  - (CHANGED) Curvy Generators' instances now have incremental names
  - (CHANGED) Shape Extrusion Module: the following settings are not available anymore, and are assumed to be always true: Hard Edges, Materials and Extended UV
    - The reason behind this change is to lift the legitimate confusion some users had: until now, to use one of those settings in a shape extrusion, you had to both activate the setting in the module and activate the equivalent setting in the “Meta CG Options” meta data of the relevant Control Point. Now you only need to activate the setting in the meta data
  - (OPTIM) Create Mesh module: When creating multiple meshes with mesh colliders, the colliders are baked in parallel
    - Warning: as a limitation from Unity, the parallel baking will be ignored if you set the cooking options to any value different than the default value. For more details: https://forum.unity.com/threads/physics-bakemesh-question.741257/#post-4999400

  - (FIXED) Volume Spots modules created via API can under some circumstances get their value reset
  - (FIXED) Volume Mesh module: Material settings are not undoable
  - (FIXED) In Play Mode, deleting the input splines of the Input Spline modules, if done through the module's UI, lead to incomplete deletion of said splines
  - (FIXED) Input Spline modules: Sometimes an error is logged when rasterizing a spline too densely
  - (FIXED) Input Spots module: trying to add an input after deleting all existing ones generates errors
  - (FIXED) Input Spots module: Errors when dragging a Game Object over the module
  - (Fixed) Input Game Objects: when an entry has no game object assigned, the module outputs a null game object instead of just ignoring it
  - (FIXED) Rasterize Path module: The Range and Length parameters behave as if an open spline is closed, and vice versa
    - To restore the previous behaviour if your project depends on it, set the Use Bugged Range setting to true
  - (FIXED) Shape Extrusion module sometimes extrudes a faulty mesh when it uses a different range than 0-1 and the associated Input Spline module uses a Start CP different than the first CP
  - (FIXED) Shape Extrusion module: When path range loops, and when using the Optimized setting, Advanced Scaling does not work on the path part that is beyond the looping point

  - (API/CHANGED) The BuildRasterizedPath.From setter now handles the edge value of 1 similarly to BuildShapeExtrusion.From
  - (API/FIXED) The following methods ignore the modules that implement the IOnRequestProcessing interface: CurvyGenerator.GetModuleOutputSlot(int, string) and CurvyGenerator.GetModuleOutputSlot(string, string)
  - (API/FIXED) Conform Path and Path Relative Translation modules: the output path's Length and F are not updated
  - (API/FIXED) The CGSpots(CGSpots source) constructor does not copy the source spots, but copies just the reference

