Upcoming Changes to RaceRoom’s Shared Memory API – September 24th Update
On [b]September 24, 2025[/b], RaceRoom will receive a major update that introduces fixes and improvements to the [b]shared memory API[/b]. These changes are necessary to support new features such as the upcoming [b]Hypercars / LMDh hybrid systems[/b] and their [b]virtual energy systems[/b].
Because of the scope of these additions, the shared memory block will [b]no longer be backward compatible[/b]. This means that third-party apps, dashboards, motion rigs, and other tools that rely on the shared memory API will stop working correctly unless they are updated.
If you are an app developer using RaceRoom’s shared memory interface:
The documentation and a sample program can be found here: [url="https://github.com/sector3studios/r3e-api/tree/master"]RaceRoom Shared Memory API on GitHub[/url]
To help with the transition, we can provide [b]early access to a game build[/b] that includes the updated shared memory structure. If you would like access, please [url="https://discord.com/invite/raceroom"]join our discord[/url] and head over to the [url="https://discord.com/channels/254906072748261376/751700241169907723"]#Apps channel[/url] where you also can participate in the conversation and submit your own wishes and requirements for further modifications of our API.
We encourage all developers to update their tools ahead of the September 24th release to ensure a smooth experience for their users.
Thank you for your continued support in expanding the RaceRoom ecosystem!
