v5.1.x Patch Notes

About Patch Versions

Patch versions (5.1.1, 5.1.2, etc.) contain bug fixes, documentation improvements, and minor internal refactorings that don’t change the public API surface. This document tracks all patch-level changes within the v5.1 minor version.

Future Patches

This section will document any future patch-level changes for v5.1.x releases.

Breaking Change

If you were using the PlaceableInstance component in v5.0.0, you’ll need to migrate to the new metadata-based approach. See the Placement Persistence guide for details.

Why this is minor: The change doesn’t affect the public API surface - it’s an internal implementation improvement that makes persistence more reliable and easier to use.

Changes:

• Removed PlaceableInstance node-based tracking
• Added gb_placement metadata dictionary for tracking placed objects
• Introduced GBPlacementPersistence utility class for save/load operations
• Updated all placement workflows to use metadata instead of components

Migration Steps:

1. Replace PlaceableInstance references with metadata queries using get_meta("gb_placement")
2. Update save/load logic to use GBPlacementPersistence.get_all_placed_objects() and save_placement_data()
3. See the Placement Persistence Migration guide for detailed examples
