@facuspagnuolo facuspagnuolo released this Jan 10, 2019 · 180 commits to master since this release

The main feature of this release is support for contract compilation with both Truffle 4 and Truffle 5. This means that you can now use ZeppelinOS with contracts built using Solidity 0.5.x. We have also adapted the Initializable contract to be compilable with both Solidity 0.4 and 0.5. However, under the hood, ZeppelinOS still depends on Truffle 4 and Web3 0.x; we are working to migrate the entire stack to Web3 1.0 in an upcoming release.

This release also includes automatic gas price setting when working on mainnet, by querying ethgasstation to obtain an average gas price value. Thanks @zachzundel for the contribution!

Last but not least, after etherscan opened up their API for contract code verification, we are also including automatic contract verification on etherscan via the zos verify command. Thanks @ProtonGustave for the contribution!
