+Generates typings for contracts compatible with latest Web3.js version. It requires official typings from `@types/web3` installed. For now it needs explicit cast as shown [here](https://github.com/krzkaczor/TypeChain/pull/88/files#diff-540a9b8840419be93ddb8d4b53325637R8), this will be fixed after improving official typings.

+### Legacy (Web3 0.2.x)
 
 This was default and only target for typechain 0.2.x. It requires `Web3.js 0.20.x` to be installed in your project and it generates promise based wrappers. It's nice upgrade comparing to raw callbacks but in the near future Typechain will support `Web3js 1.0` target.
