Importing
BaseCommand
orMultiCommand
fromclick
orclick.core
will show a deprecation warning. They subclassCommand
andGroup
, andisinstance
andissubclass
will still work.CommandCollection
still exists, but since it subclassesGroup
now it also supports commands on the group itself as well as the other sources.Tests were trivial to update, and nothing failed in the switch. Docs were updated to always use the term "group" instead of "multi command", and some other cleanup was done.
