Why knowing your Salesforce release matters
Knowing which Salesforce release your org is on (Winter, Spring, Summer + year) helps you plan feature adoption, test release updates, and prepare for maintenance windows. Below are practical, reliable ways to determine your orgs current release and instance.
Method 1 — From Setup (Company Information & Instance)
1. In Salesforce, go to Setup > Company Information.
2. Look for the Instance value (for example: NA45, EU17, etc.).
3. Take that instance name and check Salesforce Trust (trust.salesforce.com) to see the currently applied release for that instance.
Method 2 — Use Salesforce Trust site
1. Open trust.salesforce.com.
2. Enter the instance (e.g., NA45) in the instance search box or navigate to the instance page.
3. The instance page shows the current release name (for example, Summer ’25), upcoming maintenance, and preview windows.
Method 3 — Via CLI (SFDX)
If you use Salesforce DX, you can get your orgs instance URL and then check Trust.
sfdx force:org:display --targetusername myOrgAlias
Look for Instance URL or Instance in the command output (something like https://na45.my.salesforce.com). Use the instance code (NA45) on trust.salesforce.com to find the release.
Method 4 — From API / Login Response
When you authenticate via the SOAP API, the login response contains a serverVersion value that corresponds to an API version. While the API version number itself doesnt directly say “Summer ’25”, you can map API versions to release names via Salesforce release notes. Alternatively, use the instance from the login response, then check Trust for the release name.
Method 5 — UI Clues & Release Updates
– In Salesforce Classic, the UI footer sometimes shows the release name (e.g., Winter ’24).
– In Setup, search for Release Updates to see org-specific update information and whether specific release-related updates are pending.
Quick Apex snippet to get your orgs instance
String host = URL.getSalesforceBaseUrl().getHost();
System.debug('Instance host: ' + host);
This prints the host (for example na45.salesforce.com) in debug logs. Extract the instance token (na45) and check trust.salesforce.com.
Quick workflow summary
– Preferred manual approach: Setup > Company Information → take Instance → check trust.salesforce.com.
– Preferred automation approach: Use sfdx force:org:display or a SOAP/API login to retrieve instance, then query Trust programmatically if required.
Notes & tips
– Sandboxes follow a preview schedule; use the Trust site to see sandbox preview windows (preview may show a different upcoming release).
– Always validate features in a sandbox before release weekends.
– Map API version numbers to release names using Salesforce release notes when you only have serverVersion.
Conclusion
The most reliable way to check your orgs release is to locate the instance (from Setup or SFDX) and then consult trust.salesforce.com for that instances current release and schedule. This approach works for production and sandbox orgs and supports both manual and automated checks.
