by default ssa, dsa and point multiplication are now sped up
using btclib_libsecp256k1; this provides an 8 times speed up
in benchmarks and 3 times in real world applications.

`v2022.5.3`

Compare Source

Major changes includes:

dropped python 3.6 support
added support for btclib_libsecp256k1
the hashes.fingerprint function, removed in the previous version,
has been reinstated in the to_pub_key module
encode_num and decode_num have been moved from script.op_codes to utils
op_pushdata and op_str have been renamed to
serialize_bytes_command and serialize_str_command
script.op_codes has been removed and its functions merged in script
script serialization is now more consistent: all integers, even small
ones, are now considered like bytes. To put small integers on the stack
OP_X must be used explicitly. Using integers directly will lead to larger
scripts that will be likely to be rejected by the network as not standard
check_validity is now correctly propagated inside each function

`v2022.2.9`

Compare Source

This is the latest release to support python 3.6

Major changes includes:

added bech32m
added Taproot support
introduced ScriptPubKey class
used script_type instead of prefix/wit_ver for b58/b32 address functions
split up op_int in op_num and op_int
prevented bip32 account derivation with arbitrarily high index
ensured der.Sig.r is congruent to a valid x-coordinate
renamed ScriptToken as Command
moved witness and script_pub_key into script folder
removed dataclasses_json dependency
introduced submodules
renamed Tx.tx_id as Tx.id
renamed deserialize as parse
renamed signature functions: trailing underscore marks hash-reduced versions
updated BIP32 test vectors
moved continuous testing from TravisCI to Github Actions
simplified configuration files
fixed pylint and flake8 warnings

`v2020.12.19`

Compare Source

Major changes includes:

added secp256k1 point multiplication based on efficient endomorphism
fixed ssa batch verification functions' logic
enforced snake_case variable naming convention,
e.g. 'script_pub_key', etc.
added BIP32KeyOrigin, BIP32KeyPath, and BIP32KeyPaths
adopted str instead of bytes as default type
for BIP32 keys, bms sigs, PSBTs, addresses, and WIFs;
base58 and bech32 encodings keep returning bytes, like base64
cleaned up and refactored all dataclasses,
now using serialize/deserialized and
possibly b58encode/b58decode, b64encode/b64decode, etc.
renamed TxIn.witness as TxIn.script_witness
fixed Witness management in TxIn and Tx, including equality operator
consolidated sig_hash code into sig_hash module
added more script_pub_key functions: assert_p2pkh, is_p2pkh, etc.

`v2020.11.23`

Compare Source

Major changes includes:

updated BIP340 (Schnorr signature) implementation
as per the latest changes in bitcoin core
refactored PsbtIn, PsbtOut, and Psbt
added legacy sighash
made btclib compatible with python 3.6
ssa.det_nonce now returns an int
moved tagged_hash from ssa into hashes module
added CurveGroup._y_aff_from_jac and removed unused methods
discontinued y_odd in favor of y_even as y-simmetry tiebreaker criterium
removed nonce input from dsa.sign and ssa.sign (only available from _sign functions)
cleaned up Exception handling, avoided bare/broad except
introduced btclib Exceptions that can be discriminated from regular Exceptions

`v2020.11.10`

Compare Source

Major changes includes:

removed TypedDict in favor of dataclass;
this also restored the ability of using btclib with python 3.7
introduced dataclasses_json as requirement, used to
serialize to file the json representation of dataclasses
Network is now a dataclass
bip32: BIP32KeyData is now a dataclass instead of dict, its data member
have to be accessed accordingly. Consequently, where previously it was
bip32.deserialize(xkey), now it is bip32.BIP32KeyData.deserialize(xkey)
bip32: added str_from_bip32_path and bytes_from_bip32_path
bip3: made bip32 index an int (not bytes) to avoid byteorder ambiguity.
Consequently, where previously it was xkey_dict["index"][0] < 0x80,
now it is xkey_dict.index < 0x80000000
bip32: local "./" derivation, opposed to absolute "m/" derivation,
is not available anymore
bip32: indexes_from_bip32_path now returns list[int] instead of
Tuple[list[bytes], bool] losing the "absolute derivation" bool
bms: serialize/deserialize have been renamed encode/decode as they
include the base64 (de)encoding, not jut the plain (de)serialization
Block: fixed bug in difficulty calculation
introduced first beta version of HdKeyPaths, PartialSigs, PsbtIn,
PsbtOut, and Psbt data classes and their associated helper functions
refactored Diffie-Hellman and ANSI-X9.63-KDF
introduced assorted elliptic curve point multiplication
algorithms
script: renamed Token as ScriptToken
script: encode/decode have been renamed as serialize/deserialize
as they were not encoding at all; the previous serialize/deserialize
which had varint(len()) before serialized data are not available anymore
alias: few definitions have moved in their relevant modules from which
they can be imported
pytest: enforced pytest > 6
pytest: using as many processes as the available CPU cores

`v2020.8.21`

Compare Source

Major changes includes:

added BlockHeader and Block data classes
added OutPoint, TxIn, TxOut, and TX data classes
added segwit_v0 sighash
added PsbtIn, PbstOut, and Psbt data classes for
partially signed bitcoin transactions (BIP174)
moved from unitest to pytest, including revision
of error messages and tests' logic
