This is a major release with several API changes and an update to use Bitcoin v0.12.0 and requires a database reindex. Bitcore now starts bitcoind as a child process and communicates via ZMQ/RPC, address indexes are now built and queried from Bitcoin directly using a branch with additional indexing options added, more information is at: https://bitcore.io/bitcoin

This is a major release without any breaking API changes, however there are significant changes to the organization of modules.

npm install -g bitcore
bitcored
