Better display for Link/Multilink and content Link/Multilink are now displayed as a dictionary by default. The format is controlled by the setting of the @verbose option. With @verbose=0 we get the old behavior displaying only the id. With the default @verbose=1 we get a dictionary with the id and a link inside. With @verbose=2 or larger we get the label property in the dictionary in addition (e.g. the name of a status or the name of a file). The content property is also handled differently now. For @verbose < 2 we get a dictionary with a link property in it. The property points to the standard download link for the content (or message). For @verbose >= 2 we get the previous behavior, the content property as a possibly very large json string.
