[section:history Revision history]
|
|
|
|
[heading 4.0 (first boost release)]
|
|
|
|
* Removed Python bindings, will be developed in separate repository
|
|
github.com/hdembinski/histogram-python
|
|
* All axis can be made optionally circular, except category axis
|
|
* Removed circular axis (which is just a circular regular axis)
|
|
* Added indexed adaptor generator for convenient and fast iteration over histograms
|
|
* Support for axes that can grow in range
|
|
* Support for axes which accept multiple values (example: hexagonal binning)
|
|
* Support for profiles and more generally, arbitrary accumulators in each cell
|
|
* Support for serializing to xml archives
|
|
* Added compatibility with Boost.Range, Boost.Units, and Boost.Accumulators
|
|
* Added deduction guides for axis types and histogram
|
|
* Performance improvements
|
|
|
|
[heading 3.2 (not in boost)]
|
|
|
|
* Allocator support everywhere
|
|
* Internal refactoring
|
|
|
|
[heading 3.1 (not in boost)]
|
|
|
|
* Renamed `bincount` method to `size`
|
|
* Support for axes with only overflow and no underflow bin
|
|
* category axis now by default has bin for "other" input that does not fall
|
|
into the predefined categories, making it consistent with other axes
|
|
* NaN is now consistently put into overflow bin for all axes
|
|
* Eliminated warnings about safe internal conversions on MSVC
|
|
* Established a cpp house style with corresponding .clang-format file
|
|
* Better detection of Python library on all systems
|
|
* Improved code coverage by testing more input errors
|
|
* Raise ValueError instead of generic RuntimeError in Python on input errors
|
|
|
|
[heading 3.0 (not in boost)]
|
|
|
|
* Support for efficient adding of multiple histograms and scaling
|
|
* Re-design of category axis as a general mapping between unique values and bins
|
|
* Re-design of the bin description an axis returns upon element access
|
|
* Interface cleanup and simplification, more consistency between Python and C++ interface
|
|
* Iterators for histogram and axes for STL compatibility
|
|
* Regular axis in C++: Allowing transforms with state
|
|
* Regular axis in Python: Support for all C++ transforms
|
|
* Polymorphic axis::any type
|
|
* Internal refactoring from boost::mpl and boost::fusion to std::tuple and boost::mp11
|
|
* Windows support
|
|
|
|
[heading 2.0 (not in boost)]
|
|
|
|
* Added static_histogram (v1.0 only had dynamic_histogram).
|
|
* Merged wfill(...) and fill(...) interface.
|
|
* Support custom allocators in storage classes.
|
|
* Replaced static_storage with array_storage.
|
|
* Replaced dynamic_storage with unlimited_storage, which adds the capability to grow the bin counter into a cpp_int, thus avoiding integer overflow completely.
|
|
* Serialization uses binary_archive instead of text_archive. The latter is portable, but the performance is terrible.
|
|
* Python interface changed: histograms are now iterable, returning axis classes
|
|
* Support reduction (removing a subset of axes and returning the equivalent histogram; in other words, those axes are integrated over)
|
|
|
|
[heading 1.0 (not in boost)]
|
|
|
|
* First stable version.
