paradox-execute-asynchronously variable

Set to t or nil depending on whether you want this feature.

paradox-upgrade-packages command

Upgrade everything, wherever you are. Combines well with the above.

paradox-after-execute-functions variable

A hook run after every transaction. Remove functions from it to streamline your experience, or add your own functions to extend functionality. For instance, if you don't like the new *Paradox Report* buffer, you can prevent its creation by removing the relevant functions from the hook:

(remove-hook 'paradox-after-execute-functions
  #'paradox--report-buffer-print)

Better interaction

Now, when you hit x in the Paradox Menu to execute a set of installations and deletions, the buffer narrows to display only those packages (see below). Much nicer than the usual message in the echo area.

These are the main changes. You can also view package commit lists, but that's been the case for a while.
