DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Background Tasks Notable

Waiting on a backgrounded shell command now keeps a task alive, controlled by a remote setting defaulting on.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What

Work parked waiting on a backgrounded shell command is now treated as a live reason to keep the task alive, the same as waiting on a subagent, a monitor or a workflow. Killing a parked agent also cleans up shell tasks it left running. Controlled by the tengu_concurrent_shore remote setting, which defaults to on.

Details
  • Previously only agent:, monitor: and workflow: waiters counted; bash: waiters now do too.
  • Absent any server value the fallback is true, so this is live in this build.
