My SFCC Pills.

What’s New in 26.2 (high-level summary)

Operations & Admin

• Instance-level control for On-Demand Sandboxes (ODS): More granular control over when specific sandboxes are available, helping teams manage usage windows and reduce waste.
• Cleaner Business Manager session exits: Improved logout behavior so sessions can end without immediately bouncing into reauthentication.

Search & Merchandising

• Contextual Search (Beta): A new beta capability aimed at improving search result relevance by incorporating additional context signals beyond a simple keyword match.
• Saved filters for Product Lists: Merchandisers can reuse filter setups to speed up repetitive catalog/list management tasks and get to “the right view” faster.

Content & Page Designer

• Selective replication for Page Designer pages: More control over replication so you can choose which pages to replicate instead of treating replication as an all-or-nothing action.

Data & Sync

• Manual refresh for Data Maps: Added flexibility to refresh Data Maps on demand when you need it (instead of waiting for a background cadence).

Checkout Experience

• Prefill shipping and payment information: New support to prefill checkout inputs to reduce friction and accelerate conversions—especially useful for logged-in shoppers and repeat purchases.

APIs & Developer Tooling

• Stricter OCAPI version validation: Tighter input validation for OCAPI version numbers—review custom integrations and ensure your versioning is clean and compliant.
• OCAPI Explorer improvements: Better visibility into available Meta API versions directly inside the OCAPI Explorer to reduce guesswork during development.

Docs & Navigation

• Release notes moved: B2C Commerce release notes are now surfaced in a new location within Salesforce Help—update bookmarks and internal enablement links. Starting with the Salesforce Spring ’26 cycle (Release 260), Commerce release notes are now available in their new home here: Commerce Release Notes (Spring ’26).
