I am just the posting whore today. I setup newsbin today to use both US and Europe giganews servers both using port 443. When I loaded up an nzb I noticed this error in the logging tab...
[23:17:33] HIGH - SSL Unable to Add Zlib Compression
It's because the 64 bit code for SSL in that beta doesn't do zlib. It has no impact on downloading because none of the news servers use SSL Zlib any more. I already fixed it in a later beta. You won't notice a difference even with it fixed.
