I thought too on the point that a security-driven format change should not
strand the first LowPack archives. LowPack 0.2.1 adds a narrow, checked bridge
from format 1.0 to the stricter format 1.1 / manifest schema 2.0.

Oh! On this part, I kept reading and writing separate on purpose:

  • lowpack compatibility old.lpk authenticates and classifies an archive
    without decompressing it or writing anything.
  • lowpack migrate old.lpk -o migrated.lpk leaves the source untouched,
    preserves its compressed chunk payloads, validates the converted manifest,
    fully reconstructs every file in a temporary archive, and publishes the
    destination only after that succeeds.

The README now begins with a real release-wheel installation instead of an
editable developer install. The new getting-started and compatibility guides
cover Windows, macOS, Linux, upgrades, command discovery, checksums, and the
exact migration trust boundary.

Install the release wheel:

python -m pip install "https://github.com/devkyato/Lowpack/releases/download/v0.2.1/lowpack-0.2.1-py3-none-any.whl"
lowpack --version
lowpack doctor

What I verified before publishing:

  • 66 tests passed, with 3 expected platform-specific skips.
  • Ruff and strict Mypy passed.
  • Linux/Windows CI across Python 3.9 through 3.14 passed.
  • The package build, clean wheel install, benchmark smoke, and 5,000-run
    manifest fuzz smoke passed in GitHub Actions.
  • Two isolated builds from merged commit
    4000aec6a779eb8c3127ee91a96968b7e3b0f3d2 were byte-identical.
  • The published 0.1.2 wheel created a 23-file source archive with dictionaries;
    the 0.2.1 wheel migrated, fully verified, unpacked, and byte-matched all 23
    files.
  • The README cover is byte-for-byte the supplied LowPack cover image.

SHA-256:

This remains an alpha prerelease. It does not promise unknown future-format
compatibility, repair corrupt archives, stream canonical telemetry transforms,
or replace the need for another copy of important data.
