+All notable changes to this project will be documented in this file.
+
+
+## [v3.3] - 2017-12-04
+
+### Added
+- Add runtime option to run just the Triad kernel.
+- Add runtime option for CSV output of results.
+- ROCm HC implementation added for AMD GPUs.
+
+### Changed
+- Renamed project to BabelStream (from GPU-STREAM).
+- Update SYCL Makefile to use ComputeCpp path variables.
+- SYCL exceptions are now fatal, and are propagated to a runtime exception.
+
+
+## [v3.2] - 2017-04-06
+
+### Added
+- Build instructions for RAJA and Kokkos libraries.
+
+### Changed
+- Use RAJA and Kokkos internal iterator types instead of int.
+- Ensure RAJA pointers do not alias.
+- Align memory to 2MB pages in RAJA and OpenMP.
+- Updated Intel compiler flags for OpenMP, Kokkos and RAJA to ensure streaming stores.
+- CUDA Makefile now uses variables to set compiler and flags.
+- Use static shared memory for dot kernel in CUDA and HIP.
+
+### Fixed
+- Fix initialisation of b array bug in Kokkos implementation.
+
+
+## [v3.1] - 2017-02-25
+
+### Added
+- Dot kernel HIP implementation.
+
+### Changed
+- Build system overhauled from CMake to a series of Makefiles.
+
+### Deprecated
+- Android build instructions.
+
+
+## [v3.0] - 2017-01-30
+
+### Added
+- New Dot kernel added to the 4 standard kernels.
+
+### Changed
+- All model implementations now initialise and allocate their own arrays rather than copying from a master copy. This allows for better performance on NUMA architectures.
+- Version string definition moved from header to main file.
+- Combined OpenMP 3 and 4.5 implementations.
+- OpenMP 4.5 target implementation uses alloc instead of to.
+- Made SYCL indexing consistent.
+- Update SYCL CMake build to use ComputeCpp CE 0.1.1.
+
+### Fixed
+- OpenMP deconstructor now only frees GPU memory only on GPU build.
+- SYCL template specializations for float and double.
+
+
+## [v2.1] - 2016-10-21
+
+### Added
+- New HIP version added.
+- Results for v2.0 added.
+- Output of OpenCL kernel build log on failure.
+
+### Changed
+- Use globally defined scalar value.
+- Change scalar value to stop overflow.
+- Restructure results directory.
+- Change SYCL default work-group size.
+- CMake defaults to Release build.
+
+### Fixed
+- CUDA device name output string corrected.
+- Out of tree builds.
+
+
+## [v2.0] - 2016-06-30
+
+### Added
+- Implementations in OpenMP 4.5 OpenACC, RAJA, Kokkos and SYCL.
+- Copyright headers to source files.
+- Runtime option variables are printed out.
+- Device selection added to OpenCL and CUDA.
+
+### Changed
+- Major refactor to include multiple programming models. The change now uses C++ for driver code, with different models plugged in as classes which implement the STREAM kernels.
+- Starting values in the arrays to reduce floating point errors with high iteration counts.
+- Default array size now 2^25.
+- Default to 100 iterations instead of 10.
+- CUDA thread block size set via define rather than hardcoded value.
+- Require CUDA 7 for C++11 support.
+- OpenCL C++ header updated.
+
+### Fixed
+- Various CMake build fixes.
+- Require at least 2 iterations.
+
+### Removed
+- Warning message for single precision iterations.
+
+
+## [v1.1] - 2016-05-09
+
+### Added
+- HIP implementation and results.
+- Titan X and Fury X results.
+- Output of array sizes and other information at runtime.
+- Ability to set CUDA block sizes on command line.
+- Android build instructions.
+
+### Changed
+- Update OpenCL C++ header.
+- Requires CUDA 6.5 or above.
+- OpenCL uses Kernel Functor APIs instead of make_kernel API.
+
+### Fixed
+- Unsigned integer warnings.
+
+
+## [v0.9] - 2015-08-07
+
+Initial public release of OpenCL and CUDA GPU-STREAM.
