New Libraries

    Variant2: A never-valueless, strong guarantee implementation of \ 
std::variant, from Peter Dimov.

Updated Libraries

    Align:
        Support for any integral type in the integral versions of align_up and \ 
align_down.
        Revised the implementation of aligned_allocator to no longer require a \ 
specialization for void.
        Define propagate_on_container_move_assignment and is_always_equal in \ 
aligned_allocator.
    Asio:
        Improved performance slightly by eliminating a redundant move \ 
construction when completed handlers are dispatched.
        Eliminated a compiler warning by annotating a case fall-through in the \ 
free function connect() implementation.
        Fixed the is_*_buffer_sequence detection traits for user-defined \ 
sequence types.
        Fixed some Windows-specific warnings about an incompatible pointer cast \ 
when obtaining the CancelIoEx entry point.
        Changed to automatically set the defaults when opening a serial port on \ 
Windows.
        Changed the serial port get_option() member function to be const.
        Fixed a name hiding issue with the WinRT stream-oriented socket \ 
backend's shutdown function.
        Applied a minor fix to the documentation for is_dynamic_buffer.
        Added some support for Haiku OS.
        Added wolfSSL compatability.
        Changed to require C++17 or later for coroutines TS support with clang.
        Fixed a doxygen generation problem in the tutorial.
        Ensured example programs are correctly incorporated into the documentation.
    Any:
        Static initialization of the default constructed boost::any is now possible.
        Fixed performance regression in assignment on a compilers without \ 
move-semantics.
        Maintenance work.
    Beast:
        This version consists mostly of bug fixes and performance improvements.
        Substantial work included for the split compilation mode, to reduce \ 
compile time when defining BOOST_BEAST_SEPARATE_COMPILATION.
        We'd love to know how you or your company use Beast, consider adding an \ 
item to the Companies and Individuals Using Beast list.
        See the full Release Notes for a complete list of changes.
    Circular Buffer:
        Correct doxygen generated reference to no longer show internal members. \ 
(Glen Fernandes)
        Eliminate ubsan warning on add and sub. (Glen Fernandes)
        Fix incorrect check in is_uninitialized. (Niklas Fejes)
    Container:
        Fixed bugs:
            GitHub #47: "added alignment specification for small_vector".
            GitHub #88: "Implement C++17 MoveAssignable requirements for \ 
self-move assignments".
            GitHub #107: "Alignment ignored in resource_adaptor".
            GitHub #109: "Get rid of integer overflow in copy_move_algo.hpp \

            GitHub #110: "Avoid gcc 9 deprecated copy warnings in \ 
new_allocator.hpp".
            GitHub #112: "vector::resize() compilation error with \ 
msvc-10..12: data is not a member of boost::detail::aligned_storage".
            GitHub #114: "Fix small_vector noexcept specification".
            GitHub #116: "MSVC + boost 1.70 compilation error when \ 
windows.h is already included (detail/thread_mutex.hpp)".
            GitHub #117: "flat_map/map::insert_or_assign with hint has \ 
wrong return types".
            GitHub #118: "Non-unique inplace_set_difference used in in \ 
flat_tree_merge_unique and iterator invalidation in insert_unique".
            GitHub #122: "Fix has_trivial_destructor_after_move".
            GitHub #123: "With heterogeneous lookup, equal_range can result \

        small_vector can now have options, using small_vector_options. Alignment \ 
and growth factor can be be specified.
    Context:
        Add support for RISC-V LP64D
        #72: Fix ABI violation on ppc64 ELFv2
        #99: cleanup of stack if creating ucontext fails
    Conversion:
        Maintenance work.
    Core:
        Added functions alloc_construct, alloc_construct_n, alloc_destroy, and \ 
alloc_destroy_n in <boost/core/alloc_construct.hpp> for allocator aware \ 
and exception safe construction and destruction of objects and arrays. (Glen \ 
Fernandes)
        Added constexpr functions first_scalar in \ 
<boost/core/first_scalar.hpp> for obtaining a pointer to the first scalar \ 
element of an array. Given a pointer of type T* they return a pointer of type \ 
remove_all_extents_t<T>*. (Glen Fernandes)
        Added class template noinit_adaptor in \ 
<boost/core/noinit_adaptor.hpp> which is an allocator adaptor that \ 
converts any allocator into one whose construct(ptr) performs default \ 
initialization via placement new, and whose destroy(ptr) invokes the value_type \ 
destructor directly. (Glen Fernandes)
        Added class template default_allocator in \ 
<boost/core/default_allocator.hpp>, which can serve as a minimal default \ 
allocator that has interface similar to C++20 std::allocator, supports \ 
configurations with disabled exceptions and does not have std as an associated \ 
namespace. The allocator uses operator new and operator delete for allocation. \ 
(Glen Fernandes)
        In <boost/core/uncaught_exceptions.hpp> header, added workarounds \ 
for better compatibility with QNX SDP 7.0 when libc++/libc++abi libraries are \ 
used. (Andrey Semashev, #59)
        The <boost/detail/sp_typeinfo.hpp> header is now marked as \ 
deprecated and will be removed in a future release. \ 
<boost/core/typeinfo.hpp> should be used instead. (Peter Dimov)
    Dynamic Bitset:
        Enabled hardware-assisted popcount on MSVC (#38).
        Added support for boost::hash and std::hash (#45).
        Support copy-initialization with default constructor (#48).
    Endian:
        Clarified requirements on the value type template parameter
        Added support for float and double
        Added endian_load, endian_store
        Updated endian_reverse to correctly support all non-bool integral types
        Moved deprecated names to the deprecated header endian.hpp
    Fiber:
        documentation for shared_work updated
    Filesystem:
        Fixed incorrect error_code returned from directory iterator increment \ 
when readdir_r is used.
        For path, fixed rvalue-aware operator/ return type to return an rvalue \ 
instead of rvalue reference. This fixes leaving a dangling reference in the \ 
user's code if the result of operator/ is bound to a const reference. (#110)
        Fixes for better compatibility with Windows CE. (#24)
        Added minimal support for CMake. (#106)
    Flyweight:
        Maintenance work.
    Histogram:
        New features:
            Support for thread-safe storages and new thread-safe accumulators
            Support for compiling without exceptions/RTTI (increases performance \ 
by 10-20 %) (with Glen Fernandes)
            Performance improvements for 1D and 2D histograms
            boost::histogram::indexed now returns forward iterator range instead \ 
of input iterator range
            boost::histogram::indexed_range::accessor is now non-copyable and \ 
acts like reference to cell value, making more algorithms from the C++ stdlib \ 
work
            boost::histogram::algorithm::reduce with new slice option and option \ 
fusion
            boost::histogram::algorithm::project accepts runtime indices for \ 
static histograms
        Bug Fixes:
            boost::histogram::algorithm::reduce also works on histograms that \ 
have some axis types without reduction support
            boost::histogram::axis::traits::update now works correctly for \ 
boost::histogram::axis::variant
        Other:
            100 % test coverage
            Reduced internal Boost dependencies
            Improved documentation and examples
            Guaranteed no-throw moves for all builtin axis types
            Compile cleanly at higher warning levels
        See changelog for more details.
    IoStreams:
        Fixed processing of multi-stream files (#87).
        Added support for multi-threaded LZMA (#95).
    Interprocess:
        GitHub #85 ("warning: Implicit conversion loses integer \ 
precision").
        GitHub #86 ("warning: Possible misuse of comma operator").
    Intrusive:
        GitHub #42: Documentation does not describe treap priority_of_value changes
        GitHub #43: Fix tests with BOOST_INTRUSIVE_VARIADIC_TEMPLATES enabled
        GitHub #45: Disable variadic templates for MSVC-12 to avoid ICEs
    LexicalCast:
        Added tests for boost::filesystem::path conversions #25.
        Maintenance work, including #28.
    Log:
        New features:
            Improved support for C++17 std::string_view in \ 
basic_formatting_ostream. The string view can now participate in character code \ 
conversion on output.
