 1.0.4.4
 	* Either replaced instances of '(<$>)' with 'fmap' to avoid ambiguity between "Control.Applicative" & "Prelude" which (from 'base-4.8') also exports this symbol, or hid the symbol when importing the "Prelude"..
 	* In module "Main", redirected version-message to stderr.
+1.0.4.5
+	* Added the compiler to the output returned for the command-line option "version".

 We can improve on that result if we're prepared to split some of the artist-specific directories into individual albums.
