Release Notes

dani-garcia/vaultwarden (vaultwarden/server)

v1.30.3

Compare Source

This is a minor release to fix some issues with push notification device registration and docker healthcheck.

⚠️ Note: The WebSockets service for live sync has been integrated in the main HTTP server, which means simpler proxy setups that don't require a separate rule to redirect WS traffic to port 3012. Please check the updated examples in the wiki. It's recommended to migrate to this new setup as using the old server on port 3012 is deprecated, won't receive new features and will be removed in the next release.
