All notable user-facing changes to CompressKit are tracked here.

The project follows Keep a Changelog style categories and uses semantic versioning for releases.

Unreleased ​

  • RLE format now includes 4-byte magic number RLE\x00 for file type identification.

  • Added .golangci.yml for Go linting configuration.

  • Added .clippy.toml for Rust linting configuration.

  • Executable cross-language conformance matrix via make test-conformance.

  • Streaming API lifecycle and buffer contract coverage across shared C++/Go/Rust layers.

  • Unified CLI launcher module for all algorithms (shared/go/cli, shared/cpp/cli_launcher, shared/rust/cli).

  • C++ buffer API now uses platform-appropriate temp directory instead of hardcoded /tmp/.

  • Rust RLE decode now validates count=0 to prevent invalid data.

  • Rust Huffman encoding performance improved by using Vec<u8> instead of String for bitstream.

  • Fixed Rust Arithmetic Coding streaming decode compatibility for short bitstreams.

  • Fixed Rust Arithmetic Coding treatment of 0x00 input bytes so they are not confused with the EOF symbol.

  • Unified buffer growth strategies across C++, Go, and Rust for semantic consistency.

  • Transactional retry logic now preserves partial writes correctly.

  • BREAKING: RLE format now includes 4-byte magic header. Old RLE files without magic are incompatible.

  • Archived future shared-frame, extended-conformance, and benchmark-governance proposals as deferred OpenSpec design context.

  • Refined README and documentation entry points so the GitHub README stays a concise repository gateway.

  • Removed 41 unused BMAD skills from .claude/skills/ directory (~2MB reduction).

  • Simplified AGENTS.md and CLAUDE.md for better AI agent guidance.

  • Architecture Deepening: Unified CLI entry points (94% boilerplate reduction) and buffer layer orchestration.

  • Archived internal decision documents to .archive/superpowers-20260508/ for cleaner documentation structure.

1.0.0 (2026-01-07) ​

  • Huffman Coding, Arithmetic Coding, Range Coder, and Run-Length Encoding implementations.
  • C++17, Go, and Rust command-line tools for all four algorithms.
  • Unified CLI shape: <binary> <encode|decode> <input> <output>.
  • Cross-language file compatibility goals for educational verification.
  • Test data generation scripts and benchmark scripts.
  • VitePress documentation site with English and Chinese content.
  • MIT license, contribution guide, code of conduct, security policy, issue templates, and pull request template.

Security ​

  • Documented maximum input size of 4 GiB.
  • Documented maximum decoded output size of 1 GiB for decompression-bomb protection.
