1.29.3

Updates:

• Improve namespace collision errors to also show location of previous definition. #231, #235
• Add option for RegNode.fields() utility to also return gaps between fields. #244
• Node.children(), Node.signals(), Node.Registers(), RegNode.fields(), RegNode.aliases(), and FieldNode.aliases() now return lists rather than generators.
• Significant improvements in static type hinting. #242
  • Node iterators now advertise more accurate narrowed return types.
  • Node.parent, Node.inst, and other members are more accurately typed in subclasses
  • Expected return types annotated for all built-in properties from Node.get_property()

Bugs fixed:

• Fix internal error from compiler if parser fails to produce a parse tree. #243
• Move Node.fields() method to be exclusively for RegNode as it is meaningless for all other node types.
• Fix missed elaboration of signal's 'external' property. #245

1.28.0

Updates:

• Fix missing py.typed from installed package. #207, #241
• Fix comparison of default UDP assignment with API-provided object. #213
• Add __hash__ method for UserEnumMemberContainer. #239
• Fix use of enums in concatenation expressions. #230
• Fix an amusing edge-case that causes an out-of-memory crash. #224
