 Introduction
 ============
 
-This document contains the release notes for the lld linker, release 8.0.0.
-Here we describe the status of lld, including major improvements
-from the previous release. All lld releases may be downloaded
-from the `LLVM releases web site <https://llvm.org/releases/>`_.
+lld is a high-performance linker that supports ELF (Unix), COFF (Windows),
+Mach-O (macOS), MinGW and WebAssembly. lld is command-line-compatible with
+GNU linkers and Microsoft link.exe and is significantly faster than the
+system default linkers.
+
+nlld 8.0.0 has lots of feature improvements and bug fixes.

+* lld now attempts to place a ``.note`` segment in the first page of a
+  generated file, so that you can find some important information
+  (``.note.gnu.build-id`` in particular) in a core file even if a core
+  file is truncated by ulimit.

+* lld now reports an error if ``_GLOBAL_OFFSET_TABLE_`` symbol is

 * lld/Hexagon can now link Linux kernel and musl libc for Qualcomm

 * Initial MSP430 ISA support has landed.
 
-* The following flags have been added: ``-z interpose``, ``-z global``

 * lld now uses the ``sigrie`` instruction as a trap instruction for
   MIPS targets.
 
+* lld now creates a TLS segment for AArch64 with a slightly larger
+  alignment requirement, so that the loader makes a few bytes room
+  before each TLS segment at runtime. The aim of this change is to
+  make room to accomodate nonstandard Android TLS slots while keeping
+  the compatibility with the standard AArch64 ABI.
