DOM backward compatibility
This page is used to track changes to the DOM API.
Purpose
Sometimes the DOM API will be changed in a way that client applications won't work properly when they upgrade to the latest version of the DOM. Although the DOM maintainers will minimize API breakage as much as possible, sometimes it's necessary. In most API breakage situations, the client application will no longer compile. This page is used to record any changes that require clients to modify their code to work with a newer version of the DOM.
Core API changes
This section tracks changes made to the core API.
IO plugin changes
