[section:history Revision history]
[heading Boost 1.72]
* New features
* Better deduction guides for axis types and histogram type on C++17 compilers
* performance improvements in the indexing code
* new histogram::fill method for accelerated filling from chunks of values
* ASCII bar charts for 1D histograms when boost/histogram/ostream.hpp is included (contributed by Przemyslaw Bartosik)
* Passing invalid axis options causes user-friendly compile-time errors
* Wrong usage of weight() and sample() causes user-friendly compile-time errors
* algorithm::empty returns true if all histogram values are equal to the default value (contributed by Henry Schreiner)
* algorithm::reduce with shrink is now well defined when values are not bin edges
* axis::traits::rank returns the number of values that this axis accepts
* axis::traits::is_continuous returns whether an axis is continuous or discrete
* axis::traits::is_inclusive returns whether an axis has a bin for any possible input
* limited weight support for mean accumulator
* accumulators::weighted_mean::sum_of_weights_squared method added
* Fixes
* Support of -std=c++2a and -stdlib=libc++ on clang, compatibility with gcc-9
* Fixed: weight could be passed instead of a sample during filling without triggering an error
* Fixed: segfault when too many indices were passed to algorithm::project
* Fixed: indexed range generator did not work with storage based on std::array
* Fixed: weighted_mean() + weighted_mean() != weighted_mean() (discovered and reported by Henry Schreiner)
* Fixed: axis::option::test(...) returned true if any bits in the test mask were set (now returns true if all bits in the test mask are set)
* Protecting calls to min, max with against macro expansion
* Replaced all crlf with lf in concepts.qbk
* Missing throw of std::invalid_argument when user passes too many axes to histogram
* Corrected documentation of serialization support in concepts section
* Resolved warnings for various compiler versions
* Other
* Added Boost.Histogram logo
* Added missing copyright notices
* axis::category::value returns copy for scalar types and const reference otherwise
* std::ostringstream not used anymore to generate exception messages to reduces code bloat
* Documentation improvements
* Restructured overview section in documentation
* Updated user guide to demonstrate new features
* Updated accumulator examples
* Concepts explain how accumulators can optionally accept weights
* Updated benchmark code
* New test checks consistency of b2 and cmake build systems
* New test checks One-Definition-Rule (fails if non-templated function is not declared inline)
* Serialization code decoupled from Boost.Serialization
* Removed dependency on Boost.CallableTraits
