Release Notes

dani-garcia/vaultwarden (vaultwarden/server)

### [`v1.30.4`](https://togithub.com/dani-garcia/vaultwarden/releases/tag/1.30.4) [Compare Source](https://togithub.com/dani-garcia/vaultwarden/compare/1.30.3...1.30.4) ⚠️ 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](https://togithub.com/dani-garcia/vaultwarden/wiki/Proxy-examples). 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. #### What's Changed - Update crates to fix new builds by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4308](https://togithub.com/dani-garcia/vaultwarden/pull/4308) - Add Kubernetes environment detection by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4290](https://togithub.com/dani-garcia/vaultwarden/pull/4290) - Update GHA Workflows by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4309](https://togithub.com/dani-garcia/vaultwarden/pull/4309) - Update Rust, crates and web-vault by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4328](https://togithub.com/dani-garcia/vaultwarden/pull/4328) - Change the codegen-units for low resources by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4336](https://togithub.com/dani-garcia/vaultwarden/pull/4336) - Fix env templateto ensure compatibility with systemd's EnvironmentFile parsing by [@​seiuneko](https://togithub.com/seiuneko) in [https://github.com/dani-garcia/vaultwarden/pull/4315](https://togithub.com/dani-garcia/vaultwarden/pull/4315) - Update crates, GHA and a Python script by [@​BlackDex](https://togithub.com/BlackDex) in [https://github.com/dani-garcia/vaultwarden/pull/4357](https://togithub.com/dani-garcia/vaultwarden/pull/4357) #### New Contributors - [@​seiuneko](https://togithub.com/seiuneko) made their first contribution in [https://github.com/dani-garcia/vaultwarden/pull/4315](https://togithub.com/dani-garcia/vaultwarden/pull/4315) **Full Changelog**: https://github.com/dani-garcia/vaultwarden/compare/1.30.3...1.30.4
