- API Changes
  - Implemented separate texture samplers:
    - Added UseCombinedTextureSamplers and CombinedSamplerSuffix members to ShaderCreationAttribs structure
    - When separate samplers are used (UseCombinedTextureSamplers == false), samplers are set in the same way as other shader variables via shader or SRB objects
  - Removed BIND_SHADER_RESOURCES_RESET_BINDINGS flag, renamed BIND_SHADER_RESOURCES_KEEP_EXISTING to BIND_SHADER_RESOURCES_KEEP_EXISTING. Added BIND_SHADER_RESOURCES_UPDATE_STATIC, BIND_SHADER_RESOURCES_UPDATE_MUTABLE, BIND_SHADER_RESOURCES_UPDATE_DYNAMIC, and BIND_SHADER_RESOURCES_UPDATE_ALL flags
- Using glslang to compile HLSL to SPIRV in Vulkan backend instead of relying on HLSL->GLSL converter

v2.3.a

Core
- Added IFence interface and IDeviceContext::SignalFence() method to enable CPU-GPU synchronization
- Added BUFFER_MODE_RAW mode allowing raw buffer views in D3D11/D3D12.
- Moved Format member from BufferDesc to BufferViewDesc
- Removed IsIndirect member from DrawAttrbis as setting pIndirectDrawAttribs to a non-null buffer already indicates indirect rendering
Samples:
- Added Tutorial 10 - Data Streaming
- Added Tutorial 11 - Resource Updates

v2.3

Core:
- Implemented Vulkan backend
- Implemented hardware adapter & display mode enumeration in D3D11 and D3D12 modes
- Implemented initialization in fullscreen mode as well as toggling between fullscreen and windowed modes in run time
- Added sync interval parameter to ISwapChain::Present()
- API Changes
  - Added NumViewports member to GraphicsPipelineDesc struct
  - Removed PRIMITIVE_TOPOLOGY_TYPE type
  - Replaced PRIMITIVE_TOPOLOGY_TYPE GraphicsPipelineDesc::PrimitiveTopologyType with PRIMITIVE_TOPOLOGY GraphicsPipelineDesc::PrimitiveTopology
  - Removed DrawAttribs::Topology
  - Removed pStrides parameter from IDeviceContext::SetVertexBuffers(). Strides are now defined through vertex layout.
API Changes:
- Math library functions SetNearFarClipPlanes(), GetNearFarPlaneFromProjMatrix(), Projection(), OrthoOffCenter(), and Ortho() take bIsGL flag instead of bIsDirectX
- Vertex buffer strides are now defined by the pipeline state as part of the input layout description (LayoutElement::Stride)
- Added COMMIT_SHADER_RESOURCES_FLAG_VERIFY_STATES flag
- Added NumViewports member to GraphicsPipelineDesc structure
Samples:
- Added fullscreen mode selection dialog box
- Implemented fullscreen mode toggle on UWP with shift + enter
- Implemented fullscreen window toggle on Win32 with alt + enter
- Added Tutorial 09 - Quads
Fixed the following issues:
- Add option to redirect diligent error messages
- Add ability to run in exclusive fullscreen/vsync mode

v2.2.a

Enabled Win32 build targeting Windows 8.1 SDK
Enabled build customization through custom build config file
Implemented PSO compatibility
Fixed the following issues:

v2.2

Added MacOS and iOS support

v2.1.b

Removed legacy Visual Studio solution and project files
Added API reference
Added tutorials 1-8

v2.1.a

Refactored build system to use CMake and Gradle for Android
Added support for Linux platform

v2.1

New Features

Core

Interoperability with native API
- Accessing internal objects and handles
- Creating diligent engine buffers/textures from native resources
- Attaching to existing D3D11/D3D12 device or GL context
- Resource state and command queue synchronization for D3D12
Integraion with Unity
Geometry shader support
Tessellation support
Performance optimizations

HLSL->GLSL converter

Support for structured buffers
HLSL->GLSL conversion is now a two-stage process:
- Creating conversion stream
- Creating GLSL source from the stream
Geometry shader support
Tessellation control and tessellation evaluation shader support
Support for non-void shader functions
Allowing structs as input parameters for shader functions

v2.0 (alpha)

Alpha release of Diligent Engine 2.0. The engine has been updated to take advantages of Direct3D12:

Pipeline State Object encompasses all coarse-grain state objects like Depth-Stencil State, Blend State, Rasterizer State, shader states etc.
New shader resource binding model implemented to leverage Direct3D12
OpenGL and Direct3D11 backends
Alpha release is only available on Windows platform
Direct3D11 backend is very thoroughly optimized and has very low overhead compared to native D3D11 implementation
Direct3D12 implementation is preliminary and not yet optimized

v1.0.0

Initial release
