List of notable changes made between 2.x and 3.0

All breaking changes must be described here. When adding a new entry, always describe the impact on users and instructions for upgrading applications from 2.x to 3.0.

boot.compile is now async and returns context with instructions

Users that uses boot.compile() in the following syntax would need to update their implementation, it now calls callback function with instructions in context object rather than synchronously returning instructions.

Before:

var APP_PATH = path.resolve('../sandbox');
var instructions = boot.compile(APP_PATH);

New signature:

var APP_PATH = path.resolve('../sandbox');
var instructions;
boot.compile(APP_PATH, function(err, context) {
  instructions = context.instructions;
});

Please see PR #181 for full details of change.
