Can I find versioned API documentation of hydra somewhere? https://www.ory.sh/docs/hydra/reference/api contains the latest API documentation, but I haven’t been able to figure out how to get documentation for, say, v1.11.x.

Hello @dry-sunset-53391 The API docs are generated from this file: https://github.com/ory/hydra/blob/master/spec/api.json So you can pick the version on github and use this for older Ory Hydra versions.
