+* Readelf now displays RELR relocations in full detail.
+
+* Readelf now has a -j/--display-section option which takes the name or index
+ of a section and displays its contents according to its type. The option can
+ be used multiple times on the command line to display multiple sections.
+
+* Base register 0 is now printed as "0" instead of "%r0" in s390 disassembly.
+
+* When objdump or readelf are used to display the contents of a .eh_frame
+ section they will now also display the contents of the .eh_frame_hdr section,
+ if present.
+
+* Support for the Maverick co-processor (via -mfpu=maverick) on Arm has been
+ removed. The CPU name ep9312 is still recognized, but treated as an alias
+ for arm920t.
+
+Changes in 2.42:
+
+* The objdump program has a new command line option -Z/--decompress which
+ changes the behaviour of the -s/--full-contents option, forcing it to
+ decompress the contents of any compressed section before they are displayed.
+
+ In addition when objdump is displaying sections headers (via the -h/--headers
+ command line option) it will now display "COMPRESSED" in the Flags field of
+ any compressed section.
+
+* The readelf program has a new command line option --extra-sym-info which
+ extends the information displayed by the --symbols option. When enabled
+ the display will include the name of the section referenced by a symbol's
+ index field (st_shndx). In the future more information may also be displayed
+ when this option is enabled.
+
+* objcopy --set-section-flags now supports "large" to set SHF_X86_64_LARGE
+ for ELF x86-64 objects.
+
+* objdump --visualize-jumps is now supported on s390 architecture.
+
+* The s390 disassembly now optionally includes the instruction description as
+ comment with the s390-specific disassembler option "insndesc":
+ - For objdump it can be enabled with "objdump -M insndesc ...".
+ - In gdb it can be enabled with "set disassembler-options insndesc".
+
+Changes in 2.41:
+
+* 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)
+ - Zvbb, Zvbc, Zvkg, Zvkned, Zvknh[ab], Zvksed, Zvksh, Zvkn, Zvknc, Zvkng,
+ Zvks, Zvksc, Zvkg, Zvkt (vector crypto instructions)
+
+* The RISC-V port now supports the following vendor-defined extensions:
+ - XVentanaCondOps
+
+* The LoongArch port now supports the following extensions:
+ - LSX (Loongson SIMD eXtension; 128-bit vectors)
+ - LASX (Loongson Advanced SIMD eXtension; 256-bit vectors)
+ - LVZ (Loongson Virtualization extension)
+ - LBT (Loongson Binary Translation extension)
+
+* The LoongArch disassembly output received the following tweaks:
+ - Colored output is now supported.
+ - Some pseudo-instructions are now shown in place of the canonical forms,
+ where semantics are equivalent. A disassembler option '-M no-aliases' is
+ added to disable the new behavior.
+ - Signed immediates are no longer printed with their hex representation.
+ - Unrecognized instruction words are now shown with '.word'.
+
+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.
and/or local symbols only. They now also support long options.
