There is a readme file in the archive of each 7-6-x zip archive file which describes what's included inside the archive.
The second post of the 7.6.1 version discussion thread also provides answers regarding the release and the patch. You should skim through that whole thread, as it may contain other information which you could find useful.

The 7.6.1 install archive was refreshed 20180111 and includes all the patches. So if you've installed 7.6.1 and the control panel displays 220.127.116.11 as the version.number, you already have 18.104.22.168 patched. You're set to go.
