can now be specified using dotted-decimal revision
    numbers.  For instance, ``bzr diff -r 1.2.1..1.2.3. (Robert
    Collins)
