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))
