+* Remove (rudimentary) support for the x86-64 sub-architectures Intel L1OM and
+ Intel K1OM.
+
+Changes in 2.38:
+
+* Add support for AArch64 system registers that were missing in previous
+ releases.
+
+* Add support for the LoongArch instruction set.
+
+* Add a command-line option, -muse-unaligned-vector-move, for x86 target
+ to encode aligned vector move as unaligned vector move.
+
+* Add support for Cortex-R52+ for Arm.
+
+* Add support for Cortex-A510, Cortex-A710, Cortex-X2 for AArch64.
+
+* Add support for Cortex-A710 for Arm.
+
+* Add support for Scalable Matrix Extension (SME) for AArch64.
+
+* The --multibyte-handling=[allow|warn|warn-sym-only] option tells the
+ assembler what to when it encoutners multibyte characters in the input. The
+ default is to allow them. Setting the option to "warn" will generate a
+ warning message whenever any multibyte character is encountered. Using the
+ option to "warn-sym-only" will make the assembler generate a warning whenever a
+ symbol is defined containing multibyte characters. (References to undefined
+ symbols will not generate warnings).
+
+* Outputs of .ds.x directive and .tfloat directive with hex input from
+ x86 assembler have been reduced from 12 bytes to 10 bytes to match the
+ output of .tfloat directive.
+
+* Add support for 'armv8.8-a', 'armv9-a', 'armv9.1-a', 'armv9.2-a' and
+ 'armv9.3-a' for -march in AArch64 GAS.
+
+* Add support for 'armv8.7-a', 'armv8.8-a', 'armv9-a', 'armv9.1-a',
+ 'armv9.2-a' and 'armv9.3-a' for -march in Arm GAS.
+
+* Add support for Intel AVX512_FP16 instructions.
+
+Changes in 2.37:
+
+* arm-symbianelf support removed.
+
+* Add support for Realm Management Extension (RME) for AArch64.
+
+Changes in 2.36:
+
+* Add support for Intel AVX VNNI instructions.
+
+* Add support for Intel HRESET instruction.
+
+* Add support for Intel UINTR instructions.
+
+* Support non-absolute segment values for i386 lcall and ljmp.
+
+* When setting the link order attribute of ELF sections, it is now possible to
+ use a numeric section index instead of symbol name.
+
+* Add support for Cortex-A78, Cortex-A78AE, Cortex-A78C and Cortex-X1 for
+ AArch64 and ARM.
+ Add support for Cortex-R82, Neoverse V1, and Neoverse N2 for ARM.
+
+* Add support for ETMv4 (Embedded Trace Macrocell), ETE (Embedded Trace
+ Extension), TRBE (Trace Buffer Extension)and BRBE (Branch Record Buffer
+ Extension) system registers for AArch64.
+
+* Add support for Armv8-R and Armv8.7-A AArch64.
+
+* Add support for DSB memory nXS barrier, WFET and WFIT instruction for Armv8.7
+ AArch64.
+
+* Add support for +flagm feature for -march in Armv8.4 AArch64.
+
+* Add support for +ls64 feature for -march in Armv8.7 AArch64. Add atomic
+ 64-byte load/store instructions for this feature.
+
+* Add support for +pauth (Pointer Authentication) feature for -march in
+ AArch64.
+
+* Add support for Intel TDX instructions.
+
+* Add support for Intel Key Locker instructions.
+
+* Added a .nop directive to generate a single no-op instruction in a target
+ neutral manner. This instruction does have an effect on DWARF line number
+ generation, if that is active.
+
+* Removed --reduce-memory-overheads and --hash-size as gas now
+ uses hash tables that can be expand and shrink automatically.
+
+* Add {disp16} pseudo prefix to x86 assembler.
+
+* Add support for Intel AMX instructions.
+
+* Configure with --enable-x86-used-note by default for Linux/x86.
+
+* Add support for the SHF_GNU_RETAIN flag, which can be applied to
+ sections using the 'R' flag in the .section directive.
+ SHF_GNU_RETAIN specifies that the section should not be garbage
+ collected by the linker. It requires the GNU or FreeBSD ELF OSABIs.
+
+Changes in 2.35:
+
+* X86 NaCl target support is removed.
+
+* Extend .symver directive to update visibility of the original symbol
+ and assign one original symbol to different versioned symbols.
+
+* Add support for Intel SERIALIZE and TSXLDTRK instructions.
+
+* Add -mlfence-after-load=, -mlfence-before-indirect-branch= and
+ -mlfence-before-ret= options to x86 assembler to help mitigate
+ CVE-2020-0551.
+
+* Add --gdwarf-5 option to the assembler to generate DWARF 5 debug output
+ (if such output is being generated). Added the ability to generate
+ version 5 .debug_line sections.
+
+* Add -mbig-obj support to i386 MingW targets.
+
+Changes in 2.34:
+
+* Add -malign-branch-boundary=NUM, -malign-branch=TYPE[+TYPE...],
+ -malign-branch-prefix-size=NUM and -mbranches-within-32B-boundaries
+ options to x86 assembler to align branches within a fixed boundary
+ with segment prefixes or NOPs.
+
+* Add support for Zilog eZ80 and Zilog Z180 CPUs.
+
+* Add support for z80-elf target.
+
+* Add support for relocation of each byte or word of multibyte value to Z80
+ targets (just use right shift to 0, 8, 16, or 24 bits or AND operation
+ with 0xff/0xffff mask): ld a, label >> 16 \ ld hl, label & 0xffff
+
+* Add SDCC support for Z80 targets.
+
+Changes in 2.33:
+
+* Add support for the Arm Scalable Vector Extension version 2 (SVE2)
+ instructions.
+
+* Add support for the Arm Transactional Memory Extension (TME)
+ instructions.
