On-site in N453.

= Agenda =

* ChimeraX
  - Make ChimeraX 1.4 release candidate now?
  - Are Windows open dialog crashes fixed?
  - 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 =

* Drop CentOS 7 for ChimeraX 1.4?
  - SBGrid has half ChimeraX users (220/440) on CentOS 7 in last 6 months
  - Greg tried compiling Qt 6 on CentOS 7, core worked, web engine failed with gcc 10
  - Greg will try gcc 9 to compile Qt 6.
  - If compile fails we make ChimeraX 1.3 the last CentOS 7 release

* How can Tristan compile ISOLDE for old Linux?
  - Tristan updated his CentOS 7 desktop to Ubuntu 20.
  - Uses CentOS 7 virtual machine to compile ISOLDE for toolshed.
  - Greg suggests using singularity image would be simpler.
  - Discussed providing no-gui CentOS 7 ChimeraX without Qt for plugin developers to build against.
  - Greg suggested providing Docker image of ChimeraX CentOS 7 build environment.
  - Discussion with Zach of continuous integration / cloud builds of ChimeraX being used by plugin developers who need to compile code.

* Windows open dialog crashes
  - Got one Qt 6.2 windows open dialog crash, might be rare
  - Will continue look for this crash until about a week before release, then remove Windows crash reporting since it has not been useful (Eric and TomG concur).

= Action Items =
  - Update ChimeraX to Qt 6.3.0.  Greg
  - Present github continuous integration tutorial.  Zach
  - Remove pkg-config prereq if it is not being used for builds. Tom
