With the recent release of version 1.3.0, league/commonmark now offers full support for Github-Flavored Markdown!
This weekend I've tagged the first pre-releases of the 1.x branch! I strongly encourage everyone to test their applications and extensions against this beta and provide any feedback. (Helpful information can be found in the upgrading guide.) Unless there are any major issues we'll plan on releasing a stable 1.0.0 version in the coming weeks!
This month I released updates for a few of my open-source projects including league/commonmark, league/html-to-markdown, and colinodell/json5.
