The spec has been updated to 0.26:  
[http://spec.commonmark.org/0.26](http://spec.commonmark.org/0.26)

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/0.26.0)**
>
> cmark - CommonMark parsing and rendering library and program in C

  

> **[commonmark/commonmark.js](https://github.com/commonmark/commonmark.js/releases/tag/0.26.0)**
>
> commonmark.js - CommonMark parser and renderer in JavaScript

There are quite a few changes to the spec: see the [changelog](http://spec.commonmark.org/changelog.txt) for full details. Among the more important changes:

- empty list items can no longer interrupt a paragraph; this resolves an ambiguity with setext headers
- ordered lists can interrupt a paragraph only when beginning with `1`
- the two-blank-lines-breaks-out-of-lists rule has been removed
- the spec for emphasis and strong emphasis has been refined to give more intuitive results in some cases
- tabs can be used after the `#` in an ATX header and between the markers in a thematic break

cmark and commonmark.js have seen many improvements, including

- a better algorithm for parsing emphasis and links (due to Robin Stocker)
- an optional interface in cmark which permits use of a custom memory allocator for nodes (Vicent Marti)
- improvements to cmark’s renderers, especially the commonmark renderer

Thanks to all who contributed!
