ReSpec: highlighter and news

Hi ReSpec users,
We are super excited to announce an update to ReSpec's syntax highlighter - coming in the next day or so. We are ditching the old google prettify and moving to "hljs" [1]. This is exciting because it brings support for ES2016 syntax,  performance improvements, smart language detection, and ongoing updates. 

How does this impact you? 

* pre elements will be highlighted by default (yay!). You can opt out totally by setting "noHighlightCSS: true," in your ReSpec config - or give an individual pre a "nohighlight" class.

* having a "highlight" class is now deprecated (it will generate a warning).

Other cool things we are releasing: 

 * we've upgraded our markdown support: you can now use ``` to denote a code block, just like on GitHub.

* beatification of output. When you export (X)HTML for publication, ReSpec will try to beautify the generated code a bit for you (section tags will be nested, etc.).  

We hope ❤️ like the updates! Any issues, please let us know.
