Blocks now support new strategies for collection-anchored recommendations and hand-picked product curation. Collection interaction strategies use real behavioral data to surface products related to a collection based on how shoppers interact with it. Three new strategies are available:

• Browsed Then Bought — Products frequently purchased by shoppers who browsed the collection
• Browsed Then Viewed — Products frequently viewed by shoppers who browsed the collection
• Trending in Collection — Products currently trending within the collection based on recent activity

Hand-picked products let you manually select specific products for a block and control their display order. When configured, hand-picked products take priority over collection-based selection — ideal for "Staff Picks," editorial features, or promotional spotlights.

Blocks also now support a fill fallback mode. Instead of replacing results when a fallback is triggered, fill mode appends products from the fallback to "top up" a partially filled block — giving you more control over how fallback chains behave.
