- **NEW**: Arithmatex now *just* uses the script wrapper output as it is the most reliable output, and now previews can be achieved by providing a span with class `MathJax_Preview` that gets auto hidden when the math is rendered. `insert_as_script`, `tex_inline_wrap`, and `tex_block_wrap` have all been deprecated as they are now entirely unnecessary. A new option has been added called `preview` that controls whether the script output generates a preview or not when the rendered math output is loading. Users no longer need to configure `tex2jax.js` in there MathJax configuration anymore. (171)
- **NEW**: PlainHTML has been renamed to StripHTML. `strip_attributes` is now a list instead of a string with a default of `[]`. `pymdownx.plainhtml` is still available with the old convention for backwards compatibility, but will be removed for version 5.0. (176)
- **FIX**: PlainHTML has better script and style content avoidance to keep from stripping HTML tags and attributes from style and script content. (174)
- **FIX**: PlainHTML can strip attributes that are not quoted. (174)
