As a Salesforce professional, knowing exactly which release your instance is running—whether it’s Spring, Summer, or Winter—is crucial for testing new features and troubleshooting bugs. While you can check this via “Company Information” in Setup, there is a much faster, programmatic way to do it using your My Domain URL.

The Quick Syntax

You can instantly view your release details by appending /releaseVersion.jsp to your My Domain URL.

The Syntax:

https://{YOUR_SALESFORCE_DOMAIN}.my.salesforce.com/releaseVersion.jsp

The Example:

If your domain is infallibletechie2-dev-ed, your URL will look like this:

https://infallibletechie2-dev-ed.develop.my.salesforce.com/releaseVersion.jsp

---

Why Use the URL Method?

Using the releaseVersion.jsp endpoint is often preferred by Developers and Architects over the standard UI because:

1. Speed: No need to navigate through the Setup menu.
2. No Login Required: In many configurations, this endpoint is accessible to verify the version without a full session handshake.
3. Automation: It can be used in health-check scripts.

Accessing via REST API (For Developers)

For those looking to automate environment audits, you can perform a simple REST API GET Request to the same URL.

Note: The response from this endpoint is returned in HTML format. If you are parsing this in a script (like Python or JavaScript), you will need to extract the version string from the HTML body.

Sample GET Request:

GET /releaseVersion.jsp HTTP/1.1
Host: infallibletechie2-dev-ed.develop.my.salesforce.com

Summary Table: Methods to Check Version

Method	Audience	Best For
URL Append	Admins / Analysts	Quick manual checks without navigating Setup.
REST API GET	Developers / Engineers	Automated environment inventory and CI/CD pipelines.

Final Pro-Tip

If you are an Architect managing a multi-org landscape, bookmarking these JSP links for your Production, Sandbox, and Scratch Orgs can save you significant time during the major Salesforce release windows (three times a year).
