v0.8.0

Added

• 100% test coverage for all Rust code (67 tests total)
• Comprehensive unit tests for all traits: Num, SignNum, ToSigned, MaxValue, LinkType
• Edge case tests for unsigned to signed conversion (wrapping behavior)
• Integration tests for combined trait usage
• CI/CD pipeline with GitHub Actions for automated testing, linting, and releases
• Code coverage reporting with cargo-llvm-cov
• Changelog fragment system for automated version management
• Contributing guidelines with development workflow documentation
• Pre-commit hooks configuration for code quality checks

Changed

• Migrated from nightly Rust (nightly-2022-08-22) to stable Rust toolchain
• Updated Rust edition from 2018 to 2021
• Updated num-traits dependency from 0.2.14 to 0.2.19
• Set minimum Rust version (MSRV) to 1.70

Removed

• BREAKING: Removed Step trait bound from LinkType trait
  • The std::iter::Step trait remains unstable in Rust (tracking issue #42168)
  • Types implementing LinkType no longer need to implement Step
  • This is required for stable Rust compatibility
• Removed #![feature(step_trait)] and #![feature(trait_alias)] feature flags

Fixed

• Corrected license declaration in rust/Cargo.toml from LGPL-3.0 to Unlicense (public domain)
• Updated license description in CONTRIBUTING.md from LGPL-3.0 to Unlicense (public domain)

Changed

• Added Unlicense badge to all README files (root, Rust, C#, C++)
• Added License section to all README files explaining the Unlicense and its advantages over LGPL

Fixed

• Added missing cargo publish step to CI/CD pipeline, fixing issue where releases
  were created on GitHub but never published to crates.io (#127)
• Fixed deprecated ::set-output command in version-and-commit.mjs
• Added RUSTFLAGS: -Dwarnings to CI/CD pipeline for stricter compilation checks

Changed

• Migrated all CI/CD pipeline scripts from Node.js (.mjs) to Rust (.rs) using rust-script
• Updated workflow to use rust-script for all script execution, eliminating Node.js dependency

Added

• Smart change detection job (detect-code-changes.rs) to skip unnecessary CI jobs
• Version modification check to prevent manual version edits in PRs
• Crates.io-based release check instead of git tag check (check-release-needed.rs)
• Graceful crates.io publish script with auth error handling (publish-crate.rs)
• Clippy lint check in CI pipeline
• Doc tests (cargo test --doc) in CI pipeline
• Package verification (cargo package --list) in CI build
• PR-diff-aware changelog fragment validation (check-changelog-fragment.rs)
• Changelog PR release mode for manual release workflow
• Multi-language repository path detection utility (rust-paths.rs)
• Case study documentation for issue #132

Fixed

• CI/CD "Auto Release" failure caused by hard-failing on missing CARGO_REGISTRY_TOKEN
• Job dependency conditions now use always() && !cancelled() pattern for correct behavior

Added

• Rust-specific README.md with detailed description,
  usage examples, and crate badges
• C# language-specific README.md with namespace docs,
  installation, and usage examples
• C++ language-specific README.md with Conan
  installation and usage info

Changed

• Root README.md now uses a badge table for all
  language versions (C#, C++, Rust)
• Replaced Gitpod badge with GitHub Codespaces badge
• Updated Cargo.toml readme field to point to
  Rust-specific README.md

Fixed

• Rust crate on crates.io was displaying generic root
  README instead of Rust-specific documentation

Fixed

• Removed unused std::process::exit import from scripts/get-bump-type.rs that caused a compiler warning

Fixed

• Fixed panic in scripts/create-github-release.rs caused by unsupported regex lookahead assertion (?=...) in Rust's regex crate, which prevented GitHub release creation for v0.3.0

Changed

• Rename Rust traits to use full English words: Num → Number, SignNum → SignedNumber, LinkType → LinkReference
• Add documentation comments to all public traits with examples

Changed

• Upgrade Rust edition from 2021 to 2024 (stable since Rust 1.85)
• Bump MSRV from 1.70 to 1.85 (required for edition 2024)
• Move tests from src/imp.rs to tests/traits.rs as proper integration tests

Fixed

• Fix CONTRIBUTING.md incorrectly stating "nightly toolchain" (project uses stable)
• Fix README.md showing outdated install version 0.4 instead of 0.5
• Regenerate Cargo.lock to match current version (0.5.0)

Added

• Implement for_each_integer_type! macro (resolves TODO)
• Document IDE alias design decision for LinkReference trait (resolves TODO)
• Add 8 new integration tests (total: 75 integration + 6 doc tests)
• Add crate-level documentation in lib.rs
• Add automated rustdoc deployment to GitHub Pages after release
• Add case study documentation for issue #142 audit findings

Added

• TryFrom<T> and TryInto<T> bounds (with Error: Debug) for all 12 integer types on LinkReference
• from_byte(n: u8) -> Self default method on LinkReference for creating small constants from u8 values
• Sized bound on LinkReference
• Explicit u128 support as a LinkReference type (enables referencing very large link address spaces)

Added

• WrappingArithmetic composite trait bundling WrappingAdd, WrappingSub, WrappingMul, WrappingNeg, WrappingShl, WrappingShr from num-traits
• WrappingArithmetic as a supertrait of LinkReference, enabling downstream crates to use wrapping arithmetic with T: LinkReference without additional + WrappingAdd bounds
