While the overall APIs are not in labs, there is one recent feature that is still experimental: AIR support in the Maps API for Flash. From time to time, as we release new features that are more of an experimental nature, we may let them bake in labs for some time. As with Google Labs and Google Code Labs, we'd like to get early feedback and see how you use these experimental features before making a long term commitment to them.
As always, please continue sending your feedback in the appropriate forum:
We've also set up "notify" groups that you can sign up for if you just want to see the important updates, e.g. new releases. You can sign up from the home page of each API or use the links below:
