We are delighted to announce the next major Golem release that consists of changes in the protocol, the core and the GUI. The main improvements are: an uPnP support (which means no need for a port forwarding anymore if supported by a router), GNTW migration (testnet will now work with a contract that is based on real GNT contract with additional wrapper layer added) and a modern-style Windows installer.

As usual we encourage you to follow the progress of our project on Golem Kanban, download and test the newest release, as well as provide us with feedback, so that we can keep improving Golem. For more details and troubleshooting, please visit the official GitHub repository.

Because of this migration your testnet balance will be zeroed and later refill with the new test GNT.
