Known Zimlet compatability issues with Zimbra 5?

[Vimm]

Are there any known Zimlet compatibility issues with Zimbra 5? I'm trying to use a custom Zimlet that worked with 4.5 but it doesn't seem to do anything when installed on 5.0 RC2. Are there any known changes or issues that might prevent my Zimlet from working?

[jholder]

Yeah, there are.
We'll have more information as we get closer to the release date.

For example, if you deploy the 4.5 RSS zimlet on ZCS 5.0, it will break other zimlets

Thanks, that's good to know. Do you happen to know if Zimbra 5's still scheduled for the 17th?