            Added auto_newline formatter and stream manipulator. It can be used \ 
to ensure that formatted output always ends with a newline while avoiding \ 
duplicate newlines.
            In the output stream, text file and text multi-file sink backends \ 
added support for configuring behavior with regard to appending a trailing \ 
newline to every formatted log record. Use auto_newline_mode named parameter of \ 
the backend constructor or call the set_auto_newline_mode method on the sink \ 
backend.
            Note: The default behavior with regard to trailing newlines added by \ 
sink backends has changed slightly compared to the previous Boost.Log releases. \ 
The backends will now only add a trailing newline if there isn't one in the \ 
formatted log message string already. In previous releases a newline was added \ 
unconditionally.
            Added support for passing arbitrary function objects in the filter \ 
and format named parameters to sink constructors and convenience functions for \ 
initializing sinks. For example, it is now possible to specify C++11 lambda \ 
functions directly in these parameters. (#63)
            In the default filter and formatter factories used in filter and \ 
formatter parsers, added support for severity level attribute values of type \ 
boost::log::trivial::severity_level. For filters, the support is limited to \ 
attributes with "Severity" name.
        Bug fixes:
            Fixed incorrect parsing of components of the rotated file names \ 
while scanning for files in the text file sink backend. If the file name pattern \ 
ended with a placeholder (for example, a file counter), the scan_for_files \ 
method would not find files matching that pattern in the target storage, leaving \ 
them unmanaged. In particular, such files would not be deleted to free target \ 
storage. (#78)
            Updated basic_formatting_ostream and basic_record_ostream to make it \ 
possible to overload stream output operators for pointers to user-defined types. \ 
User-defined operator<< overloads taking std::basic_ostream and a pointer \ 
argument should now be picked up by the compiler when the pointer is being \ 
written to one of Boost.Log streams. (#84)
        See changelog for more details.
    Math:
        New features:
            Catmull-Rom interpolator now works in C++11
            Cardinal quadratic B-spline interpolation
            Domain of elliptic integrals extended
            sin_pi and cos_pi performance improvements
            Forward-mode automatic differentiation
            Vector valued barycentric rational interpolation
            Ooura's method for evaluation of Fourier integrals
        Bug fixes:
            Multiple compatibility issues with Multiprecision fixed
            Lambert-W fixed on a rare architecture
    Metaparse:
        New features:
            In C++11 variadic template support for the following: sequence, \ 
one_of_c, one_of, repeated_one_of, repeated_one_of1, one_char_except_c, \ 
one_char_except.
        Bug fixes:
            BOOST_METAPARSE_STRING does not use out of range character values as \ 
template arguments.
            any_of_c<> does not create empty array in C++14.
    Move:
        Git Issue #26: "Invalid iterator increment/decrement in the last \ 
iteration of adaptive_sort_combine_blocks".
    Multi Array:
        Simplify allocator support by using new alloc_construct_n and \ 
alloc_destroy_n facilities from Core. (Glen Fernandes)
    Multi-index Containers:
        Added variants of const_mem_fun and mem_fun for differently qualified \ 
member functions (issue #24).
        Terse key specification syntax now correctly handles noexcept-specified \ 
member functions (issue #24).
    Outcome:
        Enhancements:
            #184 As per request from Boost release managers, relocated \ 
version.hpp and revision.hpp into detail, and added the Boost licence \ 
boilerplate to the top of every source file which was missing one (I think). \ 
Also took the opportunity to run the licence restamping script over all Outcome, \ 
so copyright dates are now up to date.
            #185 Add FAQ item explaining issue #185, and why we will do nothing \ 
to fix it right now.
            #189 Refactored the OUTCOME_TRY implementation to use more clarified \ 
customisation points capable of accepting very foreign inputs. Removed the \ 
std::experimental::expected<T, E> specialisations, as those are no longer \ 
necessary. Fixed the documentation for the customisation points which previously \ 
claimed that they are ADL discovered, which they are not. Added a recipe \ 
describing how to add in support for foreign input types.
            #183 Added a separate motivation/plug_error_code specifically for Boost.
        Bug fixes:
            OUTCOME_VERSION_MINOR hadn't been updated to 1.
