v1.32.1

Fixed various deprecation warnings for newer Unity versions.

v1.32

Replaced the multi-threaded system with a worker system for better performance and more configuration options.
Settings window now includes options for the limiting number of CPU cores used by Map Graph.
Improved thread-safety of the main thread calls system, fixing possible deadlock issues.
Made improvements to reduce memory usage.

v1.31

Added right-click menu option for grouping selected nodes, as a shorthand for quickly creating a new group and adding the nodes to it.
Added Ctrl+U keyboard shortcut for detaching selected elements from a group.
Added Detach Nodes & Delete Group option to the right-click menu as an easy way to delete a group without deleting its contents.
Added "Enable Previews" toggle option under "Tools > Map Graph > Open Editor Settings". (Disabling previews reduces execution time in the editor)
When copying a node, the enabled status for each input port's constant field is now also copied over.
When copying a node, the visibility of each input port's constant field is now updated correctly.
Runner inspector now sets RequiresConstantRepaint to true, so that the execution time is updated more constantly, without needing user interactions such as mouse movement.
Moved "Restore Defaults" button to the bottom of the Map Graph Editor Settings window to avoid accidental clicks.
Fixed issue where running graphs asynchronously would sporadically not finish correctly.

v1.30.2

Fixed node comments text color for newer versions of Unity.

v1.30.1

Added fields to ports for setting a constant value without needing to connect to another node.
Processor nodes can now be disabled.
The name of required ports are now underlined.
Fixed issue where node wouldn't be in the correct subcategory.
Fixed issue where Data To Texture node would return a gray texture when main thread time per frame limit is enabled.

v1.30

Added fields to ports for setting a constant value without needing to connect to another node.
Processor nodes can now be disabled.
The name of required ports are now underlined.
Fixed issue where node wouldn't be in the correct subcategory.
Fixed issue where Data To Texture node would return a gray texture when main thread time per frame limit is enabled.

v1.29

Added "Line Paths" node.
Added "A-star Paths" node.
Added "Random Walker Paths" node.
Added "Draw Paths" node.
Added "Merge Paths" node.
Added "Extract Areas & Draw Connections (A-star)" sub graph.
Added "Extract Areas & Draw Connections (Lines)" sub graph.
Added option to set an icon for a custom node view.
Added "Simple Merge?" port to the Merge Areas node. Enabling this will not merge any connected nodes together. Instead, it simply merges the two provided area arrays together as they are.
Added "Single Point Areas?" port to the Points To Areas node. Enabling this will not merge any connected points together in the same area. Instead, it simply creates an area for each of the provided points.
Renamed "Cellular Automata Texture" to "Cellular Automata Texture (Legacy)" sub graph.
Added a new "Cellular Automata Texture" sub graph, that uses the new Cellular Automata Smoothing instead of the legacy version.
Improved graph validation system, which fixes an issue that could leave a graph in an invalid state.
Made Data To Texture node compatible with asynchronous mode.
Fixed issue with multi-threading, where in certain cases, graph processing would not finish correctly due to missing required objects after scene loading.
Fixed issue with certain node views, that wouldn't create a valid preview image if no data was provided to them.
ScriptGraphProcessor now uses a NewScriptGraphInstanceProvider by default if none is set explicitly.
Fixed obsolescence warning for newer Unity versions.
Changed wording on the "Output Parameters" section of the Map Graph Runner's inspector, to avoid confusion.
Manual: Added a section about running ScriptGraphProcessor directly to the "Running graphs from scripts" page.

v1.28

Added ability to register ScriptableObjects as dependencies to a graph asset.
Added static Get method to the ScriptGraphProcessor class to get dependencies outside the context of a node.
Added option to reload the graph editor window to the ellipsis menu (or using F5).
Script graph editor window now gets closed whenever loading its graph throws an exception, instead of leaving open a blank window, that's stuck in an invalid state.

