Steve, Assume no one has done anything yet, but to keep on the agenda.
Should start in December.
* upcoming release planning (1.5 weeks to go, -1 weeks to feature
freeze, -1 weeks to have everything reviewed) [RH]
Roland, weeks to go, freeze was last week, no more changes. Name is as
below.
Nov 30th is the release, Monday after Thanksgiving. Gallery examples,
two are
finished and uploaded, BNS and scalar wave example. Work by Miguel and
Steve.
Miguel, has uploaded everything. Steve, trying to get the Mathematica
setup right.
Needs to have a couple of different packages installed and X windows.
Have not
had luck with LSU running X11 back to his machine. Will try to get
around any
firewalls, or go into the office. Tried downloading to laptop on
Windows partition
will not run SimulationTools executable from Windows. Steve wants a
Python script
to make the plots. Done in the next week. Bill, has run Poisson and
looks fine.
Made the Visit plot.

** release testsuite
[http://einsteintoolkit.org/testsuite_results/index.php status]
Roland, Not a lot of news. Did re-run on supported clusters, fixed the
two punctures
failure, it required running with higher resolution. Fixed a bug in
Carpet's flipped in one
direction. Affected the PETSc test on Queen Bee. Golub cluster has the
largest number
of failures, is using Intel and Slurm. Stampede does better than
Golub. Maybe Intel
compiler is defaulting to more agressive compilation.
Roland, drafted a release announcement and Maintainers should have a
copy. Please
read and make comments. Two persons are new: Jonah Miller (doc Kranc)
and Matthew Ely
(Llama support). If there are others please tell Roland so he can get
permissions and their
names in the Zenodo and citation.

Open bugs of severity major or worse]
Roland, Tkt #2479 has existed for some time and .. You can depend on
parameters
of Thorns that are not active, which it should not. Saw in some of the
testsuite tests.
Thorn needed to compile even if not used in calculation. Not a crucial bug.

* any other business
Steve, we are not meeting next week, Thanksgiving in the US. Next
meeting Thursday
December 3rd---Roland is chair and Miguel is minute taker.
Zach, LaTeX parser update with Ken. Working on parsing the BSSN
equations as exist in
Baumgarte's Spherical NR and Baikal. Mostly functionally where we need
to be. Working
on the documentation. Also a nice Unit Testing infrastructure---cannot
rely on Sympy
simplification being very deterministic, so created a novel method
involving hashing
symbols into high precision numbers. Using Sympy's multiprecision
math. Used to
evaluate that expressions are equivalent. Roland, Probing with floating
point numbers,
what about exact math, fractions, etc. Zach, good idea.
