+* ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
+  .extCoreRegister pseudo-ops that allow an user to define custom
+  instructions, conditional codes, auxiliary and core registers.
 
-* Add a configure option --enable-compressed-debug-sections=[yes|no] to decide
-  whether DWARF debug sections should be compressed by default.
+* Add a configure option --enable-elf-stt-common to decide whether ELF
+  assembler should generate common symbols with the STT_COMMON type by
+  default.  Default to no.
 
-* Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
-  assembler support for Argonaut RISC architectures.
+* New command line option --elf-stt-common= for ELF targets to control
+  whether to generate common symbols with the STT_COMMON type.
+
+* Add ability to set section flags and types via numeric values for ELF
+  based targets.
+
+* Add a configure option --enable-x86-relax-relocations to decide whether
+  x86 assembler should generate relax relocations by default.  Default to
+  yes, except for x86 Solaris targets older than Solaris 12.
+
+* New command line option -mrelax-relocations= for x86 target to control
+  whether to generate relax relocations.
+
+* New command line option -mfence-as-lock-add=yes for x86 target to encode
+  lfence, mfence and sfence as "lock addl $0x0, (%[re]sp)".
+
+* Add assembly-time relaxation option for ARC cpus.
 
 Changes in 2.26:
 
+* Add a configure option --enable-compressed-debug-sections={all,gas} to
+  decide whether DWARF debug sections should be compressed by default.
+
+* Add support for the ARC EM/HS, and ARC600/700 architectures.  Remove
+  assembler support for Argonaut RISC architectures.
+
 * Symbol and label names can now be enclosed in double quotes (") which allows
   them to contain characters that are not part of valid symbol names in high
   level languages.
