Tools official 1 src. ~1 min

OpenCode v1.17.0 (June 10, 2026) adds faster file search via fff (Rust/SIMD-accelerated fuzzy finder), Cohere North model integration, Claude Fable 5 reasoning support, MCP tool improvements (abort signals, correct pagination), Java Maven workspace resolution, session recovery from provider context-overflow errors, WSL-backed Desktop on Windows, and improved sessions and servers UI.

Why it matters

fff-backed file search is a meaningful DX improvement for large monorepos where file search latency bottlenecks agentic tasks. Cohere North integration expands provider options for teams preferring enterprise-grade open-weight models.

Importance: 2/5

Notable open-source coding agent update; fff integration and Cohere North addition are substantive additions.
