By default zfs pools will now be trimmed on a weekly basis.
Trimming is only done on supported devices (i.e. NVME or SSDs)
and should improve throughput and lifetime of these devices.
It is controlled by the <varname > services.zfs.trim.enable</varname> varname.

The zfs scrub service (<varname > services.zfs.autoScrub.enable</varname> )
and the zfs autosnapshot service (<varname > services.zfs.autoSnapshot.enable</varname> )
are now only enabled if zfs is set in <varname > config.boot.initrd.supportedFilesystems</varname> or
<varname > config.boot.supportedFilesystems</varname> . These lists will automatically contain
zfs as soon as any zfs mountpoint is configured in <varname > fileSystems</varname> .

The <literal > dynamicHosts</literal> option has been removed from the
<link linkend= "opt-networking.networkmanager.enable" > networkd</link>
module. Allowing (multiple) regular users to override host entries
affecting the whole system opens up a huge attack vector.
There seem to be very rare cases where this might be useful.
Consider setting system-wide host entries using
<link linkend= "opt-networking.hosts" > networking.hosts</link> , provide
them via the DNS server in your network, or use
<link linkend= "opt-environment.etc" > environment.etc</link>
to add a file into <literal > /etc/NetworkManager/dnsmasq.d</literal>

Before, it itself used <literal > set -u</literal> but was careful to unset it so other packages' code ran as before.

Polkit no longer has the user of uid 0 (root) as an admin identity.
We now follow the upstream default of only having every member of the wheel
group admin privileged. Before it was root and members of wheel.
The positive outcome of this is pkexec GUI popups or terminal prompts
will no longer require the user to choose between two essentially equivalent
choices (whether to perform the action as themselves with wheel permissions, or as the root user).

For NixOS configuration options, the <literal > loaOf</literal> type has
been deprecated and will be removed in a future release. In nixpkgs,
options of this type will be changed to <literal > attrsOf</literal>
instead. If you were using one of these in your configuration, you will
see a warning suggesting what changes will be required.
</para>
<para >
For example, <link linkend= "opt-users.users" > users.users</link> is a
<literal > loaOf</literal> option that is commonly used as follows:
<programlisting >
users.users =
[ { name = "me";
description = "My personal user.";
isNormalUser = true;
}
];
</programlisting>
This should be rewritten by removing the list and using the
value of <literal > name</literal> as the name of the attribute set:
<programlisting >
users.users.me =
{ description = "My personal user.";
isNormalUser = true;
};
</programlisting>

For NixOS modules, the types <literal > types.submodule</literal> and <literal > types.submoduleWith</literal> now support
paths as allowed values, similar to how <literal > imports</literal> supports paths.
Because of this, if you have a module that defines an option of type
<literal > either (submodule ...) path</literal> , it will break since a path
is now treated as the first type instead of the second. To fix this, change
the type to <literal > either path (submodule ...)</literal> .

The nginx web server previously started its master process as root
privileged, then ran worker processes as a less privileged identity user.
This was changed to start all of nginx as a less privileged user (defined by
<literal > services.nginx.user</literal> and
<literal > services.nginx.group</literal> ). As a consequence, all files that
are needed for nginx to run (included configuration fragments, SSL
certificates and keys, etc.) must now be readable by this less privileged