- Prefabs
  - (CHANGED) Prefabs: Better handling of forbidden prefab related operations
    - Some operations, like deleting a game object, are not allowed in a prefab instance due to Unity's New Prefab System. When Curvy Generator was asked to delete an object part of a prefab instance, it showed an error message in the console. Now, it will behave as follows:
      - - If the object to delete is automatically generated, like an output mesh, and thus can be regenerated by refreshing the Curvy Generator, any operation that leads to its automatic deletion will also delete it from the prefab asset
      - - For the other cases, like deleting a module from a graph window, a popup will ask the user to first delete the associated object from the prefab asset
  - (FIXED) Create GameObject module: Errors when using input GameObjects that are prefab assets
  - (FIXED) Create GameObject and Create Mesh modules: Objects are sometimes duplicated when exiting play mode if the module is part of a prefab
- Graph View
  - (NEW) Support for the following hotkeys for modules manipulation:
    - Ctrl+D duplicate selected module
    - Ctrl+A select all modules
    - Ctrl+C copy selected module
    - Ctrl+X cut selected module (module is deleted when pasting the cut module)
    - Ctrl+V past module
  - (NEW) Support for drag and drop of Game Objects, shapes and meshes in the generator view
  - (CHANGED) Dropping a link on a module no more selects and focuses the view on said module
  - (CHANGED) Module focus is now on the top of the module instead of its bottom. This makes working with big modules, such as Volume Spots, easier
  - (CHANGED) A right click on a module now also selects it
  - (CHANGED) Dragging a module now selects it
  - (FIXED) CG's graph sometimes scrolls in weird directions when dragging a module
  - (FIXED) Couldn't deselect a selected module under some circumstances
  - (FIXED) Couldn't do a rectangle drag under some circumstances
  - (FIXED) When clicking on a module's title to drag the module, sometimes a link is dragged instead
  - (FIXED) CG's graph keeps scrolling by itself
  - (FIXED) CG's graph's preview link keeps being displayed even after the user stopped dragging it
  - (FIXED) When a selected module is deleted from outside the generator, the latter keeps highlighting the module's contour as if still existing
  - (FIXED) Clicking on an empty space does not deselect the selected link
  - (FIXED) When a link is under a module, selecting the module can select the link, and sometimes delinking it
  - (FIXED) Scrolling bars glitch when trying to drag the view beyond the graph's borders
  - (FIXED) Selecting modules via selection rectangle does not select the module's Game Object
  - (FIXED) Finishing canvas dragging while the mouse is on a module selects the module
  - (FIXED) When deselecting a module by clicking on an empty spot on the graph, the deselection takes a delay to be applied if the mouse is not moving
  - (FIXED) Canvas drag stops when hitting any keyboard key
  - (API/FIXED) CanvasState.MouseOverLink is giving wrong results
- UV and UV2
  - General
    - (NEW) Create Mesh module: When combining multiple Volume Meshes, you now have the option to recompute UV2 for the combined mesh. This can give better results than computing UV2 for each Volume Mesh individually. That option is called Unwrap UV2
    - (NEW) Volume Mesh module: Added a new setting, Unscale U, that allows for the U coordinates to be independent from the scaling
    - (CHANGED) Create Mesh module: Replaced “Add UV2” with Volume Mesh module's “Generate UV2”. Now both UV and UV2 are generated by the Volume Mesh module
    - (CHANGED) Volume Mesh module: the Keep Aspect setting now has three possible values: Off, Scale U or Scale V
    - (FIXED) Volume Mesh module: UV2 calculation is wrong when using the Split setting
      - For backward compatibility reasons, the pre Curvy 8 behaviour is still available through the Split UV2 setting, in the Backward Compatibility section
    - (FIXED) Volume Mesh module: UV2 incorrectly computed when UV is swapped or negatively scaled
    - (FIXED) Volume Mesh module: Tangents are invalid when UVs are missing, swapped or scaled negatively
    - (FIXED) Spline To Mesh window: Wrong UV2 values
    - (FIXED) Build Volume Caps module: Wrong UV2 values
    - (FIXED) Volume Caps module: The Keep Aspect enum does not work properly
  - Meta CG Options
    - (CHANGED) Now shows only the settings that are relevant (that will be used in that specific context)
    - (CHANGED) “Explicit U” and “Set U from neighbours” are now possible for CPs with a change of Material ID
    - (FIXED) When there is a change of Material ID at a specific CP, its “UV Edge” is overridden to true
      - For those relaying on that old behaviour, you will have to set “UV Edge” to true for all the CPs with a change of Material ID. You can find a code snippet that does that here: https://forum.curvyeditor.com/thread-1294.html
    - (FIXED) On the first CP of an open spline, in some cases First U is ignored when setting Explicit U (second U is used instead)
    - (FIXED) On the first CP of an open spline, First U and second U can be displayed even if the CP is not a UV Edge or has Explicit U
    - (FIXED) Exception is sometimes thrown when last CP of a spline has an Explicit U value
    - (FIXED) ArgumentOutOfRangeException when computing UV under some circumstances
    - (FIXED) When setting two points CPs to the same explicit U, the second CP will have an invalid U value under some circumstances
    - (FIXED) When setting an explicit U value to any CP other than the last one of an open spline, the automatically generated U value of the last CP is wrong
    - (FIXED) Invalid UV coordinates in some cases when using two different materials on closed splines
    - (FIXED) Shape Extrusion module: UV coordinates of an extruded shape are wrong if you activate Hard Edges and Extended UV options while not providing any value for those options
    - (API/CHANGED) MetaCGOptions.HasDifferentMaterial does not create anymore a MetaCGOptions instance at the previous CP if such instance does not exist
- Data disposal (API only)
  - In connection with the array pools addition explained earlier, instances of CGData and their inheriting classes need to be disposed. This allows for the arrays they use to be returned to the pools
    - (API/NEW) Added OutputSlotInfo.DisposableData: Whether the data outputted through this slot can be disposed when it is replaced by a newer outputted data
    - (API/NEW) Added an override for the GetData methods from the CGModuleInputSlot. That override has an out boolean parameter, isDataDisposable. That parameter tell the data consumer if the data should be disposed after being used or not

Preferences window
- (NEW) New setting: Save Generator Outputs
- (NEW) New setting: Show Hints
- (NEW) New setting: Enable Announcements
- (NEW) New setting: Enable Metrics

- Fixed several minor bugs

1.04

New:
- Added CurvySplineSegment.NextControlPoint and CurvySplineSegment.PreviousControlPoint
- Added CurvySplineSegment.IsFirstSegment and CurvySplineSegment.IsLastSegment
- Added CurvySpline.Swirl to swirl orientation vector by several modes
- Added option to show tangent gizmos
- Added option to show UserValues in the scene view
- Added CurvySplineSegment.SmoothEdgeTangent (results in orientation lerp between corners)
- Added API for better playMaker access: CurvySplineSegment.SegmentIndex, CurvySplineSegment.ControlPointIndex, CurvySpline.Segments
- Added Rails example scene
- Improved documentation
Changes:
- Changed Orientation calculation to Parallel Transport Framing, making it much more stable
- Tangent→ControlPoint orientation: First Up-Vector now keeps orthogonal
- Huge performance increase of Distance based methods
- Reworked Performance example
Fixes:
- Several fixes regarding caching
- Fixed Tangent calculation
- Fixed error when using GetNearestTF on an empty spline

1.02/1.03

New:
- Added SplineWalkerDistance script - can be useful when working with dynamic splines
- Added CurvySpline.ReloadControlPoints()
- Added new example scene: DynamicSpline
Changes:
- Improved SplineWalker script
- Control points now will be numbered consecutively when adding/deleting control points
Fixes:
- - CurvySpline.GetApproximation(), CurvySpline.GetApproximationT() and CurvySpline.GetApproximationUpVectors() returning wrong values
- - CurvySplineAlignWizard now uses ArrowCap instead of DrawArrow

1.01

New:
- Added UserValues array to Control Points, to be used with InterpolateUserValue()
- Added editor wizard to align objects to a spline
- SplineAlign script to just align position and rotation of objects both in editor and at runtime
Changes:
- SplineWalker now continuously sets initial position and rotation in the editor
Fixes:
- - Up-Vectors of closed splines not smoothed out when using Tangent Orientation
