+## 1.0.0
+
+### Breaking Changes
+
+- Removed deprecated simple API aliases (`getFormat`, `getTags`, `getProperties`, `setTags`, `getCoverArt`, `setCoverArt`)
+- Minimum Node.js requirement: v22+ with `--experimental-wasm-exnref` flag
+
+### Features
+
+- **Fluent `edit()` API** for tag modifications with method chaining
+- **`Symbol.dispose` support** across Full and Workers APIs for `using` pattern
+- **RAII memory management** with `WasmAlloc` and `WasmArena` for leak-free Wasm operations
+- **Runtime-agnostic WASI host** supporting Deno, Node.js, and Bun via `FileSystemProvider` DI
+- **Realigned API naming**: `readTags`, `readProperties`, `readFormat`, `readCoverArt`, `applyCoverArt`, `readPictureMetadata`
+- **Batch metadata API**: `readMetadataBatch` for efficient multi-file processing with cover art and dynamics data
+- **Wasmtime sidecar** for native filesystem access on server runtimes
+- **Folder scanning API** for recursive directory metadata extraction
+
+### Bug Fixes
+
+- Fixed memory cleanup in `open()` error paths and `isValidAudioFile()`
+- Fixed progress tracking and type-safe error tags in folder-api
+- Hardened worker pool with proper try-finally cleanup
+- Fixed negative seek position handling in WASI adapter
+
+### Internal
