v1.2.1 (2026-02-15)

• Added official support for Python 3.14. (PR #164)
  • Note: The pydantic_v1 plugin is disabled when running on Python 3.14+, as Pydantic has dropped support for its V1 legacy module.
  • Note: Python 3.14's internal representation of typing.Union and typing.Optional have changed, such that they will always render using the | operator.

v1.2.0 (2025-09-15)

• Added support for the D2 diagramming language for class diagrams. Use EntityRelationshipDiagram.to_d2() to get the D2 representation programmatically, or the CLI flag --d2 to print it to stdout. The --dot and --d2 options are mutually exclusive, and -o/--out is ignored when --d2 is used. (PR #152 and PR #162, contribution thanks to @Else00)

v1.1.1 (2025-07-19)

• Changed plugins.pydantic.get_fields_from_pydantic_model to force model rebuild. This helps address cases of unresolved forward references where Pydantic mistakenly skips rebuilding. Fixes #153. (PR #154)
• [Examples] Changed Party class in all example modules to use list instead of typing.List for the type annotation for the members field.

v1.1.0 (2025-04-12)

• Removed support for Python 3.8.
• Added Python 3.13 to supported Python versions.
• Added support for msgspec structs. (Issue #139, PR #142)
• Added --list-plugins CLI flag to print information on active plugins. (PR #144)

v1.1.0.post1 (2025-04-12)
