Update your Instance
It is critically important to keep your self-hosted Bitwarden instance up to date. Updates may include fixes that are important for the security of your Bitwarden instance, including patches to any vulnerabilities. Data stored in your Bitwarden vault, including passwords, should be considered critical data and therefore protected with up-to-date software.
Additionally, newer versions of client applications may not support older versions of your self-hosted instance.
If you're running a standard installation, update your Bitwarden instance using the same Bash (Linux or macOS) or Powershell (Windows) script (bitwarden.sh) used to install Bitwarden. Run the following sequence of commands:
Bash
./bitwarden.sh updateself
./bitwarden.sh update
