* Talk on ChimeraX web services implementation by Zach
  - Zach explained new REST web services method for replacing SOAP/Opal.
  - Discussed how input parameters for job are passed.
  - Discussed how job return values are packaged (e.g. multiple files).
  - Discussed how job progress reports might work.
  - Scooter would like existing ChimeraX web services using this long before ChimeraX 1.4 release (May 2022?)
  - BLAST is using it.
  - Next is Modeller, Zach will get it done by 2 weeks from now and present.
  - Then multiple sequence alignment (clustal) added using Opal by Eric 2 weeks ago.
  - Eric will try to implement REST seq alignment after Zach converts Modeller.
  - Another service to convert is AlphaFold BLAT search.
  - And a more complex case to try later is AlphaFold prediction on Wynton.

* Qt 6 ChimeraX on download page
  - Greg hopes to havel Qt 6 tech preview on download page tomorrow.
  - Tom has been using it 4 weeks without problems.
  - Tom wants it in circulation to see if many Qt 5 crashes are fixed, or workarounds needed.
  - Greg notes new Fedora Linux versions work with Qt 6 but not Qt 5.
  - Greg has setup tech preview support on download page for future uses.
    * Runs script at start of build to patch files or do other setup.
    * Flag indicates whether to add it to download page.
    * Can edit download page to explain what is new in a particular tech preview.

* Redesign of client Task / Job classes
  - Zach thinking Tasks should inherit from dict.
  - Discussion of drawbacks of inheriting from dict
    * Allows too much access to dict methods.
    * Can confuse session saving seeing an instance as a basic type.
