 # Changelog
 
+## 2025-11-25 - 4.2.4 - fix(plugins)
+Migrate filesystem usage to Node fs/fsPromises and upgrade smartfile to v13; add listFileTree helper and update tests
+
+- Bumped dependency @push.rocks/smartfile to ^13.0.0 and removed unused dependency `through`
+- Replaced usages of smartfile.fs and smartfile.fsStream with Node native fs and fs/promises (createReadStream/createWriteStream, mkdir({recursive:true}), stat, readFile)
+- Added plugins.listFileTree helper (recursive directory lister) and used it in TarTools.packDirectory and tests
+- Updated SmartArchive.exportToFs to use plugins.fs and plugins.fsPromises for directory creation and file writes
+- Updated TarTools to use plugins.fs.createReadStream and plugins.fsPromises.stat when packing directories
+- Converted/updated tests to a Node/Deno-friendly test file (test.node+deno.ts) and switched test helpers to use fsPromises
+- Added readme.hints.md with migration notes for Smartfile v13 and architecture/dependency notes
+
+## 2025-11-25 - 4.2.3 - fix(build)
+Upgrade dev tooling: bump @git.zone/tsbuild, @git.zone/tsrun and @git.zone/tstest versions
+
+- Bump @git.zone/tsbuild from ^2.6.6 to ^3.1.0
+- Bump @git.zone/tsrun from ^1.3.3 to ^2.0.0
+- Bump @git.zone/tstest from ^2.3.4 to ^3.1.3
+
 ## 2025-08-18 - 4.2.2 - fix(smartarchive)

+# Smartarchive Development Hints
+
+## Dependency Upgrades (2025-01-25)
+
+### Completed Upgrades
+- **@git.zone/tsbuild**: ^2.6.6 → ^3.1.0
+- **@git.zone/tsrun**: ^1.3.3 → ^2.0.0
+- **@git.zone/tstest**: ^2.3.4 → ^3.1.3
+- **@push.rocks/smartfile**: ^11.2.7 → ^13.0.0
+
+### Migration Notes
+
+#### Smartfile v13 Migration
+Smartfile v13 removed filesystem operations (`fs`, `memory`, `fsStream` namespaces). These were replaced with Node.js native `fs` and `fs/promises`:
+
+**Replacements made:**
+- `smartfile.fs.ensureDir(path)` → `fsPromises.mkdir(path, { recursive: true })`
+- `smartfile.fs.stat(path)` → `fsPromises.stat(path)`
+- `smartfile.fs.toReadStream(path)` → `fs.createReadStream(path)`
+- `smartfile.fs.toStringSync(path)` → `fsPromises.readFile(path, 'utf8')`
+- `smartfile.fs.listFileTree(dir, pattern)` → custom `listFileTree()` helper
+- `smartfile.fsStream.createReadStream(path)` → `fs.createReadStream(path)`
+- `smartfile.fsStream.createWriteStream(path)` → `fs.createWriteStream(path)`
+- `smartfile.memory.toFs(content, path)` → `fsPromises.writeFile(path, content)`
+
+**Still using from smartfile v13:**
+- `SmartFile` class (in-memory file representation)
+- `StreamFile` class (streaming file handling)
+
+### Removed Dependencies
+- `through@2.3.8` - was unused in the codebase
+
+## Architecture Notes
+
+- Uses `fflate` for ZIP/GZIP compression (pure JS, works in browser)
+- Uses `tar-stream` for TAR archive handling
+- Uses `file-type` for MIME type detection
+- Custom BZIP2 implementation in `ts/bzip2/` directory

 `SmartArchive` accepts archives from three sources:

-2. **File** - Load archives from the local filesystem
+|--------|--------|----------|
-3. **Stream** - Process archives from any Node.js stream

+console.log(`Extracted ${extractedFiles.length} files in memory`);
+```
+
+### Nested archive handling (e.g., .tar.gz)
+
+The library automatically handles nested compression. A `.tar.gz` file is:
+1. First decompressed from gzip
+2. Then unpacked from tar
+
+This happens transparently:
+
+```typescript
+import { SmartArchive } from '@push.rocks/smartarchive';
+
+// Automatically handles gzip → tar extraction chain
+const tgzArchive = await SmartArchive.fromArchiveFile('./package.tar.gz');
+await tgzArchive.exportToFs('./extracted');
 ```

 ## Performance Tips 🏎️
 
-1. **Use streaming for large files** - Avoid loading entire archives into memory
+1. **Use streaming for large files** – Avoid loading entire archives into memory with `exportToStreamOfStreamFiles()`
-2. **Process files in parallel** - Utilize stream operations for concurrent processing
+2. **Provide byte lengths when known** – When adding streams to TAR, provide `byteLength` for better performance
-3. **Choose the right format** - TAR.GZ for Unix systems, ZIP for cross-platform compatibility
+3. **Process files as they stream** – Don't collect all files into an array unless necessary
-4. **Enable compression wisely** - Balance between file size and CPU usage
