From their site: The Google Gadgets API provides a way to put third-party content onto the Google homepage. The main use of the Google Gadgets API is to create gadgets (mini-applications) that users can add to their Google personalized homepages and other Google properties. For example, you could create a photo album gadget, or a gadget that displays an interactive game. The API is designed to be simple enough so that anyone can turn his or her web page or application into a gadget.
The following is a list of historical changes that were made to this asset. Typically,
once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change.
As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset,
we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all
activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb.
If you spot an error in our data and believe that a record needs to be updated in some way,
