New Libraries

• Fiber: Framework for userland-threads/fibers, from Oliver Kowalke.
• QVM: Boost QVM is a generic library for working with quaternions, vectors and matrices of static size with the emphasis on 2, 3 and 4-dimensional operations needed in graphics, video games and simulation applications, from Emil Dotchevski.

Updated Libraries

• Atomic:

  • Improved support for Oracle Studio and SPARC. The library now provides native atomic operations on SPARCv8+.
• Chrono:

  • #11330 boost::chrono::duration default constructor doesn't initialize rep_
  • #11618 Chrono IO V2 doc ios_state.hpp does not exist
  • #11631 boost chrono io v2 does not let you support custom clocks
• Circular Buffer:

  • Debug implementation is no longer used by default in debug mode. Debug implementation does not have the same thread safety guarantees as the normal (release) implementation or other containers. As a result of this change BOOST_CB_DISABLE_DEBUG macro is no longer used. BOOST_CB_ENABLE_DEBUG=1 should be defined instead to enable debug support. (#6277)
• Container:

  • Fixed bugs:

    • Trac #9481: "Minor comment typo in Boost.Container".
    • Trac #9689: "Add piecewise_construct to boost::container".
    • Trac #11170: "Doc slip for index_of".
    • Trac #11802: "Incorrect ordering after using insert() with ordered_range_t on a flat_multiset with a non-default sort order".
    • Trac #12117: "flat_set constructor with ordered_unique_range".
    • Trac #12177: "vector::priv_merge uses unqualified uintptr_t".
    • Trac #12183: "GCC 6.1 thinks boost::container::string violates strict aliasing".
    • Trac #12256: "set<std::pair<int,int>>::insert cause compilation error in debug configuration in Visual Studio 2012".
    • Trac #12273: "static_vector max_size() and capacity() should be constant expressions". Added constant static_vector<>::static_capacity to use the configured capacity in constant expressions.
    • Trac #12286: "PMR flat_map from Boost Container does not compile".
    • Trac #12296: "{deque,string} combine for a memory leak".
    • Trac #12319: "flat_set should be nothrow move constructible".
  • Revised noexcept expressions of default and move constructors in all containers.
  • Implemented C++17 insert_or_assign/try_emplace for map and flat_map.
  • Implemented C++17 extract/insert(node) for map, multimap, set, multiset.
• Context:

    • SVG: support boost::variant of geometries
    • SVG: coordinates are now written as double (by default) to svg
    • Rename namespace concept to concepts to avoid conflicts with the newest compilers
    • New spherical intersection strategy used in relational and set operations for spherical and geographic Geometries (previously cartesian intersection strategy was used for all coordinate systems).
  • Solved tickets:

    • #12189 Relational operations not compiling when point types of inputs are different
    • #12287 Invalid result of rtree.query() for contains() predicate
• Interprocess:

  • Fixed bug GitHub Pull #27 ("Fix undefined behavior").

  • New features:

    • Added new tools for inter-process logging on a local machine. The implementation includes a resource name wrapper, an inter-process message queue and a sink backend.

  • Bug fixes:

    • Fixed that logging streams could retain formatting settings across different log records. (#12178)
  • See changelog for more details.
• Math:

  • New Features:

    • Enabled all the special function code to work correctly with types whose precision can change at runtime: for example type mpfr_float from Boost.Multiprecision.
  • Patches:

    • Fix tgamma_delta_ratio for cases where the delta is small compared to the base.
    • Fix misc GCC-4.4 test failures.

  • Bug fixes

    • Trac tickets #8707, #8834, #11128, #11845, #11859, #12024,
    • Trac tickets #12093, #12103, #12224, #12241, #12257, #12378
    • Pull request PR81
• Thread:

  • #12102 condition_variable_fwd.hpp fails to compile when BOOST_THREAD_PROVIDES_INTERRUPTIONS is disabled
  • #12120 Performance improvement in thread/barrier.hpp
  • #12146 make_exceptional_future is not mentioned in the docs
  • #12202 shared_lock should be in shared_mutex header
  • #12371 boost thread/future.hpp fails to build
  • #88 fix typos in boost::upgrade_lock
  • #89 fix a bug in upgrade_to_unique_lock<>::operator=()
  • #90 fix a bug in try_lock_wrapper<>::operator=()
  • #91 Add shared_lock_guard to the included lock types
  • #92 Fixed compilation with MSVC-8.
  • #93 Fix variable shadowing warnings (Clang)

• TypeIndex:

  • ctti_type_index was made constexpr in C++14. Now it is possible to retrieve actual name of the type as const char* at compile time. So we can do a lot of interesting things at compile time: check namespace of a type, sort types according to their lexical representation, check that type is a template type and so on... A few examples were provided.
  • Fixed issue with noexcept on MSVC in type names and issue with space in type name (pulled from klemens-morgenstern/develop)

  • Variant constructors and assignment operators now do not participate in overload resolutions if variant can not hold the input type #5871, #11602
  • Fixed the issue with implicit conversion operator in C++11 #8555
  • Fixed comparisons when variant holds non-const reference #11751
  • Fixed noexcept for variant's move-assignment #11696
  • Fixed double quotes in includes #12057
  • Dropped BOOST_VARIANT_NO_REFERENCE_SUPPORT macro and dropped support for compilers without SFINAE #12250