            #181 Fix issue #181 where Outcome didn't actually implement the \ 
strong swap guarantee, despite being documented as doing so.
            #190 Fix issue #190 in Boost edition where unit test suite was not \ 
runnable from the Boost release distro.
            #182 Fix issue #182 where trait::is_exception_ptr_available<T> \ 
was always true, thus causing much weirdness, like not printing diagnostics and \ 
trying to feed everything to make_exception_ptr().
            #192 Fix issue #192 where the \ 
std::basic_outcome_failure_exception_from_error() was being defined twice for \ 
translation units which combine standalone and Boost Outcome's.
    Parameter:
        Upgraded keyword generation macro BOOST_PARAMETER_TEMPLATE_KEYWORD (#15).
        Moved keyword generation macro BOOST_PARAMETER_NESTED_KEYWORD from \ 
Accumulators to this library (#28).
        Added support for std::reference_wrapper and std::ref() (#16).
        Moved boost::parameter::required, boost::parameter::optional, and \ 
boost::parameter::deduced metafunction definitions to their own header files in \ 
directory boost/parameter (#18).
        Added support for Boost.Parameter-enabled function call operators (#20).
        Added support for parameter category qualifiers "forward", \ 
"consume", and "move_from" (current qualifiers are \ 
"in", "out", and "in_out") (#21) (#23) based on \ 
http://www.modernescpp.com/index.php/c- … arameters. \ 
Added new usage syntax BOOST_PARAMETER_NAME((object-name), namespace-name) \ 
qualifier(tag-name)) and BOOST_PARAMETER_NAME(qualifier(name)). (Existing code \ 
that uses qualifiers directly and correctly with BOOST_PARAMETER_FUNCTION and \ 
other code generation macros should remain unaffected for now, so no breaking \ 
changes.) The reason for the change in usage is to enable applying of parameter \ 
category constraints to Boost.Parameter-enabled functions and constructors \ 
invoked through argument composition. (Otherwise, it is currently possible to \ 
use argument composition to bypass parameter category constraints applied in \ 
BOOST_PARAMETER_FUNCTION et. al.)
        Added support for perfect forwarding (#23) (#26), so that \ 
parameter::parameters::operator() can accept non-const rvalues. As a positive \ 
side effect, Boost.Parameter-enabled functions and constructors are no longer \ 
bound by BOOST_PARAMETER_MAX_ARITY on compilers that support perfect forwarding. \ 
User code can now check for this support by detecting the configuration macro \ 
BOOST_PARAMETER_HAS_PERFECT_FORWARDING, or manually turn off this support by \ 
defining the configuration macro BOOST_PARAMETER_DISABLE_PERFECT_FORWARDING.
        Added metafunctions boost::parameter::is_argument_pack (#27), \ 
boost::parameter::are_tagged_arguments (#52), and \ 
boost::parameter::result_of::compose (#75).
        Added variadic function template boost::parameter::compose() which takes \ 
in named arguments and returns them in an argument pack (#52). For compilers \ 
that do not support perfect forwarding, the configuration macro \ 
BOOST_PARAMETER_COMPOSE_MAX_ARITY determines the maximum number of arguments \ 
that boost::parameter::compose() can take in (#61).
        Added code generation macros \ 
BOOST_PARAMETER_BASIC_FUNCTION_CALL_OPERATOR, \ 
BOOST_PARAMETER_BASIC_CONST_FUNCTION_CALL_OPERATOR, \ 
BOOST_PARAMETER_NO_SPEC_FUNCTION, BOOST_PARAMETER_NO_SPEC_MEMBER_FUNCTION, \ 
BOOST_PARAMETER_NO_SPEC_CONST_MEMBER_FUNCTION, \ 
BOOST_PARAMETER_NO_SPEC_FUNCTION_CALL_OPERATOR, \ 
BOOST_PARAMETER_NO_SPEC_CONST_FUNCTION_CALL_OPERATOR, \ 
BOOST_PARAMETER_NO_SPEC_CONSTRUCTOR, and \ 
BOOST_PARAMETER_NO_SPEC_NO_BASE_CONSTRUCTOR (#52).
