   Changes between 1.4a3 and 1.4a4 (29-Jul-2000 to 24-Mar-2001)
 
+   *) Implemented the pthread_{set,get}concurrency() API parts of
+      POSIX/SUSv2, although internally we are (allowed to be) free to not
+      do anything based on the requested level.
+      [Ralf S. Engelschall, Bill Apt <babt@us.ibm.com>]
+
    *) Adjusted all pthread_attr_getXXXX() functions to use a "const
       pthread_attr_t *" as the first argument instead of "pthread_attr_t
       *" to fully-conform to POSIX/SUSv2.
