How the numbers are worked out
The notes are Valve's, from their post on Steam, with each hero and item linked where its name leads a line. The numbers compare every recorded match in the 7 days before Valve posted the patch with the 7 days after, from the community deadlock-api. If Valve posted it days after the date in its title, the weeks run from the start of that date instead. A hero needs 500 matches in each window to be compared.
A change in win rate after a patch isn't all down to the patch: players try new things, other heroes change too, and a week is a short time. Heroes that moved without being named are listed so you can see how much of that there was.
