  • 
    Solved tickets
    
    
  • 
    Bugfixes
    
• 
  Interprocess:
  
  
  • 
    Trac #10262 ("AIX 6.1 bug with variable definition hz").
    
    
  • 
    Trac #10229 ("Compiling errors in interprocess\detail\os_file_functions.hpp").
    
    
  • 
    Trac #10506 ("Infinite loop in create_or_open_file").
    
    
  • 
    GitHub Pull #11 ("Compile fix for BOOST_USE_WINDOWS_H").
    
    
  • 
    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:
    
    
  • 
    Reorganized Doxygen marks to obtain a better header reference.
    
• 
  Intrusive:
  
  
  • 
    GitHub Pull #12: Fix MSVC14 warning C4456: declaration of 'x_parent_right' hides previous local declaration
    
    
  • 
    Boost Trac #10520: Conversion warning in intrusive/detail/utilities.hpp
    
    
  • 
    Boost Trac #10469: Erasing from intrusive unordered_multiset with optimize_multikey goes into an infinite loop

  • 
    Implemented N3644: Null Forward Iterators from C++14.
    
    
  • 
    Fixed bugs:
    
• 
  Iterator:
  
  
  • 
    Most components of the library were moved into the boost::iterators namespace. For backward compatibility the components are also accessible in the boost namespace.
    
    
  • 
    Iterator operators are now conditionally defined based on the iterator category.
    
    
  • 
    Some of the internal components of the library were made public (minimum_category, for example).
    
• 
  Lexical Cast:
  
  
  • 
    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).
    
    
  • 
    Fix bug in derivative of incomplete beta when a = b = 0.5 - this also effects several non-central distributions, see issue 10480.
    
    
  • 
    Fixed some corner cases in function round.
    
    
  • 
    Don't support 80-bit floats in cstdfloat.hpp if standard library support is broken.
    
• 
  Move:
  
  
• 
  Added unique_ptr smart pointer. Thanks to Howard Hinnant for his excellent unique_ptr emulation code and testsuite.

  • 
    Trac #9785: "Compiler warning with intel icc in boost/move/core.hpp",
    
    
  • 
    Trac #10460: "Compiler error due to looser throw specifier",
    
    
  • 
    Git Pull #3: "Don't delete copy constructor when rvalue references are disabled",
    
• 
  MultiArray:
  
  
  • 
    Fixed a friend-declaration related warning for clang (thanks to Marcel Raad).
    
• 
  Multiprecision:
  
  
  • 
    Changed rational to float conversions to exactly round to nearest.

  • 
    Fixed various minor documentation issues.
    
• 
  Multi-index Containers:
  
  
  • 
    When std::tuples are available, these can be used for lookup operations in indices equipped with composite keys. boost::tuples are also supported for backwards compatibility.
    
• 
  Preprocessor:
  
  
  • 
    Added is_begin_parens and remove_parens.
    
    
  • 
    Added tuple functionality to parallel all array functionality.
    
    
  • 
    Fixed VC++ problems with empty tuple data.

  • 
    Typos fixed #10294
    
• 
  TypeTraits:
  
  
  •

  • 
    New unit system <boost/units/systems/information.hpp> units for: bit, byte, nat, hartley and shannon,
    
    
  •

  •

  • 
    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.
