Discussion

• Windows builds are running, but tests are failing.

• Windows test failure appears to be a “device timeout” in IlmImfTest, not sure how to proceed. Might be an Azure job setting?

• Release version should be named v2.4.0-beta.1

• What to do with PR #502? Alignment issue, but it’s only in the test suite. Probably ok.

• Need to update release notes with recent commits. Kimball suggests the GitHub project git-chglog.

• Still need a security expert. Kimball suggests Dan Hutchinson at Foundry, who was a security expert in the past.

• Florian is enthusiastic about contributing new test images. Need to decide what we need to show off. Florian suggests carefully calibrated images to show what a properly exposed image is.

• Rod noted that ACES has reference images.

• Another application for these images: calibration. Need reference for monitor calibration.

• Joseph: an image that can help answer the question, “Does this look right?” image. Joseph described a past project that involved $100 at Safeway: Pepto Bismol pink, etc. Everyone knows what those colors are.

• Also need images for a performance suite.

• Also need relevant survey of metadata.

• We need a document that says what stuff is called, conventions.

• Outstanding issue: PR #531, the DreamWorks Lossy Compression license. Is the change sufficience? It's a dual license: pick which license the user wants to use.

• Joseph: Half as a separate library? Support in GCC and Clang for 16-bit float? Would there be a performance gain to use standard? Yes. But Half does very specific rounding. With float16 you can do different rounding. Could use operators to make Half and float16 look the same.
