The attribute <literal>linuxPackages_latest_hardened</literal>
was dropped because the hardened patches lag behind the
upstream kernel which made version bumps harder. If you want
to use a hardened kernel, please pin it explicitly with a
versioned attribute such as
<literal>linuxPackages_5_10_hardened</literal>.

The setting

<literal>&quot;VERBOSE&quot;</literal>
<literal>&quot;INFO&quot;</literal>. This brings NixOS in line
with upstream and other Linux distributions, and reduces log
spam on servers due to bruteforcing botnets.

However, if

Sway: The terminal emulator <literal>rxvt-unicode</literal> is
no longer installed by default via

default configuration uses <literal>alacritty</literal> (and

using a customized configuration and not installing

The wordpress module provides a new interface which allows to
use different webservers with the new option
<link xlink:href="options.html#opt-services.wordpress.webserver"><literal>services.wordpress.webserver</literal></link>.
Currently <literal>httpd</literal> and
<literal>nginx</literal> are supported. The definitions of
wordpress sites should now be set in
<link xlink:href="options.html#opt-services.wordpress.sites"><literal>services.wordpress.sites</literal></link>.
</para>
<para>
Sites definitions that use the old interface are automatically
migrated in the new option. This backward compatibility will
be removed in 22.05.

The <literal>myhostname</literal> module is placed before
the <literal>resolve</literal> (optional) and

The <literal>mymachines</literal> module, which provides

The
<link xlink:href="options.html#opt-services.syncoid.enable">services.syncoid.enable</link>
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
<literal>zfs allow your-pool-name</literal> and use
<literal>zfs unallow syncoid your-pool-name</literal> to clean
this up.

Nginx will use the value of
