ELF Improvements
----------------

* Glob pattern, which you can use in linker scripts or version scripts,
  now supports `\` and `[!...]`. Except character classes
  (e.g. `[[:digit:]]`), lld's glob pattern should be fully compatible
  with GNU now. (`r375051

WebAssembly Improvements
------------------------

* `__data_end` and `__heap_base` are no longer exported by default,
  as it's best to keep them internal when possible. They can be
  explicitly exported with `--export=__data_end` and
  `--export=__heap_base`, respectively.
