The merged version will use the Lucid code for zones.  These are _much_
more efficiently implemented and switching to them is a big win for a number
of Epoch features, including the redisplay model.

Selective display will be fully operational in the merged version.
The redisplay rewrite is in progress right now.  See the note posted
by Jamie Zawinski in alt.lucid-emacs.help for more information on the
merger and expected availability.

The merged version will have scroll bars.

As mentioned above, the zone implementation will be Lucid's extents.
These are already much more efficient than Epoch's zones.  You should
have no problems doing this.

A compatibility package will be available with the merged version, possibly
even before the merged version is released.

This all sounds really great (The lepoch 5.0 stuff) But there are a couple of
other things emacs19 has that I would like to see lepoch have:

Emacs19 has a built in hook to make sure that the titlebar of a frame is
always in sync with the active buffer in that frame - epoch could really use
that, as even with some of the enhancement code to do this, they still get out
of sync.

Along with the above, there should be a hook for allowing changing of a
screen's icon dynamically.  I wrote a bit of code for epoch that allows the
user to have a screens icon be customizable based on mode or title.  This code
works, but it occasionally gets out of sync for the same reasons as the
titlebars.

Lucid emacs already has this.  So, of course, the merged version will as
well.