        Added support for Boost.MP11 (#47) (#66) (#70). User code can now check \ 
for this support by detecting the configuration macro \ 
BOOST_PARAMETER_CAN_USE_MP11, or manually turn off this support by defining the \ 
configuration macro BOOST_PARAMETER_DISABLE_MP11_USAGE.
        Improved support for parameter-dependent return types via SFINAE (#73).
    PtrContainer:
        Fix a ptr_vector regression introduced in 1.66.0 (#24).
    PolyCollection:
        Maintenance work.
    SmartPtr:
        Added aliasing constructors to weak_ptr
        Added weak_ptr<T>::empty()
        Added enable_shared_from, shared_from, and weak_from
    Stacktrace:
        Fixed output of name(), source_location() and source_line() for the \ 
default constructed frame with thread sanitizer builds in C++98 mode.
        Fixed output of long strings from name() and source_location() on MSVC #78.
        Maintenance work.
    Test:
        Boost.test v3.11 see the Changes log for more details.
        Breaking changes:
            Boost.Test shows deprecation warnings if some very old headers as \ 
deprecated. If you encounter such warnings, please follow the indications: those \ 
headers will be removed in a future release.
        New feature:
            Now BOOST_TEST can be used to compare abstract types
        Bug fixes and pull requests:
            GitHub Issues: #209, #218
            GitHub Pull Requests: #219, #224
    Utility:
        Implemented function template ostream_string in \ 
<boost/utility/ostream_string.hpp> to optimally write any kind of string \ 
content to an output stream. It satisfies the requirements of \ 
[ostream.formatted.reqmts]. (Glen Fernandes)
        Optimized the stream output operators of basic_string_view and \ 
basic_string_ref to write directly to the rdbuf stream buffer. (Glen Fernandes)
    Uuid:
        Breaking change: MD5 name-based uuid generation was corrected to be \ 
identical on all endian systems. Define BOOST_UUID_COMPAT_PRE_1_71_MD5 to keep \ 
the result in a format compatible with 1.66 through 1.70. This does not affect \ 
the default name-based uuid generation which is based on SHA1. (#109)
    Variant:
        Fixed compilation of boost::apply_visitor with variants passed by non \ 
const reference in #68. Many thanks to Ed Catmur for providing the fix.
        Added support for std::hash (#49). Macro \ 
BOOST_VARIANT_DO_NOT_SPECIALIZE_STD_HASH could be defined to avoid those \ 
specializations.
        Added micro optimizations for binary size and performance by Nikita \ 
Kniazev in #63 and #66.
        Maintenance work, including #64 by Nikita Kniazev and #67 by Hans Dembinski.
    YAP:
        Added an example showing how to make self-evaluating YAP expressions \ 
(that is, expressions that don't need an explicit call to evaluate() or \ 
transform()).

Updated Libraries

    Asio:
        This release includes a number of new features, bug fixes, performance \ 
enhancements, and documentation improvements. Notable changes include:
            Added the ability to use custom I/O executors with I/O objects (such \ 
as sockets).
            Added a new async_result form with an initiate static member function.
            Updated the Coroutines TS support and promoted it to the asio namespace.
            Added a new DynamicBuffer_v2 concept which is CopyConstructible.
            Added a new async_compose function that simplifies the \ 
implementation of user-defined asynchronous operations.
            Added a make_strand helper function.
            Relaxed the completion condition type requirements to only require \ 
move-constructibility rather than copy-constructibility.
            Added a constructor for local::basic_endpoint that takes a string_view.
            Added the noexcept qualifier to various functions.
            Added a new BOOST_ASIO_DISABLE_VISIBILITY configuration #define.
            Enabled recycling of the memory used to type-erase a function object \ 
with the polymorphic executor.
            Changed receive operations to return the correct number of bytes \ 
transferred when truncation (error::message_size) occurs on a datagram-oriented \ 
socket.
            Fixed calculation of absolute timeout when the backend uses \ 
pthread_cond_timedwait.
