 ### IMPROVED ###
 * ImgCache.getCachedFileURL: error callback is now optional (#79)
 * Cache directory is no more backed up in iCloud (iOS) (#73)
+* Added ability to override the hash method through ImgCache.overridables.hash, SHA-1 currently being the default. It's possible to plug in a faster alternative but be careful of possible collisions (#81)
+* The log method used throughout ImgCache is now defined as an overridable option: ImgCache.overridables.log -- this replaces the previous 'customLogger' optional method (read Backward Compability Warning below)
+* Fixed some JSLint issues
+
+### BC WARNING ###
+* ImgCache.options.customLogger has been changed to ImgCache.overridables.log

 Options can be overridden from your own script, no need to modify the library!
 
+Overridable methods
+-------------------
+* The hash method used by default in ImgCache is SHA-1. It was chosen for its near absence of collision. Though it might slow things down if you have a large number of files to cache (see #81). You can plug-in your own method by overriding ImgCache.overridables.hash.
+* If logging is enabled, ImgCache output some log entries in the console by default. You can override ImgCache.overridables.log in order to change this behaviour.
