SDK Deprecation Policy
We constantly strive to bring new features and fixes to Fitbit OS and our SDK, but each new SDK version creates additional overhead to our engineering process. Our deprecation strategy is defined so that as older SDK versions are removed from Fitbit Studio and our Command Line SDK, developers can plan their app updates accordingly.
We always plan to always support two SDK versions concurrently. This means that as one new version is released, the oldest version will be removed.
Please refer to our SDK Migration Guide in order to ensure that your application continues to function correctly after upgrading the SDK version.
