    Emacs 23 is the unicode2 branch.  It is being maintained in parallel
    at the moment and kept in reasonable shape, and some stuff has been
    merged into it that is not in Emacs 22 if I remember correctly.  When
    Emacs 22 is out and reasonably debugged, so that we won't need more
    22.x releases, the unicode branch will get merged to HEAD.  Then this
    will get merged into the multi-tty branch, and when this seems
    successful, the merge of multi-tty will go back into HEAD as well.

    Both branches are in reasonable shape AFAIK.  When most of the merges
    are through and it is clear whether we will release with multi-tty or
    not, adding new features starts making sense again.  Those should,
    however, be not too potentially destabilizing (like the lexical-let
    branch, I would guess, or Emacs-bidi).

    This is the idea of the next release after Emacs 22, and, considering
    the state of affairs in the branches, it should not take much more
    than half a year.  After all, the manual and code are in a good shape
    with our current release, and the Emacs 23 changes are somewhat

    Once unicode2 has become HEAD, there will be sense again in working
    seriously on the Bidi branch.  However, it is not clear when that will
    be fit for merging.

    I don't see what you hope to accomplish by pressing for destabilizing
    development right now with new features.

1. This is all good and interesting news. I was not aware of all that. I had
seen mention here of the unicode branch, the multi-tty branch, and bidi, but
I hadn't seen any such explanation. Thank you for the info.

2. I was joking, David. This release has been imminent or incipient for a
long time. There have been many harmless jokes about that.

3. I am not "pressing for destabilizing development right now with new
features".  And "I don't see what you hope to accomplish" by saying that I

Chill, please. I have not suggested adding _any_ new features to this
release, in fact. For almost 3 years now, I've only discussed possible
features to add _after_ the release (though some did get added to this

In the case of some major possible features I have in mind, I've not brought
them up at all, because I've been waiting for the release first (2-3 years).
I've raised only minor possible features, and always only for "after the

An exception to this minor-only discussion policy is that in Feb 2005 I
proposed some changes to Customize (for after the release, again) which it
turned out might not be minor, so that discussion was subsequently postponed
until after the release.

I'm interested in discussing additional features to be added, or changes to
be made, to Emacs _after_ the release, and I'm happy to learn that that will
likely be sooner than I expected. I'm also happy that the long anticipated
release will soon become a reality. Hallelujah!
