New Azure Keyvault API

Hey guys
So according to the Microsoft Email
"Azure Key Vault API version 2026-02-01—releasing in February 2026—introduces an important security update: Azure role-based access control (RBAC) will be the default access control model for all newly created vaults. Existing key vaults will continue using their current access control model. Azure portal behavior will remain unchanged."
There should be a new API Version for Azure Keyvault

I Wanted to change the API we use in our Bicep files to this new 2026-02-01 Version
But it seems its not released yet even though it should be according to microsoft?
Do you know something about delays with the new API?
