 # tsbundle Hints and Findings
 
+## Recent Updates (2025-11-23)
+
+- Migrated from @push.rocks/smartfile v11 to @push.rocks/smartfs v1.1.0
+- All filesystem operations now use async smartfs API
+- Removed @push.rocks/tapbundle (now imported from @git.zone/tstest/tapbundle)
+- All bundlers (esbuild, rolldown, rspack) updated to latest versions
+- Removed deprecated rolldown experimental.enableComposingJsPlugins option
+
 ## Bundler Architecture
+
 - tsbundle uses a child process architecture where each bundler runs in a separate process
 - Configuration is passed via environment variables as JSON (IEnvTransportOptions)
 - The main class `TsBundle` spawns child processes using `smartspawn.ThreadSimple`
 
 ## Bundler Implementations
-- **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

+- **esbuild** (default): Fully implemented, production ready, 3.9K minified
+- **rolldown**: Implemented and working (beta v1.0.0-beta.51), produces smallest bundles (1.0K minified)
+- **rspack**: Implemented and working (v1.6.4), webpack-compatible API, 6.3K minified
 - **rollup**: Removed (was never implemented)
 - **parcel**: Removed (was never implemented)
 
 ## Adding New Bundlers

 To add a new bundler, you need:

 1. Update `ICliOptions` interface to include the bundler name
 2. Add case in `getBundlerPath()` switch statement

 ## Rolldown Specific Notes

 - 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

 - Rspack v1.3.15 - stable and production ready
 - Uses webpack-compatible API (callback-based)
 - Built-in SWC loader for TypeScript transpilation

 ## CLI Usage
+
 - Default bundler: `tsbundle` (uses esbuild)
 - Specify bundler: `tsbundle --bundler=rolldown` or `tsbundle --bundler=rspack`
 - Production mode: `tsbundle --production`
 - Combined: `tsbundle --bundler=rolldown --production`
 
 ## Known Issues

 - esbuild recently had splitting and tree-shaking disabled due to issues
