To open the patch notes in Roblox Rivals on PC , look for the book icon in the game’s settings/menu, then click it to bring up the update log or patch notes. A Reddit reply about Rivals specifically says the update log is reached through the settings icon and then the book icon, not a mailbox.

Quick steps

  1. Open Rivals on Roblox.
  2. Go to the main menu or in-game settings.
  3. Click the book icon to view the update log / patch notes.
  1. If you don’t see it, check the main menu for an updates/news entry or look in settings for an about/game info tab.

If it still doesn’t show

  • Make sure the game is fully updated.
  • Rejoin the server, since update notes can be tied to the current client version.
  • Some players report that notes can be hidden depending on the menu state or rollout timing.

Helpful note

A recent video guide on checking Rivals update logs also says to look in the main menu for an updates/news entry, and if needed, open settings for a game info/about section.

TL;DR

On PC, open Rivals → settings/menu → book icon to read the patch notes.
