• Now the dmsgpty-ui terminal from the /pty route of the hypervisor is used when accessing the manager with an http URL, due to problems with https. When using a https url for opening the manager, the old terminal, which works with the /visors/{pk}/exec API endpoint, is used.

• Part of the code for error management of the desktop wallet was adapted and added to the manager, as previously the manager was depending a lot on assumptions which were not really good for displaying accurate error messages. Some parts are now showing the error messages using the new information obtained with the new procedures, for giving more accurate information in cases in which it is needed (like when the updater fails), and other parts were not changed, to avoid making too many changes with potential errors before the release.

• Various small bugs were fixed.
