Announcing the release of Session Token JWT v2, featuring a more compact and structured claim format.
Key changes in v2 include a revamped structure for organization-related claims, now nested under the o claim for improved clarity and reduced token size. Additionally, a new v claim explicitly identifies the token version.
As of today, April 14, 2025, version 1 of the session token format is deprecated. You can update to version 2 via the Updates page in your Clerk Dashboard.
For a detailed breakdown of all claims available in v2 and how they differ from v1, please refer to our Session Tokens documentation.
We strongly recommend using one of our SDKs that support API version 2025-04-10 to handle decoding reliably.
