This update is all about keeping OpenCode running smoothly with the latest artificial intelligence technologies. If you use OpenCode to connect to Microsoft's Azure cloud or use OpenAI's newer services, this release makes sure your connections are stable, fast, and free of weird glitches caused by leftover code from older systems.
Improvements
- Ready for GPT-5.6: We updated our system to fully support GPT-5.6 on Azure AI (Microsoft's cloud platform). This means you can now reliably use this newer, smarter AI model in your projects.
Fixes
- Cleaning up old AI code: We removed an outdated temporary fix (called a "workaround") that was originally written for Codex, an older AI model. This old code was accidentally clashing with and blocking newer OpenAI "Luna Responses Lite" requests. Removing it fixes those connection issues.
Breaking changes
No breaking changes in this release.
