AI 3.8-15.1.2 Release Notes

Summary

New Features

  • Multipart upload support for S3 write cache lets S3 write-cache deployments handle full multipart upload workflows instead of falling back to slower paths.

  • Worker NIC-specific service binding allows RPC, data, REST, and web services to bind to different network interfaces in multi-NIC environments.

Major Enhancements

  • Job Service load operations monitoring improvements add better visibility into failures so operators can identify recurring problems more quickly.

Bug Fixes

  • S3 write cache fixes improve multipart upload correctness, list-result consistency, and persist-and-free behavior, including better handling for large directories and non-existent prefixes.

  • S3 API error handling fixes improve behavior when workers are offline and when clients list non-existent prefixes.

  • FDB metadata overwrite handling no longer uses a closed transaction during overwrite flows.

  • Cold-read redirect handling fixes a read error that could appear on redirect-enabled cold reads.

  • Job Service load operations memory usage is reduced for large loads that previously risked out-of-memory failures.
