Some last bug fixes before stable release.
Strelya72 Release notes is not the place to file bug reports, please use our issue tracker github.com/Scirra/Construct-3-bugs/issues.
We already target SDK 28, and have done for quite awhile. You can see the target in your log message, which unfortunately does not include any actual errors. If your project is not exporting for some reason then please file a bug for us including the affected project and your export settings.
Yes, sorry, the error was related to the "UnityAds" plugin.
Thanks for the link :)
