Peercoin client v0.8.0~RC1 has been released for testing today. This next-generation client is based upon bitcoin-core 0.16.3 with several cherry-picks from bitcoin-core 0.17.1.
The new client is segwit-ready but segwit is not activated yet. For the moment the client implements v0.7 Peercoin protocol and is fully compatible with the testnet network.
Join us in testing efforts. The faster we iron out the bugs, the faster this will be launched on the mainnet.
