It has been a tough time for all since the last update, but things have been moving steadily along. In the past few months there has been a concerted effort to revamp and update the project ready for Unity 2022, as well as migrating the source repository over to GitHub and refreshing all the things.
We hope the new release is better for everyone and we have paid close attention to the editor menus and places to find all the controls for this release.
For customers upgrading from earlier versions of Unity to Unity 2020, please be aware of the Breaking change related to Text Based components. You will need to manually replace any UI using the older ```Text``` component and replace them with ```TextMeshPro``` versions. This is unavoidable due to Unity deprecating the Text component.
> New users to 2022 are unaffected as all the Editor commands have been updated to use the newer TextMeshPro versions.
For more details, see the [deprecation notice](https://github.com/Unity-UI-Extensions/com.unity.uiextensions/discussions/428) on GitHub.

We recommend using the UPM delivery method. If you are using the Unity asset, there should be no issues updating but if you have a problem, just deleted the old Unity-UI-Extensions folder and import the asset new.
## [How do I get set up?](https://unity-ui-extensions.github.io/UPMInstallation.html)
The recommended way to add the Unity UI Extensions project to your solution is to use the Unity package Manager. Simply use the Unity Package Manager to reference the project to install it
New for 2020, we have added OpenUPM support and the package can be installed using the following [OpenUPM CLI](https://openupm.com/docs/) command:
Alternatively, you can also add the package manually through the Unity package manager using the scope ```com.unity.uiextensions```, see the [Unity Package Manager docs](https://learn.unity.com/tutorial/the-package-manager) for more information.
Either clone / download this repository to your machine and then copy the scripts in, or use the pre-packaged .UnityPackage for your version of Unity and import it as a custom package in to your project.
Got a script you want added? Then just fork the [GitHub repository](https://github.com/unity-UI-Extensions/com.unity.uiextensions) and submit a PR. All contributions accepted (including fixes)
All scripts conform to the BSD3 license and are free to use / distribute. See the [LICENSE](https://raw.githubusercontent.com/Unity-UI-Extensions/com.unity.uiextensions/release/LICENSE.md) file for more information =
As this repo was created to support my new Unity UI Title ["Unity 3D UI Essentials"](http://bit.ly/Unity3DUIEssentials), in the downloads section you will find two custom assets (SpaceShip-DemoScene-Start.unitypackage and RollABallSample-Start.unitypackage). These are just here as starter scenes for doing UI tasks in the book.
