+* Speed up direct linking with DLLs for Cygwin and Mingw targets.
+
+* Add a configure option --enable-separate-code to decide whether
+ -z separate-code should be enabled in ELF linker by default. Default
+ to yes for Linux/x86 targets. Note that -z separate-code can increase
+ disk and memory size.
+
+Changes in 2.30:
+
+* Add -z separate-code to generate separate code PT_LOAD segment.
+
+* Add "-z undefs" command line option as the inverse of the "-z defs" option.
+
+* Add -z globalaudit command line option to force audit libraries to be run
+ for every dynamic object loaded by an executable - provided that the loader
+ supports this functionality.
+
+* Tighten linker script grammar around file name specifiers to prevent the use
+ of SORT_BY_ALIGNMENT and SORT_BY_INIT_PRIORITY on filenames. These would
+ previously be accepted but had no effect.
+
+* The EXCLUDE_FILE directive can now be placed within any SORT_* directive
+ within input section lists.
+
+Changes in 2.29:
+
+* Support for -z shstk in the x86 ELF linker to generate
+ GNU_PROPERTY_X86_FEATURE_1_SHSTK in ELF GNU program properties.
+
+* Add support for GNU_PROPERTY_X86_FEATURE_1_SHSTK in ELF GNU program
+ properties in the x86 ELF linker.
+
+* Add support for GNU_PROPERTY_X86_FEATURE_1_IBT in ELF GNU program
+ properties in the x86 ELF linker.
+
+* Support for -z ibtplt in the x86 ELF linker to generate IBT-enabled
+ PLT.
+
+* Support for -z ibt in the x86 ELF linker to generate IBT-enabled
+ PLT as well as GNU_PROPERTY_X86_FEATURE_1_IBT in ELF GNU program
+ properties.
+
+* Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
+
+* Add support for ELF GNU program properties.
+
+* Add support for the Texas Instruments PRU processor.
+
+* When configuring for arc*-*-linux* targets the default linker emulation will
+ change if --with-cpu=nps400 is used at configure time.
+
+* Improve assignment of LMAs to orphan sections in some edge cases where a
+ mixture of both AT>LMA_REGION and AT(LMA) are used.
+
+* Orphan sections placed after an empty section that has an AT(LMA) will now
+ take an load memory address starting from LMA.
+
+* Section groups can now be resolved (the group deleted and the group members
+ placed like normal sections) at partial link time either using the new linker
+ option --force-group-allocation or by placing FORCE_GROUP_ALLOCATION into the
+ linker script.
+
+Changes in 2.28:
+
+* The EXCLUDE_FILE linker script construct can now be applied outside of the
+ section list in order for the exclusions to apply over all input sections in
+ the list.
+
+* Add support for the RISC-V architecture.
+
+* The command line option --no-eh-frame-hdr can now be used in ELF based
+ linkers to disable the automatic generation of .eh_frame_hdr sections.
+
+* Add --in-implib=<infile> to the ARM linker to enable specifying a set of
+ Secure Gateway veneers that must exist in the output import library specified
+ by --out-implib=<outfile> and the address they must have. As such,
+ --in-implib is only supported in combination with --cmse-implib.
+
+* Extended the --out-implib=<file> option, previously restricted to x86 PE
+ targets, to any ELF based target. This allows the generation of an import
+ library for an ELF executable, which can then be used by another application
+ to link against the executable.
+
+Changes in 2.27:
+
+* Add a configure option --enable-relro to decide whether -z relro should
+ be enabled in ELF linker by default. Default to yes for all Linux
+ targets except FRV, HPPA, IA64 and MIPS. Note that -z relro can increase
+ disk and memory size.
+
+* Support for -z noreloc-overflow in the x86-64 ELF linker to disable
+ relocation overflow check.
+
+* Add -z common/-z nocommon options for ELF targets to control whether to
+ convert common symbols to the STT_COMMON type during a relocatable link.
+
+* Support for -z nodynamic-undefined-weak in the x86 ELF linker, which
+ avoids dynamic relocations against undefined weak symbols in executable.
+
+* The NOCROSSREFSTO command was added to the linker script language.
+
+* Add --no-apply-dynamic-relocs to the AArch64 linker to do not apply link-time
+ values for dynamic relocations.
+
+Changes in 2.26:
+
+* Add --fix-stm32l4xx-629360 to the ARM linker to enable a link-time
+ workaround for a bug in the bus matrix / memory controller for some of
+ the STM32 Cortex-M4 based products (STM32L4xx)
+
+* Add a configure option --enable-compressed-debug-sections={all,ld} to
+ decide whether DWARF debug sections should be compressed by default.
+
+* Add support for the ARC EM/HS, and ARC600/700 architectures.
+
+* Experimental support for linker garbage collection (--gc-sections)
+ has been enabled for COFF and PE based targets.
+
+* New command line option for ELF targets to compress DWARF debug
+ sections, --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi].
+
+* New command line option, --orphan-handling=[place|warn|error|discard], to
+ adjust how orphan sections are handled. The default is 'place' which gives
+ the current behaviour, 'warn' and 'error' issue a warning or error
+ respectively when orphan sections are found, and 'discard' will discard all
+ orphan sections.
+
+* Add support for LLVM plugin.
+
+* Add --print-memory-usage option to report memory blocks usage.
+
+* Add --require-defined option, it's like --undefined except the new symbol
+ must be defined by the end of the link.
+
+Changes in 2.25:
+
+* PE binaries now once again contain real timestamps by default. To disable
+ the inclusion of a timestamp in a PE binary, use the --no-insert-timestamp
+ command line option.
+
+* Replace support for openrisc and or32 with support for or1k.
+
+* Add support for the --build-id command line option to COFF based targets.
+
+* x86/x86_64 pe-coff now supports the --build-id option.
+
+* Add support for the Andes NDS32.
+
+Changes in 2.24:
+
+* Add LOG2CEIL() builtin function to the linker script language
+
+* Add support for the Texas Instruments MSP430X processor.
+
+* Add support for Altera Nios II.
+
+* Add support for the V850E3V5 architecture.
+
+* Add support for the Imagination Technologies Meta processor.
+
+* --enable-new-dtags no longer generates old dtags in addition to new dtags.
+
+* Remove linker support for MIPS ECOFF targets.
+
+* Add ALIGN_WITH_INPUT to the linker script language to force the alignment of
+ an output section to use the maximum alignment of all its input sections.
+
Changes in 2.23:
* Enable compressed debug section feature for x86/x86_64 pe-coff.
other utilities should work on Risc/Ultrix and Irix.
