Unity Ads 1.5x is now deprecated

Unity Ads 1.x has now been removed from the Asset Store and the public release repositories.

Live games still using Unity Ads 1.x will continue serving ads and monetizing.

For new integrations please use Unity Ads 2.0

Unity Ads 2.0 Asset Store -package: https://www.assetstore.unity3d.com/en/#!/content/66123

Note: Unity Ads 2.0 is available via the services window integration since Unity 5.5 - earlier editor versions still use version 1.5 - if you want to use an earlier editor with Ads 2.0 - please use the Asset Store package.

If you encounter any issues or have any questions - feel free to post them here or raise a support ticket by sending an e-mail to: unityads-support@unity3d.com

 

Actually even better than that - Unity Ads 2.x is open source for vetting purposes just like 1.x was.
