The 5.9.11 release process is finished.  (Ironically, that coincided
almost perfectly with when the University of Victoria finally fixed my
incoming mail issues!)

The svn commit freeze that was in effect is now thawed, and I look
forward to your commits for our next release (5.10.0) of PLplot which
will be our first stable release since 5.8.0 was released 6 (!) years
ago.

My initial plan (always subject to change depending on your needs) is
to make this release cycle short (a month or so) and mostly devoted to
fixing bugs.  I hope, for example, we can clear up most of the bugs
that we discovered in the closing stages of the 5.9.11 release cycle,
but which we did not have time to fix before the 5.9.11 release.
(Just search our mailing list over the last two weeks for the phrases
"post" and "release" which occurred together in quite a few
discussions.)

Tcl/Tk/Itcl/Itk/Iwidgets issues are a special case for this release
cycle.  Most of the burden of fixing those will fall on Arjen because
he is the only active PLplot developer with expertise in those
languages, and I do not want to restrict what he does to just bug
fixing. Instead, I strongly encourage him to deliver more than just
bug fixes during this release cycle.  In my opinion it has been too
long since our Tcl, etc., bindings and examples got a lot of attention
from an expert.  There are bound to be some fairly large things he
wants to change, and I believe such changes are okay for a "stable"
release so long as we thoroughly test Arjen's changes on the platforms
accessible to us, and our release notes clearly state the relatively
large changes that have gone on.

During this release cycle I plan to work almost exclusively on
epa_build which will also be a special case with more than just bug
fixing in this stable release cycle.  I think this is OK since
epa_build is so immature in any case.

Are there any other special (more than just bug-fixing) development
cases out there for this stable release cycle?  If so, please let us
know about them now if you think they are appropriate. But if you
think your PLplot development is not suitable for a stable release
cycle, I would still encourage you not to wait, but instead develop
now on a branch that can be merged in later during our next series of
development releases.

Best wishes for the Christmas season and our shiny new release cycle!
