|Knowledge Article Number||000220248|
|Resolution||Here are the steps to find the release version of an org:
1. If you are not using customized logo you can check the logo at the top left of the page. This will show the release version you are in e.g. Summer "15.
2. Navigate to Home Tab
3. Look at the right hand side of the page which will have a link like "Discover <Release Name>" e.g. "Discover Summer '15"
If the "Discover <Release Name>" is hidden, since there is a feature for that, you can navigate to trust.salesforce.com | status.
Click on the instance name, you will see which release the instance is on in the upper right corner.
