1.7

New features:

• Mappers now can define initial WFC rules. For TilemapLayer maps, rules can now be inferred from tilesets terrain settings (as suggested in #24), see example. But it currently works with square tilemaps only yet. Adding support for other shapes and layouts shouldn't be difficult.
• Added a "remap" precondition for 2D WFC, which covers the use-case discussed in #26. See the example.

1.6.1

Fix WFC2DLayeredMap mapper creation, add show/hide methods (#27).

1.6

New Godot 4.3 features supported/used:

• new TileMapLayer nodes are now supported. This includes multi-layer maps, consisting of multiple TileMapLayers - but they should be grouped under a special WFC2DLayeredTileMap node.
• non-user-editable exported properties are hidden using @export_storage (those properties are exported to make rules and related objects serializable, mostly for future rule editor support)

Exampes/demos:

• added TileMapLayer (and WFC2DLayeredTileMap) usage examples
• fixed multitile mapper example location

1.5

New features:

• Added "edge conditions" to WFC rules. See this example.
• Added multi-tile mapper. This mapper treats each N*M (configurable) rectangle of underlying map as a single tile.
• Added "sparse history" settings for solver. When both backtracking and sparse history are enabled, the solver will not store all the previous states, but just some of them - X first states and every Y'th state after them. This reduces memory usage at cost of additional solution steps performed when backtracking happens.
• Added experimental AC4-like constraint propagation algorithm. Currently, it works better in some cases but beheaves much worse than old AC3 implementation in others, so it is marked experimental and disabled by default.

Fixes:

• Solver state history is no longer stored when solution is completed. This reduces memory usage approximately twice during multithreaded WFC solver run and frees a lot of memory after solution is completed.

Examples:

• Layered TileMap example now also shows scene tiles usage.

1.4

New features:

• Added mesh metadata in 2d gridmap mapper
• Dungeon generator precondition now can use a map instead of metadata attributes as tile class configuration.

Examples:

• Added examples of 2D WFC with dungeon generator precondition
• Added camera controls in gridmap examples

Fixes:

• Fixed unsafe memory access in multithreaded runner

1.3

New features:

• Tile probabilities support added (closes #5)

Documentation and examples:

• Doc-comments added to most of documentable entities
• Added WFC generation example for hexagonal tile-map

Fixes:

• Fixed few bugs causing fatal errors

1.2

• Added preconditions for 2D WFC generator

1.1

• Layered tilemap support added (#4)
