Release Notes

1.2.0

August 21, 2025

Dynamic Provisioning: Added support for automatic S3 bucket creation during PersistentVolumeClaim provisioning referencing a storage class.
Controller Service: Controller service is now deployed by default (previously experimental) to support dynamic provisioning.
Helm Chart Updates:
Added global s3.region and s3.endpointUrl values that apply to both node and controller services.
Legacy node.s3EndpointUrl and node.s3Region values are still supported and take precedence for backward compatibility.
Added new controller section in Helm chart values.yaml with improved credential provider and RBAC permissions.
Added configurable images.provisioner section in values.yaml for controller sidecar image configuration.

Product Name Update: Renamed from "Scality S3 CSI Driver" to "Scality CSI Driver for S3" per AWS legal requirements.
Enhanced Documentation: Added comprehensive architecture documentation including:
System overview and deployment architecture diagrams
Static provisioning flow documentation with detailed workflows
S3 credentials management architecture and best practices

SystemD D-Bus Reliability: Fixed D-Bus connection recreation for improved SystemD mount reliability and error handling.
Documentation Improvements: Remove base64 mention from credentials in kubernetes secrets as the CSI driver does not use it.

Flexible credential strategies: driver‑level credentials and per‑volume credentials managed with Kubernetes Secrets.
Optimized for Scality RING with advanced configuration options.
Documentation site: https://scality.github.io/mountpoint-s3-csi-driver/.

Static provisioning only; dynamic provisioning is planned for a future release.
Optimized for sequential writes, random writes and file modifications follow S3 semantics.
Single‑writer semantics per object ensure data consistency.
Symbolic and hard links are not supported due to S3 limitations.
Empty directories require at least one object in order to persist in S3.
SELinux enforcing mode on the Kubernetes host is not yet supported.
