-0.9.0
-	* don't force "Path Abs" anymore in IO module, abstract more over Path types
-	* add 'toAbs'
-0.8.1
-	* add 'readFile', 'readFileEOF', 'writeFile' and 'appendFile'
 0.8.0
 	* 'copyDirRecursiveOverwrite', 'copyFileOverwrite', 'easyCopyOverwrite' and 'moveFileOverwrite' have been removed, instead use the versions without the *Overwrite suffix and pass in 'Strict' (for default behavior) or 'Overwrite' as the CopyMode argument
 	* introduced a new 'RecursiveErrorMode' type to allow controlling recursive behavior of 'copyDirRecursive' (use 'FailEarly' for default behavior)
