@@ -15,6 +15,17 @@ Major new features:
 
 * New locale added: ckb_IQ (Kurdish/Sorani spoken in Iraq)
 
+* Support for Synopsys ARC HS cores (ARCv2 ISA) running Linux has been
+  added. This port requires at least binutils-2.32, gcc-8.3 and Linux-5.1.
+  Three ABIs are supported:
+
+     - arc-linux-gnu
+     - arc-linux-gnuhf
+     - arceb-linux-gnu
+
+  The arc* ABI is little-endian while arceb is big-endian. All ABIs use
+  64-bit time (y2038 safe) and 64-bit file offsets (LFS default).
+
 * The GNU C Library now loads audit modules listed in the DT_AUDIT and
   DT_DEPAUDIT dynamic section entries of the main executable.
