Fully fixed GPU memory leak when releasing SYCL, CUDA and HIP device objects
Fixed CUDA context error in some cases when using the CUDA driver API
Fixed crash on systems with an unsupported AMD Vega integrated GPU and old driver
Fixed memory leak when releasing SYCL, CUDA and HIP device objects
Fixed memory leak when initializing Metal filters
Improved denoising quality (better fine detail reconstruction)
Added Intel Meteor Lake GPU support (in Intel® Core™ Ultra Processors)
Added Metal device for Apple silicon GPUs (requires macOS Ventura or newer)
Added ARM64 (AArch64) CPU support on Windows and Linux (in addition to macOS)
Improved CPU performance
Significantly reduced overhead of committing filter changes
Switched to the CUDA driver API by default, added the OIDN_DEVICE_CUDA_API CMake option for manually selecting between the driver and runtime APIs
Fixed crash when releasing a buffer after releasing the device
Added support for denoising 1-channel (e.g. alpha) and 2-channel images
Added support for arbitrary combinations of input image data types (e.g. OIDN_FORMAT_FLOAT3 for color but OIDN_FORMAT_HALF3 for albedo)
Improved performance for most dedicated GPU architectures
Re-added OIDN_STATIC_LIB CMake option which enables building as a static (CPU support only) or a hybrid static/shared (GPU support as well) library
Added release() method to C++ API objects (DeviceRef, BufferRef, FilterRef)
Fixed possible crash when releasing GPU devices, buffers or filters
Fixed possible crash at process exit for some SYCL runtime versions
Fixed image quality inconsistency on Intel integrated GPUs, but at the cost of some performance loss
Fixed future Windows driver compatibility for Intel integrated GPUs
Fixed rare output corruption on AMD RDNA2 GPUs
Fixed device detection on Windows when the path to the library has non-ANSI characters
Added support for Intel® oneAPI DPC++/C++ Compiler 2024.0 and compatible open source compiler versions
Upgraded to oneTBB 2021.10.0 in the official binaries
Improved detection of old oneTBB versions
Fixed performance issue for Intel integrated GPUs using recent Linux drivers
Fixed crash on systems with both dedicated and integrated AMD GPUs
Fixed importing D3D12_RESOURCE, D3D11_RESOURCE, D3D11_RESOURCE_KMT, D3D11_TEXTURE and D3D11_TEXTURE_KMT external memory types on CUDA and HIP devices
Fixed the macOS deployment target of the official x86 binaries (lowered from 11.0 to 10.11)
Minor improvements to verbose output
