1.5.2

• Remove some uses of TR1/Boost in favour of C++11
• Make C++11 mandatory
• Move to Github

release-1.5.1

• Workaround for NVIDIA driver bug that prevents scan from autotuning on Pascal hardware
• Fix crash for systems with multiple NVIDIA GPUs

release-1.5.0

• Make tuning work on-the-fly instead of requiring up-front tuning
• Make the ABI robust against changes to OpenCL C++ bindings
• Add method overloads that take OpenCL C API handles
• Add free callback to setEventCallback functions
• Add support for arbitrary function objects to setEventCallback functions
• Allow algorithm objects to be default constructed, swapped, and moved
• Fix CLOGS_VERSION_MINOR

release-1.4.0

• Reduction has been added
• Introduced the ScanProblem and RadixsortProblem classes
• The cache is now stored in a SQLite database instead of lots of files
• The cache is now located in an XDG-compliant location on UNIX (~/.cache/clogs by default).
• The tuning caching mechanism has been significantly rewritten for use with SQLite
• All kernels generated during tuning are now cached (this can use a lot of space)

release-1.3.0

• Program binaries are now extracted during tuning and saved in the cache (see #8). This can also make tuning faster on systems that don't cache kernels.
• Out-of-place scan is now supported (partially implements #12).
• Workaround to avoid depending on OpenCL 1.2 ICD

release-1.2.3

• Fix a bug causing incorrect results when SCAN_BLOCKS is small (#26)
• Avoid building the unit test kernels except when testing (#24)
• Speed up tuning on CPU devices (#25)

release-1.2.2

• Fix a race condition in radix sort (mostly affects CPU devices)
• Work around an AMD driver bug that caused segfaults in tuning
• Avoid passing defines with both -D and #define

release-1.2.1

• Performance improvements, particularly for AMD GPUs
• Added --keep-going option to clogs-tune, as a temporary work-around for #23

release-1.2.0

• Kernel parameters are now autotuned (refer to user manual)
• Added benchmark support for scan
• Fixed sorting in benchmark tool to support 3-element value types
• Improved robustness to non-default locale
• Added --split-debug and --variant=symbols configuration options

release-1.1.0

• Add setEventCallback methods to Scan and Radixsort
• Worked around a bug in the Intel OpenCL compiler
