What probably matters to youSection of the release
What
The gateway's Postgres store configuration has a new setting, store.readiness_grace_seconds. /readyz is the address a hosting platform checks to decide whether a copy of the gateway is ready to take traffic. While Postgres, the database the gateway stores its data in, is not answering, /readyz now keeps reporting ready for up to this many seconds before it reports not ready.
store.readiness_grace_seconds takes a whole number from 0 to 3600.
It can be written as a number or as a string of digits.
It defaults to 0, which keeps the previous behaviour of reporting not ready straight away.
The gateway also writes new log lines that explain the setting.
Why
During a brief database failover, a hosting platform that sees the gateway report not ready may pull or replace its running copies. A short grace period keeps them in place while the database comes back.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added sinceA small documentation edit on Claude apps gateway spend limits touched a line naming store.readiness_grace_seconds after this was published.Fail-open only helps while your load balancer or orchestrator still routes traffic to the gateway.
