Note about
the new Visual Studio release
Visual Studio 15.5 was released too late for us to test this release with it.
New Libraries
- Beast:
-
Portable HTTP, WebSocket,
and network operations using only C++11 and Boost.Asio, from Vinnie Falco.
- CallableTraits:
-
A spiritual
successor to Boost.FunctionTypes, Boost. is a header-only
C++11 library for the compile-time inspection and manipulation of all 'callable'
types. Additional support for C++17 features, from Barrett Adair.
- Mp11:
-
A C++11 metaprogramming library,
from Peter Dimov.
Updated Libraries
-
Asio:
-
Implemented interface changes to reflect the Networking TS (N4656).
-
See the list
of new interfaces and, where applicable, the corresponding
old interfaces that have been superseded.
-
The service template parameters, and the corresponding classes,
are disabled by default. For example, instead of
basic_socket<Protocol,
SocketService>
we now have simply basic_socket<Protocol>. The old interface can
be enabled by defining the BOOST_ASIO_ENABLE_OLD_SERVICES
macro.
-
Removed previously deprecated functions.
-
Added support for customised handler tracking.
-
Added reactor-related (i.e. descriptor readiness) events to handler
tracking.
-
Added special "concurrency hint" values that may be used
to disable locking on a per
io_context
basis.
-
Enabled perfect forwarding for the first
ssl::stream<> constructor argument.
-
Added ability to release ownership of the underlying native socket.
(Requires Windows 8.1 or later when using the I/O completion port
backend.)
-
Atomic:
-
Implemented a set of experimental extended atomic operations for
integral types:
-
fetch_negate,
fetch_complement
- atomically replaces the value with a negated or binary complemented
value and returns the original value
-
opaque_<op>
- equivalent to fetch_<op> except that it doesn't
return the original value
-
<op>_and_test
- atomically applies <op>
and returns true
if the result is zero. Note:
The result of these operations will change to the opposite
in Boost 1.67. The code that uses these functions will need
to be updated.
-
bit_test_and_set,
bit_test_and_reset,
bit_test_and_complement
- atomically sets, resets or complements the specified bit
and returns the original value of the bit
-
Following C++17 (P0558R1),
arithmetic operations for pointers to non-object types are no longer
provided.
-
Also following C++17 exposed
atomic<T>::value_type
and atomic<T>::difference_type member typedefs,
where applicable, to the user's code.
-
Improved compatibility with gcc 7. In particular, using 128-bit operations
on x86-64 should no longer require linking with libatomic (the compiler-supplied
library).
-
DateTime:
-
The library has been converted to use Boost.WinAPI as the abstraction
layer for Windows SDK.
-
Fixed an integral overflow that could cause incorrect results when
adding or subtracting many years from a date (see here).
-
Fiber:
-
synchronization with CUDA streams
-
synchronization with ROCm/HIP streams
-
Format:
-
Improvements:
-
Accept new conversion specifiers:
-
a: sets flags
fixed | scientific
(i.e. hexfloat)
-
b: sets flag
boolalpha
-
A: same as
a plus
flag uppercase
-
F: same as
f plus
flag uppercase
-
42
Accept new argument types
j
and z from
ISO C99 (parsed and ignored like all others).
-
44
Accept new argument types
I,
I32, I64, and w
from Microsoft (parsed and ignored like all others).
-
33
Added a development tool called
format_matrix
that exercises as many different combinations of format strings
as possible and logs them to a file:
-
helps prevent regressions in between boost releases
-
allows for comparison against
snprintf
-
Bugfixes:
-
36
Safely allow volatile arguments to be used with operator%
-
4636
Explicit clamping provided to allow MSVC /RTCc to succeed
-
7477
Fix compatibility with MSVC /Za
-
10324
Const-correct cast issue resolved
-
11632
Fix
-fsanitize=undefined
issue in alt_sstream.hpp
-
Fusion:
-
PR#149
isspace(c)
is not a macro in Dinkum clib for VxWorks, thanks to Brian Kuhl(@kuhlenough).
-
PR#150
Remove circular preprocessor include, thanks to Gregor Jasny(@gjasny).
-
PR#151
Change base of
fusion::tuple.
-
PR#153
Fixed compile error with
std::array.
-
PR#154
Fixed bugs nesting and copying on c++03.
-
Geometry:
-
Improvements:
-
Add distance for geographic PointLike/AnyGeometry.
-
Bugfixes:
-
Fixes in results of union/intersection/difference which could
be incorrect in very complex cases
-
Fixes in validity of union/intersection/difference/buffer
-
Fixes in set and relational operations for non-cartesian coordinate
systems.
-
Iterator:
-
next()/prior()
functions now support user's iterators that don't specify nested
types such as iterator_category,
difference_type,
etc. and instead specialize std::iterator_traits
to define those types. The compiler must support C++17-compatible
std::iterator_traits for this to work.
-
Log:
-
Bug fixes:
-
Fixed a bug in
file_collector::scan_for_files
that could cause incorrectly named log files in the target
directory after the user's application restart.
-
See changelog
for more details.
-
Math:
-
New Features:
-
Add Gauss and Gauss-Kronrod quadrature routines.
-
Add double-exponential (tanh-sinh, exp-sinh and sinh-sinh)
quadrature routines.
-
Add Chebyshev polynomial evaluation, roots, integration, differentiation,
and interpolation routines.
-
Multi-index Containers:
-
Optional:
-
On newer compilers
optional
is now trivially-copyable for scalar Ts.
This uses a different storage (just T
rather than aligned_storage).
We require the compiler to support defaulted functions.
-
Changed the implementation of
operator== to get rid of the -Wmaybe-uninitialized
false-positive warning from GCC.
-
PolyCollection:
-
Boost.PolyCollection has been backported to GCC 4.8 to 4.9 and Clang
3.3 to 3.6. The version of libstdc++-v3 shipped with GCC 4.8 (which
can also be used by Clang) has deficiencies that result in the following
limitations when using Boost.PolyCollection:
-
Stateful allocators are not properly supported.
-
Allocator-extended move construction decays to allocator-extended
copy construction.
-
Copy construction crashes if an exception is thrown during
element copying.
-
Maintenance fixes.
-
Predef:
-
Improved Windows Universal Platform detection. (from James E. King,
III)
-
Add detection for CloudABI with cloudlibc. (from James E. King, III)
-
Various other bug fixes.
-
Regex:
-
Bug fixes:
-
Numerous small fixes for security issues discovered by de-fuzzing.
-
Stacktrace:
-
Now works out-of-the-box on MinGW-w64.
-
Now works on MinGW (without
-w64) if libbacktrace
is properly installed. See "MinGW specific notes" section
in documentation for more info.

make it easier to support whatever becomes the next standard
hash algorithm.

changes needed to user's code, however you may get build warnings
if you use the old header location.
-
Variant:
-
boost::apply_visitor now does perfect
forwarding of visitables #6971. Great thanks to Levon Tarakchyan
