[Spread-users] 4.2 IP Multicast issues

[Jonathan Stanton]

Thanks for the report. There were some subtle changes in datalink's handling of multicast. I found one bug and fixed it before the rc2 version, but it looks like you found another regression. 

I'll try a test config like yours and see if I can duplicate the problem.

Cheers,

Jonathan
