Web SDK release notes (historical)

Historical Experiences SDK release notes for Web, 2026 onward. For current releases, use the latest published release notes. For 2025 and earlier, see Web SDK release notes (historical, 2025 and earlier).

0.36.3 - Web

Date: 2026-08-06

Added

CMS-configured row and grid widgets

widgetRemoteIdentifier lets content managers control row and grid widget settings in Experiences CMS. Set it to the widget remote ID when you initialize the widget. See BlazeSDK class and CMS-configured widgets.

Closed-caption styling

Story, moment, and video player themes now support closed-caption styling, so you can customize caption font and placement. See Video theme.

Non-vertical aspect ratios in the Moments player

The Moments player now supports non-vertical video aspect ratios.

Fixed

Ad loading placeholders

Loading placeholders stayed visible when a GAM ad returned no fill.

VAST ad resizing

VAST ads didn't resize correctly after device rotation or player size changes.

Media seek bar

Fixed media seek bar issues.

0.36.1 - Web

Date: 2026-07-20

Added

Composite data source

A new composite() builder on DataSourceBuilder combines several data sources into a single deduplicated feed, configured with BlazeCompositeDataSourceEntry entries. See DataSourceBuilder.

Item click thumbnail

setOnItemClick() now includes contentThumbnailUrl on ItemClickContext: the URL of the clicked item's static thumbnail (not a GIF).

Multiple video ad placements

Videos can play more than one ad in a single video (pre-roll, mid-roll, and post-roll) when the content ad configuration provides adPercentages. If adPercentages is not set, behavior stays pre-roll only.

Start time sorting for live streams

StartTimeDesc and StartTimeAsc replace RecentlyStartingFirst/RecentlyStartingLast for sorting live streams by start time.

Fixed

Widget analytics fields

Restored missing content_type and generated_user_id on widget analytics events (widget_load and widget_visible).

IWidgetView.reload()

Blank player when content reload completed after the player had already opened.

User Activity

Streaming video (Live)

Streaming video (CMS Streams / live video) is supported starting with this version on Web. Use VideoFilterBuilder helpers such as liveOnly(), allStreams(), and custom({ contentTypes, streamStates }) to control which Videos and streams a widget or player shows. See Video content type delivery.

Aniview Cookie Sync for Ads

The SDK now performs server-side cookie sync on pages that run Aniview campaigns, speeding up programmatic demand and reducing ad latency.
