+Subject: [PATCH] Migrate to boost::asio::io_context
+
+The code previously used the deprecated (and with bost 1.87.0 removed)
+`boost::asio::io_service`, which used to be an alias to `io_context`.
+The new version heavily changes the `io_context` API and therefore is no
+the old interface was removed.
