Here are the LoL Patch 13.9 patch notes

With the 2023 Mid-Season Invitational update in the rearview mirror, Riot Games is now turning its focus to League of Legends ranked play balance and the champions and items that have seen spiking win rates in season 13’s early months.

The League pro scene may be taking a deep breath before MSI 2023, but battles across Summoner’s Rift certainly don’t stop for anyone or anything. The next update cycle, 13.9, began properly on Monday, April 23. While the development boss Matt “Phroxzon” Leung-Harrison is normally the one unveiling all the planned buffs, nerfs, and changes coming in the first May patch, the preview was released by the League of Legends Dev Team account.
