Added in version 1.2.0: The lastDialStatus dictionary contains the last error (or null for success) for each peer address that Syncthing has attempted to contact. The connectionServiceStatus entries gained "error": null attributes where previously there would be no error attribute at all in the success case.

Added in version 1.18.0: The discoveryStatus dictionary lists all configured discovery methods, not only failed ones like the now deprecated discoveryErrors. Each entry is an object itself (for consistency with other fields), where a null value for the error attribute means the method is running successfully. This effectively deprecates the discoveryMethods attribute as well, which now always matches the number of entries in discoveryStatus.
