# [2025-05-21] v2.2.1 - Game UIs

Improved some workflows to support the rollout of our game UIs.

To upgrade from a previous version:

- make sure to update the various `onejs-core` and `onejs-preact` to `^2.0.0`

- The following defaults have changed:

- `postcss.config.js`, `tailwind.config.js`, `tsconfig.json`

- `input.css`, `.vscode/tasks.json`

- You can delete them and run scene with ScriptEngine again (be mindful if you have custom changes)

To install OneJS's Game UIs, you can now run:

```bash

npx oj add all

```

This will work as long as you have a `premade-uis.tgz(.bytes)` file anywhere in your Assets/ folder. This file is only included in the OneJS Asset Store package.

# [2024-12-02] v2.1.6 - Preparation for Editor UI

We’re releasing this now, ahead of the Editor UI update (expected in a couple of weeks), as it includes significant improvements and bug fixes that are worth rolling out early.

If you are updating an existing project, make sure to also bump the `onejs-core` package to `^1.0.6` in your package.json.
