The ELK stack: <varname>elasticsearch</varname>, <varname>logstash</varname> and <varname>kibana</varname>
has been upgraded from 2.* to 6.3.*.
The 2.* versions have been <link xlink:href="https://www.elastic.co/support/eol">unsupported since last year</link>
so they have been removed. You can still use the 5.* versions under the names
<varname>elasticsearch5</varname>, <varname>logstash5</varname> and
<varname>kibana5</varname>.

<para>
The elastic beats:
<varname>filebeat</varname>, <varname>heartbeat</varname>,
<varname>metricbeat</varname> and <varname>packetbeat</varname>
have had the same treatment: they now target 6.3.* as well.
The 5.* versions are available under the names:
<varname>filebeat5</varname>, <varname>heartbeat5</varname>,
<varname>metricbeat5</varname> and <varname>packetbeat5</varname>
</para>
<para>
The ELK-6.3 stack now comes with
<link xlink:href="https://www.elastic.co/products/x-pack/open">X-Pack by default</link>.
Since X-Pack is licensed under the
<link xlink:href="https://github.com/elastic/elasticsearch/blob/master/licenses/ELASTIC-LICENSE.txt">Elastic License</link>
the ELK packages now have an unfree license. To use them you need to specify
<literal>allowUnfree = true;</literal> in your nixpkgs configuration.
</para>
<para>
Fortunately there is also a free variant of the ELK stack without X-Pack.
The packages are available under the names:
<varname>elasticsearch-oss</varname>, <varname>logstash-oss</varname> and
<varname>kibana-oss</varname>.
