Walkthrough

Adds multi-architecture build/distribute support and Buildx/binfmt orchestration, tightens packaging include lists, bumps release to 0.1.6.post2 with README note, updates .gitignore, and adjusts distribution cleanup and manylinux Dockerfile for arch/ENV handling.

Changes

Cohort / File(s)	Summary
Release metadata VERSION, README.md	Bump version 0.1.6.post1 → 0.1.6.post2; add README "Latest News" bullet noting last Python 3.8-compatible release.
Ignore rules .gitignore	Add dist*/ pattern to ignore directories whose names start with dist.
Multi-arch Docker orchestration scripts maint/scripts/docker_local_distribute.sh, maint/scripts/docker_pypi_distribute.sh	Add #!/usr/bin/env bash + set -euxo pipefail; detect host arch and map to TARGETARCH; implement docker buildx/binfmt multi-arch workflow for amd64/arm64 with per-arch builds, per-arch runs, and arch-specific dist renaming; fallback to single-arch build/run when buildx unavailable; add unsupported-arch error path.
Manylinux Dockerfile maint/scripts/pypi.manylinux.Dockerfile	Add ARG TARGETARCH; adjust arm64 builder steps (uv install path); expose CUDA-related PATH/LD_LIBRARY_PATH in final stage; set WORKDIR and virtualenv PATH/VIRTUAL_ENV handling.
Distribution cleanup script maint/scripts/pypi_distribution.sh	Extend cleanup to remove both dist and raw_dist (rm -rf dist raw_dist).
Packaging include whitelist pyproject.toml	Replace broad 3rdparty/** include with explicit allowlist mappings for TVM, CUTLASS, and Composable Kernel under tilelang/3rdparty for wheel/sdist packaging.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

• Pay special attention to:
  • maint/scripts/docker_local_distribute.sh and maint/scripts/docker_pypi_distribute.sh — buildx/binfmt flows, platform flags, artifact renaming, builder lifecycle and error handling.
  • maint/scripts/pypi.manylinux.Dockerfile — correct use of ARG TARGETARCH, arm64-install paths, and CUDA/venv env exposure.
  • pyproject.toml — ensure allowlist entries exactly match intended files.
  • .gitignore — confirm dist*/ doesn't hide needed artifacts.
  • maint/scripts/pypi_distribution.sh — verify removing raw_dist is safe.

Poem

🐰 I hopped through scripts with curious paws,

Built for many arches without a pause,
A version bumped and README bright,
Dist folders split by arch overnight,
Nose twitch — the builder works just right! 🎋

Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The pull request title "[Release] Bump version to v0.1.6.post2" is directly and clearly related to the changeset. The VERSION file summary confirms a version bump from 0.1.6.post1 to 0.1.6.post2, and the README addition announces this release as the last version compatible with Python 3.8. While the changeset also includes substantial infrastructure improvements (multi-architecture Docker support, packaging refinements, etc.), these are supporting changes for the coordinated release action. The title accurately captures the primary coordinating change—bumping the version to v0.1.6.post2—which is specific, concise, and meaningful in the context of a release PR.

🧹 Nitpick comments (1)

pyproject.toml (1)

92-102: Clarify the misleading comment on Line 92 about "same allowlist."

The wheel package mappings are valid—web search confirms all mapped paths exist in their upstream repositories: TVM has src/, python/, and version.py; CUTLASS has include/ and tools/; Composable Kernel has include/ and library/. However, the comment on Line 92 is inaccurate. The wheel scope is intentionally narrower than the sdist, not "the same"—sdist includes all 3rdparty/** (except clang/llvm exclusions), while wheel maps only these three specific subdirectories. This is the correct approach to minimize wheel size, but the comment should reflect that distinction.

Suggested fix: Update Line 92 comment to clarify intent, e.g., "Restrict 3rdparty contents in wheel to essential runtime dependencies (TVM, CUTLASS, Composable Kernel)" or similar.

Wheel builds should succeed once submodules are initialized during the actual build process.
