= Discussion =

* Deprecate mmtf reader
 - Should we remove mmtf from ChimeraX?
 - Yes, announce on the mailing list and remove from daily build.
 - Greg says PDB stopped supplying mmtf binary files for new entries in 2024.
 - PDB has a newer binary mmcif format.

* Github pypi package security warnings
 - 6 security warnings about PyPi packages: lxml, filelock, requests, pygments, messagepack
 - Greg will update these

* Amber 26 update
 - Eric working on updating from Amber 20 to Amber 26 (6 year jump).
 - Trying build on Windows, not yet in daily build, currently causing test suite failure.  Fix has been made.

* Updating PyPi packages
 - Looked at outdated PyPi packages using prereqs/pips/Makefile app-outdated target.  Shows about 60 packages.
 - We should consider which are important to keep up to date.
 - Discussed keeping certifi up to date.

* PySide
 - Zach may try switching PyQt to PySide in daily build when Qt 6.11.2 comes out.
 - We reverted from Qt 6.11.1 to Qt 6.10.2 due to a main window resizing bug when floating tools present.
 - If we want to use PySide instead of PyQt in next December ChimeraX release need to be using it in daily builds no later than August to give enough time for testing.
