boost: updated to 1.82.0


New Libraries
a C++11 client for the MySQL database server, based on Boost.Asio, from Ruben Perez.
Updated Libraries
Now uses core/enable_if.hpp header instead of the deprecated utility/enable_if.hpp.
Added the ability to customise the execution of a completion handler when an \ 
operation completes immediately.
Added user-defined literals for buffer types.
Added a new protocol type local::seq_packet_protocol to represent AF_UNIX with \ 
Exposed sigaction() flags via an optional argument to signal_set::add.
Change allocator_binder, executor_binder, and cancellation_slot_binder to \ 
support detection of unspecialised associators.
Fixed ambiguity in associated_cancellation_slot<reference_wrapper>::get().
Fixed awaitable<> handling for completion signatures containing \ 
Fixed experimental::channel<> try_send failure after a cancel.

Ensured buffered messages can still be received when an \ 
experimental::channel<> is closed.
Fixed the any_completion_handler assignment operator.
Constrained the constructor of any_completion_handler to prevent accidental copying
Changed to use uint64_t for OpenSSL options, to match OpenSSL 3.
Fixed deferred interoperability with multiple completion signatures.
Fixed channels to add partial support for C++11 and C++14.
Added missing handler tracking source location support to co_composed and \ 
'awaitable<>' coroutines, when awaiting packaged asynchronous operations.
Fixed some 'potential null dereference' and shadow variable warnings.
Fixed a asio::buffer overload selection when used with const_buffers_1 and \ 
Disabled the runtime check for current Windows version unless targeting older \ 
Fixed compatibility between buffered stream wrappers and move-constructible \ 
streams, such as ssl::stream<>.
Fixed basic_socket_acceptor::async_accept compatibility with lambdas that have a \ 
deduced return type.
Fixed as_tuple compatibility with legacy completion tokens.
Fixed redirect_error compatibility with new completion tokens.
Fixed a potential, Windows-specific program termination due to exceptions that \ 
should have been allowed to escape from a destructor.
Prevented inadvertent co_await of boolean expressions.
Fixed result handling and support for custom allocators in experimental::use_coro.
Fixed variadic template emulation for is_async_operation and completion_signature_of.
Fixed incorrect reuse of a moved-from result in experimental::promise.
Fixed experimental::coro use with custom allocators.
Fixed seek_cur behaviour with stream-oriented files on Windows.
Various additions and modifications to the documentation.
Consult the Revision History for further details.
When compiled for x86 targets supporting AVX, vector instructions are now used \ 
for 128-bit atomic loads and stores.
For 32-bit x86 targets, 64-bit atomic loads and stores with memory_order_seq_cst \ 
semantics will now issue a memory ordering instruction.
Removed atomic<T>::storage() accessors and atomic<T>::storage_type \ 
types that were deprecated in Boost.Atomic 1.73. Users are recommended to use \ 
atomic<T>::value() and atomic<T>::value_type instead.
Add error_codes use source_location
tcp_stream uses the correct executor of the timer.
error_categories use numeric ids
file_body supports seek
Added an overload of hash_value for std::nullptr_t.
Added is_tuple_like and an overload of hash_value for tuple-like types.
Changed string hashing to use mulxp1_hash. This improves both quality and speed.
Added boost/core/snprintf.hpp header with portable definitions of snprintf, \ 
vsnprintf and their wchar_t counterparts.
Deprecated boost/core/is_same.hpp and boost::core::is_same. The header will be \ 
removed in a future release. Users are advised to use Boost.TypeTraits or C++ \ 
standard library type traits instead.
Marked boost::ref member functions and associated methods with noexcept.
Marked boost::swap function with noexcept, depending on whether the type \ 
supports a non-throwing swap operation.
Added boost::core::launder, a portable implementation of std::launder.
Added BOOST_CORE_ALIGNOF, a portable implementation of alignof.
Added boost::core::max_align_t, a portable equivalent of std::max_align_t, and \ 
boost::core::max_align, the alignment of max_align_t.
Added boost::core::memory_resource, a portable equivalent of \ 
std::pmr::memory_resource from C++17.
Added boost/core/serialization.hpp, a collection of primitives allowing \ 
libraries to implement Boost.Serialization support for their types without \ 
including a Serialization header and thereby making their libraries depend on \ 
Added boost::data, an implementation of std::data.
Added boost::size, an implementation of std::size.
Updated boost::span to use boost::data which adds support for range construction \ 
from an std::initializer_list.
Added boost::identity, an implementation of std::identity. This facility has \ 
been moved from Boost.Functional.
Avoid implicit cast from size_t to uint32_t
Fixed compilation errors that could have been caused by path conversion \ 
constructors being too permissive on the accepted arguments.
v4: path::remove_filename now presesrves the trailing directory separator.
Added path::remove_filename_and_trailing_separators, which removes the filename \ 
and directory separators preceding it from the path. This behavior is similar to \ 
path::remove_filename in Filesystem v3, but is also usable in v4.
Added path::replace_filename, which replaces filename in a path.
Updated implementation of the library version selection to avoid ODR violations.
On Windows, added a workaround for querying file attributes for files in SMBv1 \ 
shares. Previously, directories in SMBv1 shares could have been reported as \ 
regular files. This does not affect SMBv2 or later.
Major improvements
Support geographic buffer for (multi)linestrings and (multi)polygons
Comparable distance: Add support for dynamic geometries
Support covered_by() for box, geometry combinations
Solved issues
WKT: allow tabs and new lines
Fixes for union

