// ** Conform to `std::pointer_traits` requirements (boost_gh:pr[interprocess,32]).
// ** Fixed `named_condition_any` fails to notify (boost_gh:issue[interprocess,62]).
* boost_phrase:library[Asio,/libs/asio/]
** Added the `execution::inline_exception_handling` property to describe
what exception handling guarantees are made when execution occurs inline.
** Added `inline_executor`, which always executes the submitted function
inline.
** Changed the default candidate executor for `associated_executor` from
`system_executor` to `inline_executor`.
** Added the `inline_or_executor<>` adapter and `inline_or()` helper, which
will execute inline if possible and otherwise delegate to another executor.
** Added overloads of `dispatch`, `post` and `defer` that take a function
object to be run on the target executor, and deliver the result to the
completion handler.
** Added the `redirect_disposition` completion token adapter, as a generic
counterpart for `redirect_error`.
** Annotated deprecated items with the `+++[[+++deprecated+++]]+++` attribute.
** Added a new configuration parameter "reactor" /
"reset_edge_on_partial_read", which determines whether a partial read
consumes the edge when using `epoll`.
** Added new configuration parameters "reactor" / "use_eventfd" and "reactor"
/ "use_timerfd" that are used to determine whether the `epoll` backend
uses `eventfd` and `timerfd` respectively.
** Added the missing preprocessor check for `BOOST_ASIO_DISABLE_TIMERFD`.
** Implemented a compile-time feature check for `std::source_location`
support, in addition to `std::experimental::source_location`.
** Stopped using the deprecated `boost::array::c_array()` function.
** Fixed a resource leak in `asio::awaitable` move assignment.
** Fixed a memory leak in `ssl` stream move assignment.
** Fixed a thread sanitizer issue in `kqueue` reactor.
** Fixed handler tracking arguments in `io_uring` backend.
** Fixed an unused parameter warning in `boost::asio::detail::null_thread`.
** Changed the macro-based coroutine implementation to ensure deterministic case
labels when `+++__+++COUNTER+++__+++` is used.
** Fixed synchronous SSL stream `shutdown` to remap `error::eof` as
`async_shutdown` does.
** Changed `stream_file` and `random_access_file` on Windows to treat file
paths as UTF-8 encoded strings.
** Added checks to `experimental::parallel_group` and
`experimental::ranged_parallel_group` to detect empty operation sets.
** Removed workaround for `_FORTIFY_SOURCE`, added address length checking to
`ip::basic_resolver_results`.
** Fixed `experimental::coro` to have protection against `max` as a macro.
** Updated detection of `std::aligned_alloc` for newer `libc++` versions.
** Various documentation fixes and improvements.
** Consult the
boost_at:/doc/libs/1_90_0/doc/html/boost_asio/history.html[Revision
History] for further details.
* boost_phrase:library[Beast,/libs/beast/]:
** `http::parser` rejects non-standard trailer fields by default.
** `http::basic_parser` uses a dedicated callback for trailer fields.
