and advises all users to use `paperless-ng` instead.
Users can use the `services.paperless-ng` module as a replacement while noting the following incompatibilities:
-`services.paperless.ocrLanguages` has no replacement. Users should migrate to [`services.paperless-ng.extraConfig`](options.html#opt-services.paperless-ng.extraConfig) instead:
- The `erigon` ethereum node has moved it's database location in `2021-08-03`, users upgrading must manually move their chaindata (see [release notes](https://github.com/ledgerwatch/erigon/releases/tag/v2021.08.03)).
-`services.geoip-updater` was broken and has been replaced by [services.geoipupdate](options.html#opt-services.geoipupdate.enable).
- PHP 7.3 is no longer supported due to upstream not supporting this version for the entire lifecycle of the 21.11 release.
- Those making use of `buildBazelPackage` will need to regenerate the fetch hashes (preferred), or set `fetchConfigured = false;`.
-`consul` was upgraded to a new major release with breaking changes, see [upstream changelog](https://github.com/hashicorp/consul/releases/tag/v1.10.0).

-`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).
-`tt-rss` was upgraded to the commit on 2021-06-21, which has breaking changes. If you use `services.tt-rss.extraConfig` you should migrate to the `putenv`-style configuration. See [this Discourse post](https://community.tt-rss.org/t/rip-config-php-hello-classes-config-php/4337) in the tt-rss forums for more details.
- The following Visual Studio Code extensions were renamed to keep the naming convention uniform.
-`services.uptimed` now uses `/var/lib/uptimed` as its stateDirectory instead of `/var/spool/uptimed`. Make sure to move all files to the new directory.
- Deprecated package aliases in `emacs.pkgs.*` have been removed. These aliases were remnants of the old Emacs package infrastructure. We now use exact upstream names wherever possible.
-`programs.neovim.runtime` switched to a `linkFarm` internally, making it impossible to use wildcards in the `source` argument.
- The `openrazer` and `openrazer-daemon` packages as well as the `hardware.openrazer` module now require users to be members of the `openrazer` group instead of `plugdev`. With this change, users no longer need be granted the entire set of `plugdev` group permissions, which can include permissions other than those required by `openrazer`. This is desirable from a security point of view. The setting [`harware.openrazer.users`](options.html#opt-services.hardware.openrazer.users) can be used to add users to the `openrazer` group.
- The fontconfig service's dpi option has been removed.
Fontconfig should use Xft settings by default so there's no need to override one value in multiple places.
The user can set DPI via ~/.Xresources properly, or at the system level per monitor, or as a last resort at the system level with `services.xserver.dpi`.
- The `yambar` package has been split into `yambar` and `yambar-wayland`, corresponding to the xorg and wayland backend respectively. Please switch to `yambar-wayland` if you are on wayland.
- The `services.minio` module gained an additional option `consoleAddress`, that
configures the address and port the web UI is listening, it defaults to `:9001`.
To be able to access the web UI this port needs to be opened in the firewall.
- If `exfat` is included in `boot.supportedFilesystems` and when using kernel 5.7
or later, the `exfatprogs` user-space utilities are used instead of `exfat`.
- The `todoman` package was upgraded from 3.9.0 to 4.0.0. This introduces breaking changes in the [configuration file](https://todoman.readthedocs.io/en/stable/configure.html#configuration-file) format.
## 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.
-`python3` now defaults to Python 3.9. Python 3.9 introduces many deprecation warnings, please look at the [What's New In Python 3.9 post](https://docs.python.org/3/whatsnew/3.9.html) for more information.
-`qtile` hase been updated from '0.16.0' to '0.18.0', please check [qtile changelog](https://github.com/qtile/qtile/blob/master/CHANGELOG) for changes.
- 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.
- The [networking.wireless.iwd](options.html#opt-networking.wireless.iwd.enable) module has a new [networking.wireless.iwd.settings](options.html#opt-networking.wireless.iwd.settings) option.
- The [services.syncoid.enable](options.html#opt-services.syncoid.enable) module now properly drops ZFS permissions after usage. Before it delegated permissions to whole pools instead of datasets and didn't clean up after execution. You can manually look this up for your pools by running `zfs allow your-pool-name` and use `zfs unallow syncoid your-pool-name` to clean this up.
- Zfs: `latestCompatibleLinuxPackages` is now exported on the zfs package. One can use `boot.kernelPackages = config.boot.zfs.package.latestCompatibleLinuxPackages;` to always track the latest compatible kernel with a given version of zfs.
- Nginx will use the value of `sslTrustedCertificate` if provided for a virtual host, even if `enableACME` is set. This is useful for providers not using the same certificate to sign OCSP responses and server certificates.
