If you invested in the Pebble e-paper smartwatch -- and who didn't? -- you'll be happy to hear that the firm has unleashed a preview of the Kickstarter darling's SDK at Google I/O this week.

The company said the new kit supports multiple program languages to boot, allowing developers of all skill levels to create Pebble-enabled apps. The document is still a work in progress, of course, but advances like this should help keep it from getting trampled by the cavalcade of smart wrist devices now coming out.
