Why the Salesforce Winter ‘26 Release Matters
Salesforce has releases at least 3 times a year: spring, summer and winter. The winter release usually adds new performance and user interface changes and new tools for productivity. Testing these changes in advance is important for all the above reasons and will help you avoid any disruptions to your workflows, integrations and custom automations.
How to Find Your Salesforce Instance
If you don’t know your instance:
- In Salesforce, click Setup.
- Go to Company Information.
- Find the Instance field.
Knowing your instance ensures you can check your Winter ‘26 release date and prepare accordingly.
Winter ‘26 Sandbox Preview Dates
Sandbox previews are essential for testing the new release before it goes live in production.
- Preview Sandboxes: Upgrade around September 6, 2025
- Non-Preview Sandboxes: Upgrade closer to your production release date
You can also use a pre-release org to explore Winter ‘26 features earlier. However, pre-release orgs don’t include your current data or configurations, so sandbox testing is still necessary.
