// APIExtensions is the list of all API extensions in the order they were added.
//
// The following kind of changes come with a new extensions:
//
// - New configuration key
// - New valid values for a configuration key
// - New REST API endpoint
// - New argument inside an existing REST API call
// - New HTTPs authentication mechanisms or protocols
//
// This list is used mainly by the LXD server code, but it's in the shared
// package as well for reference.
