The develop branch will be the base for a future release.


Breaking Changes

  • Removed flipX() and flipY() sprite methods
    • They have been superseded by setFlippedX() and setFlippedY()
  • Removed setOpaqueTexture() sprite method
    • You can achieve the same result with the general setBlendingEnabled(false)
  • The Matrix4x4<T>::scale() static method has been renamed to Matrix4x4<T>::scaling()

New Features

  • Scene nodes support anchor points and non-uniform scaling
    • There is a new apptest_anchor application that shows all new node features
  • Drawable nodes support custom alpha blending factors
  • Nuklear integration for fully skinnable user interfaces
  • ImGui and Nuklear integrations support custom fonts loading
  • Added a new unclamped three channels ColorHdr class
  • The IAppEventHandler class now receives onSuspend() and onResume() events


  • The logging system is initialized earlier and can be used inside onPreInit()
  • The Android asset manager is initialized earlier and can be used inside onPreInit()
  • Handling of windows resizing events has been fixed
  • Emscripten applications react to window resizing and fullscreen events
  • Emscripten applications can now load and save local files
  • Sprite flipping methods now take a status flag
  • The version of the integrated Tracy has gone from v0.5 to v0.6.2
  • The version of the integrated ImGui has gone from v1.73 to v1.74
  • Deletion of children scene nodes upon parent destruction has been made optional
  • The Matrix4x4<T> can now translate, rotate and scale in place, avoiding a full matrix multiplication
    • It can now also be multiplied on the right side of a vector
  • Automatic sprite batching is now available on Emscripten
    • You can choose the fixed batch size with a variable in the AppConfiguration class
  • Added support for Google ANGLE libraries on Windows
  • Sorting of render commands is now stable
    • If two commands have the same material sorting key then a secondary key based on node creation time is used


  • The Emscripten port compiles with upstream LLVM WebAssembly backend
  • Some minor fixes in the color classes code
  • Culling of drawable nodes works with negative scaling factors
  • Scene nodes are now correctly transformed before children thus eliminating any update delay with nodes chains
  • Caching of TextNode boundaries does not introduce a one frame delay on update
  • The Lua stack is now cleaned after a failure in calling a function
    • Previously the stack would easily overflow if some callbacks were not defined
  • String lenght is now updated if a string is truncated when using a formatting method
  • Fixed OpenGL FBO wrapper class when dealing with reading and drawing buffers
