Introduction: StudioBytes and Uma Musume
StudioBytes is the name some fans use when sharing rumors and theories about updates to Uma Musume JP: Pretty Derby (JP). The game itself is made by Cygames. This version, 2.18.1, ships small tweaks and gameplay polish. It’s not a massive update, but it’s a steady step forward.

History of Uma Musume JP and Versions
The game has seen many updates since launch in 2021. Version 2.18.1 is the latest, but here’s how it fits in:
| Version | Approx. Release | Key Notes |
|---|---|---|
| 2.17.x | Mid-2025 | Seasonal event updates, gacha banners |
| 2.18.0 | Early-August 2025 | Event rollout, minor bug fixes |
| 2.18.1 | Current | Small gameplay adjustments and stability patches |
Version 2.18.1 dropped without fanfare. It seems focused on fine-tuning existing systems, not adding big features.

- UI and Event Tweaks – Slight adjustments to screens related to ongoing events or training.
It’s not flashy, but it helps things run smoother.
