+* Add support for the new discriminator column in the DWARF line table,
+  with a discriminator operand for the .loc directive.
+
+* Add support for Sunplus score architecture.
+
+* The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
+  indicate that if the symbol is the target of a relocation, its value should
+  not be use.  Instead the function should be invoked and its result used as
+  the value.
+ 
+* Add support for Lattice Mico32 (lm32) architecture.
+
+Changes in 2.19:
+
+* New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
+  tables without runtime relocation.
+
+* New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
+  adds compatibility with H'00 style hex constants.
+
+* New command line option, -msse-check=[none|error|warning], for x86
+  targets.
+
+* New sub-option added to the assembler's -a command line switch to
+  generate a listing output.  The 'g' sub-option will insert into the listing
+  various information about the assembly, such as assembler version, the
+  command line options used, and a time stamp.
+
+* New command line option -msse2avx for x86 target to encode SSE
+  instructions with VEX prefix.
+
+* Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
+
+* New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
+  -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
+  -mnaked-reg and -mold-gcc, for x86 targets.
+
+* Support for generating wide character strings has been added via the new
+  pseudo ops: .string16, .string32 and .string64.
+
+* Support for SSE5 has been added to the i386 port.
+
+Changes in 2.18:
+
+* The GAS sources are now released under the GPLv3.
+
+* Support for the National Semiconductor CR16 target has been added.
+
+* Added gas .reloc pseudo.  This is a low-level interface for creating
+  relocations.
+
+* Add support for x86_64 PE+ target.
+
+* Add support for Score target.
+
+Changes in 2.17:
+
+* Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
+
+* Support for ms2 architecture has been added.
+
+* Support for the Z80 processor family has been added.
+
+* Add support for the "@<file>" syntax to the command line, so that extra
+  switches can be read from <file>.
+
+* The SH target supports a new command line switch --enable-reg-prefix which,
+  if enabled, will allow register names to be optionally prefixed with a $
+  character.  This allows register names to be distinguished from label names.
+  
 * Macros with a variable number of arguments are now supported. See the
   documentation for how this works.
