+* Ready to make ChimeraX 1.12 release?
+ - Will release on Thursday June 11, 2026 if nothing new comes up.
+ - Discussed Windows error "An Application Control policy has blocked this file."  Happens in 1.11.1 and 1.12 release candidates.  Seems to happen only for a small number of users (23 reports in 3 months).  Greg has contacted user who reported it 4 days ago to see if it is reproducible.
+ - Eric as an alignment fix to make in release candidate.  Will be small, or if hard will postpone it to after release.
 
+* Python update to 3.14
+ - After release we will decide whether to update  Python 3.11 in ChimeraX.
+ - Python 3.14 has a getrefcount() change that requires a simple ChimeraX fix.
+ - Python 3.14 would need numpy 2 since numpy 1 not build for 3.14.
+
+* Generic Python API for toolshed bundles
+ - Can bundle developers with compiled code use the Python generic C API so they don't have to recompile for new ChimeraX versions that use newer Python?
+ - Greg believes that is already possible.
+ - Discussed whether ISOLDE could use this.  It links against ChimeraX atomic library so any change to that library API would prevent reusing ISOLDE in newer ChimeraX.  Eric says atomic API has seldom changed.
+
+* Ubuntu 26.04 builds
+ - Github Actions still does not have an Ubuntu 26.04 runner so we are not yet making a build of ChimeraX.
+ - Greg tested the ChimeraX 1.11 ubuntu 24 distribution on an ubuntu 26 VM and it started.
