Pebble SDK 2.0 is currently in BETA and intended for developers only.
SDK 2.0 will be released early next year as an over-the-air update to all Pebble users.
Applications written for Pebble 1.x are not compatible with SDK 2.0
If a 2.0 version of an application exists, the Pebble mobile applications will automatically install it when when a user upgrades her/his Pebble.
You can start uploading your application to the Pebble appstore TODAY - Please do so!
