Log message:
Changes 1.58.0:
* New Libraries:
  - Endian: Types and conversion functions for correct byte ordering and more \ 
regardless of processor endianness.
  - Sort: Includes spreadsort, a general-case hybrid radix sort that is faster \ 
than O(n*log(n))
* Updated Libraries:

Chamges 1.57.0:
Updated Libraries
Any:
RTTI is not required any more (TypeIndex library is used for RTTI emulation)
Fixed 8958

Asio:
Fixed the kqueue reactor so that it works on FreeBSD.
Fixed an issue in the kqueue reactor which resulted in spinning when using \ 
serial ports on Mac OS.
Fixed kqueue reactor support for read-only file descriptors.
Fixed a compile error when using the /dev/poll reactor.
Changed the Windows backend to use WSASocketW, as WSASocketA has been deprecated.
Fixed some warnings reported by Visual C++ 2013.
Fixed integer type used in the WinRT version of the byte-order conversion functions.
Changed documentation to indicate that use_future and spawn() are not made \ 
available when including the asio.hpp convenience header.
Explicitly marked asio::strand as deprecated. Use asio::io_service::strand instead.

Circular Buffer:
Fixed some warnings and move_if_noexcept from Boost.Move is used

Config:
BOOST_HAS_PRAGMA_DETECT_MISMATCH macro was added

Container:
Added support for initializer_list.
Fixed double destruction bugs in vector and backward expansion capable allocators.

Coroutine:
optionally register stacks with valgrind
10386 MSVC link error in asymmetric_coroutine.hpp: symbol already defined
10536 call to 'begin(...pull_coroutine< R > & c)' is ambiguous

Flyweight:
Added serialization support via Boost Serialization.
flyweight default constructor was made explicit in Boost 1.56, which introduces \ 
a regression in some initialization scenarios. The former non-explicit default \ 
constructor has been restored

Changes 1.56.0:
Modularization
Boost version control has migrated to a system using git submodules. This \ 
shouldn't make too much of a difference to users, although the directory \ 
structure is now a bit different.

Parts of some libraries have been moved into different modules, and several new \ 
modules have been extracted from existing code. All header paths should remain \ 
the same. The new modules are:

Assert:
Customizable assert macros. Maintained by Peter Dimov.
Core:
Core utilities used by other libraries, with minimal dependencies. Maintained by \ 
Peter Dimov, Glen Fernandes and Andrey Semashev.
Lexical_Cast:
General literal text conversions, such as an int represented a string, or \ 
vice-versa, from Kevlin Henney.
Throw_Exception:
A common infrastructure for throwing exceptions from Boost libraries, from Emil \ 
Dotchevski.
Winapi:
Windows API declarations without <windows.h>, for internal Boost use.
New Libraries
Align:
Memory alignment functions, allocators, and adaptors, from Glen Fernandes.
Type_Index:
Runtime/Compile time copyable type info, from Antony Polukhin.

Log message:
Put back BOOST_TARGET=darwin when using gcc, it breaks horribly otherwise.

Log message:
* Fix building with GCC (PR#48388).
* Build long double math libraries on NetBSD and FreeBSD.
* Removed obsolete patches.

Log message:
Changes 1.55.0:
Support was removed from Config for some very old versions of compilers. The new \ 
minimum requirements are:
Digitial Mars 8.41
GCC 3.3
Intel 6.0
Visual C++ 7.1
Other compilers are currently unchanged, but we are considering removing support \ 
for some other old compilers. Candidates for removal are:
Metroworks C++ (i.e. codewarrior)
SunPro 5.7 and earlier
Borland C++ Builder 2006 (5.82) and earlier
If you're using any of these, please let us know on the mailing lists. We will \ 
take into account any feedback received before making a decision.

Log message:
Changes 1.53.0:
New Libraries:
Atomic:
C++11-style atomic<>, from Helge Bahmann, maintained by Tim Blechmann.
Coroutine:
Coroutine library, from Oliver Kowalke.
Lockfree:
Lockfree data structures, from Tim Blechmann.
Multiprecision:
Extended precision arithmetic types for floating point, integer and rational \ 
arithmetic from John Maddock and Christopher Kormanyos.
Odeint:
Solving ordinary differential equations, from Karsten Ahnert and Mario Mulansky.
