+Changes in 2.20:
+
+* GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
+  pseudo op.  It marks the symbol as being globally unique in the entire
+  process.
+
+* ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
+  in binary rather than text.
+
+* Add support for common symbol alignment to PE formats.
+
+* 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.
+
+* Add support for Xilinx MicroBlaze 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.
