26.3 brings a nice set of operational wins across catalog hygiene, pricing/inventory workflows, and admin/security visibility — the kind of updates that quietly reduce day-to-day friction.

What’s new in 26.3 (high-level)

• Search products by price & availability (Business Manager)
  New filters in Advanced Search help you spot catalog issues faster — for example, products missing prices or affected by stock/availability conditions — so teams can fix data problems before they hit the storefront.
• Omnichannel Inventory resilience
  The release also introduces a resilience-focused improvement for Omnichannel Inventory scenarios, aimed at keeping sales flows smoother under real-world conditions.
• Price and Attribute Search (Beta)
  A beta capability geared toward more precise searching when both price and product attributes are involved.
• PII access monitoring in Business Manager
  You can configure Business Manager to create security log entries when a user views a shopper’s personal identification information (PII), improving auditability for sensitive access.
• More granular price replication
  Support for replicating specific prices from staging to production helps reduce “all-or-nothing” replication and keeps changes tighter and more controlled.
• Default Domain (GA) for simpler testing
  Generally available: a Salesforce-managed, eCDN-enabled hostname per instance (dev/stage/prod), designed to simplify testing without extra domain setup work.
• Faster navigation between Business Manager apps
  Small, but welcome: improvements that make moving between Business Manager apps quicker.

Why it matters

If you’re running multiple catalogs, price books, or frequent release cycles, 26.3 is a “quality of life” release: fewer blind spots in pricing/availability, tighter replication control, clearer audit trails for sensitive access, and a bit less admin friction in Business Manager.
