 * Added support for ``--time-trace`` and associated ``--time-trace-granularity``.
   This generates a .json profile trace of the linker execution.
+  (`#68236 <https://github.com/llvm/llvm-project/pull/68236>`_)
+
+* The ``-dependentloadflag`` option was implemented.
+  (`#71537 <https://github.com/llvm/llvm-project/pull/71537>`_)
 
 * LLD now prefers library paths specified with ``-libpath:`` over the implicitly
   detected toolchain paths.
+  (`#78039 <https://github.com/llvm/llvm-project/pull/78039>`_)
+
+* Added new options ``-lldemit:llvm`` and ``-lldemit:asm`` for getting
+  the output of LTO compilation as LLVM bitcode or assembly.
+  (`#66964 <https://github.com/llvm/llvm-project/pull/66964>`_)
+  (`#67079 <https://github.com/llvm/llvm-project/pull/67079>`_)
+
+* Added a new option ``-build-id`` for generating a ``.buildid`` section
+  when not generating a PDB. A new symbol ``__buildid`` is generated by
+  the linker, allowing code to reference the build ID of the binary.
+  (`#71433 <https://github.com/llvm/llvm-project/pull/71433>`_)
+  (`#74652 <https://github.com/llvm/llvm-project/pull/74652>`_)
+
+* A new, LLD specific option, ``-lld-allow-duplicate-weak``, was added
+  for allowing duplicate weak symbols.
+  (`#68077 <https://github.com/llvm/llvm-project/pull/68077>`_)
+
+* More correctly handle LTO of files that define ``__imp_`` prefixed dllimport
+  redirections.
+  (`#70777 <https://github.com/llvm/llvm-project/pull/70777>`_)
+  (`#71376 <https://github.com/llvm/llvm-project/pull/71376>`_)
+  (`#72989 <https://github.com/llvm/llvm-project/pull/72989>`_)
+
+* Linking undefined references to weak symbols with LTO now works.
+  (`#70430 <https://github.com/llvm/llvm-project/pull/70430>`_)
 
 * Use the ``SOURCE_DATE_EPOCH`` environment variable for the PE header and
   debug directory timestamps, if neither the ``/Brepro`` nor ``/timestamp:``
   options have been specified. This makes the linker output reproducible by
   setting this environment variable.
+  (`#81326 <https://github.com/llvm/llvm-project/pull/81326>`_)
+
+* Lots of incremental work towards supporting linking ARM64EC binaries.
 
 MinGW Improvements
 ------------------
 
 * Added support for many LTO and ThinLTO options (most LTO options supported
   by the ELF driver, that are implemented by the COFF backend as well,
   should be supported now).
+  (`D158412 <https://reviews.llvm.org/D158412>`_)
+  (`D158887 <https://reviews.llvm.org/D158887>`_)
+  (`#77387 <https://github.com/llvm/llvm-project/pull/77387>`_)
+  (`#81475 <https://github.com/llvm/llvm-project/pull/81475>`_)
 
 * LLD no longer tries to autodetect and use library paths from MSVC/WinSDK
   installations when run in MinGW mode; that mode of operation shouldn't
   ever be needed in MinGW mode, and could be a source of unexpected
   behaviours.
+  (`D144084 <https://reviews.llvm.org/D144084>`_)
 
 * The ``--icf=safe`` option now works as expected; it was previously a no-op.
-
-* More correctly handle LTO of files that define ``__imp_`` prefixed dllimport
-  redirections.
+  (`#70037 <https://github.com/llvm/llvm-project/pull/70037>`_)
 
 * The strip flags ``-S`` and ``-s`` now can be used to strip out DWARF debug
   info and symbol tables while emitting a PDB debug info file.
+  (`#75181 <https://github.com/llvm/llvm-project/pull/75181>`_)
+
+* The option ``--dll`` is handled as an alias for the ``--shared`` option.
+  (`#68575 <https://github.com/llvm/llvm-project/pull/68575>`_)
+
+* The option ``--sort-common`` is ignored now.
+  (`#66336 <https://github.com/llvm/llvm-project/pull/66336>`_)
