   The OpenRISC ABI is 32-bit big-endian and uses 64-bit time (y2038 safe) and
   64-bit file offsets (LFS default).
 
+* The functions posix_spawnattr_tcsetpgrp_np and posix_spawnattr_tcgetpgrp_np
+  have been added, enabling posix_spawn and posix_spawnp to set the
+  controlling terminal in the new process in a non race manner.  These
+  functions are GNU extensions.

 Deprecated and removed features, and other changes affecting compatibility:
 
 * On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support
