What probably matters to youSection of the release
What
The check for Harbor cross-session messaging was rewritten. Setting CLAUDE_CODE_HARBOR_KITE now forces it on regardless of platform. Windows, which previously always returned false, is allowed through when the separate tengu_harbor_kite_win gate is on. The general gate is consulted last. Both gates fall back to off in this build, so unless the environment variable is set, whether it runs is decided by remote config.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_harbor_kite_winOff by default, switched on for this account
The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.
