For Package Developers

• You can now have a urlMain in your package.json which will be used as the bootstrap script for all urls opened with your package name as the host, such as atom://collaboration/12345.
• You can now add menu items to global menus by specifying the appropriate information in cson menu files included in your menus directory like so:

'menu': [
  {
    'label': 'View'
    'submenu': [
      {
        'label': 'Toggle Treeview'
        'command': 'tree-view:toggle'
      }
    ]
  }
]

• Upgraded jQuery to 2.0.3
• If you're currently using {_} = require 'atom' and then calling _.nextTick you should use node's setImmediate instead.
• Packages are now hosted on atom.io so you'll need to remove the publishConfig key from your package.json and replace it with "private": true (which is a precaution to prevent packages from accidentally being published to npmjs.org).
