A poll was taken after the meeting, A majority of the committee decided on option 2:

15min | prioritization, review and attribution of JIRA bugs/issues | Platform proposals Windows is under-tested. Suggest Test C and Fortran serial and parallel on Windows 10 x64 as a bare minimum Do we test both 32bit (legacy) and 64bit API? It's a minor point, but it would a good idea to add 32bit to at least one Linux and Windows Bug list:
A priority of bugs to fix in next release #1
Crucial to Ansys. Although most HPC is Linux, project set-up often was done on Windows and import/export/sharing of mesh/solution done on Windows, while most runs performed on Linux clusters #2
#3
- important to have parallel working #4
#5
#6
Conflicting bugs - are we supporting configure or not? Very confusing to end-users Overall comments from Ansys
https://cgnsorg.atlassian.net/browse/CGNS-184 During the meeting, this was marked as having the highest priority for ansys
Overall comments from NUMECA I generally agree with the comments from ANSYS / Tony Garrett. I will second a few points based on NUMECA's needs: Highest priority bugs:
We have disabled parallel CGNS in our release packages until CGNS 176 and CGNS 109 are fixed, it became a problem for our support engineers. I agree with the comments on configure vs CMAKE. Our internal library maintenance system is built on configure, and it would be nice to maintain support if possible.

5min | high-level editing tools for the documentation page | Raw html is not an ideal format to maintain documentation, the latex version seemed easier. It was mentioned to maybe go back to using latex, but the latex version is now out of date compared to the html version. Some committee members were uncertain whether the latex format was the right way to go when compared to other documentation methods (Markdown, Readthedocs, etc…). Either way, it will involve some effort to move from the html versions.
