• Significant API overhaul:
  • Remove nu_select macro and low-level networking support

0.14.1 - 2018-08-28

• Reject non-compact VarInts on various types
• Expose many types at the top level of the crate
• Add Ord, PartialOrd impls for Script

0.14.0 - 2018-08-22

• Add regtest network to Network enum
• Add Script::is_op_return() which is more specific than Script::is_provably_unspendable()
• Update to bech32 0.8.0; add Regtest bech32 address support
• Replace rustc-serialize dependency with hex as a stopgap toward eliminating any extra dependencies for this; clean up the many independent hex encoders and decoders throughout the codebase.
• Add conversions between ChildNumber and u32; make representation non-public; fix documentation
• Add several derivation convenience to bip32 extended keys
• Make deserialize::deserialize() enforce no trailing bytes
• Replace TxOutRef with OutPoint; use it in TxIn struct.
• Use modern as_ to_ into_ conventions for array-wrapping types; impl Display rather than ToString for most types
• Change script::Instructions iterator to allow rejecting non-minimal pushes; fix bug where errors would iterate forever.
• Overhaul util::Error; introduce serialize::Error and use it for SimpleDecoder and SimpleDecoder rather than parameterizing these over their error type.
• Overhaul UDecimal and Decimal serialization and parsing and fix many lingering parsing bugs
• Update to serde 1.0 and strason 0.4
• Update to secp256k1 0.11.0

0.13.1

• Add Display trait to uints, FromStr trait to Network enum
• Add witness inv types to inv enum, constants for Bitcoin regtest network, is_coin_base accessor for tx inputs
• Expose merkleroot(Vec<Sha256dHash>)

0.13

• Move witnesses inside the TxIn structure
• Add Transaction::get_weight()
• Update bip143 sighash_all API to be more ergonomic

0.12

• The in-memory blockchain was moved into a dedicated project rust-bitcoin-chain.
• Removed old script interpreter
• A new optional feature "bitcoinconsensus" lets this library use Bitcoin Core's native script verifier, wrappend into Rust by the rust-bitcoinconsenus project. See Transaction::verify and Script::verify methods.

• Un-reversed the Debug output for Sha256dHash
• Add bech32 support

0.11

• Remove num dependency at Matt's request; agree this is obnoxious to require all downstream users to also have a num dependency just so they can use Uint256::from_u64.
