v0.15.2

This release fixes a panic in the gRPC SubscribeTransactionStream method. If you are using this method or if you are running a public (unauthenticated) gRPC server we highly recommend upgrading to avoid having your node crash on you.

Additionally some improvements to peer connectivity are included in this release which makes connections more stable.

Lastly you can now whitelist or blacklist certain user agents when finding peers.
