         - Lanes is implemented in C++20: thread, condition_variable, mutex, string_view, variant, lambdas, templates, and more!
         - Almost all platform-specific code is gone (only a small bit for thread priority and affinity remains).

             - New __close metamethod that calls join().
-            - lane:join()
-                - Returns nil, error in case of problem.
-                - Forces lane function body must return a non-nil first value on success because of the above.
+            - lane:join() returns nil, error in case of problem, else returns true followed by the lane body return values.
             - lane:get_debug_threadname() renamed get_threadname().
-            - cancel_test() returns "soft"/"hard" instead of true when a cancellation request is active
