= Discussion =

* Windows installer signing
 - Greg says some chance that signing will work in tonights builds.

* Release candidate
 - Branch not yet made and no release candidates up.

* !PyPi ChimeraX library
 - A user asked if ChimeraX !PyPi library is available for Windows.
 - Currently only version for Mac and old ChimeraX 1.8.
 - User did not respond to Tom's reply asking if they knew about using --nogui option to run scripts.

* Generic Python C API
 - Greg wants to have ChimeraX use generic Python C API for the 1.12 release.
 - This will help third party extension writers who use compiled code make one binary release that will still work in future ChimeraX versions that use newer Python 3.x.

* TCIA database
 - Eric asks if Zach has responded to developer who described TCIA database reorganization.  Not yet.

* Zach priorities
 - Animation GUI
 - Move medical imaging to bundle.
 - MCP AI agent interface

* Mailing list spam
 - Getting spam advertising (gambling, online casinos, real estate) on ChimeraX mailing list possibly by AI bots which are capable of registering a new user, confirming email, then posting.
 - Eric and Greg added some fields to block bots from using ChimeraX mailing list sign-up cgi-bin.

* Tristan
 - Tom will notify Tristan of upcoming release.
 - Tristan says RCSB removing ligand-expo which provides CCD templates for codes containing underscore characters for protonation states is not needed.  He includes those files in ISOLDE.
