Client SDK

Deprecation Policyanchor


We recommend that you make regular updates to your Braintree integration and update your client SDK version at least once a year.


Braintree makes regular updates to our client SDKs and follows semantic versioning guidelines with these updates. Whenever we need to make updates that will require code changes to existing integrations, we increase the major version number of the SDK to indicate that your integration will likely need to be updated for it to work with the newest version.

Examples of changes that would require a major version update:

  • Adding or dropping support for a specific version of a mobile OS or web browser
  • Security updates and changes

We do our best to add support for these without introducing a new major version, but if the changes required are great enough, they could result in a breaking change.

Platform supportanchor

We regularly review the most widely used browsers and OS versions for each of our client platforms and make support decisions based on this information.

The active major version of the Braintree iOS SDK will support, at minimum, the most recent version of iOS and the 2 previous versions (e.g., iOS 14, 13 and 12).

Status categoriesanchor

Client SDKs can have one of the following statuses:

StatusDescriptionState of development
ActiveAn active SDK version is the most current and fully supported SDK. It is the recommended version to be used by everyone. Only 1 exists at a time.This version will receive new features.
InactiveAn SDK becomes inactive once assigned a deprecation date. Any number can exist at a time.No new features will be added, only security updates.
DeprecatedProcessing will be supported for 1 year after the deprecation date, but you should upgrade immediately to avoid any disruption. Any number can exist at a time.Deprecated SDKs will not receive updates.
UnsupportedA retired SDK version is no longer supported by Braintree developers or Braintree Support. Any number can exist at a time.Processing for these SDKs can be suspended at any time.

Here is a visual representation of how client SDK major version statuses can change over time:

The README for each client SDK includes the status and deprecation dates for all major versions, and we will update these statuses as we release new major versions.


There may be unforeseen circumstances where we need to make exceptions to these statuses. If that happens, we will do our best to communicate these changes.

Tips for following SDK versionsanchor

We recommend watching the SDK on Github to stay informed about the latest version of the client SDK you're using.

In addition, we may occasionally contact you if there are upcoming changes that require updating your client SDK.
