Add experimental::as_tuple completion token adapter.
...
The as_tuple completion token adapter can be used to specify that the
completion handler arguments should be combined into a single tuple
argument.
The as_tuple adapter may be used in conjunction with use_awaitable and
structured bindings as follows:
auto [e, n] = co_await socket.async_read_some(
asio::buffer(data), as_tuple(use_awaitable));
Alternatively, it may be used as a default completion token like so:
using default_token = as_tuple_t<use_awaitable_t<>>;
using tcp_socket = default_token::as_default_on_t<tcp::socket>;
// ...
awaitable<void> do_read(tcp_socket socket)
{
// ...
auto [e, n] = co_await socket.async_read_some(asio::buffer(data));
// ...
}

Add associator trait.
...
The associator trait is used to generically forward associators, such as
associated_executor<> and associated_allocator<>, through intermediate
completion handlers. For example:
template <typename Handler>
struct intermediate_handler
{
Handler handler_;
template <typename... Args>
void operator()(Args&... args)
{
// ...
}
};
namespace boost {
namespace asio {
template <
template <typename, typename> class Associator,
typename Handler,
typename DefaultCandidate>
struct associator<
Associator,
intermediate_handler<Handler>,
DefaultCandidate>
{
using type =
typename Associator<Handler, DefaultCandidate>::type;
static type get(
const intermediate_handler<Handler>& h,
const DefaultCandidate& c = DefaultCandidate()) noexcept
{
return Associator<Handler, DefaultCandidate>::get(
h.handler_, c);
}
};
} // namespace asio
} // namespace boost

Increase number of cached memory slots for default recycling allocator.
...
The number of per-thread slots may be configured at compile time by
defining ASIO_RECYCLING_ALLOCATOR_CACHE_SIZE to a non-negative integer.
If not defined, the default recycling allocator uses two slots.

Make allocators respect alignment requirements.
...
This is important when completion handlers contain over-aligned members,
for example when captured in a lambda.
This uses operator new() with alignment support if available,
and falls back to Boost Align (again, if available).

Prevent blocking.always from being used with strand<>.
...
Previously, calling `require(E, blocking.always)` on a strand E compiled
but produced incorrect behaviour. Now, `require(E, blocking.always)`
will no longer compile. Furthermore, when used with an always-blocking
inner executor, the strand will report its blocking property as
blocking.possibly.

Fix outstanding_work.tracked executor move assignment.
...
Move assignments for io_context and thread pool executors are missing
the logic present in copy assignments that finishes work on old contexts.
This causes the following example to hang:
int main()
{
asio::static_thread_pool tp1{1},tp2{1};
{
auto work = asio::prefer(tp1.get_executor(),
asio::execution::outstanding_work.tracked);
work = asio::prefer(tp2.get_executor(),
asio::execution::outstanding_work.tracked);
}
tp1.join();
tp2.join();
