You can use it to specify that a resource should only be available on one platform. #### Known Issues The timeline will not work if you have Python 2.7.8+. Please use Python 2.7.6 if you want to work with the new timeline APIs. ### Changes for Examples: Examples have been removed from the SDK download, and our old examples repository has been deprecated. You can now find all our examples on [pebble-examples on GitHub]({{site.links.examples_org}}/). ### Changes for Documentation: *No changes*
