Yeah, definitely not a necessity to update to it unless those little triangles on the needle tuner really bug you that they're not there with a custom color. Otherwise, you can skip it. Mostly I wanted to just make people aware, in case they stumbled across it.

Custom UI Plugins - Q-Tune is now open for tinkering!
You can now install custom tuner screens and standby screens onto Q-Tune, built by the community (or by you). Plugins drop right into Q-Tune and show up in your settings menus alongside the built-in screens.
There are two kinds of plugins: active tuner styles and standby/screensaver screens.
Install, enable, disable, and remove plugins using USB Drive mode or use the built-in Wi-Fi server and open the new Plugins page from your web browser.
Plugins are sandboxed and crash-safe: if a plugin misbehaves, Q-Tune automatically falls back to a built-in screen and sets the troublemaker aside so your tuner always keeps working.
NEW Q-Tune SDK - build and share your own tuners and standby screens
We've released a free, open-source SDK so anyone can create plugins for Q-Tune:
No toolchain to install. Everything builds inside Docker, so you don't need to set up a full embedded development environment. There are two ways to build: scaffold a C++ project: the classic way, or use Claude Code to help you create a plugin with little-to-no coding.
There are five complete examples to learn from and remix: Gauge and Phase (tuner displays), plus Bouncer, Hyperdrive, and Jamagotchi (standby screens, including one with its own persistent state).
Each frame, your plugin receives the detected note, how sharp/flat it is, and the user's settings. You can use this to draw anything you can imagine on the 240×320 screen, in portrait or landscape, with touch support.
It's Apache-2.0 licensed, so you're free to build, share, and even sell your own plugins.
Developer Tools menu - A new Settings > Advanced > Developer Tools > Test Signal option meant for developers to see sample tuning data without plugging in a guitar. It's off by default.
Here's a quick preview of the plugins currently bundled with the SDK:
