quick summary notes

Cylc-8.3.0

• aim for March, this is pretty urgent
• triage: drop all non-essential issues back to 8.4 or 8.3.x
• cylc set is essential, but we can push cylc remove and skip-mode back
• the remaining optional outputs work is less critical, since we took expire out of the mix

Cylc-8.2.5

• UK team still think this is worth releasing, before 8.3.0 gets out
• (NIWA side: I don't mind either way, no pressing 8.2.4 bugs are affecting us that I'm aware of)
• OS to review 8.2.x and 8.2.5 milestones tomorrow

Migration:

• high support workload at the moment, making it hard to get development time

Open questions (link above)

• we all need to put a bit of time into considering those, they're piling up

Multi-user gscan

• this is viewed as a requirement at BOM, due to a significant number of production role accounts
• in principle the UI can manage multiple subscriptions to multiple (user-specific) UI Servers, and users would appear at the top level of the gscan hierarchy, but to date we've had to concentrate on efficiency and stability of the single-user subscription
• to do multi-user properly there's quite a lot to consider, e.g. what determines which other users you can see, load on the UI for many users, etc.
  -- it may be an option for BOM to do this via a local UI extension (even a separate "gscan view" perhaps); but note that development and code review resources are currently very limited, so it might have to be maintained separately for a good while with no guarantee to be merged as-is

AWS Batch

• some MO work going is going on now with Cylc on AWS
• NIWA has a dev 1-day per week for a while, considering cloud platform support in Cylc (just starting)
