Approve 2021/12/14 minutes.	Scot Breitenfeld	post last meeting’s minutes to CGNS webpage. Approved.
high-level editing tools for the documentation page	Marc Poinot Christopher Rumsey	Help needed to divide the remaining tasks: https://github.com/CGNS/cgns.github.io/projects/1 The documentation goes into the source using Doxygen. This work uses the “doxygen” branch. Examples are given for cg_open and cg_version. The aliases used for repeated variable descriptions are in src/doxygen/doxygen.config. Need volunteers to help with translating the remaining APIs to Doxygen. A link to the new website is provided on the main cgns web page: https://cgns.github.io/cgns-modern.github.io/index.html All the MLL APIs have Doxygen entries, the cgio APIs need to be done next. An automatic generation of the website through github action is done.

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 NEW (June 2021) We need to add Intel OneAPI compilers to the list of supported compilers (note: OneAPI C/C++ compiler is very different to existing legacy one) Bug list: CGNS-176 - Getting issue details... STATUS A priority of bugs to fix in next release #1 CGNS-135 - Getting issue details... STATUS 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 important to have parallel working #4 CGNS-166 - Getting issue details...
