I’ve released a small spec update, to 0.25.  
[http://spec.commonmark.org/](http://spec.commonmark.org/)

New versions of cmark, the C reference implementation, and commonmark.js, the JavaScript reference implementation, have also been released:

> **[commonmark/cmark](https://github.com/commonmark/cmark/releases/tag/0.25.0)**
>
> cmark - CommonMark parsing and rendering library and program in C

  

> **[commonmark/commonmark.js](https://github.com/commonmark/commonmark.js/releases/tag/0.25.0)**
>
> commonmark.js - CommonMark parser and renderer in JavaScript

Aside from some internal refactoring, the main change is better handling of tabs.

Thanks to all who contributed, especially Nick Wellnhofer, Kamil Rytarowski, and Mathieu Duponchelle for their work on cmark, and muji for work on commonmark.js.
