**[Bun](https://daily.dev/sources/bun)** · 5 min read · 63 upvotes · 2 comments

## Summary

Bun v1.3.3 fixes 95 issues and introduces several new features. Key additions include CompressionStream and DecompressionStream APIs with support for gzip, deflate, brotli, and zstd formats. Standalone executables now support flags to disable automatic .env and bunfig.toml loading. The test runner gains retry and repeats options for handling flaky tests. A new --no-env-file flag allows disabling automatic environment file loading. SQLite has been upgraded to version 3.51.0, and the runtime now uses Zig 0.15.2. The release includes numerous bug fixes across the bundler, package installer, Windows support, Node.js compatibility, Web APIs, networking, YAML parsing, and TypeScript definitions.
