# Changelog
## 2025-08-18 - 4.2.1 - fix(gzip)
Improve gzip streaming decompression, archive analysis and unpacking; add gzip tests
- Add a streaming DecompressGunzipTransform using fflate.Gunzip with proper _flush handling to support chunked gzip input and avoid buffering issues.
- Refactor ArchiveAnalyzer: introduce IAnalyzedResult, getAnalyzedStream(), and getDecompressionStream() to better detect mime types and wire appropriate decompression streams (gzip, zip, bzip2, tar).
- Use SmartRequest response streams converted via stream.Readable.fromWeb for URL sources in SmartArchive.getArchiveStream() to improve remote archive handling.
- Improve nested archive unpacking and SmartArchive export pipeline: more robust tar/zip handling, consistent SmartDuplex usage and backpressure handling.
- Enhance exportToFs: ensure directories, improved logging for relative paths, and safer write-stream wiring.
- Add comprehensive gzip-focused tests (test/test.gzip.ts) covering file extraction, stream extraction, header filename handling, large files, and a real-world tgz-from-URL extraction scenario.
## 2025-08-18 - 4.2.0 - feat(classes.smartarchive)
Support URL streams, recursive archive unpacking and filesystem export; improve ZIP/GZIP/BZIP2 robustness; CI and package metadata updates
