-Changes since version 2.5:
+Changes in version 2.10:
+
+* Added garbage collection of unused sections, enabled by --gc-sections. 
+  It does require a bit of backend support; currently implemented are
+  ppc-elf, mips-elf, and mn10300-elf.  Others will ignore the option.
+
+* Added SORT to the linker script language to permit sorting sections by file
+  name or section name.
+
+* Added EXTERN to the linker script language as an equivalent to the -u
+  command-line option.
+
+* Added ASSERT to the linker script language.
+
+* Added EXCLUDE_FILE to the linker script language for further control over
+  wildcard file names.
+
+* Added -O option to optimize linker output (as of this writing, this only
+affects ELF shared library generation).
+
+* The -e option now accepts a number as well as a symbol name.
+
+* Added --no-undefined option to disallow undefined symbols when creating a
+  shared library.
+
+* Added --demangle and --no-demangle options.
+
+Changes in version 2.9:
+
+* Added SQUAD to the linker script language.
+
+* New option --no-warn-mismatch.
+
+* The MEMORY command now parses the attributes to determine where sections that
+  are not placed in a specific memory region are placed.
+
+Changes in version 2.8:
+
+* Linker scripts may now contain shell wildcard characters for file and section
+  names.
+
+* The linker now supports symbol versions in ELF.
+
+* The NOCROSSREFS command was added to the linker script language.
+
+* The LOADADDR expression was added to the linker script language.
+
+* MAX and MIN functions were added to the linker script language.
+
+* The OVERLAY construct was added to the linker script language.
+
+* New option --warn-section-align to warn when the address of an output section
+  changes due to alignment of an input section.
+
+* New options --filter/-F and --auxiliary/-f.
+
+Changes in version 2.7:
+
+* New option --cref to print out a cross reference table.
+
+* New option --wrap SYMBOL.
+
+* New option --no-whole-archive, to turn off the effect of --whole-archive.
+
+* Input sections assigned to the output section /DISCARD/ in the linker script
+  are not included in the output file.
+
+* The SunOS and ELF linkers now merge stabs debugging information which uses
+  the N_BINCL and N_EINCL stab types.  This reduces the amount of debugging
+  information generated.

+* The linker now supports linking PIC compiled code on SPARC SunOS.  It can
+also create SPARC SunOS shared libraries, and, like the native SunOS linker,
+will do so whenever there is an undefined symbol in the link and neither the -e

+
+* The -rpath option may be used on SunOS to set the list of directories to be
+searched at run time.  This overrides the default of building the list from the
+-L options.
 
 * The COFF linker now combines debugging information for structs, unions, and
 enums, so that even if the same type is defined in multiple input files it will
 only be defined once in the output file.  The --traditional-format switch will
 prevent this optimization.
