Summary

Version 1.18.23 fixes third-party provider routing through Cloudflare AI Gateway and converts dotted Anthropic model IDs to the dashed form expected by Anthropic. It also fixes parent-session headers for session-aware providers and GitHub authentication using immutable OIDC subject tokens.

Why it matters

The release improves interoperability for developers using OpenCode as a multi-provider agent client. The fixes address concrete provider, authentication and session failures that can disrupt automated engineering workflows.
