OSX El Capitan update (?) 25 september 2017 (?)

[huug]

Hello,

I am running the latest El Capitan version 10.11.6 (15G1611)

Today, OSX Software Update App is asking me to update to a version 10.11.6 with release date 25 september 2017.
All together with Safari 11.0

Cannot find any information on this?

But Safari 11 is there, with date Sep 19
