* In a previous update in 2021 many copyright ranges were truncated
accidentally, and some files have been copy-pasted with wrong years. These
dates have been fixed based on git history and original copyright messages.
In some cases it is easier to know the dispatch thread ID you want to
debug rather than the group/thread IDs. This change adds a new window
when the debug button is clicked, to allow you to specify which thread
to debug in the most convenient way.
