Dr. Robotnik's Ring Racers Version 2.4 Release Candidate 7

Kart Krew Dev — Wed 22 October 2025

Dr. Robotnik’s Ring Racers version 2.4 is just on the horizon!

This is a Release Candidate version; the design and features are mostly final, but since there are a lot of changes in this release, we’re making it available in a pending state to check for technical issues and critical bugs.

If you’d like to try out the newest features and fixes, and don’t mind running into potential bugs, please give this version a try; let us know if you run into trouble via GitLab or on Discord.

We want to thank all the dedicated players in our Discord server who have helped rigorously test these pre-release versions and provided valuable feedback so far, and to our community contributors who’ve helped fix issues reported by them. This testing period was an incredible success, and the game is all the better for it.

If you’re just arriving, please read the previous release candidate notes first! This page won’t list any changes made in prior RC versions.

WARNING!

This is a Release Candidate build. You may encounter bugs, lose progress, or otherwise have weird stuff happen to you.

We recommend installing to a new location and backing up your save files (ringdata.dat, ringprofiles.prf, ringconfig.cfg). Installations upgraded to 2.4 cannot be reverted to 2.3; you MUST back up your data to do this.

BACK UP YOUR EXISTING INSTALLATION, OR YOU COULD IRREVERSIBLY LOSE EVERYTHING!

• Windows
• macOS
• Flatpak org.kartkrew.RingRacers is available under the Flathub Beta channel only for non-stable releases.
• GitHub Release Page

NOTE: There are still more fixes coming! However, we’ve already made enough changes that we’d like to battle-test the latest stuff while we work.

Core Gameplay

• Tethering now immediately stops while holding a completed Insta-Whip charge (previously 4-second delay).
  • Heavyweights are more agile than ever, and their ability to make long-range slingshot overtakes is strong enough without also attaching a high-speed attack. This is meant to make Whip interactions a little more predictable by limiting the overall threat range.
• Activating Ring Bail while under the effect of Eggman Mark now detonates the Mark. (This will almost always kill you.)
• Moderately increased the top speed of players under the effect of Eggman Mark.
  • Now that leaders can no longer Mark themselves, we’re free to sharpen the Eggman Mark’s double-edge. Pass to the leader at your peril!
• Reduced bot rubberbanding while cornering.
• Adjusted the appearance of infinite height tripwires.
• Stone Shoe’s chain distance has been shortened, and the shoe itself will now follow the player faster.
  • The link change from RC6 was erroneously a cosmetic change only; it has been properly adjusted now.
• You can no longer use items while on a Bungee.
• Fixed irregularities in stat-based amp payouts, and improved amp gains for lightweight speed characters.
• Class C will be able to interact with Overdrive more regularly, and class G earns more speed for brawling.
• Fixed certain items sometimes paying out 0 amps in single-player modes.

Interface

• The chat window will not trigger bound actions on character keys, e.g. it will not take screenshots if screenshot is bound to the ‘H’ key. - !40
• When choosing a character or follower color in the player setup screen, the “Default” button will now also cycle in the profile’s selected character or follower color in addition to the skin default and character-opposite colors. - !34
• In the Cup Select screen in Match Race and multiplayer, you can now queue a whole Cup into the level queue - !11
• The rewind button when viewing replays now rewinds 10 seconds backwards instead of 5.

Accessibility

• In Reduce VFX, the silver duration-based player sprite flashing during Invincibility is disabled.
• In Reduce VFX, the flashing barrier around the player (distinct from the Sonic Boom effect) no longer draws.
• In Reduce VFX, the Sonic Boom barrier when below 150% of the current Sonic Boom threshold is semitransparent instead of rapidly flashing.
• In Reduce VFX, electricity above stage 2 drift boost charge no longer rapidly flashes.
