+* 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.
+
+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.
+
+* 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].
-* Add --warn-orphan option to report orphan sections.
+* 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
other utilities should work on Risc/Ultrix and Irix.
