What probably matters to youSection of the release
What
CLAUDE_CODE_USE_GATEWAY is now on the allowlist of environment variables copied into processes Claude Code spawns, alongside the other provider switches such as CLAUDE_CODE_USE_BEDROCK and CLAUDE_CODE_USE_MANTLE, so a session routed through an enterprise gateway hands that routing down instead of dropping it.
Details
Unconditional for anyone who has the variable set.
