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 Daemon

The background daemon can now retire a same-version instance; build is 2.1.248.

Feature flag
tengu_bg_binary_takeover Not enough to say

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

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The background daemon takeover now folds in an extra caller-supplied condition, so a transient daemon running the same version can be retired instead of being left in place. Build metadata moves to 2.1.248.

Details
  • Gated by tengu_bg_binary_takeover, which falls back to on.
