The purpose of this release is to split ConseilJS into several parts to minimize the number of direct dependencies. ConseilJS is packaged as three components: ConseilJS-core, ConseilJS-softsigner and ConseilJS-ledgersigner.

Breaking Changes

New interfaces were introduced to support external signing and key storage: KeyStore, Signer.
Any function that previously took a required KeyStore-type parameter now also requires a Signer. This includes many changes in TezosNodeWriter, TezosOperationQueue, and the contract wrappers in src/chain/tezos/contracts/.
CryptoUtils has moved to ConseilJS-softsigner. This removes dependencies on crypto, libsodium and others.
What used to be in src/identity/tezos/ is not split between the ConseilJS-softsigner and ConseilJS-ledgersigner packages.
CryptoUtils.simpleHash was moved to TezosMessageUtil.simpleHash, smae with twoByteHex, fromByteHex
