+* 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.
