-//     - Minor adjustment to the change log
-// 
-// 0.7.3a: [ Layer Improvements ]
-//     - Added 'Layer::OnEvent()', 'Layer' now handles an event by itself and doesn't need another class to determine the event's type
-//     
-//     - Added reverse iterators 'rend()' and 'rbegin()' to 'LayerStack'
-//     
-//     - Removed 'LayerStack::On*()', 'LayerStack'
-//     
-//     - 'Layer::On*Event()' are now protected and called by 'Layer::OnEvent()'
-//     
-//     - 'Application' now handles iterating through the 'Layer's and calling the update / on * functions
-//     
-//     - Fixed a typo where in 'Mirror' where the name of the 'MirrorLayer' was "SandboxLayer" instead of "MirrorLayer"
-// 
-// 0.7.4a: [ Input ]
-//     - Added 'Input'
-//     - - Added <InputCodes>
-//     - The 'MirrorLayer''s ImGuiWindow, "GameView" will not receive/react to input events if the window is not focused
-// 
-//  0.7.4b [ Maintenance ]
-//      - Added 'Get*Ref()' to 'dxSharedContext'
-//      
-//      - Fixed 'dxFramebuffer::Resize' not resizing : /
-//      - Fixed 'dxFrameBuffer::BindAsTarget' not setting the viewport
-//      - Fixed 'dxRenderCommand::SetViewport()' not resizing the swapchain's buffer
-//      
-//      - Improved 'dxGraphicsContext''s debug interface
-//      
-//      - Removed most of the 'ComPtr's in 'dxGraphicsContext', they can be accessed with the 'm_SharedContext'
