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

* Broken Linux builds
  - Greg fixed them today.
  - Problem was with fakeroot support using singularity.

* Tristan can't log in to Trac
  - Zach notes he cannot log in using Chrome.
  - Greg and Tom confirm Trac login from Chrome fails, Firefox works.
  - Greg thinks it might be a Kerberos configuration issue.  Says Scooter would need to look at that.
  - Greg sent Tristan email warning that Chrome login does not work.
  - If Trac login fails for Tristan in Firefox then possibly authentication for web-only accounts is not enabled in Apache.  Greg says that would be a Scooter issue.

* Update ChimeraX from Python 3.9 to 3.11
  - Decided we are ready to merge Zach's Python 3.11 branch for daily builds, after asking Tristan if it is ok with him.
  - Tom will ask Tristan today so we can hopefully go to 3.11 tomorrow.
  - Zach fixed Wayland Python 3.11 problem caused by updated PyOpenGL 3.1.6 trying to automatically use EGL.  Zach changed code to explicitly ask for x11 PyOpenGL since EGL has some problems.
  - Zach showed Python 3.11 changes.  Several places in C++ use ssize_t which he had to change to Py_ssize_t since Windows does not have the posix ssize_t.

* ChimeraX library distribution
  - Zach asks if making a macOS PyPi distribution initially is an ok plan (instead of Linux).  All agreed that is fine.

--------------------------
= Action Items =
  - Present github continuous integration tutorial.  Zach
