I have resolved this issue by adding the following rule to local_rules.xml.
<rule id="100014" level="0">
<if_sid>31533</if_sid>
<url>^/socket.io/</url>
<description>Ignoring NodeBB (socket.io).</description>
</rule>
Yesterday I already ask this question https://community.nodebb.org/topic/9658/changelog-between-release-versions-1-2-0-vs-1-1-2
See it here: https://github.com/NodeBB/NodeBB/milestone/46?closed=1

@torn2 everything added in 1.2.1 is listed in the 1.2.1 milestone.
