--------------------------
= Discussion =

* ChimeraX ideas milestone cleanup
  - We removed all completed items from the ideas milestone
  - We clarified remaining items.
  - Remains to 1) organize items into categories, 2) prioritize them, 3) move some to a ChimeraX 1.7 milestone.

* Python 3.11 in ChimeraX
  - Decided best to keep ChimeraX 1.6 at Python 3.9.
  - Switch to Python 3.11 right after the ChimeraX 1.6 release.
  - This gives more time for 3.11 to stabilize, it has only been out 3 months.
  - Also allows us to change to 3.11 at the start of a ChimeraX release cycle instead of rushing at the end.
  - Studied changes Zach made to build with 3.11: PyOpenGL and tinyarray and tables needed hand compiling.
  
* Python 3 generic C API
  - Greg says we may need to require Python 3.11 base to have Py_Buffer api, or maybe only 3.10 for unicode api.
  - This may not help in releasing a ChimeraX library for older Python (3.7, 3.8, 3.9), but an initial library release can just target 3.11.
