 ## [Unreleased]
 
+## [0.3.0] - 2025-12-24
+
+### Added
+- **Trait-based ecosystem architecture** — Unified handling for all package ecosystems
+  - `Ecosystem` trait with parser, registry, and formatter
+  - `EcosystemRegistry` for dynamic ecosystem lookup by URI
+  - `LockfileProvider` trait for lock file parsing
+  - Simplified document lifecycle with generic handlers
+
+### Changed
+- **Performance optimizations** — Significant latency improvements
+  - Parallel registry fetching with `futures::join_all` (97% faster document open)
+  - O(N log K) cache eviction algorithm with min-heap (90% faster eviction)
+  - Parse-once pattern for version sorting (50% faster parsing)
+  - String formatting optimization with `write!()` macro
+  - Early lock release pattern with `get_document_clone()`
+
+### Fixed
+- npm: Remove extra quotes in code action version replacements (#29)

+## Performance
+
+deps-lsp is optimized for responsiveness:
+
+| Operation | Latency | Notes |
+|-----------|---------|-------|
+| Document open (50 deps) | ~150ms | Parallel registry fetching |
+| Inlay hints | <100ms | Cached version lookups |
+| Hover | <50ms | Pre-fetched metadata |
+| Code actions | <50ms | No network calls |

+> [!TIP]
+> Lock file support provides instant resolved versions without network requests.
