Changes (as compared to beta 2) include:
* Register/Edit server page now has tabbed interface which eases navigation.
* Monitor/Dashboard charts can now be exported to an image file (pdf, jpeg or png). This was disabled in the 5.0 betas but is now functional again.
* MONyog was not sending email alerts if the 'SMTP encryption type' was set to 'No Encryption'. This bug was introduced in 5.0 beta 2.
Additionally lots of UI issues and usability issues with the new interface were fixed. We are not aware of any such issues with this RC release and expect to go GA soon. Please report issues soon if you encounter any.
