2.3.0 — Carta marina edition

New features

• File exclusion (-x / --exclude) — exclude files matching glob
  patterns before analysis. Patterns without a path separator match
  against the basename (e.g. test_*.py); patterns with a separator
  match against the full path (e.g. */tests/*). Available in both
  call-graph and module-level modes, via CLI, Python API (exclude
  parameter in create_callgraph / create_modulegraph), and the
  Sphinx directive (:exclude: option, comma-separated).
  (#119 — thanks @lightswitch05)

• Class-level constant attribute access — accessing class constants
  (e.g. Color.RED on an Enum, or Config.DEBUG) now creates a uses
  edge to the class itself, so these classes no longer appear
  disconnected in the graph. (#113)

• Sans-IO analysis via from_sources — CallGraphVisitor.from_sources()
  and create_callgraph(sources=...) accept (source_text, module_name)
  pairs (or (ast.Module, module_name)) for analysis without any file
  I/O. Useful for embedding pyan in tools that already have source text
  in memory, or for analyzing ASTs from macro expanders.
  (#101 — thanks @tristanlatr)

• Per-anonymous-scope isolation — multiple lambdas or comprehensions
  in the same function no longer share a single scope. Each instance
  now gets a numbered scope key (e.g. listcomp.0, listcomp.1),
  preventing the second instance's bindings from overwriting the first's.
  Works on both pre-3.12 (symtable-based) and 3.12+ (PEP 709 synthetic)
  scope paths. (#110)

• Module-graph multi-project coloring — modules are now colored by
  top-level directory relative to the project root, matching the
  call-graph analyzer's approach. Previously, modules from different
  projects could share colors if their immediate parent directories
  had the same name. (#111)

• Class-prefixed method labels when ungrouped — when grouping is off,
  method labels are now prefixed with the class name (e.g. MyClass.run
  instead of just run), making it possible to tell which class a method
  belongs to without annotations. (#112)
