Unreleased ¶

CompactTarget::block_proof, the work contributed by a block with that target, zero for negative, overflowing or zero targets.
from_hex_lossy for HashBlob, make_hash! types and Arith256, an infallible parse of the leading hex digits of a string, matching the reference implementation.
u64 operands for Arith256: +=, -=, |=, ^=, /, /=, == and !=. Inferred operands such as a == x.into() may now need a type annotation.
From<&T> conversions into Arith256 from &u8 through &u128 and &Hash256, and From<&Arith256> for Hash256.

The minimum supported Rust version is raised from 1.85 to 1.89.
HashBlob, make_hash! types and Arith256 serialize as their little-endian storage bytes for machine-readable formats. JSON retains the hex-encoded big-endian string.
The serde feature no longer implies codec. CompactTarget implements Serialize and Deserialize without codec. Callers that relied on serde to enable codec must enable it explicitly.
CompactTarget::from_str requires exactly 8 hex digits, optionally 0x/0X-prefixed. Shorter input is rejected with ParseHexError::OddLength or ParseHexError::InvalidLength.
Arith256::to_f64 rounds like the reference implementation, where it was one ULP off on roughly 1% of inputs.

ParseHexError has moved to dash-types as dash_types::ParseHexError.
The dash_types::Numeric re-export in favour of a wholesale crate re-export. dash_num::Numeric imports must switch to dash_num::__deps::dash_types::Numeric or depend on dash-types directly.
