This means that Frontier, the first release of Ethereum, is only a few weeks away. In order to put the network through its paces, we are offering prizes (for a total of 25K ether) for a variety of challenges.
You can download the software at:https://github.com/ethereum/go-ethereum/releases/tag/v0.9.18
