4.0

This is a breaking release.

Drop support for Python 3.7.
Support Coincurve up to version 20.
Drop base58 dependency. Port base58 code directly in-tree as a base58 module.
Fix circular dependency in source installation.
A new method get_fingerprint() was added.

3.4

Support Coincurve up to version 18. This version includes support for BIP340 x-only keys and Schnorr signatures.

3.3

Implement a pure Python fallback for RIPEMD160 in case hashlib does not provide it. NOTE: the Python implementation was copied from a test-only implementation and is not constant time. This shouldn't be an issue for the usage we make of it here.

3.1

Actually support Coincurve up to version 17..

3.0

This is a breaking release.

Python 3.10 support.
Drop Python 3.6 support (EOL).
Support Coincurve up to version 17.

2.1

Two new methods were added: get_xpub_bytes() and get_xpriv_bytes()

2.0

This is a breaking release.

Added test vector #5 for more sanity checks when deserializing an xpub or an xpriv (see bitcoin/bips#921).
Renamed get_master_xpub and get_master_xpriv to get_xpub and get_xpriv.
We now refuse to create a BIP32 object with:
- An unknown network
- A depth of 0 (master) and a non-0 index or fingerprint

1.0

Added test vector #4 for private keys with leading zeros (see bitcoin/bips#1030)
(Breaking) Bumped Coincurve dependency to 0.15
Re-arranged the 2 dependencies to use "compatible release" notation

0.1

Started to use a changelog
New InvalidInputError raised instead of bluntly asserting on insane inputs
New PrivateDerivationError raised when trying to access private keys without private keys being set (eg for hardened derivation).
Bugfix: we can now parse "master paths": ie do pubkey_from_path("m") or pubkey_from_path([])
