Are you being ironic? R4 aggromech section on page 16.

Something as vague as "scout nerf" doesn't really qualify as a leak imo

OP stated that he heard from multiple sources that the scout was getting a nerf then in less than 24 hours the primary scout combo gets nerfed.

I might be ignorant, but what's the primary Scout nerf?

R4 no longer triggers when spending a focus to attack via Deadeye, or with a Blaster Turret. It now only triggers, basically, when you use a focus to modify your attack dice.

So the original definition "If a ship equipped with R4 Agromech is attacking with a secondary weapon that requires the ship to spend a focus token (such as a Blaster Turret), that ship may acquire a target lock on the defender and spend it during that attack." has been altered? I cannot find that info. Thanks for the clarification, but I need proof for my table-mate who's not buying it.

If you are using a search engine to find the FAQ you are probably still getting an old version of the FAQ. It generally takes several months for the search engine to rank the new FAQ higher than older ones. The current version is 4.2.1. The best way to ensure that you are looking at the most recent FAQ is to use the link on the FFG X-Wing product page. That and this forum are the top two hits for me when I use Google to search for "X-Wing FFG".

Once you are on the product page, scroll down. Near the bottom of the page you will find a Support section with subsections for Rules, FAQ, Tournament Resources, and Player Resources. Not surprisingly the FAQ section contains a link to the current version of the FAQ.
