Summary

OpenCode shipped v1.14.26 on April 26, 2026 with reliability-focused fixes for permission rule ordering and OpenRouter DeepSeek reasoning output handling.

What changed

OpenCode released v1.14.26 with core fixes for config parsing, DeepSeek reasoning output handling through OpenRouter, and a versioned User-Agent header.

Why it matters

AI coding tools are increasingly judged on how well they survive provider-specific edge cases in real workflows. This patch matters because it hardens both permission semantics and reasoning-model interoperability instead of adding a flashy feature that still leaves multi-provider sessions brittle.

Evidence excerpt

The v1.14.26 release notes say OpenCode fixed config parsing to preserve permission rule order and fixed OpenRouter DeepSeek reasoning output handling.
