This release fixes Razor Freestyle Scooter multiplayer startup and race disconnects, and keeps netplay input logs available only as an internal diagnostic feature.
- Starting netplay in Razor now lets the host coordinate a fresh boot of both games with the link connected. The reboot explicitly bypasses autosave loading on both machines.
- Opposing directional inputs are resolved consistently, preventing the race disconnect reproduced from a supplied input log.
- Netplay diagnostic logs capture every player's input and rollback timing. They are hidden and disabled by default; developers can opt in with
-Dcoffeegb.netplay.inputRecording=true. Ordinary input recording and playback are unchanged.

Fixed issues

Razor remains racing after the input sequence that previously broke the link (#663).
Known platform limitations
On macOS, game controllers require a compatible system SDL2 installation; keyboard input and emulation remain usable without it.
