5.1.21	WEKA native multi-tenancy: Added the default internal NAT subnet, 198.18.0.0/16, used for network spaces. >> Container state and status fields: New topic. Clarified how to interpret state and status in container and process output from the CLI and REST API. >>
	NeuralMesh Observe: New topic. Monitor cluster health, validate performance, and troubleshoot your WEKA estate from one SaaS observability interface. >>

Configure S3 OIDC authentication so users and applications can authenticate with your identity provider and receive temporary S3 credentials without static access keys. >> S3: Added support for URL-formatted object keys, such as https://company.com/id, to improve compatibility with AWS S3 applications. >> S3: Removed the default filesystem from installation. Removed the key and secret parameters. KMS: Added OpenBao Vault 2.5.1 or later as a supported KMS. References to HashiCorp Vault also apply to OpenBao Vault. CIDR policies: Added squash mode.
