2.5.0:

Cube textures are now cached by texture cache (deltakosh)
Added onAnimationEnd callback for sprite.playAnimation (deltakosh)
Added support for non square textures for sprites (deltakosh)
Added support for texture arrays (deltakosh)
Added camera.isInFrustum and camera.isCompletelyInFrustum. Can be used with meshes, submeshes and boundingInfo (deltakosh)
Several memory allocation reduction (benaadams)
Several GPU state change reduction (benaadams)
MapTexture: add supersample mode to double font quality. (nockawa)
New invertUV parameter an all ribbon based shapes : ribbon, tube, lathe, basic and custom extrusion (jerome)
Text2D: new fontSuperSample setting to use high quality font (nockawa)
PerfCounter class added to monitor time/counter and expose min/max/average/lastSecondAverage/current metrics. Updated engine/scene current counter to use this class, exposing new properties as well to access the PerfCounter object (nockawa)
Better keyboard event handling which is now done at canvas level and not at window level (deltakosh)
New scene.hoverCursor property to define a custom cursor when moving mouse over meshes (deltakosh)
Canvas2D: (nockawa)
- Performance metrics added
- Text2D super sampling to enhance quality in World Space Canvas
- World Space Canvas is now rendering in an adaptive way for its resolution to fit the on screen projected one to achieve a good rendering quality
- Transparent Primitives are now drawn with Instanced Array when supported

MapTexture: Font Characters are now correctly aligned on Chrome (nockawa)
Fixed some missing parameter default values in MeshBuilder.CreateGroundFromHeightMap() and MeshBuilder.CreateTiledGround() (jerome)
Fixed cross vector calculation in _computeHeightQuads() that affected all the GroundMesh.getHeightAtCoordinates() and GroundMesh.getNormalAtCoordinates() methods (jerome)
Fixed Mesh.CreateDashedLines() missing instance parameter on update (jerome)
Added BBox update on each ribbon based shape (ribbon, tube, extrusion, etc) on dynamic updates (jerome)
Fixed model shape initial red vertex color set to zero not formerly being taken in account in the SolidParticleSystem (jerome)
Fixed RenderTargetTexture meshes selection (deltakosh)
Fixed camera speed computation (deltakosh)
Fixed bug with isntances, LOD and edgesRendering (deltakosh)
Canvas2D: (nockawa)
- WorldSpaceCanvas2D:
- Intersection/interaction now works on non squared canvas
- Primitive:
- ZOrder fixed in Primitives created inline
- Z-Order is now correctly distributed along the whole canvas object graph
- Sprite2D:
- texture size is now set by default as expected
- can have no id set
- Text2D:
- Fix bad rendering quality on Chrome
- Rendering above transparent surface is now blending correctly

Removed legacy shaders support (deltakosh)
Canvas2D: (nockawa)
- WorldSpaceCanvas2D:
- WorldSpaceRenderScale is no longer supported (deprecated because of adaptive feature added).
