We recently launched v3.0.7 of the Google Mobile Ads Unity Plugin. The updated v3.0.7 Unity package is available for download from the Google Mobile Ads Unity Plugin GitHub repository.
Native Ads Express
This release introduces support for Native Ads Express. With Native Ads Express, you can create CSS templates that define how ads are presented in your app (things like image sizes, fonts, colors, and so on). These CSS templates are used to generate ad creatives that complement the native look and feel of your app. You can find more information on integrating Native Ads Express into Unity applications in our developer docs.
The v3.0.7 release resolves compatibility issues with the IL2CPP scripting backend and the Google Mobile Ads Unity Plugin. This allows the use of the the IL2CPP scripting backend, a high-performance alternative to the Mono virtual machine and AOT compiler, in Unity applications with the Google Mobile Ads SDK.
The source code and a sample app for the plugin are available in our GitHub repo, as is a changelog for this release. If you have any questions about Unity integration, you can reach us on our developer forum.
