Version mismatch on Github and CRAN

[lucazav]

The latest release I can see here on Github is 0.3.0. On CRAN I can see the 0.5.0 right now.
Why this mismatch? How can I see the changes made to version 0.5.0?

I will move this to discussion since it's not a bug report.

They are out of sync. Let me check how others do it.
