+* Add support for loaction views in DWARF debug line information.
+
+Changes in 2.29:
+
+* Add support for ELF SHF_GNU_MBIND.
+
+* Add support for the WebAssembly file format and wasm32 ELF conversion.
+
+* PowerPC gas now checks that the correct register class is used in
+ instructions. For instance, "addi %f4,%cr3,%r31" warns three times
+ that the registers are invalid.
+
+* Add support for the Texas Instruments PRU processor.
+
+* Support for the ARMv8-R architecture and Cortex-R52 processor has been
+ added to the ARM port.
+
+Changes in 2.28:
+
+* Add support for the RISC-V architecture.
+
+* Add support for the ARM Cortex-M23 and Cortex-M33 processors.
+
+Changes in 2.27:
+
+* Default to --enable-compressed-debug-sections=gas for Linux/x86 targets.
+
+* Add --no-pad-sections to stop the assembler from padding the end of output
+ sections up to their alignment boundary.
+
+* Support for the ARMv8-M architecture has been added to the ARM port. Support
+ for the ARMv8-M Security and DSP Extensions has also been added to the ARM
+ port.
+
+* 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-elf-stt-common to decide whether ELF
+ assembler should generate common symbols with the STT_COMMON type by
+ default. Default to no.
+
+* 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.
+
+* Add --with-cpu=TYPE configure option for ARC gas. This allows the default
+ cpu type to be adjusted at configure time.
+
+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.
+
+* Added the correctly spelled -march=armv6kz, for ARMv6KZ support. The
+ previous spelling, -march=armv6zk, is still accepted.
+
+* Support for the ARMv8.1 architecture has been added to the Aarch64 port.
+ Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
+ extensions has also been added to the Aarch64 port.
+
+* Support for the ARMv8.1 architecture has been added to the ARM port. Support
+ for the individual ARMv8.1 Adv.SIMD and PAN architecture extensions has also
+ been added to the ARM port.
+
+* Extend --compress-debug-sections option to support
+ --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
+ targets.
+
+* --compress-debug-sections is turned on for Linux/x86 by default.
+
+Changes in 2.25:
+
+* Add support for the AVR Tiny microcontrollers.
+
+* Replace support for openrisc and or32 with support for or1k.
+
+* Enhanced the ARM port to accept the assembler output from the CodeComposer
+ Studio tool. Support is enabled via the new command line option -mccs.
+
* Add support for the Andes NDS32.
Changes in 2.24:
of new CPUs and formats, lots of bugs fixed.
