    • Fix is_valid which could return false for multipolygons where a polygon was located in an interior ring, all touching each other

• Hash:

  • Support for char16_t, char32_t, u16string, u32string.
• Log:

  • General changes:

    • Improved compatibility with Solaris.
  • See changelog for more details.
• Phoenix:

  • Corrected some documentation. (PR#50)
  • phoenix::erase with associative container returns iterator in C++11 mode. (#7423)
  • std::set and std::multiset should be worked with predefined lazy functions. (PR#52)
  • Disable phoenix::random_shuffle in C++17. (PR#53)
  • Don't forward declare, include instead. (#11875)
• Predef:

  • Fix Intel C/C++ version 9999 detection to be 12.1.0.
  • Addition of BOOST_PREDEF_WORKAROUND and BOOST_PREDEF_TESTED_AT macros for defect workarounds and detection.
  • Add ARM64 MSVC SIMD detection. (from Minmin Gong)
  • Add detection of iOS simulator vs device as a platform choice. (from Ruslan Baratov)
  • Fix MinGW incorrect header guard. (from Ruslan Baratov)
• Program Options:

  • Support for storing values into boost::optional, thanks to Ed Catmur (#7495, PR#18)
  • Parsing of implicit options can now use the value from the next token. Since 1.59, unless the value of implicit option was specified in the same token as the option itself, the implicit value was used. That proved inconvenient, and now we again check the next token and use it as value if it's not an option itself. (#25)
• Python:

  • eval(), exec(), and exec_statement() now allow char const * arguments, in addition to boost::python::str.
  • The boost::python::numeric API has been removed, as it is being obsoleted by boost::python::numpy.
  • Fix some build issues when using Python3 with MSVC.
• Smart Pointers:

  • New class templateatomic_shared_ptr, that provides thread-safe atomic pointer operations over shared_ptr. (Peter Dimov)
  • New class template local_shared_ptr, where the reference count is updated with non-atomic operations. (Peter Dimov)
  • More optimizations in allocate_shared and make_shared for arrays. (Glen Fernandes)
  • Documentation has been completely rewritten in Asciidoc format.
• Test:

  • Boost.test v3.6 see the Change log section for more details.
  • New feature:

    • C++17 compatibility (tested on VS2017), thanks to Daniela Engert
    • Direct comparison of C-arrays in BOOST_TEST
    • Better global fixtures mechanism, and spitting of responsibilities with BOOST_TEST_GLOBAL_FIXTURE for global fixtures and BOOST_TEST_GLOBAL_CONFIGURATION for global initialization (compile time configuration).
    • Improved support for fixtures (setup / teardown member function) which enables better teardown time checks
  • Breaking changes

    • Some API changes for the loggers
    • Deprecating BOOST_GLOBAL_FIXTURE in favor of BOOST_TEST_GLOBAL_FIXTURE and BOOST_TEST_GLOBAL_CONFIGURATION (see above)

• Typeof:

  • Fix compilation error with clang-cl ticket 11821.
• Unordered:
