+- Adjust the flush to output ``SO_SNDBUF`` bytes instead of whatever was
+  set in the ``send_bytes`` adjustment. ``send_bytes`` now only controls how
+  much waitress will buffer internally before flushing to the kernel, whereas
+  previously it used to also throttle how much data was sent to the kernel.
+  This change enables a streaming ``app_iter`` containing small chunks to
+  still be flushed efficiently.

 - When a client closes a socket unexpectedly there was potential for memory
   leaks in which data was written to the buffers after they were closed,
   causing them to reopen.
