• DEPRECATE: TypedTree.iter_by_type(). Use iterator(..., kind)instead.
• New methods TypedTree.iterator(..., kind=ANY_KIND), TypedNode.iterator(..., kind=ANY_KIND), and TypedTree.count_descendants(leaves_only=False, kind=ANY_KIND)

• Add benchmarks (using Benchman).
• Drop support for Python 3.8

• t0.diff(t1, ...) adds nodes from t1 when possible, so the new status is used for modified nodes.
• t0.diff(t1, ...) marks both, source and target nodes, as modified if applicable.

• Implement check for node modifications in tree.diff(..., compare=True).
• DictWrapper supports comparision with ==.

• BREAKING:
  • kind parameter is now mandatory for add() and related methods. kind=None is still allowed to use the default (inherit or 'child').
  • Rename shadow_attrs argument to forward_attrs.
  • Enforce that the same object instance is not added multiple times to one parent.
  • Rename GenericNodeData to DictWrapper and remove support for attribut access.
  • Drop support for Python 3.8
  • mermaid: change mapper signatures and defaults
• tree.to_rdf() is now available for Tree (not only TypedTree).
• New method node.up() allows method chaining when adding nodes.
• Pass pyright 'typeCheckingMode = "standard"'.
• Use generic typing for improved type checking, e.g. use tree = Tree[Animals]() to create a type-aware container.

• Add Tree.build_random_tree() (experimental).
• Add GenericNodeData as wrapper for dict data.
• Fixed #7 Tree.from_dict failing to recreate an arbitrary object tree with a mapper.

• BREAKING: Drop Python 3.7 support (EoL 2023-06-27).
• Tree.save() accepts a compression argument that will enable compression. Tree.load() can detect if the input file has a compression header and will decompress transparently.
• New traversal methods LEVEL_ORDER, LEVEL_ORDER_RTL, ZIGZAG, ZIGZAG_RTL.
• New compact connector styles 'lines32c', 'round43c', ...
• Save as mermaid flow diagram.

• Support compact serialization forrmat using key_map and value_map.
• Better support for working with derived classes (overload methods instead of callbacks).
• Fix invalid UniqueConstraint error message when loading a TypedTree.
• Add optional tree.print(..., file=IO) argument.
• Rename default_connector_style to DEFAULT_CONNECTOR_STYLE

• Implement Tree(..., shadow_attrs=True).
• tree.load(PATH) / tree.save(PATH) use UTF-8 encoding.
• Add Tree.system_root as alias for Tree._root.
• Add Tree.get_toplevel_nodes() as alias for tree.children.
• Support and test with Py3.12: don't forget to update pip, pipenv, and tox.
• Deprecate Python 3.7 support (EoL 2023-06-27).

• BREAKING: renamed tree.to_dict() to tree.to_dict_list().
• BREAKING: changed tree.load() / tree.save() storage format.
• tree.load() / tree.save() accept path in addition to file objects.

• BREAKING: changed tree.load() / tree.save() signature, and storage format.
• Support load/save for TypedTree

• BREAKING: Rename node.move() -> node.move_to()
• New tree.copy_to() and node.copy_to()
• New tree.children property
• Configurable default connector style
