 > There can be breaking changes between beta versions. Therefore we recommend pinning the package version to a specific beta version in your Gemfile. This way you can install the same version each time without breaking changes unless you are intentionally looking for the latest beta version.

 ## Support
 
 New features and bug fixes are released on the latest major version of the Stripe Ruby library. If you are on an older major version, we recommend that you upgrade to the latest in order to use the new features and bug fixes including those for security vulnerabilities. Older major versions of the package will continue to be available for use, but will not be receiving any updates.
