  - Builds have failed the last 3 days because update to PyQt 6.8 could not be fetched by Github Actions.
  - Zach said by email he will fix this.

* PySide6
  - Should next ChimeraX release use PySide6?
  - Would need to start testing now.
  - Grant proposals in next 6 months may reduce ChimeraX development time available.
  - Need to discuss further.  Who would take responsibility for PySide6 testing and fixes?

* Scenes

  - Piet will submit pull request to incorporate scenes API in bundle that will not be put in distribution yet.

* N453 door lock problem
  - Still can't use keypad to keep N453 door unlocked.
  - Greg submitted a ticket in December.  No word yet.
  - Greg will ask again.

* Anisotropic ellipsoid depiction
  - Eric having trouble saving sessions with AtomShapeDrawing class that Greg made for nucleotides.
  - Eric will make a ticket demonstrating problem.
  - Greg will investigate error saving sessions.

* pyKVFinder
  - KVFinder crashes often on Windows only.
  - Eric made standalone test case that only needs Python that crashes using ChimeraX --nogui.
  - Test does not crash if ChimeraX python executable used directly.
  - What about starting via chimerax executable is different than starting using python?
  - Eric will run more tests including making chimerax launcher code only call Py_Main() like python startup.
