+* Nightly builds failed due to plato Qt file permissions.
+  - Greg has fixed Qt 6.9 file permissions on plato so nightly builds should start working again.
+
+* New atomspec parser
+  - Eric got new C++ atomspec parser all working, but it is no faster (0.3% faster) then Grako.
+  - Turned out all the time was spent in Python finding the atoms/bonds/residues and that code did not change.
+  - Eric proposes merging the new parser branch into develop in case we need to get rid of Grako in the future, but not using it for now.
+  - The new parser uses C++17 and our current ChimeraX compilers don't meet that standard.  If we need to update compilers, better to just turn off build of new parser.
+
+* Distributing chutil.a static library on Mac for ISOLDE
+  - Tristan does not have chutil.a from chimerax core that he needs to compile clipper on Mac.
+  - We have not distributed that in the Mac universal build because the make_univeral.py script does not know how to merge ARM and Intel static libraries.
+  - Let's ask Tristan how he built clipper for ChimeraX 1.9 since it has the same issue.
+  - Discussed that atomic library links to chutil and may expose symbols for chutil.
+  - Discussed making chutil a dynamic library.  That would raise problems with finding it during runtime linking.
+
+* Switch from PyQt to PySide
+  - We will get nightly builds working with Qt 6.9.1 this week before trying to switch to Qt 6.9.1.
+  - Tom suggests making tech preview of PySide instead of daily build so we can test without getting a lot of bug reports from users.
