Unreleased

Support building FTorch as a static library. #448
Intel-ifx and Intel-ifort CI and GCC v9-13 CI. Intel CI builds OpenMPI from source to accomodate MPI integration tests #438
Expose tensor strides via get_stride method #416
Remove UNIX preprocessor variable that selected the right C-integer type for 64bit int. Use int64_t instead #416
A new cmake option MULTI_GPU to control the build of multi GPU integration tests in #410
Support for AMD GPU backends (HIP) provided in #385 and #388.
requires_grad property hooked up to torch_tensor in #288
MPI example added in #270
Changelog file and guidance for versioning added in #313
A new tensor manipulation demo was introduced in #291.
Backpropagation implemented with torch_tensor_backward and torch_tensor_get_gradient in #286
Zeroing of gradients associated with a tensor implemented in #341.
Exposed retain_graph argument for torch_tensor_backward in #342.
Implemented torch_tensor_zero and class method alias in #338.
Provided interface for torch_tensor_from_array with default layout in #348.
Overload taking sum and mean of tensors in #344.

Intel CI now uses Intel oneAPI MPI instead of OpenMPI built with Intel compilers #449
FTorch library (libftorch.so) produced by cmake installation now has RUNPATH that contains path to Torch library directory. Downstream targets linking against FTorch can now find the Torch dependency automatically and will compile successfully #437.
In all CMakeLists.txt where find_package(FTorch) was present, now using REQUIRE if not building tests to stop the cmake configuation process early for users who only wish to build examples in #434
fortitude dependency version increased to 0.7.0
Examples reordered to be more logical in #317
scalar multiplication/division of tensors reworked to require the scalar to first be mapped to a torch_tensor in #289
The unit tests for constructing and destroying tensors were separated out in #319
Demo numbers were bumped to account for new demo in #291.
Use interface for torch_tensor_from_array with default layout in tests and examples in #348.
Error handling in ctorch.cpp improved in #347.
