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.

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
• GitHub Release Page
• The Flatpak release won’t be updated for prerelease versions. Technical Linux/Deck users can compile from source: check out tag v2.4-rc4 and use the assets linked in the GitHub release.

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.

Misc Fixes

• Fixed a bug that allowed players to underflow their Ring count and use Ring Bail for arbitrary amounts of speed.
  • “hopefully the last of major gameplay bugs” my ass
• Fixed a crash when players left the game while ringboosting.
• Fixed a crash that could occur when finishing a Grand Prix race with zero human players.
  • This normally couldn’t be triggered without cheats.

Course Changes

• Northern District - A killplane now triggers on the final lap as the girder cut raises, to prevent people from using boost items on the edge of specific slopes and launching past the fence.
• Withering Chateau - Added respawn lines to the outer edges of the first U-turn to prevent Bubble Shield from being smuggled and used to boost past the garden wall.
• Umbrella Rushwinds - Added more block players lines across bridge and changed respawn FOF to solid invisible wall.
• Sky Babylon - Crumble FOFs shouldn’t crush anymore, Waypoints are still moved out of way as an extra measure. Added an extra pillar on the last spiral to prevent unintended exploits/shortcuts.
• Autumn Ring - Added multiple Blockplayers linedefs.
• Lake Margorite - Extended death plane before the entrance to a cave to prevent exploits.
