📄 View Raw Release Notes (Original Developer Log)

## Highlights - Slower drives or slower networks that hit DriveMaxTimeouts but asynchronously wake up the connection with new data can potentially trigger an incorrect buffer to be shared among concurrent WRITE goroutines. The final data buffer might not be the same that was intended to be written to the disk, causing cross-pollution of buffers among objects. This release fixes this problem, which has affected releases since - RELEASE.2023-08-04T17-40-21Z, which added drive timeouts on the READERs (rarely triggered since drives don't usually hang for READERs) - This problem was partially addressed in RELEASE.2023-11-11T08-14-41Z unknowingly, However, it ended up manifesting itself now with WRITERs since the WRITERs used same deadline READERs for the network stream in this release. - We haven't seen reports of this from community users yet; we found this internally during our tests in a customer deployment. All users are advised to upgrade to the latest release. ## What's Changed * re-use the same local drive used by remote-peer by @harshavardhana in https://github.com/minio/minio/pull/18645 * Label the notification target metrics by their target IDs by @Praveenrajmani in https://github.com/minio/minio/pull/18633 * update console UI to v0.43.0 release by @harshavardhana in https://github.com/minio/minio/pull/18653 * Fix CreateFile shared buffer corruption. by @klauspost in https://github.com/minio/minio/pull/18652 **Full Changelog**: https://github.com/minio/minio/compare/RELEASE.2023-12-13T23-28-55Z...RELEASE.2023-12-14T18-51-57Z
