Hello folks,

alpha2 is out. It took a little longer and we ended up fixing some
hard to track down bugs while waiting to merge some more spkgs. The
highlight is likely the pynac.spkg - note that the actual library
integration code is not merged yet, but will be in 3.1.3 unless
something goes seriously wrong. The Sphinx toolchain and a couple
other spkgs are up next in 3.1.3.alpha3, hopefully out in 48 hours.
The release plan changed and instead for a release last weekend we are
now going for the this weekend since that way we can get all the
things we want into 3.1.3 for SD 10. Had we done a 3.1.3 quickly it
would have likely been really tight to get a 3.1.4 or a quick 3.2. out
the door in time for SD 10.

Sources and a binary for sage.math only are in the usual place at

http://sage.math.washington.edu/home/mabshoff/release-cycles-3.1.3/

Please test and report issues as usual.

Cheers,

Michael
