- `yggdrasil` was upgraded to a new major release with breaking changes, see [upstream changelog](https://github.com/yggdrasil-network/yggdrasil-go/releases/tag/v0.4.0).

- `icingaweb2` was upgraded to a new release which requires a manual database upgrade, see [upstream changelog](https://github.com/Icinga/icingaweb2/releases/tag/v2.9.0).

## Other Notable Changes {#sec-release-21.11-notable-changes}

- The setting [`services.openssh.logLevel`](options.html#opt-services.openssh.logLevel) `"VERBOSE"` `"INFO"`. This brings NixOS in line with upstream and other Linux distributions, and reduces log spam on servers due to bruteforcing botnets.

  However, if [`services.fail2ban.enable`](options.html#opt-services.fail2ban.enable) is `true`, the `fail2ban` will override the verbosity to `"VERBOSE"`, so that `fail2ban` can observe the failed login attempts from the SSH logs.

- Sway: The terminal emulator `rxvt-unicode` is no longer installed by default via `programs.sway.extraPackages`. The current default configuration uses `alacritty` (and soon `foot`) so this is only an issue when using a customized configuration and not installing `rxvt-unicode` explicitly.

- The `claws-mail` package now references the new GTK+ 3 release branch, major version 4. To use the GTK+ 2 releases, one can install the `claws-mail-gtk2` package.

- The wordpress module provides a new interface which allows to use different webservers with the new option [`services.wordpress.webserver`](options.html#opt-services.wordpress.webserver).  Currently `httpd` and `nginx` are supported. The definitions of wordpress sites should now be set in [`services.wordpress.sites`](options.html#opt-services.wordpress.sites).

  Sites definitions that use the old interface are automatically migrated in the new option. This backward compatibility will be removed in 22.05.
