I use the tool asdf to install my tool versions

They changed the command to set the local and global versions.

It doesn't say "syntax changed to blah", that would be too easy. Just prints the same help it does when you just type the command with no args.

This has bitten me a couple of times on different machines, as I use the shell history - I hate typing things in over and over again.

Your tool, you change it, fine. Give folks a tiny bit of a hand when they use changed commands?
