AI 3.8-15.1.17 Release Notes

Summary

AI 3.8-15.1.17 is a cumulative release focused on cache visibility, read consistency, Job Service load operations, and platform stability.

Cache Insight provides visibility into cached data and its relationship to the underlying storage. It supports parallel and targeted scans, incomplete-file filtering, and reporting of cache and source-size inconsistencies.

Read snapshot consistency can prevent a read from combining data from different versions of an object when the object is overwritten during the read. This protection covers supported local-cache, worker, and UFS read paths and is disabled by default.
Job Service load operations provide clearer progress reporting and more accurate skipped-byte accounting for long-running operations. Load recovery is also more reliable when worker state or backend metadata changes during execution.
Rename operations can use a direct path to the underlying storage, improving rename performance and behavior across supported UFS implementations. Clients using this option must have network access and credentials for the underlying storage.
S3 and UFS compatibility is improved through more reliable pagination, redirects, connection handling, retries, and object-version checks, including improved compatibility with Cloudflare R2.

Improved cache cleanup and recovery after objects are deleted, truncated, or overwritten, reducing stale data and helping segmented reads recover after a version mismatch.
Fixed S3 read and response handling in interrupted or failure scenarios.
Improved FUSE behavior for local-backed files and unlink operations.
Improved worker and coordinator availability during control-plane reconnects and write-cache initialization failures.

No breaking changes in this release.

No migration steps are required for this release.
