When the Pebble SDK major version is increased (such as from 2.x to 3.x), some
breaking API and build process changes are made. This means that some apps
written for an older SDK may no longer compile with the newer one.

To help developers transition their code, these guides detail the specific
changes they should look out for and highlighting the changes to APIs they may
have previously been using. When breaking changes are made in the future, new
guides will be added here to help developers make the required changes.
