I see that there was an agent update in the past few hours. If there are changes to agent behaviour, it would be useful to have it described on the Release Notes page. It also helps to understand how often the serene life of an agent is punctured by a global forced restart.
Generally, agents are restarted at every maintenance interval (the “scheduled maintenance for all servers” ones, vs the IDE/API ones).
There weren’t any agent-visible changes in this deploy (this was more infrastructure related), but yes we’ll endeavor to post notes for future deploys that add functionality.
