**Full Changelog**: https://github.com/CityOfZion/neo-mamba/compare/v1.0.0...v2.0.0

This release adds support for 2 new opcodes (`PUSHT` and `PUSHF`). Aside from that the Python version is pinned and the `pip` installation instructions are corrected.

A new beginning. This release is a massive one as the project pivots from full node to light SDK. Check out the [medium article](https://medium.com/lllwvlvwlll/8e08e9082f6a) for more information like why we pivoted.

This release brings back full OSX support. The implementation of a security feature in the virtual machine (`neo3vm`) was changd that results in a simplified external interface used in mamba. This release also adds 2 light wallet style CLI examples to deploy a smart contract and send NEP-17 tokens.

This release updates the existing components to be NEO `v3.2.1` compatible. It also includes two fixes a result of auditing the N3 Testnet. Mainnet has been audited up to block `1449548` with no state differences.