v1.27.1

Fixed issue where running graph from script using RunSync, would run the graph asynchronous instead.
Made Tilemap To Texture node compatible with asynchronous mode.
Manual: Changes to order of sections and fixed typo (many likely still remain)

v1.27

Added ability to register dependencies to use in custom nodes.
Added ports to the "Texture To GameObjects" nodes to offset generated game objects on the Z-axis (or Y-axis when using XZ plane).
Added "Random Noise" node.
Added "Map Graph/Custom Node Script" entry to the asset create menu, to make the creation of custom nodes more convenient.
Added new methods to the Rng class for getting random bools, floats and doubles within a specific range.
Preview images now also show the latest result in graph editor windows that aren't visible at the time of execution.
Undo/redo actions now only triggers reloads of graph editor windows that are visible. Other graph editor windows now get reloaded when they become visible instead. This should improve undo/redo performance when working with multiple graph editor windows open at a time.
It's also used when using the "Use XZ Plane" is set to true on the "Texture To GameObjects" nodes, spacing the objects based on the prefab depth value instead of the prefab height value.Added "Prefab Depth" field to prefab sets. This is used for the new depth offset options when generating game objects.
Added Use XZ Plane to Texture To GameObjects node.
Fixed issue where a node wouldn't get framed and highlighted if it throws an exception.
Fixed issue where undo/redo actions could cumulatively slow down subgraph execution in the editor.
Fixed various issues that could occur when renaming a port or changing its type.
Removed "No colors connected" warning from the perlin noise node.
Added more descriptive error message in case a named color set is not assigned.
Added more descriptive error message in case a color doesn't exist in a named color set.
Sample Project: Added the "3D Terrain (Height Offset)" example.
Sample Project: Added the "3D Prefabs (Random Height Offset)" example.
Manual: Added filter for the table of contents and a search bar, the latter only works in the online version.
Manual: Offline version of the manual now includes CSS and JS assets, to improve its usability without an internet connection.
Manual: Added tutorial page about registering your own dependencies to use in custom nodes.
Manual: Added information about the Sample Project's dependencies on the Built-In Render Pipeline.
Manual: Renamed some of the tutorials in the ToC to be a bit more concise.

v1.26.2

Fixed issue where Map Graph Input component editors wouldn't draw correctly and throw errors.
When upgrading from v1.26 or earlier, deduplication of IDs now also migrates the input parameter values on graph runners and Map Graph Input components.

v1.26.1

Fixed issue where duplicating a graph file would lead to nodes having non-unique IDs in the duplicate.
Renamed "Waveform Function Collapse" to "Wave Function Collapse".

v1.26

Added a search bar to the graph editor. You can now use Ctrl+F, or the new "Search In Graph" option in the ellipsis menu, to open a search bar at the bottom of the editor, where you can search for:

Nodes, reference nodes and groups by name.
Node comments.
Notes by title and content.

Improved the cellular automata smoothing node:

It no longer has a bias towards creating bottom-left to top-right looking "shapes", providing better randomness.
Added a new "Neighbor Threshold" in port to control the amount of neighbors needed to change a cell to the fill color, which defaults to 4.
As the new results can vary greatly from the old behavior, the old behavior is still available as the "Cellular Automata Smoothing (Legacy)" node, to avoid breaking existing graphs.

Moved the "Open" button on the process graph nodes to the right-click context menu as the "Edit Graph" option.
Added an "Inspect Graph" option on the process graph nodes to the right-click context menu, which selects the graph's file in the project window, displaying it in the inspector.
Added an "Inspect Graph" option to the ellipsis menu on the graph editor window, which selects the graph's file in the project window, displaying it in the inspector.
Added graph icon to the process graph nodes, to easily distinguish them from other nodes.
Fixed issue where creating a new type in a set linked to a named color set, with a name that was already present in that named color set, would cause a "named already exists" warning, instead of linking it to the existing color. This would leave the named color set in an invalid state.
Fixed issue where selected nodes would get deselected whenever a node (or nodes) were framed inside the graph editor.
Added a check to named color set methods, to check if the set hasn't been deleted before being called by a linked set, as this was causing null reference exceptions.

v1.25.2

Improved compatibility with entering play mode without domain reloads.

v1.25.1

Fixed issue where newly added nodes wouldn't show up until after reloading the graph editor window.
Renamed Random Points Per Area Node to Random Points Per Area.
Removed log message that would appear whenever a graph editor window's position was stored.
Manual: Added Merge Point Pairs node to the node index.
Manual: Added Random Points Per Area node to the node index.
