We just released v0.3.0-alpha.1 of the source code. There are some relatively minor changes incoming between this and the relaunch but all the all the necessary features and bug fixes have now been merged. In crude summary:
- Fixes the undetectable inflation bug.
- Compresses transaction inputs, leading to greater on-chain throughput.
- Enables cold guessing.
- Changes proof-of-work puzzle to something memory-hard.
