v2.0.0 – 2025-11-22

Added

• Expanded MCP tool suite – the server now registers navigation (go_to_definition, find_references), diagnostics (check_diagnostics), insights (get_hover_info, get_completion), refactor helpers (format_document, rename_symbol, list_code_actions), testing (run_go_test, analyze_coverage), workspace commands (search_workspace_symbols, run_go_mod_tidy, run_govulncheck, module_graph), and notification plumbing, all backed by new end-to-end tests under pkg/tools.
• Prompt catalog – summarize_diagnostics and refactor_plan prompts expose curated messaging for Cursor/Claude via the MCP prompt API.
• CI + tooling enforcement – make verify now runs gofmt/goimports checks, golangci-lint, go vet, go test, and go mod tidy validation, and .github/workflows/ci.yml runs the suite on every push/PR. scripts/tidy-check.sh ensures dependency files stay clean.
• Documentation overhaul – Quick Start instructions, tool invocation table, prompt usage guide, and troubleshooting tips were added to README.md and docs/usage.md for Cursor, Claude, Copilot, and MCP Inspector integrations.

Changed

• CLI entrypoint – cmd/mcp-gopls validates workspace paths, log settings, RPC/shutdown timeouts, and custom gopls binaries before startup, handles SIGINT/SIGTERM, and reports shutdown status.
• Go requirements – bumped to Go 1.25 with github.com/mark3labs/mcp-go v0.43.0 plus the new JSON/protocol dependencies used by the extended LSP surface.
• Progress notifications – long-running tools stream logs with namespaced tokens, eliminating “unknown token” errors in Cursor and surfacing clearer status updates.
• Govulncheck automation – run_govulncheck automatically falls back to go run golang.org/x/vuln/cmd/govulncheck@latest when the binary is missing, with explicit progress messaging.

Fixed

• Coverage fallback – analyze_coverage always returns aggregate results even when per-function parsing fails, so release artifacts never miss coverage numbers.
• Transport robustness – the JSON-RPC transport reads exactly one message per call and closes cleanly on pipe errors; the gopls client now discovers GOROOT via go env to avoid stale runtime paths.
