What happens when upgrading to VB 3.0.3

[globalstrata]

Ok. I know that if fixes bugs and add some functionality. But what really happens with the hacks? :ermm: For example, I have installed VBAdvanced CMPS, VBArcade and few other minor hacks supported under VBAdvanced CMPS such as the weather, donation and few other modules.

each hack have to be re-installed, because when you upgrade you replace all the files and templates that were to be updated...
