+* Added --with-lib-path configure switch to specify default value for
+  LIB_PATH.
+
+* ARM port to QNX operating system added by Graeme Peterson.
+
+* IP2K support added by Denis Chertykov.
+
+Changes in 2.13:

+* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400
+  and FR500 included.

+Changes in version 2.13:
+
+* DEC VAX ELF support, by Matt Thomas.
+
+Changes in version 2.12:
+
+* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
+
+* Support for the OpenRISC 32-bit embedded processor by OpenCores.
+
+* Support for -z nocopyreloc in the x86 ELF linker, which disables
+  production of copy relocs.  Warning: using this option may result in
+  non-sharable applications.
+
+* Support for -z combreloc in the ELF linker, which puts dynamic
+  relocations against the same symbol together, so that dynamic linker
+  can use an one-entry symbol lookup cache.
+
+* Support for ELF SHF_MERGE section merging, by Jakub Jelinek.
+
+Changes in version 2.11:
+
+* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs.
+
+* Support added for eliminating duplicate DWARF2 debug information by
+  having the compiler generate the information in sections called
+  .gnu.linkonce.wi.XXXX where XXXX is a checksum for the contents.  The
+  linker then merges these sections together into the normal .debug_info
+  section.
+
+* The native ELF linker now searches the directories in DT_RUNPATH or
+  DT_RPATH of a shared library for shared libraries needed by it.
+
+* TI C54x support, by Timothy Wall.
+
+* Added command line switch --section-start to set the start address of any
+  specified section. 
+
+* Added ability to emit full relocation information in linked executables,
+  enabled by --emit-relocs.  Some post-linkage optimization tools need
+  this information in order to be able to correctly identify and perform
+  symbol relative addressing in the event of changes in section contents
+  (instructions being added or deleted, extending data sections, etc.)
+
+* Support for i860, by Jason Eckhardt (preliminary, alpha quality).
+
+* Support for CRIS (Axis Communications ETRAX series).
+
+* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff.
+
 Changes in version 2.10:
 
+* Added AT> to the linker script language to allow load-time allocation of 
+  sections into regions.
+
 * 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.
