Release History

Unreleased (see master)

0.6.2 (2020-07-10)

Fix of critical bug that could lead to paying high fees (see PR #116)
Better fee calculation by estimating transaction sizes for multisig correctly
Lots of Network API improvements: Removed deprecated Bitpay API and added Blockstream, Blockchair and Bitcore.

0.6.1 (2020-02-16)

Fixed Smartbit polling transaction hashes instead of ids
Add support for passing raw hexadecimal messages to send

0.6.0 (2019-09-04)

Added support for NetworkAPI to use a remote Bitcoin node
Fixed usage of BitPay rates API (it was changed abruptly)

0.5.2 (2019-05-16)

Fixed a subtle bug when signing a multisig transaction over multiple inputs

0.5.1 (2019-04-19)

New: Add get_transaction_by_id() calls
Update default fees
Multisig improvements

0.5.0 (2019-03-10)

New :class:`~bit.MultiSig` adds support for P2SH nested m-of-n multisignature contracts
Support for sending to P2SH and Bech32 output addresses
P2SH nested segwit addresses for :class:`~bit.PrivateKey` and :class:`~bit.MultiSig`
Support for batching transaction inputs from different keys
Update transaction message length limit to 80

0.4.3 (2018-03-11)

Fixed fee calculation when combine=False
Breaking: Exceptions will now be raised when using pay2sh addresses (until implemented)

0.4.2 (2017-12-09)

Optimized network API priorities
Fixed Smartbit pushtx usage
Updated 21.co to earn.com

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.

0.3.1 (2017-03-21)

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.

0.2.0 (2017-03-17)

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.
