What
Claude Code asks a feature-flag service (GrowthBook) which features are switched on for a session, and sends it some attributes describing that session. This release adds one:
- A new attribute,
atisPin, is sent whenever a storedatisvalue is present. If the value looks likev1.<pin>.x.y.z(five dot-separated parts), only the second part is sent; otherwise the whole string is sent. atisPinis added to the list of attribute keys and tocacheKeyAttributes, so cached flag values are kept separately for each pin.- A new
refreshAtisPin()compares the current pin with the one the flag client has and fetches flags again when they differ. It runs after the start-up data (bootstrap) has been fetched, and only when the new switchtengu_serene_teacuppasses.
tengu_serene_teacup falls back to on when the server sends no value. Nothing has been read about this switch yet.
Why
For anyone who has an atis value, which features a session gets can now depend on that pin, and flag values are refreshed when the pin changes.
tengu_serene_teacup Not enough to sayNothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

What the atis pin is and what it affects for a user are not known.