The WKT output presentation of an empty polygon is now POLYGON() to make it \ 
consistent with other geometries
Replace detail::span and detail::make_span with implementations in boost::core
Documentation improvements
Protect usage of std::min and std::max in some cases, contributed by Han Jiang \ 
(min,max macros are illegially set by popular Windows headers so we need to work \ 
Added test to catch usage of unprotected min,max tokens in the library in the future
Fixes to support latest clang-14 and deduction guides in gcc-11+
boost::hash support.
Caller-provided serializer storage.
value_to supports missing elements for std::optional.
Fix parser suspend inside an escape character.
Make sentinel() return a unique pointer.
get_system_locale and dependents will now correctly favor LC_ALL over LC_CTYPE \ 
as defined by POSIX
utf8_codecvt::out returns partial for trailing (UTF) surrogates
Add boost::locale::util::locale_data to parse a locale
boost::locale::info::encoding() result is now in uppercase as documented, e.g. \

Treat en_US_POSIX as an alias for the C locale
Improve error for missing segmentation support (i.e. without ICU)
Fix compiler warnings
Deprecated C++11 support: We now require C++14 as a minimum standard. Our \ 
minimum tested compiler versions are now Clang-5, GCC-5 or MSVC-14.1.
Added Estrin's method for polynomial evaluation.
Fix various issues in non-central distributions to allow for larger \ 
non-centralities see 939.

not actually constexpr, see 923.
Improve tanh_sinh boundary handling, see 894.

long doubles.
Improve constexpr math functions to better handle infinities and NaN's.
Make the integrators const-correct.
Fix tanh_sinh integrator in case the function underflows, see 898.
Don't use std::cbrt as some platforms still don't support it.

Fix root finding edge cases, see 873.
Lots of miscellaneous warning fixes.
Add assertions when using features which require C++17 for better error messages \ 
when invoking the compiler in a lower std version.
Multi-index Containers:
Serialization now uses unsigned long instead of collection_size_type, and \ 
multi_index_container serialization class version has been bumped from 2 to 3 to \ 
reflect this change. Reading old archives may fail for custom archive types \ 
giving special treatment to collection_size_type values: if this is the case, \ 
globally define the macro \ 
compatibility in reading operations.
