+* The MIPS port now supports the Sony Interactive Entertainment Allegrex
+ processor, used with the PlayStation Portable, which implements the MIPS
+ II ISA along with a single-precision FPU and a few implementation-specific
+ integer instructions.
+
+* Objdump's --private option can now be used on PE format files to display the
+ fields in the file header and section headers.
+
+* New versioned release of libsframe: libsframe.so.1. This release introduces
+ versioned symbols with version node name LIBSFRAME_1.0. This release also
+ updates the ABI in an incompatible way: this includes removal of
+ sframe_get_funcdesc_with_addr API, change in the behavior of
+ sframe_fre_get_ra_offset and sframe_fre_get_fp_offset APIs.
+
+* SFrame Version 2 is now the default (and only) format version supported by
+ gas, ld, readelf and objdump.
+
+* Add command-line option, --strip-section-headers, to objcopy and strip to
+ remove ELF section header from ELF file.
+
+* The RISC-V port now supports the following new standard extensions:
+ - Zicond (conditional zero instructions)
+ - Zfa (additional floating-point instructions)
+
+* The RISC-V port now supports the following vendor-defined extensions:
+ - XVentanaCondOps
+
+Changes in 2.40:
+
+* Objdump has a new command line option --show-all-symbols which will make it
+ display all symbols that match a given address when disassembling. (Normally
+ only the first symbol that matches an address is shown).
+
+* Add --enable-colored-disassembly configure time option to enable colored
+ disassembly output by default, if the output device is a terminal. Note,
+ this configure option is disabled by default.
+
+* DCO signed contributions are now accepted.
+
+* objcopy --decompress-debug-sections now supports zstd compressed debug
+ sections. The new option --compress-debug-sections=zstd compresses debug
+ sections with zstd.
+
+* addr2line and objdump --dwarf now support zstd compressed debug sections.
+
+* The dlltool program now accepts --deterministic-libraries and
+ --non-deterministic-libraries as command line options to control whether or
+ not it generates deterministic output libraries. If neither of these options
+ are used the default is whatever was set when the binutils were configured.
+
+* readelf and objdump now have a newly added option --sframe which dumps the
+ SFrame section.
+
+Changes in 2.39:
+
+* Add --no-weak/-W option to nm to make it ignore weak symbols.
+
+* Add an option to objdump and readelf to prevent attempts to access debuginfod
+ servers when following links.
+
+* objcopy --weaken, --weaken-symbol, and --weaken-symbols now make ELF
+ STB_GNU_UNIQUE symbols weak.
+
+* objdump now supports syntax highlighting of disassembler output for some
+ architectures. Use the --disassembler-color=MODE command line flag, with
+ mode being either off, color, or extended-color.
+
+Changes in 2.38:
+
+* elfedit: Add --output-abiversion option to update ABIVERSION.
+
+* Add support for the LoongArch instruction set.
+
+* Tools which display symbols or strings (readelf, strings, nm, objdump)
+ have a new command line option which controls how unicode characters are
+ handled. By default they are treated as normal for the tool. Using
+ --unicode=locale will display them according to the current locale.
+ Using --unicode=hex will display them as hex byte values, whilst
+ --unicode=escape will display them as escape sequences. In addition
+ using --unicode=highlight will display them as unicode escape sequences
+ highlighted in red (if supported by the output device).
+
+* readelf -r dumps RELR relative relocations now.
+
+* Support for efi-app-aarch64, efi-rtdrv-aarch64 and efi-bsdrv-aarch64 has been
+ added to objcopy in order to enable UEFI development using binutils.
+
+* ar: Add --thin for creating thin archives. -T is a deprecated alias without
+ diagnostics. In many ar implementations -T has a different meaning, as
+ specified by X/Open System Interface.
+
+Changes in 2.37:
+
+* The readelf tool has a new command line option which can be used to specify
+ how the numeric values of symbols are reported. --sym-base=0|8|10|16 tells
+ readelf to display the values in base 8, base 10 or base 16. A sym base of 0
+ represents the default action of displaying values under 10000 in base 10 and
+ values above that in base 16.
+
+* Binutils now requires a C99 compiler and library to build.
+
+* A new format has been added to the nm program. Specifying
+ --format=just-symbols (or just using -j) will tell the program to only
+ display symbol names and nothing else.
+
+* A new command line --keep-section-symbols has been added to objcopy and
+ strip. This stops the removal of unused section symbols when the file is
+ copied. Removing these symbols saves space, but sometimes they are needed by
+ other tools.
+
+* objcopy --weaken, --weaken-symbol and --weaken-symbols now make undefined
+ symbols weak on targets that support weak symbols.
+
+* Readelf and objdump can now display and use the contents of .debug_sup
+ sections.
+
+* Readelf and objdump will now follow links to separate debug info files by
+ default. This behaviour can be stopped via the use of the new -wN or
+ --debug-dump=no-follow-links options for readelf and the -WN or
+ --dwarf=no-follow-links options for objdump. Also the old behaviour can be
+ restored by the use of the --enable-follow-debug-links=no configure time
+ option.
+
+ The semantics of the =follow-links option have also been slightly changed.
+ When enabled, the option allows for the loading of symbol tables and string
+ tables from the separate files which can be used to enhance the information
+ displayed when dumping other sections, but it does not automatically imply
+ that information from the separate files should be displayed.
+
+ If other debug section display options are also enabled (eg
+ --debug-dump=info) then the contents of matching sections in both the main
+ file and the separate debuginfo file *will* be displayed. This is because in
+ most cases the debug section will only be present in one of the files.
+
+ If however non-debug section display options are enabled (eg --sections) then
+ the contents of matching parts of the separate debuginfo file will *not* be
+ displayed. This is because in most cases the user probably only wanted to
+ load the symbol information from the separate debuginfo file. In order to
+ change this behaviour a new command line option --process-links can be used.
+ This will allow di0pslay options to applied to both the main file and any
+ separate debuginfo files.
+
+* Nm has a new command line option: --quiet. This suppresses "no symbols"
+ diagnostic.
+
+Changes in 2.36:
+
+* Update elfedit and readelf with LAM_U48 and LAM_U57 support.
+
+* Nm has a new command line option: --ifunc-chars=CHARS. This specifies a
+ string of one or two characters. The first character is used as the type
+ character when displaying global ifunc symbols. The second character, if
+ present is used when displaying local ifunc symbols.
+
+ In addition a new configure time option --enable-f-for-ifunc-symbols has been
+ created, which if used will change nm's default characters for ifunc symbols
+ from i (both local and global) to F (global) and f (local).
+
+* The ar tool's previously unused l modifier is now used for specifying
+ dependencies of a static library. The arguments of this option
+ (or --record-libdeps long form option) will be stored verbatim in the
+ __.LIBDEP member of the archive, which the linker may read at link time.
+
* Readelf can now display the contents of LTO symbol table sections when asked
to do so via the --lto-syms command line option.
symbol names. In addition the --demangle=<style>, --no-demangle,
--recurse-limit and --no-recurse-limit options are also now availale.
+* Add support for the SHF_GNU_RETAIN ELF section flag.
+ This flag specifies that the section should not be garbage collected by the
+ linker.
+
Changes in 2.35:
* Changed readelf's display of symbol names when wide mode is not enabled.
and/or local symbols only. They now also support long options.
