Changelog

2.0.0 (2026-02-19)

Python 3.10–3.14. This release drops support for Python < 3.10.

Module-level import dependency analysis — --module-level CLI flag and
create_modulegraph() Python API.
- Visualizes which modules import which, with import cycle detection (-C/--cycles).
- This replaces the previous separate modvis.py that used to live at the project root.
- This analyzer now supports --root — explicit project root directory; inferred by default
  (walks up past __init__.py directories).
Supports all new syntax added after Python 3.6, up to and including 3.14.
- type statement (PEP 695 type aliases, including parameterized aliases)
  and inlined comprehension scopes.
- Walrus operator (expression assignment, :=) — tracked as both a use
  (RHS) and a definition.
- async with — __aenter__/__aexit__ protocol edges.
- match statement — class patterns, guard expressions, and body calls.
- Type annotations — AnnAssign, function argument/return annotations,
  and class-body annotations generate "uses" edges.
All five output formats (dot, svg, html, tgf, yed) available
from both create_callgraph() and create_modulegraph() APIs.

Modernized build system (hatchling via pyproject.toml).
Eliminated internal self.last_value state — analysis uses return values
and _bind_target() throughout.
Deduplicated create_callgraph() / main() analysis pipeline via shared
_build_graph().
resolve() (modvis) now uses keyword-only parameters.
sanitize_exprs renamed to canonize_exprs (the function canonicalizes,
it does not sanitize).
Comprehensive test suite: 94 tests (90 on 3.10, 94 on 3.12+), 73% coverage.
CI: GitHub Actions matrix (3.10–3.14), flake8 lint, Codecov integration.
Zero flake8 warnings across the codebase.
Sphinx extension verified and smoke-tested with current Sphinx.

Fix CLI crash on relative paths (contributed by Joenio Marques da Costa).
Fix CallGraphVisitor positional arguments issue (contributed by kuuurt).
Fix modvis from-import to detect submodule dependencies.
Fix modvis filename_to_module_name cwd fragility — paths are now made
relative to an inferred (or explicit) project root.

Thanks to kuuurt, Joenio Marques da Costa (analizo), and A M (BackBenchDevs)
for contributions included in this release.

Thanks also to Anthropic for Claude Opus 4.6 and Claude Code.

Last 1.x release.

The last compatible language version was Python 3.6.
