v0.3.0 (2025-11-24)

This release focuses on extracting information about package sources, but also includes quality-of-life improvements and bug fixes. There are no breaking changes.

New features:

• Arguments for pyproject.toml and lockfile paths are automatically inferred in the common cases where Ganzua is invoked from the project root. Instead of writing full paths, it is also sufficient to point to a directory containing these files. For example, ganzua inspect, ganzua inspect . and ganzua inspect uv.lock are generally equivalent.
• Keep some information about package sources (PyPI, Git, path dependencies, …) when inspecting lockfiles.
• Indicate certain kinds of differences that might need special attention in diff output (JSON/Markdown): is_major_change (M), is_downgrade (D), is_source_change (S).

Fixes:

• (https://github.com/latk/ganzua/issues/3) Normalize names of packages, extras, and dependency groups when loading pyproject.toml files, as required by the packaging specifications.
• (https://github.com/latk/ganzua/issues/4) Handle packages without versions in uv.lock files. The fake version 0+undefined will be substituted instead.

Other:

• Run tests under Python 3.14.
• Added a CHANGELOG.md file.
• Various internal changes and testing improvements.

v0.2.0 (2025-09-11)

This release fixes some bugs that were found through real-world usage, adds convenience features like diff summaries, and implements new constraint edits.

Breaking changes:

• Renamed ganzua constraints remove to ganzua constraints reset.
• Schema change for ganzua diff JSON output: diff is nested under packages key.
• Schema change for ganzua inspect JSON output: data is nested under packages key to match the diff schema.

New features:

• New command ganzua constraints inspect lists all constraints in a pyproject.toml file, including extras, environment markers, and dependency groups. This is particularly helpful for debugging Ganzua.
• New option ganzua constraints reset --to=minimum edits constraints to require at least the currently locked version, while removing any previous constraints. Essentially, this makes all direct dependencies upgradeable.
• (https://github.com/latk/ganzua/issues/2) Add a summary line to ganzua diff Markdown output that counts the number of changes.
• Add a stat section to ganzua diff JSON output that counts the number of changes.

Fixes:

• Support loading lockfiles regardless of name. Previously, lockfiles had to be named poetry.lock or uv.lock.
• (https://github.com/latk/ganzua/issues/1) Support pyproject.toml files with out-of-order tables.

Other:

• Various internal changes. Improvements to pyproject.toml manipulation. Fewer special cases for Poetry.
