We just posted updated terms of service for 5 more APIs to include
transparent deprecation policies. This is part of their increased commitment as graduates of
Google Code Labs. As we mentioned in
March when we introduced
Labs, each of these deprecation policies states that we'll support each version of
the API for a guaranteed length of time from when it's deprecated or a newer version is
introduced. While it's 3 years for most, it might be less for some. With this batch of
updates, for example, the Checkout API has a policy of supporting old versions for 1 year
while all of the others will support old versions for 3 years.
