Information from Google about ‘L release’ and ‘Material Design’

Today (June 25th) Google previewed what will be the next Android version.

Calling it ‘L Preview’ and ‘L release’, this is so far “just” a preview and not at all the final product. HTC have made statements that they will update to ‘L Release’, “within 90 days after release of final software”. What Google showed today is NOT the final software, but merely a Preview of what they’re working on.
