* ReadInterpolate code inclusion https://bitbucket.org/einsteintoolkit/tickets/issues/2416 [RH]
Reviewed positively by Yosef Z., should be voted next week, Roland is still working on removing one redundant parameter.
* Con2Prim framework update: https://bitbucket.org/einsteintoolkit/tickets/issues/2414 [RH] * Work in progress, currently debugging, group will report once science setup is working (it is a better Con2Prim method for GRHydro and IllinoisGRMHD) It will not be included in the coming release but probably in the next.
• Zach’s group is also working on a Con2Prim for Hybrid EOS like the one HARM code uses.
* NRPyPN will be reviewed by Peter D. probably will not be ready for the coming release but for the next.
* Status of new LaTeX interpreter for NRPy+ [ZE]
Zach gave a detailed tour of LaTeX interpreterhttps://nbviewer.jupyter.org/github/zachetienne/nrpytutorial/blob/feature-parser/Tutorial-LaTeX_SymPy_Conversion.ipynb mainly developed by Ken Sible. The user injects pure LaTeX math expressions and gets SymPy expressions that could be used with NRPy to generate highly efficient C code. Tensor support, index rising, multiple expression, operators support (interprets covariant derivatives). NRPy notation but user can take control and override NRPy quantity definitions. Will be validated with BSSN expressions.
Next step GPU support.
* Release manager for November ET release [RH]
-The manager’s tasks include time line, find persons for the gallery examples, find open tickets critical to the release.
-Steve suggest to break the Release manager tasks into pieces to reduce the manager’s work load.
-Maria, Zach and Yosef volunteered to help with the release tasks.
* Tickets ———
* LEAN code is looking for a reviewer.
* Red hat is extending support for python2 to 2024 - NRPy and NRPyPN will support it too.
* simfactory needs to be ported to python 3 but might be good to wait until the majority of clusters use python3 as default. Might be good idea to have support for the two version.

BBH galery example: changed the colors and the mass factors. Will make one line dashed. This will be used on the website.
Vote to include/exclude ReadInterpolate thorn. Reads in Cactus 3D output files and interpolates. No objections were raised.
SPEC benchmark needs to not be forgotten (last brought up in March). Erik was involved last time.
Hosting cactuscode.org on github. Roland made a lot of progress in updating it. Only a few outstanding issues remain.
Update on the LaTeX interpreter. Greatly enhancing the robustness of indexed expressions. How to distinguish between an upper index 2 and a 2nd power. Use double curly braces for an exponent. Use double curly braces for an exponent. Steve suggests a \pow{} macro. Currently, double curly braces signify exponent. Working on handling diacriticals. Expect to show off more next week.
Unanswered questions: Atul and Federico
No new bugs. Fixing smalling things.
#2385 incorrect looping boundary macro issue.
Please look at tickets ready for review.
Managed to spin up 184 cores for the tutorial on Friday, so if anyone needs to do that again, we can.
@Steve & @Roland: Need to write down tasks for the release coordinator.
