0.4.1 (2017-11-01)

Removed blockr.io network backend as Coinbase has shut it down.

0.4.0 (2017-04-19)

Changed elliptic curve backend from OpenSSL to libsecp256k1. This results in an order of magnitude faster key creation and signing/verifying.
Improved performance of base58 encoding/decoding.
Breaking: Dropped support for Python 3.3 & 3.4.
Breaking: :func:`~bit.verify_sig` now returns False for invalid signatures instead of raising an exception. Also, strict is no longer a parameter as BIP-62 compliance is now required.

Fixed :ref:`cold storage <coldstorage>` workflow.
Improved performance of private key instantiation.

0.3.0 (2017-03-20)

Implemented a way to use private keys in :ref:`cold storage <coldstorage>`.
Changed the default timeout of services from 5 to 10 seconds.
Fixed network service redundancy by failing if response code is not 200.

Improved stability of network tests.
Added :func:`~bit.verify_sig`.
Refactored crypto to yield over an order of magnitude faster hashing.

0.1.0 (2017-03-15)

Initial release.
