| Non-comprehensive list of changes in this release |
| ================================================= |

| ELF Improvements |
| ---------------- |
| |
| * New ``--time-trace`` option records a time trace file that can be viewed in |
| chrome://tracing. The file can be specified with ``--time-trace-file``. |
| Trace granularity can be specified with ``--time-trace-granularity``. |
| (`D71060 <https://reviews.llvm.org/D71060>`_) |
| * For ARM architectures the default max page size was increased to 64k. |
| This increases compatibility with systems where a non standard page |
| size was configured. This also is inline with GNU ld defaults. |
