iOS SDK - Changelog

Release history for the MDN11 iOS SDK.

v3.2.9

2026-09-28

Added

  • Publishers can now observe which ad the SDK would show next: a new bestLoadedAdListener and bestLoadedAd snapshot getter on each ad type
  • Report that an impression for an ad unit went to an ad source outside the MDN11 SDK via notifyLossToExternal(price: Decimal?) on all supported ad formats.

Fixed

  • A banner or MREC refreshed in place by a mediation network now forwards a paid event to the publisher as revenue for every refresh, instead of only the first
  • Various internal fixes and improvements

v3.2.7

2026-09-22

Added

  • AdInfo extended - now carries adUnitID, sdkPlacementID, and extraParameters: network-specific load-response data keyed by network (e.g. "google_admob" / "google_ad_manager" with fields from AdMob/GAM's ResponseInfo, including the mediation group id)
  • Google Ad Manager (GAM) MREC - MREC ads are now supported through GAM mediation
  • Report the loaded ad source as AdInfo.adNetworkName for GAM mediation proxies

Fixed

  • Various fixes and improvements

Added

  • Hybrid initialization: the SDK can now start immediately from a publisher-provided static config while the remote config is fetched from hostUrls in the background and applied when it arrives
