Keep in mind the update is not releasing today. Firemonkeys has just released the patch notes early.

The update is being deployed to everyone now. It may be a while before you are able to update your game.

There will be two new cars up for grabs (if you complete their special events):

Underground Rivals

Blackridge Rivals is out, and Underground Rivals is in. This feature is such a big deal - it has its own dedicated Blog Post and Dev Diary.

First up, we have Country Mile, which will be set on our brand new track Erwick County.

Alongside Underground Rivals, there will be a new area to race in called Erwick County.

Erwick County

Debuting alongside Underground Rivals, Erwick County is a new countryside region, washed in a gorgeous Autumn palette. The new region features dawn and overcast variants, offering new medium-difficulty races against a fresh backdrop.

With Blackridge Rivals ending, players will get some wraps according to their highest ranking from all of Blackridge Rivals seasons.

Championship Wraps

Blackridge Rivals may be over, but not without a small token to remind you of your successes. Three Tiered Championship Wraps will be awarded to players based on their highest ever ranking in Blackridge Rivals!

Anyone who reaches at least Prospect will receive ONE WRAP, Challenger and above will receive TWO WRAPS, and Icon will get all THREE WRAPS! Check them out!

Level cap will be increased from Level 100 to Level 500.

Rep Cap Increase

Player Rep Cap has raised from 100 to 500! To celebrate the efforts of racers who've reached the previous cap, with this update we're awarding them with 200 Gold.All your previously accumulated Rep post-level 100 will contribute to your progress once the cap raises. This means that you will be boosted to the level you would have otherwise been.Rep-up rewards change after reaching Level 100. We know a lot of players have asked for increases to storage, so, every new Rep Level gained will reward racers with 5 new permanent storage slots. Fuel refills will still be rewarded post-100 (a one-time fuel refill will only occur at update launch for your Rep Level boost). Gold will not be a Rep Reward from 100 up.

With the new update, there will be adjustments to the Daily Assignments.
