Haedbidder.net October 25, 2021 Update.

We’ve release two important features today.

1. Global Schain support. Publisher can now add Schain ASI and SID in Site options. Additionally, usage of variables is possible. In the Haedbidder UI a variable like %may_variable% could be used and then defined on the page by a JavaScript built by Publisher.
2. Number of creatives within a Line Item. It is important to have enough creatives in order to deliver all the winning ads. Now this parameter is editable in HeadBidder UI via Tools/Orders menu.
