+## [2.2.1] - 2026-03-25
+
+### Added
+
+- **Manifest-aware module detection** — parses `Package.swift`, `Cargo.toml`, `build.gradle.kts`, `package.json`, `pubspec.yaml`, `go.mod`, and `pyproject.toml` to auto-discover targets and source paths instead of just scanning directories.
+- **Export granularity control** — `"exportLevel": "type"` in `specsync.json` limits exports to top-level type declarations (class/struct/enum/protocol) instead of listing every member.
+- **Configurable module definitions** — `"modules"` section in `specsync.json` lets you define module groupings with explicit file lists.
+- **Language-specific spec templates** — `generate` and `--fix` produce Swift, Rust, Kotlin/Java, Go, and Python templates with appropriate section headers and table columns.
+- **AI context boundary awareness** — generation prompt instructs the provider to only document symbols from the module's own files, not imported dependencies.
+
+### Fixed
+
+- **Test file detection** — expanded Swift patterns (Spec, Mock, Stub, Fake), added Kotlin/Java/C# patterns, and detect well-known test directories (`Tests/`, `__tests__/`, `spec/`, `mocks/`).
+- **Check command no longer hangs on empty specs** — returns clean JSON/exit 0 when `--fix` is used with no spec files.
+- **Exit code 101 panic → friendly error** — wraps main in `catch_unwind`, converts panics to actionable error messages with bug report link.
