v2.5.1 - Petersburg fork & More! ⋔

The Petersburg hardfork is scheduled to go live on mainnet on block number 7,280,000, estimated to occur on February 28th. This hardfork removes the reentrancy attack vector introduced in the Constantinople hardfork (which also goes live on mainnet on block 7,280,000). This release includes ethereumjs-vm@2.6.0 which includes support for the Petersburg hardfork. Also: bug fixes!
