That’s strange, because I’m sure I wrote one. Perhaps I forgot to copy it over to readme.txt. I’ll remedy the issue soon, but in the meantime you can find the full changelog at GitHub.
It looks like I did update the changelog in readmetx; you can even see it in subversion. I’m guessing this is due to an error on WordPress.org; there’s nothing I can do about it, sorry.
I noticed that the link you posted was for the develop branch, does wordpress.org get the changelog from the master branch cause that branch hasen’t been updated?
Awesome to have the Fatal Error checks 🙂
The GitHub branches are completely different to the WordPress.org subversion branches. WordPress.org looks at the trunk subversion branch, or uses the tag/%current_version% branch if it exists.
GitHub is just for development work. The develop Git branch always has my latest work on the plugin, and the master branch has the latest stable version. WordPress.org doesn’t interact with GitHub at all.
Just checked this and it seems to be displaying properly now. Probably just a temporary bug with the website.
