Upgrade COPS to 1.0.0RC1

I have tested it on DSM 4.1 but cannot test on DSM 5.

Is there something specific to do to make it work with DSM 5 ?

To explain a little more COPS is using an external directory (/volume1/calibre for example) I've heard that I have to change the owner of that directory and maybe add some rights (I only need to read from this directory).

Thanks in advance.
