Is there a sync delay in the Vault documentation between the website and the git repo? - API Docs Update

From Vault 1.7.2 onwards, the AWS Secrets engine api READ endpoint (/aws/sts/:name) now supports the role_session_name as a new parameter as shown in the source code - vault/aws.mdx at main · hashicorp/vault · GitHub

But I do not see this documentation on - AWS - Secrets Engines - HTTP API | Vault by HashiCorp

Since this feature is already released officially on vault, I am a bit confused as to why its not on the official website.
