While `clippy` now allows `TBD` to be used in `since` parameter of
`deprecated` attribute it is only available in the newest, nightly,

TxOut::minimal_non_dust has 3 problems.
1. There is an invisible dependency on Bitcoin Core's default minrelaytxfee value. It has been made explicit.
2. There is an off by one error. The dust limit comparison uses < and therefore `+ 1` was not needed. It has been fixed.
3. It was not returning 0 amount for OP_RETURN outputs.
Script::dust_value has 2 problems.
1. The dust amount depends on minrelaytxfee which is configurable in Bitcoin Core. This method was not configurable.
2. The division operation was done before multiplying the byte amount, which can cause small differences when using uncommon scripts and minrelaytxfee values.
In the 0.31.0 release we renamed the bip32 extended key types without
leaving the originals in there marked as deprecated. This makes for a
bad experience for devs, add them back in.

Add a feature matrix section to the `bitcoin` CI script as we do in
`hashes`. This means:
- test with no default features
- test with all individual features
- test with all combinations of two features
Note, with this applied all features and optional dependencies are
included in `FEATURES` (excluding `secp-lowmemory`).
The feature matrix test gets run for stable and MSRV toolchains.
Currently `bitcoin` cannot be built with no features enabled, it must
have either "no-std" or "std" enabled. This is an artifact from when
we depended on `core2` for "no-std", now that we have our own `io` crate
and we unconditionally depend on it we can remove the "no-std" feature.
We are emptying the `hash_types` module. `impl_asref_push_bytes!` is an
internal macro, as such it can live in the `internal_macros` module.
While we are at it import the macro and call it without any qualifying
path, this is typical for our usage of other internals/internal_macros
usage.
We would like all the various hash types to be defined where they
rightly live instead of in the `hash_types` module.
Move the BIP-158 filter hash types to the `bip158` module.
We would like all the various hash types to be defined where they
rightly live instead of in the `hash_types` module.
Move transaction hash types to the `transaction` module.
We would like all the various hash types to be defined where they

Move the block hash types to the `block` module. While moving, add full
stops to the rustdoc of each hash.
Re-export _all four_ types from lib.rs (previously `WitnessMerkleNode`
was not re-exported).
An `AddressInner` struct is created when parsing address strings however
address strings do not map 1:1 to `Network` because signet and testnet
use the same bech32 prefix "tb".
We can fix this by inlining the `Payload` variants into `AddressInner`
and adding prefix enums for legacy addresses and a `KnownHrp` for bech32
addresses.
Also enables removing the `AddressEncoding` struct as we can display the
`AddressInner` struct directly. (The `Display` impl is on `AddressInner`
and not directly on address to ignore the `NetworkValidation` wrapper,
may be able to be simplified still further.)
Calling `wpubkey_hash` on a key that is uncompressed is flat out an
error, really it is a programmer error at build time because a segwit
key should never be compressed, however, for historical reasons we do
not enforce this in the type system. As a step towards clarity make it
an error to call `wpubkey_hash` on a an uncompressed pubkey. This adds
documentation and potentially might assist debugging for newer devs.
Currently the feature enabling is different for "std" and "no-std",
which is again different to the order in the dependencies section. These
two things make reading the manifest harder than it needs to be.
Put the dependencies in alphabetic order in the dependencies section as
well as when enabling them.
Refactor only, no logic changes.

b5ce219c62 add weight method to InputWeightPrediction (conduition)
Pull request description:
The `P2WPKH_MAX` constant assumed DER signatures in the witness have a max length of 73. In practice, their maximum length is 72, because [BIP62](https://github.com/bitcoin/bips/blob/master/bip-0062.mediawiki) forbids nodes from relaying transactions which contain non-canonical ECDSA signatures (i.e. TX sigs must have an $s$ value of less than $\frac{n}{2}$).
This means $s$ is never encoded with a leading zero byte, and the signature as a whole never exceeds 72 bytes in total encoded length. The `ground_p2wpkh` function was already correct; only the constant needed to be corrected.
Technically 73 bytes *is* the upper limit for signatures, as nothing forbids miners from including such non-standard transaction signatures in blocks, but for the purposes of fee estimation and input weight prediction, 72 is the number which 99.9% of implementations should use as their ceiling. We already use it as the ceiling for the `ground_p2wpkh` function - `ground_p2wpkh(0)` returns a prediction which uses a witness signature of length 72.

The P2WPKH_MAX constant assumed DER signatures in the witness have
a max length of 73. However, their maximum length in practice is 72,
because BIP62 forbids nodes from relaying transactions whose ECDSA
signatures are not canonical (i.e. all sigs must have an s value of
less than n/2). This means s is never encoded with a leading zero
byte, and the signature as a whole never exceeds 72 bytes in total
encoded length. The ground_p2wpkh function was already correct;
only the constant needed to be corrected.
Currently we derive `impl Debug for PrivateKey` for "std" builds and
manually implement an obfuscated version for "no-std" builds. Since
we enable the `hashes` feature of `rust-secp` this is unnecessary
because secp takes care of obfuscating the secret for us.
We do not need this dependency because we can get the serde derives
directly from `serde`.

Pull request description:
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically
used the `core2` crate to provide copies of the `std::io` module
without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.
Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
This is mostly done, I'm still finalizing the `io::Error` commit at the end to drop the `core2` required dep in no-std, but its getting there. Would love further feedback on the approach or code-level review on these first handful of commits.

