Marnik:
  * Started working on updating `aiida-pseudo` and `aiida-quantumespresso` plugins to `aiida-core==2.0.0a1`. Having a crack at writing a little plugin migration script (See [#5335](https://github.com/aiidateam/aiida-core/issues/5335)) which I'd add to `verdi devel migrate-plugin`.

Francisco
  * Re-adapted the PR on the lock mechanism ([5331](https://github.com/aiidateam/aiida-core/pull/5331)) to include the movement on the maintain features to the new structure.

Giovanni

  * Testing today various DBs migrations
  * Want later to test also submission, but I think Eiger is still down, so I might need to defer testing the submission to tomorrow
  * Plans for 2.0 adaptation of plugins (most important: aiida-quantumespresso, aiida-pseudo)?

Jason:
  * Try to check if the `2.0.0a1` fix https://github.com/aiidateam/aiida-core/issues/4876 but eiger is under maintainance so maybe can not test it today. Will migrate aiida-sssp-workflow, it can every time reproduce this 'maximum recursion depth' issue.
  * What is the final decision about `TemplateCodeInfo` PR https://github.com/aiidateam/aiida-core/pull/5350 ?
