[ZeroTier](https://www.zerotier.com) SDK
=====
Connect physical devices, virtual devices, and application instances as if everything is on a single LAN.
ZeroTier brings your network into user-space. We've paired our network hypervisor core with a TCP/UDP/IP stack [(lwIP)](https://en.wikipedia.org/wiki/LwIP) to provide your application with an exclusive and private virtual network interface. All traffic on this interface is end-to-end encrypted between each peer and we provide an easy-to-use socket interface similar to [Berkeley Sockets](https://en.wikipedia.org/wiki/Berkeley_sockets). Since we aren't using the kernel's IP stack that means no drivers, no root, and no host configuration requirements.

## 1.3.3-alpha.2 Release Notes
### New namespace structure:
- `ZeroTier.Core` (API to control a ZeroTier Node)
- `class ZeroTier.Core.Node`
- `class ZeroTier.Core.Event`
- `ZeroTier.Sockets`
- `class ZeroTier.Sockets.Socket`
- `class ZeroTier.Sockets.SocketException`
- `ZeroTier.Central` (upcoming)
### Added to Socket API
- `Socket.ReceiveTimeout`, `Socket.SendTimeout`, etc.
### Bugs
- Fixed memory leak caused by unmanaged resources not being released.
