What probably matters to youSection of the release

What

Steer mode can now be chosen based on the model in use rather than only env, client data and growthbook.

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

What has happened since
Flag reading moved The flag server now returns "default" for tengu_thistle_grebe, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
