New Libraries

• Compute: Parallel/GPU-computing library
• DLL: Library for comfortable work with DLL and DSO. Library provides a portable across platforms way to:

  • load libraries
  • import any native functions and variables
  • make alias names for C++ mangled functions and symbols
  • query libraries for sections and exported symbols
  • self loading and self querying
  • getting program and module location by exported symbol
• Hana: A modern C++ metaprogramming library. It provides high level algorithms to manipulate heterogeneous sequences, allows writing type-level computations with a natural syntax, provides tools to introspect user-defined types and much more.
• Metaparse: A library for generating compile time parsers parsing embedded DSL code as part of the C++ compilation process. The library is similar to Spirit, however while parsers built with Spirit parse at run-time, parsers built with Metaparse parse at compile-time.

• Log:

  • General changes:

    • The support for boost::basic_string_ref and its specializations is deprecated; users are encouraged to switch to boost::basic_string_view. The support for boost::basic_string_ref will be removed in future releases.
    • Added support for limiting the number of stored log files in the target directory of the file collector. Thanks to Erich Keane for the patch. (#8746)
  • Bug fixes:

    • Fixed various compilation problems for Windows CE.
    • Fixed compilation problems on Solaris.
    • Added a workaround for MSVC-10 generating broken code for formatters in some cases. (#12025)
  • See changelog for more details.
• Math:

  • Polynomial arithmetic added to tools.
• Move:

  • Experimental: asymptotically optimal bufferless merge and sort algorithms: adaptive_merge and adaptive_sort.
  • Fixed bug:

    • Trac #11758: "BOOST_MOVABLE_BUT_NOT_COPYABLE doesn't reset private access with rvalue ref version".
• Multiprecision:

  • Fixed bug in stream input for integer types, see #11857.
  • Fixed some ambiguous conversions involving expression templates see #11922.
  • Add expression template aware min/max overloads see #11149.
  • Fix bug in right shifting negative small integers in cpp_int see #11999.
  • Use memmove for bitshifts in cpp_int when possible see #9233.
  • Use memcpy for data import into cpp_int where possible, see #9235.
  • Changed cpp_bin_float.convert_to<double>() to a function template rather than proceding via long double to avoid double-rounding bug, see #12039.
  • Fixed conversions from NaN's and Infinities, see #12112.
  • Enabled better support for Clang on Windows.
  • Fixed handling of NaN's and Infinities in basic arithmetic for cpp_dec_float and cpp_bin_float, see #12090.
  • Fixed fencepost error in cpp_bin_float subtraction.
  • Fixed double-rounding in conversion to float routines for cpp_bin_float, see #12039.
  • Make float128 denorm aware, see #12075.
  • Allow the library and tests to be used without exception handling support, see #12070.
  • Fixed buggy comparison operator overloads for boost::rational.
  • Added some workarounds for Oracle C++.
  • Fixed some missing typecasts for cases where cpp_int's limb_type is wider than unsigned.
• Optional:

  • Now boost::optional is specialized for reference parameters. This addresses a couple of issues:

    • the sizeof of optional reference is that of a pointer,
    • some bugs connected to copying optional references are gone,
    • all run-time bugs caused by incorrect reference binding on some compilers are now turned into compile-time errors,
    • you can swap optional references: it is like swapping pointers: shalow, underlying objects are not affected,
    • optional references to abstract types work.
  • Documented nested typedefs (Trac #5193).
  • Made the perfect-forwarding constructor SFINAE-friendly, which fixes Trac #12002. However, this only works in the newer platforms that correctly implement C++11 <type_traits>.
  • Fixed Trac #10445.
• Regex:

  • Change to lockfree implementation of memory cache, see PR#23.
• Test:

  • Boost.test v3.2 see the 'Change log' section for details.
  • New features

    • dataset driven test-cases learned to support fixtures and variadic number of arguments
    • dataset driven test-cases sample types now honor move semantics
  • Bug fixes

    • #6767, #8905, #9443, #11854
    • #11887, #11889, #11983
• Variant:

  • Maintainance fixes.
