# Versions  28.4.0 & 27.12.0

For compatibility information of each P4V version with Autodesk Vault versions, visit the [System Requirements](https://help.besmart.software/p4v/system-requirements#compatibility-matrix) page.

## Known Issues

* Some user accounts may experience random web license disconnecting. That may happen mostly after midnight. Manual reconnecting/restart of the licensing client is necessary.
* A standalone licensing method may experience issues if a shared licensing folder is used.
* The API key licensing method may experience issues if a shared licensing folder is used.
* Inventor Model states are not supported.

We are working on fixes, and in the meantime, we recommend you test the behavior before deployment to the production environment.
