What's New
Patch release bun-v1.4.4 ships no detailed changelog beyond install instructions and a jump from 8 to 39 contributors.
Improvements
- Contributor count rose from 8 in v1.4.3 to 39 in v1.4.4, suggesting a broader set of changes than the notes describe.
- Windows install script URL moved from bun.sh to bun.com, aligning the install domain with the documentation site.
Upgrade Notes
Both releases publish only install/upgrade boilerplate, so the actual code delta must be read on Bun's blog before upgrading. The version bump is a patch (1.4.3 to 1.4.4) with no breaking changes announced, so `bun upgrade` should be safe. If you pin the Windows PowerShell installer URL, update it to the bun.com domain.
