* ChimeraX
  - Qt 6 problems.
  - Windows open dialog crashes.
  - Make ChimeraX 1.4 roadmap.
  - Upgrade Trac to mysql for better reliability.
  - Is Windows crash reporting ever useful?  Should we disable it?  Will Qt 6.2 fix spurious file dialog errors?
  - Should we remove pywin32 (20 MBytes) and wmi used only to report computer model in bug reporter on Windows? Ticket #5528
  - Task termination at app quit
  - Rename ChimeraX.exe on Windows?
  - Should we go to Python 3.10 in 1.5?

* Chimera
  - Switch Chimera daily builds from Windows 7 to Windows 10
 
* Action items

= Discussion =

* Qt 6
  - Greg suggests we us PyQt6 licensed wheels with PyQt6-Qt6 PyPi bundle that provides the Qt libraries.
  - Currently we instead bundle Qt6 with PyQt6 ourselves into a single wheel.
  - Would be simpler if we did not have to bundle.
  - Greg will try to make the change today or next week.
  - Qt 6.2.4 has come out and will be easy to put in daily builds with this change.
  - Zach says 4 ChimeraX Qt tickets are waiting on a new Qt version to fix them.
  - Qt 6.3 is supposed to release April 12

* Qt 6 for CentOS 7
  - Tests with singularity show Qt 6 won't work with CentOS 7 because newer system calls used by Qt 6.
  - This will also prevent FlatPack and Docker images from working.
  - Plan is now to make ChimeraX 1.3 (Qt 5) the last CentOS 7 release.

* VirtualGL
  - Commercial license holder reported ChimeraX not working with VirtualGL 3.0
  - Greg says this is because it is trying to use an EGL context, and bug report should be made to VirtualGL.
  - Possibly older VirtualGL 2.5 or 2.6 will work, and bug reporter will try that.

* Linux Wayland replacing X11
  - Greg says some most recent Linux distros are trying to make Wayland the default instead of X11 which requires using EGL for our OpenGL graphics.
  - Qt 6 is supposed to support EGL.
  - ChimeraX uses PyOpenGL and may have EGL support.
  - We may need to look into EGL for ChimeraX 1.5 or 1.6.

* ChimeraX 1.4
  - Goal is to release in May.
  - Original release date was April 1, but we are trying for May 1.
  - All features should be in within 2 weeks for a release candidate.
  - Still hoping Python 3.9.11 stops the 5 bug reports of day on Windows Open dialog crashes -- so far none reported in 3.9.11 but only out a week.

* Fire alarm
  - Building fire alarm ended meeting early.
