 ## Security Library
 
-This library controls how users sign-in and access services. We recommend you always take the latest version of our library in your app when possible. We use [semantic versioning](http://semver.org) so you can control the risk associated with updating your app. As an example, always downloading the latest minor version number (e.g. x.*y*.x) ensures you get the latest security and feature enhanements but our API surface remains the same. You can always see the latest version and release notes under the Releases tab of GitHub.
