* [Remove `Address::p2pk`](https://github.com/rust-bitcoin/rust-bitcoin/pull/222/)

* Finally merge [PSBT](https://github.com/rust-bitcoin/rust-bitcoin/pull/103) after nearly nine months

# 0.16.0 - 2019-01-15

* Reorganize opcode types to eliminate unsafe code
* Un-expose some macros that were unintentionally exported
* Update rust-secp256k1 dependency to 0.12
* Remove `util::iter::Pair` type which does not belong in this library
* Minor bugfixes and optimizations

# 0.15.1 - 2018-11-08

* [Detect p2pk addresses with compressed keys](https://github.com/rust-bitcoin/rust-bitcoin/pull/189)

# 0.15.0 - 2018-11-03

* [Significant API overhaul](https://github.com/rust-bitcoin/rust-bitcoin/pull/156):
    * Remove `nu_select` macro and low-level networking support
    * Move `network::consensus_params` to `consensus::params`
    * Move many other things into `consensus::params`
    * Move `BitcoinHash` from `network::serialize` to `util::hash`; remove impl for `Vec<u8>`
    * Rename/restructure error types
    * Rename `Consensus{De,En}coder` to `consensus::{De,En}coder`
    * Replace `Raw{De,En}coder` with blanket impls of `consensus::{De,En}coder` on `io::Read` and `io::Write`
    * make `serialize` and `serialize_hex` infallible
* Make 0-input transaction de/serialization [always use segwit](https://github.com/rust-bitcoin/rust-bitcoin/pull/153)
* Implement `FromStr` and `Display` for many more types

# 0.14.2 - 2018-09-11

* Add serde support for `Address`

# 0.14.1 - 2018-08-28

* Reject non-compact `VarInt`s 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](https://github.com/rust-bitcoin/rust-bitcoin/pull/84) to `Network` enum
* Add [`Script::is_op_return()`](https://github.com/rust-bitcoin/rust-bitcoin/pull/101/) which is more specific than
  `Script::is_provably_unspendable()`
* Update to bech32 0.8.0; [add Regtest bech32 address support](https://github.com/rust-bitcoin/rust-bitcoin/pull/110)
* [Replace rustc-serialize dependency with hex](https://github.com/rust-bitcoin/rust-bitcoin/pull/107) 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`](https://github.com/rust-bitcoin/rust-bitcoin/pull/126); make
  representation non-public; fix documentation
* [Add several derivation convenience](https://github.com/rust-bitcoin/rust-bitcoin/pull/129) to `bip32` extended keys
* Make `deserialize::deserialize()` [enforce no trailing bytes](https://github.com/rust-bitcoin/rust-bitcoin/pull/129)
* 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](https://github.com/rust-bitcoin/rust-bitcoin/pull/136);
  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](https://github.com/rust-bitcoin/rust-bitcoin/pull/137).
* Overhaul `UDecimal` and `Decimal` serialization and parsing [and fix many lingering parsing bugs](https://github.com/rust-bitcoin/rust-bitcoin/pull/142)
* [Update to serde 1.0 and strason 0.4](https://github.com/rust-bitcoin/rust-bitcoin/pull/125)
* Update to secp256k1 0.11.0
* Many, many documentation and test improvements.

# 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.
* Replaced Base58 traits with `encode_slice`, `check_encode_slice`, from and `from_check` functions in the base58 module.
* Un-reversed the Debug output for Sha256dHash
* Add bech32 support
* Support segwit address types

### 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`.
