MustardOS “Jacaranda” Update: Color Controls, Smarter UI, and a Bit of Nostalgia

The MustardOS (muOS) team just dropped Jacaranda—version 2601.0—the first major update of 2026—and it’s packed with polish, personality, and performance tweaks. As a “stealth drop,” the team quietly rolled it out last week to iron out kinks before the big reveal. A patch (2601.1) is already in the works.

One standout feature? Hardware-injected overlays—think real-time brightness, battery, and volume HUDs that don’t hog CPU cycles. Works great across emulators (including RetroArch!) and GLES apps, though PortMaster users will have to wait for compatibility fixes.

Gamers with an eye for aesthetics (or accessibility) will love the global color controls and per-game filters, including presets for color-blind modes. And yes—you can now choose between organized playlists or gloriously chaotic folder sorting.

Bonus tidbits:

  • 📺 DVD-bounce screensaver (yes, really)
  • 🎮 On-device community news & “Game of the Month” updates
  • ⏱️ Activity tracker that builds your Play Style profile—exportable as HTML, for sharing with friends or flexing online

As always: back up before updating. muOS devs aren’t liable for lost saves—but they are listening (check the Discord and forums).
