Thanks.  I've made minor changes in NEWS, but please look into fixing
this one:

  *** Indentation uses 'js-indent-level' instead of 'sgml-basic-offset'.
  It was never really intuitive that JSX indentation would be controlled
  by an SGML variable.  JSX is a syntax extension of JavaScript, so it
  should be indented just like any other expression in JavaScript.  This
  is technically a breaking change, but it will probably align with how
  you would normally expect for this indentation to be controlled, and
  you probably won't need to change your config.

Backward-incompatible changes should have a way of reverting to old
behavior.  If there is such a way already, please mention it in NEWS;
if there isn't, can we add a feature to revert to old behavior?
