Yes. Finally. After a year of development, 1.8 has finally gone stable. The main major feature added is Teredo (see General preferences) and IPv6 support, but there’s a slew of smaller features, changes and improvements. The changelog is absolutely massive, so check it out down below.

It was also announced that there will be a Mac version soon!
That’s cool! Hope it is gonna get as good as the Windows version.
Let’s hope people start using Teredo/IPv6 feature, it can help with NAT alot.
