* 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.
