+# 8/22/2019
+
+### Attendees:
+
+* Rod Bogart
+* Joseph Goldstone
+* Larry Gritz
+* Cary Phillips
+* Nick Porcino
+* Christina Tempelaar-Lietz
+* Kimball Thurston
+
+### Agenda:
+
+* Release 2.4.0
+* Other items
+
+### 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.
