Major change: cleaned up what symbols are exported by modules. all is now used extensively, which may break some applications that were not importing the right modules. Along those lines some implementation details like the ssl attribute of the bitcoin.core.key module, and the entire bitcoin.core.bignum module, are no longer part of the public API. This should not affect too many users, but it will break some code.
Other notable changes:
- New getreceivedbyaddress RPC call.
- Fixed getbalance RPC call when wallet is configured off.
- Various code cleanups and minor bug fixes.
- Improve bitcoin address handling. P2SH and P2PKH addresses now get their own classes - P2SHBitcoinAddress and P2PKHBitcoinAddress respectively - and P2PKH can now convert scriptPubKeys containing non-canonical pushes as well as bare checksig to addresses.
- .deserialize() methods now fail if there is extra data left over.
- Various other small bugfixes.
- License is now LGPL v3 or later.
Major change: CTransaction, CBlock, etc. now come in immutable (default) and mutable forms. In most cases mutable and immutable can be used interchangeably; when that is not possible methods are provided to create new (im)mutable objects from (im)mutable ones efficiently.
Other changes:
- New BIP70 payment protocol example. (Derren Desouza)
- Rework of message serialization. Note that this may not represent the final form of P2P support, which is still in flux. (Florian Schmaus)
- Various bugfixes
Finally starting this release, git tags will be of the form 'python-bitcoinlib-(version)', replacing the less specific '(version)' form previously used.