            Changed the range-based asynchronous connect operation to deduce the \ 
EndpointSequence iterator type.
            Fixed buffer_sequence_begin and buffer_sequence_end to prevent \ 
implicit conversion.
            Ensured SSL handshake errors are propagated to the peer before the \ 
local operation completes.
            Suppressed the eof error on SSL shutdown as it actually indicates \ 
success.
            Added a fallback error code for when we OpenSSL produces an \ 
SSL_ERROR_SYSCALL result without an associated error.
            Changed composed asynchronous read and write operations to move \ 
buffer sequence objects.
            Fixed a macOS-specific warning about the deprecation of OSMemoryBarrier.
            Fixed compile errors that occur when using the composed read and \ 
write operations with MSVC 11.0.
            Improved dispatch, post and defer documentation.
            Fixed a Windows-specific memory leak that may occur when \ 
system_executor is used.
        Consult the Revision History for further details.

    Context:
        #91: cleanup of stack if creating ucontext fails
        #97: add missing BOST_CONTEXT_DECL in stack_context
        #98: fix jump_i386_sysv_macho writing garbage to the x87 control word
    Coroutine2:
        #28: don't crash on pthread_cancel
    DLL:
        New macro BOOST_DLL_USE_STD_FS. Define it to 1 to make the Boost.DLL use \ 
C++17's std::filesystem::path, std::system_error and std::error_code (#21). Note \ 
that exception types change from boost::system::system_error to \ 
std::system_error, so make sure to update catches.
        Significant rewrite of the dynamic loadable detection and decoration \ 
logic. More precise errors are now reported in case of loading failures. Added \ 
shared_library::decorate() function that returns a decorated path to the library \ 
without doing any platform related queries and detections. Prefer using \ 
shared_library::load and shared_library constructors for better results (many \ 
thanks to Loïc Touraine for the work PR#23).
        CI hardening, docs updates, typos fixes, cleanups and mg
        #196: fix high contention on remote_ready_splk_
    Filesystem:
        Fixed a few instances of dereferencing std::string::end() in path \ 
implementation.
        Fixed program termination in case of out of memory condition in \ 
directory iteratorsnce to error_code. (#58)
        Fixed possible linking errors caused by missing definitions of static \ 
members of path. (#12759)
        Fixed possible use of uninitialized data in directory iterator increment \ 
operation on Linux.
        Added support fortatus query overloads for directory_entry. This avoids \ 
a relatively expensive OS query when file status is requested for a result of \ 
dereferencing a directory iterator. (PR#55)
        Reworked current_path and read_symlink implementation to avoid \ 
possiblfilesystems. The functions now have an internal limit of the path size \ 
they will accept from the OS, which is currently 16 MiB.
        Increased the size of the internal buffer used by copy_file.
    Integer:
        Added Extended Euclidean Algorithm and Modular Multiplicative Inverse \ 
function. (Nick Thompson, PR#11)
    Log:
        New features:
            Added support for generating another log file name before collecting \ 
the file in the text file sink backend. This allows to combine appending to \ 
aexisting log file with timestamps and file counters in log filenames, and, \ 
consequently, file collection in general.
        See changelog for more details.
    Math:
        New features:
            Add Lanczos smoothing derivatives
            Move numols/ to boost/math/differentiation/finite_difference.hpp.
            Add mean, variance, skewness, kurtosis, median, Gini coefficient, \ 
and median absolute deviation to tools/univariate_statistics.hpp.
            Add correlation coefficients and covariand absolute Gini \ 
coefficient, Hoyer sparsity, oracle SNR, and the M[sub 2]M[sub 4] SNR estimator \ 
to tools/signal_statistics.hpp.
            Add total variation, l0, l1, l2, and sup norms, as well as \ 
corresponding distance functions to tools/norms.hpp.
   for polynomials, support complex coefficients, add .prime() and .integrate() \ 
methods.
            Add quadratic_roots to tools/roots.hpp.
            Add support for complex-valued functions to Newton's method in roots.hpp.
