Updated Libraries

• Any:

  • RTTI is not required any more (TypeIndex library is used for RTTI emulation)
  • Fixed #8958
• Asio:

  • Fixed the kqueue reactor so that it works on FreeBSD (#10606).
  • Fixed an issue in the kqueue reactor which resulted in spinning when using serial ports on Mac OS (#10496).
  • Fixed kqueue reactor support for read-only file descriptors (#10367).
  • Fixed a compile error when using the /dev/poll reactor (#10350, #10572).
  • Changed the Windows backend to use WSASocketW, as WSASocketA has been deprecated (#10534).
  • Fixed some warnings reported by Visual C++ 2013 (#10376).
  • Fixed integer type used in the WinRT version of the byte-order conversion functions (#10539).
  • Changed documentation to indicate that use_future and spawn() are not made available when including the asio.hpp convenience header (#10567).
  • Explicitly marked asio::strand as deprecated. Use asio::io_service::strand instead.
• Circular Buffer:

  • Fixed some warnings and move_if_noexcept from Boost.Move is used #7888
• Config:

  • BOOST_HAS_PRAGMA_DETECT_MISMATCH macro was added
• Container:

  • Added support for initializer_list. Contributed by Robert Matusewicz.
  • Fixed double destruction bugs in vector and backward expansion capable allocators.
  • Fixed bugs:

    • Trac #10263 ("AIX 6.1 bug with sched_yield() function out of scope").
    • GitHub #16: Fix iterators of incomplete type containers. Thanks to Mikael Persson.

  • #10536 call to 'begin(...pull_coroutine< R > & c)' is ambiguous
• Flyweight:

  • Added serialization support via Boost Serialization.
  • flyweight default constructor was made explicit in Boost 1.56, which introduces a regression in some initialization scenarios. The former non-explicit default constructor has been restored (ticket #10439).
• Geometry:

  • Improvements

    • The support of parameters convertible to value_type in rtree insert(), remove() and count() functions
  • Solved tickets

    • 8402 Implicit conversion warnings

  • Bugfixes

    • Several fixes of bugs in algorithm buffer
    • Bug in point_on_surface() for CCW Polygons (extreme_points()) and numerical issue (thanks to Matt Amos)
    • Bug in disjoint() for A/A fixed by replacement of point_on_surface() with point_on_border() (thanks to Matt Amos)
    • The result of convex_hull(), duplicated Point in open output, too small number of Points for 1- and 2-Point input
    • Imprecision for big coordinates in centroid(), fixed by Points translation (related with ticket 10643)
    • for_each_segment() not taking into account the last segment of open Geometry
• Interprocess:

  • Removed unique_ptr, now forwards boost::interprocess::unique_ptr to the general purpose boost::movelib::unique_ptr class from Boost.Move. This implementation is closer to the standard std::unique_ptr implementation and it's better maintained.
  • Fixed bugs:

  • Some internal changes, library now consist of multiple headers instead of a single one #10391, #10173
• Math:

  • Added Hyperexponential Distribution.
  • Fix some spurious overflows in the incomplete gamma functions (with thanks to Rocco Romeo).

  • Fixed some corner cases in function round.
  • Don't support 80-bit floats in cstdfloat.hpp if standard library support is broken.

  • Added tuple functionality to parallel all array functionality.
  • Fixed VC++ problems with empty tuple data.
  • Updated internal is_empty to use superior variadic version when variadic macros are supported.
  • Updated clang to have same variadic support as gcc.
  • Updated doc for new functionality.
• Thread:

  • New Experimental Features:

    • #6227 Synchro: Use of variadic templates on Generic Locking Algorithms on compilers providing them

• TypeIndex:

  • BOOST_HAS_PRAGMA_DETECT_MISMATCH is now used to detect ODR violations #10404
  • Typos fixed #10294
• TypeTraits:

  • Added new traits is_copy_assignable and is_final.
• Units:

  • New unit system <boost/units/systems/information.hpp> units for: bit, byte, nat, hartley and shannon,
  • Add scale units for binary prefixes kibi, mebi, gibi, tebi, pebi, zebi and yobi IEC prefixes

  • Fix Coverity warning (GitHub #2).
• Utility:

  • The next() and prior() functions taking distance arguments were reworked. The code now work correctly when the distance is unsigned or both arguments are integers. The new code relies on the availability of operators supported by the first argument to select the correct implementation.
• uBLAS:

  • added two new types: matrix_row and matrix_column facades . With them, it is possible to access to the matrices as an array of rows and an array of columns, respectively.
  • added fixed_vector/fixed_matrix classes to represent small - fixed size containers. Requires c++11 because it is using std::array
  • fixed the long standing banded matrix bug (https://svn.boost.org/trac/boost/ticket/7549).
  • the interface of matrices and vectors has been extended with cbegin, cend, crbegin and crend member functions, as defined in c++11.
  • removed doxygen documentation to make the distribution lighter
  • removed warnings with MSVC for unused parameters
  • changed the uBlas development folder structure (will not affect users of the library)
  • performed a very large overhaul with respect to warnings and errors on various compilers. Apart for some hard to resolve warnings and older compiler incompatibilities, compilations with uBlas will be much cleaner now.
