- namespace refactor (example: wiGraphics:: -> wi::graphics) - provided namespace compatibility macro for old user code: WICKEDENGINE_BACKWARDS_COMPATIBILITY_0_59 - resource manager will return `Resource` instead of `shared_ptr<Resource>` objects - MAD shader optimizations - implemented alpha to coverage with alpha tested materials when MSAA is enabled - alpha testing fix with transparent shadow maps - TLAS and scene buffers will be recreated less frequently when things get added/removed from the scene