            Add Catmull-Rom inted mp_invoke to mp_invoke_q
        Added mp_similar
        Added mp_set_union, mp_set_intersection, mp_set_difference
        Added mp_not_fn
        Added mp_transform_first, mp_transform_second, mp_transform_third
        Added mp_filter
        Addedp_valid_q
        Added mp_back, mp_pop_back
    Multi-index Containers:
        size_type and difference_type are now defined as the allocator's \ 
same-named types. This will not make any difference in the vast majority of \ 
cases, but allows for some degreevia user-defined allocator types (see issue #17 \ 
for motivation). For the moment being, this change is not documented in the \ 
reference section (i.e., it has semi-official status).
        Maintenance work.
    Multiprecision:
        Fix various conversioncheck for compatibility with Boost.Optional.
        Prevent instantiation of std::numeric_limits on any old type when \ 
checking for convertibility. See #98.
        Update variable precision code to account for arbitrary precision \ 
integers. See #103.
    lization archives.
        Fix bug in fixed precision iostream formatting in mpf_float and \ 
mpfr_float. See #113.
        Add more overloads for special functions which are better handled \ 
natively by MPFR.
        Fixed bug in generic exp implementation wh.
        Fixed generic conversion from float to integer to avoid undefined \ 
behaviour. See #110.
    PolyCollection:
        Improved handling of stateful allocators and allocator propagation \ 
traits, after an error reported by Billy O'Neal (PR#9).
       ug with an internal cache structure.
    Spirit:
        Removed use of deprecated boost/detail/iterator.hpp header. PR#432
        X3

std::numeric_limits<T>::is_bounded instead of \ 
boost::integer_traits<T>::is_integral.
            Removed sequence into plain parsing. Now it triggers a compile time \ 
error instead of silently parsing the the sequence and taking the last value as \ 
a resulte_rule instantiation with BOOST_SPIRIT_INSTANTIATE when:
                A rule has no attribute. PR#455
                An actual attribute is not of type a rule was declared with. \ 
PR#456 #457
            A huge thanks goes out to Xeverous for reporting    Fixed unneded \ 
attribute synthesization and no-transformation attribute reference pass-through \ 
in rules. #444 PR#449 PR#452
            Removed broken 1.0#INF parser. It was poorly documented and never \ 
worked. #415 PR#458 #8699
            The undocumenoved due to bugs PR#449 and to simplify attribute \ 
transformation. PR#460
            If you were using it to workaround bugs in attribute transformation \ 
- they should not be needed anymore as of this release.
            The integer value parser now respe10 value. PR#469
            Fixed underflow check for a (Min % Base) == 0 corner case. PR#469
            Fixed an output value on overflow of IgnoreOverflowDigits=true \ 
integer parser. PR#470
            Container attribute elements were copyied, but notial handling of \ 
references in transform_attribute was removed. PR#480
        V2
            Macro name collisions and namespace conflicts with Boost.Endian were \ 
fixed. PR#349 PR#482
            utree
                Fixed UB in tag getter due to left shi            Fixed \ 
double-conversion (spirit::string -> std::string -> spirit::string). \

reoost::integer_traits<T>::is_integral PR#429
                Integer parsers should now handle user defined types. PR#429
                Note: The check_overflow trait default implementation now relies \ 
on std::numeric_limits<T>::is_bounded instead of boosl.
                Removed broken 1.0#INF parser. It was poorly documented and \ 
never worked. #415 PR#458 #8699
                The undocumented make_attribute trait was merged into \ 
transform_attribute trait. PR#471
                The pre_transform, post_tility functions were removed in favor \ 
of directly using pre/post/fail of the transform trait. PR#467
                The integer value parser now respects \ 
std::numeric_limits<T>::digits10 value. PR#469
                Fixed underflow check for a (Min % B            Fixed an output \ 
value on overflow of IgnoreOverflowDigits=true integer parser. PR#470
                Special handling of references in transform_attribute was \ 
removed. PR#480
            Lex
                Fixed UB in default constructor of ken type. PR#420
        Classic:
            Fixed position_iterator forming reference to local when the \ 
underlying iterator dereference operator returns a non-reference type. PR#422 \ 
#9737
