+* 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.

+  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"
