Sourced from django-treebeard's changelog.

Release 5.3.0 (Jun 24, 2026)

Treebeard 5.3.0 is a minor release release.

• Added support for loading data for many-to-many relationships with load_bulk(). These were previously exported when using dump_bulk(), but were not handled when loading the same data.
• Fixed an exception arising when running delete() operations on querysets that had a prefetch.
• Added a warning when the default manager for a model extending a Treebeard Node class does not subclass the corresponding Treebeard model manager. This will raise an error in the next major release of Treebeard.

Release 5.2.2 (Jun 5, 2026)

Treebeard 5.2.2 is a bugfix release.

• Fixed performance regression in MP_Node.get_ancestors() (django-treebeard/django-treebeard#403).

Release 5.2.1 (Jun 2, 2026)

Treebeard 5.2.1 is a bugfix release.

• Fixed import error for type annotation unavailable on Python 3.10.

Release 5.2.0 (Jun 2, 2026)

Treebeard 5.1.0 is a minor release that includes some bug fixes.

New features:

• Added a bulk_create option to MP_Node.load_bulk(), that creates database entries in bulk instead of one at a time.
• Added signals to MP_Node, NS_Node and LT_Node implementations to allow external data stores to stay in sync with Treebeard-based models.

Big fixes:

• Fixed MP_Node paths being incremented unnecessarily when saving nodes with node_order_by in the admin.
• Optimised MoveNodeForm to skip move logic if no treebeard-specific fields were modified.
• Changed the unique constraint for LTree.path to be deferrable, so that move operations do not fail. This requires a database migration for projects using the experimental LTree implementation.

Release 5.1.0 (May 12, 2026)

Treebeard 5.1.0 is a bugfix release.

• Fixed add_child and add_sibling behaviour for inherited models using NS_Node.
