Object Storage Service:Version 1.91.8

Last Updated:Mar 19, 2026

ossfs 1.91.8 improves the mount failure experience and strengthens request stability for mounts using OSS V4 signatures.

Developer experience

Clearer error messages on mount failure

Previously, when a mount failed, the error output provided little actionable context, making it difficult to identify the root cause. This release adds descriptive prompt messages for failed mounts so you can diagnose issues without consulting external resources.

Accurate exit codes for mount failures

Exit codes for certain mount failure scenarios were imprecise. This release optimizes exit codes for these scenarios to improve error handling reliability.

Stability

Improved request stability for OSS V4 signature mounts

Mounts configured to use OSS V4 signatures can now handle requests more reliably.
