Ruby SDK 17.2.1

Released on Aug 13, 2026

Breaking changes

KSM-1193: create_secret now raises an error if the application configuration has no owner public key. Every other SDK already requires this key for record creation. This change makes Ruby consistent with the other SDKs. The SDK sets this key only during binding. An already-bound configuration cannot get this key later. Re-bind with a fresh one-time token, or set the KSM_APPOWNERPUBLICKEY environment variable if you use the read-only EnvironmentStorage.

Security

• KSM-1193: Resolved an encryption issue with create_secret commands, affected by versions 17.0.3, 17.0.4, 17.1.0, and 17.2.0. This fix affects only records created after the SDK upgrade. To fix any existing records, the records must be deleted and re-created.