2. Separate public and private use statements
Recently we discussed a way to separate the public and private import statements to make the code more clear and prevent `rustfmt` joining them all together.
Separate public exports using a code block and `#[rustfmt::skip]`. Has the nice advantage of reducing the number of `#[doc(inline)]` attributes also.
1. Modules first, as they are part of the project's structure.
2. Private imports
3. Public re-exports (using `rustfmt::skip` to prevent merge)

In order to move towards our own I/O traits in the `rust-bitcoin`
ecosystem, we have to slowly replace our use of the `std` and
`core2` traits.
Here we take the second big step, replacing
`{std,core2}::io::Read` with our own `bitcoin_io::io::Read`. We
provide a blanket impl for our trait for all `std::io::Read`, if
the `std` feature is enabled, allowing users who use their own
streams or `std` streams to call `rust-bitcoin` methods directly.
Since we are no longer relying on the blanket `io::Write` impl for
`&mut io::Write`, we should now ensure that we do not require
`Sized` for our `io::Write` bounds, as its unnecessarily
restrictive and can no longer be worked around by simply adding an
`&mut`.
`std::io::Write` is implemented for all `&mut std::io::Write`. This
makes it easy to have APIs that mix and match owned `Write`s with
mutable references to `Write`s.
However, in the next commit we add our own `Write` trait which we
intend to implement for all `std::io::Write`. Sadly, this is
mutually exclusive with a blanket implementation on our own
`&mut Write`, as that would conflict with an `std::io::Write`
blanket impl.
Thus, in order to use the `Write for all &mut Write` blanket impl
in rust-bitcoin, we'd have to bound all `Write`s by
`std::io::Write`, as we're unable to provide a blanket
`Write for &mut Write` impl.
Here we stop relying on that blanket impl in order to introduce the
new trait in the next commit.
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.
Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically

for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.
Here, we add a new `bitcoin_io` crate, making it an unconditional
dependency and using its `io` module in the in-repository crates
in place of `std::io` and `core2::io`. As it is not substantial
additional code, the `hashes` io implementations are no longer
feature-gated.
This doesn't actually accomplish anything on its own, only adding
the new crate which still depends on `core2`.

01e2233f6c Remove deprecated since NEXT-RELEASE (Tobin C. Harding)
Pull request description:
Not sure what happened here but our release job didn't catch this? We should have updated this to "since = 0.31.0" before release. Since we only deprecate for one release lets go ahead and remove this.

Currently we have functions on `Address` that call through to a public
`Payload` type. The `Payload` type is an implementation detail and
should never have been public. In preparation for modifying the
`AddressInner` and removing `Payload` altogether lets move all the
functionality from `Payload` into `Address` - this is basically just
code moves so it is feasible to review with some confidence.
This is an API breaking change because it makes `Payload` private and
also removes from the pubic `Address` API functions that accept and
return `Payload`. Apart from that the changes can be seen as
refactoring.
The `AddressEncoding` type exists solely to assist us in implementing
`Display` on `Address`, it may have been used in the past by alt-coins
back when we had a more tolerant outlook on supporting them. Nowadays
we explicitly do not support alts.
Not sure what happened here but our release job didn't catch this? We
should have updated this to "since = 0.31.0" before release. Since we
only deprecate for one release lets go ahead and remove this.
The difficulty is a ratio of the max and current targets, since the
max is network specific the difficulty calculation is also network
specific.
We already have network specific maximum target constants, use them when
calculating the difficulty.
e21ee381bc Split Prevouts errors out into specific error types (Tobin C. Harding)
Pull request description:
Done as part of the great error clean up.
Currently we are returning a general `Error` from `Prevouts` functions, this is un-informative, we can do better by returning specific types that indicate the exact error path.

fde6479c6a Create uniform build script (yancy)
Pull request description:
Previously, each unique compiler cfg attribute that appeared in the codebase was hard coded and emitted to stdout at compile time. This meant keeping the file up to date as different compiler cfg attributes changed. It's inconsequential to emit a compiler version that's not used, so this change just emits all possibilities to reduce the maintenance burden of the build script.
Note that there is a bit of diff noise in one of the `build.rs` since I simply did a copy of one to the other to make them uniform.

Improve the public exports in two ways:
1. Inline re-exports into the docs of the module that re-exports them.
2. Separate public and private use statements
Recently we discussed a way to separate the public and private import
statements to make the code more clear and prevent `rustfmt` joining
them all together.
Separate public exports using a code block and `#[rustfmt::skip]`. Has
the nice advantage of reducing the number of `#[doc(inline)]` attributes
also.
1. Modules first, as they are part of the project's structure.
2. Private imports
3. Public re-exports (using `rustfmt::skip` to prevent merge)
Use the format
```rust
mod xyz;
mod abc;
use ...;
pub use {
...,
};
```
This patch introduces changes to the rendered HTML docs.
Done as part of the great error clean up.
Currently we are returning a general `Error` from `Prevouts` functions,
this is un-informative, we can do better by returning specific types
that indicate the exact error path.
Add two signing examples to showcase signing a simple one input two
output transaction using both segwit v0 outputs and taproot outputs.
This patch is the result of the recent rust-bitcoin TABConf workshop,
wit bug fix by Sanket, updated to use APIs from tip of master branch.
This code, depending on v0.30.0 is what is being introduced to the
cookbook at the moment.
Previously, each unique compiler cfg attribute that appeared in the
codebase was hard coded and emitted to stdout at compile time. This
meant keeping the file up to date as different compiler cfg attributes
changed. It's inconsequential to emit a compiler version that's not

875545517d Add clippy exceptions for needless_question_mark lint (Steven Roose)
Pull request description:
This lint forces you to write semantically different code that is in most cases inferior, just to save you 5 characters.
The reason why the code is inferior is because it doesn't do error conversion so it would break when either of the two function signatures changes while in the original code using the `?` operator, nothing would break if the inner error can be converted into the outer error.
