v1.0.0

This is a major release without any breaking API changes, however there are significant changes to the organization of modules. All of the core library functionality has been moved to bitcore-lib, and bitcore is now a metapackage that includes bitcore-lib, bitcore-node, insight-api and insight-ui. Two new executables, bitcore and bitcored, can now be installed in your path globally to run a full node and block explorer in two commands:

npm install -g bitcore
bitcored

v0.13.0

This is a minor release and includes a significant API change relating to the standard methods toJSON/fromJSON. When updating it's important to note that toJSON is now compatible with JSON.stringify and will work as expected and calling JSON.stringify on any Bitcore object, and toJSON called directly will not return a string. The method fromJSON has be replaced with fromObject and JSON is expected to be parsed prior to instantiating a Bitcore object, see #1312 for the full details.

There have been a number of bug fixes and performance improvements since the v0.12.0 release. Block parsing should be around 30 times faster, including other performance improvements related to recognizing script types in support of bitcore-node.
