GH keeps rolling out more features for Actions well after the initial release, adding things like Organization wide Secrets. Overall I'm quite happy with the progress.
I've run about ten thousand builds now and find the biggest issue the mysterious cancelling of jobs (especially on Win/Macos host), crashing of jobs across the board during GH outages, and the intermittent long pauses (e.g. 15min) between jobs in a multi-job build when nothing appears to happen (scheduling delays). GH could have more clarity on the status board, since I'll see many jobs fail, and check the status page to see everything is green. :/
