--------------------------
= Discussion =

* Linux nightly build broken
  - It looks like the builds are actually working.
  - But the last commit date was April 27 instead of June 30 because the build tools extracted the wrong date from github and Zach had pushed a branch from April 27 on June 30 which was the most recent commit.
  - Greg will fix the build tools script to get the correct date.
  - This also explains why Elaine noted that ChimeraX reports the current daily build is from April 27 at start up.

* Toolshed disk quota error updating a bundle
  - Scooter fixed this increasing the toolshed disk quota from 1 byte to 100 GB.

* Mac dual display crash
  - Tom tested for half hour on 2 displays, could not produce crash.
  - Next let's try update to PyQt 6.5.1.  This crash started in Qt 6.4 and if we are lucky it has been fixed.

* mmCIF out of memory errors
  - Eric says we have not had reports of daily build giving mmCIF out of memory since Greg fixed a memory leak.
  - Greg tempted to make a 1.6.2 release to test this fix.
  - Eric thinks the fix is unlikely to be the problem since the errors are only Windows and the leak fixed was on all platforms.

* Chimera 1.17.2 release
  - Not yet made because of some Python 2/3 issue with bytes and strings in the script that makes the release.
  - Greg will fix it.
