 # Changelog
 
+## 2025-06-19 - 2.4.0 - feat(bundler)
+Introduce rspack bundler support and update multi-bundler workflow
+
+- Added full support for rspack with its own implementation in ts/mod_rspack
+- Updated package.json: new dependency on @rspack/core and revised description
+- Refactored bundler types and switch statement to remove deprecated rollup and parcel options
+- Modified test suite to include tests for esbuild, rolldown, and rspack with bundle size comparisons
+- Adjusted output configuration for esbuild and rolldown for dynamic naming and inline dynamic imports
+
 ## 2025-06-19 - 2.3.0 - feat(bundler)
 Integrate rolldown bundler support and update bundler selection logic

 ## Bundler Implementations
-- **esbuild** (default): Fully implemented, production ready
-- **rolldown**: Implemented and working (beta), produces smaller bundles than esbuild
-- **rollup**: Empty module directory exists but not implemented
-- **parcel**: Empty module directory exists but not implemented
+- **esbuild** (default): Fully implemented, production ready, 2.2K minified
+- **rolldown**: Implemented and working (beta), produces smallest bundles (1.5K minified)
+- **rspack**: Implemented and working, webpack-compatible API, 6.1K minified
+- **rollup**: Removed (was never implemented)
+- **parcel**: Removed (was never implemented)

@@ -24,12 +25,22 @@ To add a new bundler, you need:
 - Rolldown is in beta (v1.0.0-beta.18) but working well
 - API: Use `rolldown()` function directly, not `rolldown.rolldown()`
 - Output options go in the `write()` method, not the initial config
+- Uses `dir` and `entryFileNames` instead of `file` for output (handles dynamic imports)
+- Includes `inlineDynamicImports: true` to avoid chunk splitting issues
 - Produces smaller minified bundles than esbuild (1.5K vs 2.2K in tests)
 - Supports TypeScript via `resolve.tsconfigFilename`
 
+## Rspack Specific Notes
+- Rspack v1.3.15 - stable and production ready
+- Uses webpack-compatible API (callback-based)
+- Built-in SWC loader for TypeScript transpilation
+- Produces larger bundles than esbuild/rolldown due to webpack runtime overhead
+- Best choice if you need webpack compatibility or advanced features
+- Supports ES modules output via `experiments.outputModule: true`
+
 ## CLI Usage
-- Default bundler: `tsbundle`
-- Specify bundler: `tsbundle --bundler=rolldown`
+- Default bundler: `tsbundle` (uses esbuild)
+- Specify bundler: `tsbundle --bundler=rolldown` or `tsbundle --bundler=rspack`
 - Production mode: `tsbundle --production`
 - Combined: `tsbundle --bundler=rolldown --production`
