Release notes for the IMA HTML5 SDK

[Interactive Media Ads SDK]

Hi all,

We are creating a new thread for IMA HTML5 SDK release notes. We will post here for every new SDK release that contains public changes. To limit the amount of noise on the thread, we will not post for releases where "Service Release. No new features." is the only note. Follow this thread for continuing IMA HTML5 release note updates

This thread is replacing the previous Release notes for the IMA HTML5 SDK thread.

The release notes are also available for:

- client-side: https://developers.google.com/interactive-media-ads/docs/sdks/html5/client-side/history

- DAI: https://developers.google.com/ad-manager/dynamic-ad-insertion/sdk/html5/history

If you have any questions regarding a particular release, please post a new topic in this forum and let us know that you are using the HTML5 version of the IMA SDK. If you're experiencing an error, please also include a link to a test page where we can see the issue.

Thanks,
IMA SDK Team
