+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)
other utilities should work on Risc/Ultrix and Irix.
