+* objcopy recognizes two new options --strip-unneeded-symbol and
+  --strip-unneeded-symbols, namely for use together with the wildcard
+  matching the original --strip-symbol/--strip-symbols provided, but
+  retaining any symbols matching but needed by relocations.
+
+* readelf can now display address ranges from .debug_range sections.  This
+  happens automatically when a DW_AT_range attribute is encountered.  The
+  command line switch --debug-dump=Ranges (or -wR) can also be used to display
+  the contents of the .debug_range section.
+
+* nm and objdump now have a switch "--special-syms" to enable the displaying of
+  symbols which the target considers to be special.  By default these symbols
+  are no longer displayed.  Currently the only special symbols are the Mapping
+  symbols used by the ARM port to mark transitions between text and data and
+  between ARM and THUMB code.
+
+* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional
+  import and export symbols with <preifx> prepended to them.
+
+Changes in 2.15:
+
+* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the
+  disassembler to print the "raw" mips instruction mnemonic instead of some
+  pseudo instruction name.  I.E. print "daddu" or "or" instead of "move",
+  "sll" instead of "nop", etc.
+
+* objcopy and strip can now take wildcard patterns in symbol names specified on
+  the command line provided that the --wildcard switch is used to enable them.
+
+* readelf can now parse archives.
+
+* objdump now accepts --debugging-tags to print the debug information in a
+  format compatible with ctags tool.
+
+* objcopy and strip now accept --only-keep-debug to create a file containing
+  those sections that would be stripped out by --strip-debug.  The idea is that
+  this can be used in conjunction with the --add-gnu-debuglink switch to create
+  a two part program distribution - one a stripped executable and the other the
+  debugging info.
+
+* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink
+  section into a (presumably stripped) executable.  This allows the debug
+  information for the file to be held in a separate file.
+  
+* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX
+  single-character representation.  This can be checked by running nm
+  with the -a switch.
+
+Changes in 2.14:
+
+* Added --info switch to objcopy and strip.
+
+* Support for Vitesse IQ2000 added by Red Hat.
+
+* Added 'S' encoding to strings to allow the display of 8-bit characters.
+
+* Added --prefix-symbols=<text>, --prefix-sections=<text> and
+  --prefix-alloc-sections=<text> to objcopy.
+
+* readelf can handle the extensions to the DWARF2 spec used by the Unified
+  Parallel C compiler.
+
+* BFD no longer declares a "boolean" type, to avoid clashes with other
+  headers that declare the same.  Users of BFD should replace boolean,
+  false and true, with int, 0 and 1, or define their own boolean type.
+
 * Support for IP2K added by Denis Chertykov.
