Claude Code v2.1.186 22 Jun 2026

AWS Credential Refresh in Login Wizard

When an existing Claude Platform on AWS session is detected, a new "Claude Platform on AWS · refresh credentials" option appears in the 3rd-party platform setup screen.

Details

Invokes the awsAuthRefresh command configured in your settings.
On success, shows "AWS credentials refreshed." and lets you continue.
On failure, shows a clear error message and suggests running the command manually in a separate terminal.
Only appears when an active AWS session context is available.

Evidence

New aws_refresh / aws_refresh_running / aws_refresh_done states in the login UI (search for "Claude Platform on AWS ·" and "AWS credentials refreshed.")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
