Grafana is now built without support for phantomjs by default. Phantomjs support has been
<link xlink:href="https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/">deprecated in Grafana</link>
and the <package>phantomjs</package> project is
<link xlink:href="https://github.com/ariya/phantomjs/issues/15344#issue-302015362">currently unmaintained</link>.
It can still be enabled by providing <literal>phantomJsSupport = true</literal> to the package instanciation:
<programlisting>{
services.grafana.package = pkgs.grafana.overrideAttrs (oldAttrs: rec {
phantomJsSupport = false;
});
}</programlisting>
</para>
</listitem>
<listitem>
<para>
The <link linkend="opt-services.supybot.enable">supybot</link> module now uses <literal>/var/lib/supybot</literal>
as its default <link linkend="opt-services.supybot.stateDir">stateDir</link> path if <literal>stateVersion</literal>
is 20.09 or higher. It also enables number of
<link xlink:href="https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Sandboxing">systemd sandboxing options</link>
which may possibly interfere with some plugins. If this is the case you can disable the options through attributes in
<option>systemd.services.supybot.serviceConfig</option>.
</para>
</listitem>
<listitem>
<para>
The <literal>security.duosec.skey</literal> option, which stored a secret in the
nix store, has been replaced by a new
<link linkend="opt-security.duosec.secretKeyFile">security.duosec.secretKeyFile</link>
option for better security.
</para>
<para>
<literal>security.duosec.ikey</literal> has been renamed to
<link linkend="opt-security.duosec.integrationKey">security.duosec.integrationKey</link>.
</para>
</listitem>
<listitem>
<para>
The initrd SSH support now uses OpenSSH rather than Dropbear to
allow the use of Ed25519 keys and other OpenSSH-specific
functionality. Host keys must now be in the OpenSSH format, and at
least one pre-generated key must be specified.
</para>
<para>
If you used the <option>boot.initrd.network.ssh.host*Key</option>
options, you'll get an error explaining how to convert your host
keys and migrate to the new
<option>boot.initrd.network.ssh.hostKeys</option> option.
Otherwise, if you don't have any host keys set, you'll need to
generate some; see the <option>hostKeys</option> option
documentation for instructions.

Since this release there's an easy way to customize your PHP install to get a much smaller
base PHP with only wanted extensions enabled. See the following snippet installing a smaller PHP
with the extensions <literal>imagick</literal>, <literal>opcache</literal> and
<literal>pdo_mysql</literal> loaded:
<programlisting>
environment.systemPackages = [
(pkgs.php.buildEnv { extensions = pp: with pp; [
imagick
opcache
pdo_mysql
]; })
];</programlisting>
The default <literal>php</literal> attribute hasn't lost any extensions -
the <literal>opcache</literal> extension was added there.
All upstream PHP extensions are available under <package><![CDATA[php.extensions.<name?>]]></package>.
</para>
<para>
The updated <literal>php</literal> attribute is now easily customizable to your liking
by using extensions instead of writing config files or changing configure flags.
Therefore we have removed the following configure flags:

Deluge 2.x was added and is used as default for new NixOS
installations where stateVersion is >= 20.09. If you are upgrading from a previous
NixOS version, you can set <literal>service.deluge.package = pkgs.deluge-2_x</literal>
to upgrade to Deluge 2.x and migrate the state to the new format.
Be aware that backwards state migrations are not supported by Deluge.

To switch to a specialised configuration at runtime you need to
run:

The <package>notmuch</package> package move its emacs-related binaries and
emacs lisp files to a separate output. They're not part
of the default <literal>out</literal> output anymore - if you relied on the

the <literal>notmuch.emacs</literal> output.
