# Server & Client Versioning
Currently Bitwarden clients and server use a `yyyy.mm.r` convention, indicating, for example, that `202250` is the base release (`.0`) of May (`.5.`) 2022 (`2022.`). If subsequent hotfixes are released, for example, they would be `2022年5月1日`, `2022年5月2日`, and so on.
Initial monthly releases (those ending in `.0`) are shared across all clients and server, but clients and server may deviate as some get hotfixes (`.1`s, `.2`s, and so on) while others don't.
This hasn't always been the case, though. Prior to May 2022, clients and server each had different versioning systems. If you're using a client or server with a version `1.xx.x` or `2.xx.x`, you're using an old version.> [!NOTE] Deprecating Versions> When Bitwarden drops support of a version, the entire release and all previous versions will also no longer be supported.
## Self-hosted server version
To find your self-hosted server's version, log in to the [System Administrator Portal](https://bitwarden.com/help/system-administrator-portal/). **Server**and **Web**versions will be listed on the dashboard. If the **Installed**versions don't match the **Latest** versions, [update your server](https://bitwarden.com/help/updating-on-premise/):

You can also check the `bitwarden.sh`/`bitwarden.ps1` file to see which versions are installed. Running `updateself` will update these if newer versions are available, and running` update` will update Bitwarden containers based on what's listed in the `.sh`/`.ps1` file.
