* PDB GUID is set to hash of PDB contents instead to a random byte
sequence for build reproducibility.
+* ``/pdbsourcepath:`` is now also used to make ``"cwd"``, ``"exe"``, ``"pdb"``
+ in the env block of PDB outputs absolute if they are relative, and to make
+ paths to obj files referenced in PDB outputs absolute if they are relative.
+ Together with the previous item, this makes it possible to generate
+ executables and PDBs that are fully deterministic and independent of the
+ absolute path to the build directory, so that different machines building
+ the same code in different directories can produce exactly the same output.
* The following flags have been added: ``/force:multiple``
* lld now can link against import libraries produced by GNU tools.
* lld can create thunks for ARM, to allow linking images over 16 MB.
+* Several speed and memory usage improvements.
+* lld now creates debug info for typedefs.
+* lld can now link obj files produced by ``cl.exe /Z7 /Yc``.
+* lld now understands ``%_PDB%`` and ``%_EXT%`` in ``/pdbaltpath:``.
+* Undefined symbols are now printed in demangled form in addition to raw form.
