What's New in v3.1.7
🔐 MCP OAuth 2.1 Authentication (#1169)
Full OAuth 2.1 support for MCP servers — RFC 7591 (Dynamic Client Registration), RFC 9728 (Protected Resource Metadata), RFC 8414 (Authorization Server Discovery), RFC 8707 (Resource Indicators). Includes secure token storage, step-up authorization, and CLI commands (opencode mcp oauth login/logout/status).
🔧 LSP Client Migration to vscode-jsonrpc (#1095)
Replaced custom JSON-RPC implementation with vscode-jsonrpc library for improved protocol stability. Bun↔Node stream bridges for compatibility. ~60 line net reduction.
