AI Summary

Version 1.22.1 addresses critical reliability issues introduced in the previous version, specifically a race condition causing I/O errors on truncated files and a bug causing insufficient cache space retention.

Key Highlights

  • Fixes a race condition that caused I/O errors on subsequent reads after closing truncated files.
  • Corrects a validation bug where Mountpoint preserved less than 5% of available space due to incorrect cache limits.
  • Includes binaries for x86_64 and arm64 architectures.

Full Release Notes

* Fix a race condition where concurrent operations after closing a truncated file could result in I/O errors on subsequent reads. The issue was introduced in v1.22.0. ([#1781](https://github.com/awslabs/mountpoint-s3/pull/1781))
* Fix incorrect validation of default data cache limit which would cause Mountpoint to preserve less than 5% of available space. ([#1779](https://github.com/awslabs/mountpoint-s3/pull/1779))
