Changes 1.60.0:
New Libraries
VMD:
Variadic Macro Data library, from Edward Diener.

Updated Libraries
Atomic:
* Enforced proper alignment of atomic<> storage. This should fix possible \ 
issues on platforms that support atomic operations on data units larger than the \ 
native word size. This may also change binary layout of user's data structures \ 
that have atomic<> members.
* Fixed compilation for PowerPC with IBM XL C++ compiler. Corrected memory \ 
barriers in PowerPC assembler.
* Fixed compilation with MSVC-8 for ARM.
* Fixed compilation with gcc 4.4 for x86-64, when 128-bit atomic operations were \ 
used. (10994)
* Optimized some gcc assembler blocks for x86/x86-64 to reduce the number of \ 
used registers. This may require binutils 2.10 or later.

Chrono - 2.0.5:
Fixes:
* 10778 VC14 CTP4 Atomic don't compile with boost::chrono durations which are \ 
not TriviallyCopyable
* 10840 Missing std:: qualifier for puts call in test_7868.cpp
* 10851 Missing std:: qualifier for puts call in time_point_output.cpp
* 10893 Minor doc typo in Boost.Chrono
* 10992 Chrono IO state savers inconsistent with Boost.IO state savers
* 10995 duration_put::put_value truncates fractional part
* 11006 Impossible to instantiate time_fmt_io_saver due to several errors.
* 11012 chrono_io v2 fail to compile with boost::chrono::duration< \ 
boost::rational<int> >

Container:
* Implemented Polymorphic Memory Resources.
* Add more BOOST_ASSERT checks to test preconditions in some operations (like \ 
pop_back, pop_front, back, front, etc.)
* Added C++11 back/front operations to basic_string.
Fixed bugs:
* Trac 11627: "small_vector<T,n>::swap() appears to be broken".
* Trac 11628: "small_vector<int,n> iterates over elements in \ 
destructor".
* Trac 11697: "Wrong initialization order in tuple copy-constructor".
* Trac 11698: "Missing return statement in static_storage_allocator".
* GitHub 29: Doc fixes for flap_map complexity requirements.
* GitHub 31: DL_SIZE_IMPL also dereference addr.

Context:
* 11603 typo in PPC32/MACH-O asm
* support for CYGWIN

Core:
* In symbol demangling tools, added support for gabi++ ABI implementation used \ 
in Android NDK.
* Added a new enable_if_has_type tool for performing SFINAE checks for presence \ 
of a nested type.
