Version 1.67.1
--------------

- The debugger now has a "backtrace full" command which works very similarly to
  its GDB equivalent.

- The GObject.ParamFlags.CONSTRUCT_ONLY flag is now correctly enforced, when
  using it on GObject classes defined in JavaScript. This might break code that
  was incorrectly trying to set a property that it had previously defined as
  construct-only. The workaround is to remove the CONSTRUCT_ONLY flag.

- Fixed exception when calling GObject.Type().

- Several performance improvements.

- Progress on ES Modules.
