Discussion:

• Outstanding problem with deep reads: it has been fixed.
• We should be in a good place for v3.1.3, there aren’t any outstanding issues.
• Cary: I’ve been cherry picking commits into a branch and submitting as a PR to merge into RB-3.1, because that gives an easy-to-view list of the merged commits. 
• Larry: In my projects I merge to the branch right after merging to master, but either is fine.
• Why does OpenEXR do chroma subsampling?
• Rod: Florian had an obsession about 422 and chroma subsampling, he put it in early. He wasn’t happy with how chroma subsampling was done in the early years at ILM.
• Larry: It’s different from any other image format, except ones that are specifically video.
• EXRs are linear, but video isn’t.
• Kimball: It’s an arbitrary number: subsampling set to 17.
• Rod: B44 compression was also from Florian.
• Kimball: That’s ok, it’s what ProRes does.
• Rod: Whether there is subsampling is orthogonal to whether it’s linear or not.
• Joseph: MacPorts
• Feels like trying to understand the language of a vanished civilization
• All the C++ stuff builds and installs
• The python modules don’t install. There’s a problem with the venvs
• Nick: That’s why there’s been movement towards conda, away from venvs
• Joseph: I’m working with an old codebase that’s built around macports, but a new codebase that uses conan. I’ll keep struggling with it.
• Cary: I now have an account on a Fedora project ILM machine, can investigate the s390x test failure.
• Kimball: We ported Manuka to the Power series. There’s something weird, like char is not the same signed-ness as the default. Unsigned by default?
• Cary: The suggestion is that it’s an endian issue, since the x390x is big-endian.
• Christina: A windows build issue with static linking of zlib
