Changelog

All notable changes to LIFT are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Planned (v0.5)

  • State-vector quantum simulator (CPU, up to ~25 qubits)
  • Tensor interpreter (numpy-like execution of tensor ops)
  • Real LLVM IR lowering with cuBLAS/cuDNN runtime calls
  • Functional importers — ONNX, PyTorch FX, OpenQASM 3 (currently stubs)
  • SABRE-style dynamic qubit re-placement

Planned (v0.6)

  • True automatic differentiation (backward graph construction)
  • PyO3 Python bindings
  • Multi-file support (include / linking)
  • v1.0 release — full pipeline, benchmarks, arXiv paper

[0.4.4] — 2026-08-05

Changed

  • Automated releases via crates.io Trusted Publishing (OIDC) — no API token needed. All 13 crates configured with rustnew/Lift workflow publish.yml; pushing a v* tag publishes every crate in dependency order from CI (.github/workflows/publish.yml).
  • Version bump 0.4.3 → 0.4.4 across workspace and docs.

[0.4.3] — 2026-08-05

Changed

  • Optimised crate descriptions for discoverability: every description now leads with "LIFT compiler", so the crates surface in crates.io searches for "compiler", "compiler framework", "quantum compiler", and "AI compiler".
  • All 13 crates republished to crates.io at v0.4.3.

[0.4.2] — 2026-08-05

Fixed

  • LICENSE now ships in every published crate package (was missing from crates.io tarballs because Cargo only auto-includes LICENSE files located in each package directory, not the workspace root).
  • Repository field corrected to rustnew/Lift in all published manifests (the GitHub rename from Litf-IR had not been propagated to crates.io).
  • Docs version references bumped to 0.4.2.

Changed

  • All 13 crates republished to crates.io at v0.4.2.

[0.4.1] — 2026-08-05

Fixed

  • Corrected op/gate counts in docs (110 tensor ops, 48 quantum gates, 21 hybrid ops).
  • README examples now compile against the real API (GateDecomposition::new(Provider::IbmKyoto), DataType re-export from model_builder).
  • Repository references updated to rustnew/Lift (renamed from Litf-IR).

Changed

  • Architecture diagrams moved to Mermaid (pipeline, dependency layers, roadmap).
  • All 13 crates republished to crates.io at v0.4.1.

[0.4.0] — 2026-08-05

Added

  • Optimisation levels O0–O3 with explicit-pass override and per-pass enable/disable.
  • Semantic verification (op arity vs dialect signatures).
  • 13 optimisation passes including generic tensor fusion, hardware-native gate decomposition, real qubit routing (SWAP + BFS), non-adjacent gate cancellation & rotation merging.
  • All 13 crates published to crates.io (first full workspace release).

[0.3.0] — 2026-04-30

Added

  • Tensor / quantum / hybrid dialects.
  • Cost modelling (FLOPs, memory, energy/carbon).
  • Performance prediction (roofline analysis).
  • Export backends (LLVM IR, ONNX, OpenQASM 3.0).

[0.2.1] — 2026-04-30

Changed

  • Stability tuning.

[0.2.0] — 2026-03-31

Added

  • Initial public release of the LIFT compiler framework.
  • SSA-based intermediate representation.
  • Tensor, quantum, and hybrid dialects.
  • Core compiler infrastructure (types, values, operations, blocks, regions, verifier).
