+* Binutils now supports debuginfod, an HTTP server for distributing
+ ELF/DWARF debugging information as well as source code. When built with
+ debuginfod, readelf and objdump can automatically query debuginfod
+ servers for separate debug files when they otherwise cannot be found.
+ To build binutils with debuginfod, pass --with-debuginfod to configure.
+ This requires libdebuginfod, the debuginfod client library. debuginfod
+ is distributed with elfutils, starting with version 0.178. For more
+ information see https://sourceware.org/elfutils.
+
+* Add --output option to the "ar" program. This option can be used to specify
+ the output directory when extracting members from an archive.
+
+* Add --keep-section option to objcopy and strip. This option keeps the
+ specified section from being removed.
+
+Changes in 2.33:
+
+* Add --source-comment[=<txt>] option to objdump which if present,
+ provides a prefix to source code lines displayed in a disassembly.
+
+* Add --set-section-alignment <section-name>=<align> option to objcopy to allow
+ the changing of section alignments.
+
+* Add --verilog-data-width option to objcopy for verilog targets to control
+ width of data elements in verilog hex format.
+
+* Add support for the Armv8.1-M Mainline and M-profile Vector Extension (MVE)
+ instructions.
+
+* The separate debug info file options of readelf (--debug-dump=links
+ and --debug-dump=follow) and objdump (--dwarf=links and
+ --dwarf=follow-links) will now display and/or follow multiple links if
+ more than one are present in a file. (This usually happens when gcc's
+ -gsplit-dwarf option is used).
+
+ In addition objdump's --dwarf=follow-links now also affects its other
+ display options, so that for example, when combined with --syms it will
+ cause the symbol tables in any linked debug info files to also be
+ displayed. In addition when combined with --disassemble the --dwarf=
+ follow-links option will ensure that any symbol tables in the linked
+ files are read and used when disassembling code in the main file.
+
+ * Add support for dumping types encoded in the Compact Type Format
+ to objdump and readelf.
+
Changes in 2.32:
* The addr2line, c++filt, nm and objdump tools now have a limit on the
3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
compatibility.
+* The size tool now has a new output format '--format=GNU' or '-G'. The
+ results are displayed in a similar manor to the default berkeley layout,
+ except read-only data is counted in the data column, not the text column.
+ Additionally the total is only included once.
+
Changes in 2.31:
* Add support for disassembling netronome Flow Processor (NFP) firmware files.
and/or local symbols only. They now also support long options.
