Is this gem still compatible with the latest releases of Jekyll?

[fusion809]

Hi,

I have attempted to include this gem on my Jekyll site (source) by adding <time datetime="{{ page.last_modified_at | date:"%r, %A %d %B %Y" }}" itemprop="dateModified"><br/><b>Last modified</b>: {{ page.last_modified_at | date:"%I:%M %p %A, %d %B %Y" }}</time> to my _layouts/post.html file and I included the jekyll-last-modified-at gem in my _config.yml file as shown in the README of this repo and even though it is included in http://fusion809.github.io/2016/01/07/comparison-of-free-operating-systems/ as you can see the last modified field is left blank. The only way it gets a value is I assign it manually in the front matter of the post. Correct me if I am wrong but isn't this plugin meant to get the last modified date from Git?

Thanks for your time,
Brenton
