We get asked this question a lot.
The general answer is that we don’t like to rush releases. We want to make sure that the SDK that we give you has been tested and that we are happy with what we are releasing.
Sometimes our releases contain new features, whilst at other times we improve the existing APIs to make them a little more bug free, or improve the documentation so that you have all the information that you need at your fingertips.
Whenever we push a release to the public, we try to add the internal ticket number that the release note touches upon, to let our customers know which features have been added or bugs have been fixed.
