+* 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
   maximum amount of recursion that is allowed whilst demangling strings.
   The value for this limit is defined by the DEMANGLE_RECRUSE_LIMIT
