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

* Python 3.11 update
  - Greg suggested updating from Python 3.11.2 to 3.11.5 for various bug fixes.
  - Decided we should do that in the daily build once the ChimeraX 1.7 release is out.

* SciPy broken on macOS 11
  - Helix tubes use scipy which fails on macOS 11 with ARM CPU.
  - PyPi scipy requires macos 12
  - ChimeraX 1.5 and 1.6 also used macos 12 scipy, but an earlier 1.9 version while now we use 1.11 scipy.
  - Don't have a macOS 11 system to test on.

* ffmpeg flatpak error
  - Movie encoding fails in ChimeraX 1.7rc flatpak distribution with image files not found message.
  - Greg reproduced this on his flatpak ChimeraX.
  - Flatpak comes with ffmpeg 5.0.3.
  - Not clear if this is a problem with ffmpeg accessing files in /tmp or if the flatpak ffmpeg was compiled without %d file name support.
  - Greg will investigate.
  - Tom tried ffmpeg 5.0.1 static build on Ubuntu and it worked.

* Windows trailing space in directory name
  - Eric fixed Chimera bug where it creates a user-specified directory on Windows with a trailing space.
  - Trailing spaces not supported on Windows for files and directories.

* ChimeraX 1.7 release
  - Eric suggest we may be ready for release in 1 to 2 weeks.
