| Introduction |
| ============ |
| |
| This document contains the release notes for the lld linker, release |release|. |

| from the previous release. All lld releases may be downloaded |
| from the `LLVM releases web site <https://llvm.org/releases/>`_. |
| |
| Non-comprehensive list of changes in this release |
| ================================================= |
| |
| ELF Improvements |
| ---------------- |
| |
| * ``--fat-lto-objects`` option is added to support LLVM FatLTO. |
| Without ``--fat-lto-objects``, LLD will link LLVM FatLTO objects using the |
| relocatable object file. (`D146778 <https://reviews.llvm.org/D146778>`_) |
| * common-page-size can now be larger than the system page-size. |
| (`#57618 <https://github.com/llvm/llvm-project/issues/57618>`_) |
| |
| Breaking changes |
| ---------------- |
| |
| COFF Improvements |
| ----------------- |
| |
| * Added support for ``--time-trace`` and associated ``--time-trace-granularity``. |
| This generates a .json profile trace of the linker execution. |
| |
| MinGW Improvements |
| ------------------ |
| |
| MachO Improvements |
| ------------------ |
| |
| WebAssembly Improvements |
| ------------------------ |
| |
| * Indexes are no longer required on archive files. Instead symbol information |
| is read from object files within the archive. This matches the behaviour of |
| the ELF linker. |
