Agenda items

Actions from last meeting

We discussed the actions from last time. One action on Ali was rolled over since he was not available this time.

Review use cases - #36

Discussion around things like stressing gc, native memory etc. Agreed those are also important and should go into another document titled something like .key runtime attributes. . Michael took action to submit PR for initial version of that doc.

We walked through the PR with the uses cases and there were no suggested changes so will plan to go ahead and land the PR.

Open issues review

We reviewed and discussed the open issues. Uttam mentioned a few things they are working on and will be raising new issues to cover that work.

Actions for next meeting

  • Ali to look at issue in hydrogen mentioned by Gareth
  • Michael to submit initial version of PR for key runtime attributes
  • Uttam to open issues for the activities he mentioned

Next meeting

Michael to set next meeting for 3-4 weeks from now.
