+[heading Asio 1.28.1 / Boost 1.83 beta]
+
+* 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 missing c++14 echo examples.
