     27* Qt 6
     28  - Greg suggests we us PyQt6 licensed wheels with PyQt6-Qt6 PyPi bundle that provides the Qt libraries.
     29  - Currently we instead bundle Qt6 with PyQt6 ourselves into a single wheel.
     30  - Would be simpler if we did not have to bundle.
     31  - Greg will try to make the change today or next week.
     32  - Qt 6.2.4 has come out and will be easy to put in daily builds with this change.
     33  - Zach says 4 ChimeraX Qt tickets are waiting on a new Qt version to fix them.
     34  - Qt 6.3 is supposed to release April 12
     35
     36* Qt 6 for CentOS 7
     37  - Tests with singularity show Qt 6 won't work with CentOS 7 because newer system calls used by Qt 6.
     38  - This will also prevent FlatPack and Docker images from working.
     39  - Plan is now to make ChimeraX 1.3 (Qt 5) the last CentOS 7 release.
     40
     41* VirtualGL
     42  - Commercial license holder reported ChimeraX not working with VirtualGL 3.0
     43  - Greg says this is because it is trying to use an EGL context, and bug report should be made to VirtualGL.
     44  - Possibly older VirtualGL 2.5 or 2.6 will work, and bug reporter will try that.
     45
     46* Linux Wayland replacing X11
     47  - 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.
     48  - Qt 6 is supposed to support EGL.
     49  - ChimeraX uses PyOpenGL and may have EGL support.
     50  - We may need to look into EGL for ChimeraX 1.5 or 1.6.
     51
     52* ChimeraX 1.4
     53  - Goal is to release in May.
     54  - Original release date was April 1, but we are trying for May 1.
     55  - All features should be in within 2 weeks for a release candidate.
     56  - 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.
     57
     58* Fire alarm
     59  - Building fire alarm ended meeting early.
