in League of Legends

An earlier description of Update 13.1, which is coming soon to League of Legends. What exactly will change?

What changes will the first update to hit League of Legends in 2023 bring?

Riot’s staff took a vacation before Christmas, planning only for the mid-year update 12.23b, from which patches hit League of Legends on December 15. Since then, the game hasn’t seen changes, and those are expected to appear soon – in update 13.1.

So far, you could read posts that talked about individual fixes announced by the developers. Now, however, a detailed description of the patch has already been made available. What exactly can be found in it?
