+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
and/or local symbols only. They now also support long options.
