9.19 patch xin notes--what scuttle changes are they referencing?

The notes say "Xin could use some love after the Scuttler changes decreased his early game power value so we're helping out." What changes to scuttler are the patch notes referring to? I looked through the notes for the past few patches, and the rest of the 9.19 notes, but don't see anything about scuttler changes other than the teemo change (scuttle not triggering shrooms).
