VC 7.0 Vs 7.1

Hi All,

1) Can anyone let me know the differences between VC 7.0 and 7.1?

2) IF there are 2 URLs  http://<servername>:<portnumber>/VC/default.jsp     

                                     http ://<servername>:<portnumber>/ VC/freestyle.jsp

can we determine the version of the VC just by looking the URLs? and what is the meaning of "default" and "freestyle" in the above links?

3) What are the prequesites for developing applications in VC and run them in EP?

4) when we installed EP,VC will be automatically installed or anyother settings/installations are needed?

Your Help would be much appreciated.

Thanks,

Salma
