1.29.0

asio update - chriskohlhoff/asio

• Changed to require C++11 as the minimum language standard.
• Removed deprecated functionality from the asio::execution namespace.
• Removed deprecated invocation and allocation hooks.
• Added compatibility between Asio's placeholders and std::bind.
• Added try_send_via_dispatch and try_send_n_via_dispatch functions to
  channels.
• Improved C++11 support for multi-signature channels.
• Fixed compatibility between channel asynchronous operations and
  any_completion_handler.
• Added missing equality operators for mixed property types belonging to the
  same category.
• Fixed an issue where spawn-based stackful coroutines would terminate the

  signature starting with std::exception_ptr.

1.28.2

zig-pkg update

• New minimum version: 0.12.0 - add basic git support

asio update - chriskohlhoff/asio

• Fixed the completion token adapters bind_allocator, bind_cancellation_slot
  and bind_immediate_executor to not require a return_type type alias in
  the adapted async_result specialisation.
• Fixed a potental crash due to an object lifetime issue in the co_spawn
  operation's cancellation support.
• Enabled compiler-supported thread locals on more target platforms, using the
  thread_local keyword if available.
• Fixed the documentation of the per-operation cancellation behaviour for
  experimental::co_composed to correctly state that terminal cancellation is
  enabled by default.
• Documented the per-operation cancellation behaviour of async_compose.
• Added bind_immediate_executor to the Completion Token Adapters overview.
• Added an example illustrating how to use an experimental channel for
  mutual exclusion between cooperating asynchronous actors.
• Added an example showing how to write a minimal completion executor.

1.28.1

asio update - chriskohlhoff/asio

• Added missing compatibility with associated_immediate_executor to
  any_completion_handler.
• Fixed a null pointer dereference that occurs when using query, require or
  prefer with an empty any_executor.
• Added a workaround in experimental::coro for a spurious syntax error when
  compiling with MSVC.
• Fixed an integer truncation issue in per-operation cancellation, when using
  the reactor backend on 64-bit Windows.
• Added a compile-time check for a minimum Linux kernel version of 5.10, when
  [^io_uring] support is enabled.
• Fixed a compile error in the converting move constructors for
  experimental::basic_channel and experimental::basic_concurrent_channel.
• Fixed a memory leak on some signal_set error handling code paths.
• Fixed bad_address_cast to not use a deprecated implicit copy constructor.
• Fixed a copy/paste error in the dev_poll_reactor backend.
• Fixed the [^io_uring] backend to ensure the internal timeout operations, used
  to implement io_context::run_for and io_context::run_until, are
  cleaned up correctly.
• Eliminated some duplicated state in the co_spawn implementation's entry
  point, reducing memory consumption.
• Added c++14 echo examples to boostify script.
