SST released opencode v1.14.30 (April 29, 2026). Support for Mistral Medium 3.5 with reasoning mode was added, Azure response handling improved, and issues with sessions in the Desktop app and editor context across multiple directories were fixed. The April release cadence has been tight: v1.14.27 introduced a configurable default shell, v1.14.25 added Roslyn LSP for C#/Razor, and v1.14.21 brought improved compaction for long conversations.

Why it matters

Opencode is one of the leading open-source competitors to Claude Code and Codex, multi-provider by architecture. Support for Mistral Medium 3.5 with reasoning expands the model selection for offline/edge scenarios.
