Thanks updated my .conf file.
still stuck on block 314336. hope to get upto date I do solo mining on GPU along with BlakeCoin. Blake is algo not Bake's 7 sci FI
I only have 2 peers but both are 2.5.6
The second one is mine (a linux machine), compiled 2.5.6 from source:
git clone https://github.com/scificrypto/Federation-Credits.git
cd Federation-Credits
git checkout master
So 2.5.6 is the latest version, yes. Again, as far as I remember, this was just an UI color/theme change.
The latest compiled Windows version I can find is 2.5.5 from the google drive link above, have it running on a Windows machine. Both working fine together since... forever.

There was a compiled 2.5.6 version for Windows available on the scificointalk-forum, but can't find any reference to this one anymore, sorry.
Just checked the node and have at the moment three 2.5.6 and three 2.5.5 peers.
Here you have their IPs, but guess some of them will not allow inbound connections:
addnode=99.192.82.190
addnode=64.71.72.56
addnode=142.68.146.143
addnode=2.94.237.180
addnode=45.50.28.121
addnode=119.123.48.54
