When do I need to generate new API keys for CardControl SDK?

After updating CardControl SDK, users may need to generate new API keys.

An easy way to tell if you will need to generate new API keys is to look at the version numbers of CardControl SDK. If the second number in the version number is different from your current version, new API keys will need to be generated. For example, if you upgrade from version 2.0.0 to version 2.1.0.
