Homebrew will automatically download the latest version of a piece of software. For my homework to install "Hive", I have to try a specific version of 'Hive' (version 1.2.1), so I'll search how to install a older version of 'Hive', and here are the results:

$ brew tap Homebrew/versions

Then search for desired packages, for me it would be 'hive'

$ brew search hive

This gives me the result: 

homebrew/versions/hive12

Finally I install that version

$ brew install homebrew/versions/hive12

And that's how is done!
