You may have heard about [Pebble Time Round](https://rePebble.com/timeround), our newest addition to the Pebble family which adds a whole bunch of new possibilities, challenges, and opportunities for our dedicated developers to get creative with.

With a new platform usually comes a new SDK to play with. Well, why wait? All developers can now get their hands on the new [SDK 3.6-dp2](https://developer.repebble.com/sdk.md) or use it on [CloudPebble](https://cloudpebble.repebble.com/). This is a preview of the first Pebble Time Round-compatible SDK, allowing developers to realize their ideas for new and improved watchapps and watchfaces. Have a favorite classic round watchface that looks cumbersome on a rectangular display? Try it out on this one!

## New Resources

To get you started, we have updated many sections of the Pebble Developer site with new content and information on designing and developing for the new Pebble hardware platform, code-named Chalk. Read more on the [_Getting Started with Pebble Time Round_](https://developer.repebble.com/sdk/round-getting-started) page.

## Virtual Lab

Want help getting started with the Pebble Time Round SDK? Join us on September 24th at 1pm PDT in our Slack channel for a virtual lab with the Pebble Dev team. Bring all your questions, and we'll do our best to answer them!

## Compatiblity Note

Bear in mind, this is a **developer preview** , meaning that apps created with this SDK should **not** be uploaded to the Pebble appstore, as it is subject to possible breaking changes in new APIs before the final release of SDK 3.6. Thanks for your cooperation!
