branch-2.5


From: Joel E. Denny
Subject: branch-2.5
Date: Mon, 6 Apr 2009 17:54:41 -0400 (EDT)

Akim and I have agreed that there are several new features that should be 
released in 2.5 before the current development on master will likely have 
time to stabilize enough.  Alex's value/location naming is one feature we 
think may be ready in time for 2.5.  My minimal LR and canonical LR 
implementation is another.  Also, there are some simple changes on master 
that appear to be stable enough now.

I just pushed a branch-2.5, created from the HEAD of branch-2.4.2.  I then 
cherry picked commits from master as I thought was appropriate.  See the 
list below.  For the moment, I've skipped the Java and C++ changes.  I'd 
appreciate it if their authors would suggest which ones are stable enough 
for 2.5.  I haven't yet added the semicolon warnings from Di-an that I 
asked about a couple days ago.  For that, I'll wait a little longer in 
case anyone wants to respond.  If there's no answer, I'll add it as I 
believe that was our agreement.  Of course, if I've included anything from 
master that isn't stable or if I've overlooked anything that is ready, we 
can adjust.

I'm new to development on multiple branches.  I figure there's no need to 
email old patches all over again.  Thus, below, I've listed only the git 
log entries for the patches I cherry picked from master.  In some cases, 
the patches didn't apply cleanly, so cherry-pick -x left off the "(cherry 
picked from commit xxx)" comment, and I had to make superficial changes or 
trim parts out entirely.  I tried to always update the git log and 
ChangeLog entries to reflect my changes.  However, I committed with the 
original author's info to give him credit.  The committer info that git 
records is hopefully enough to assign blame to me for any mistakes.  Is 
this approach satisfactory?  Is there any customary practice I'm not 
following here?
