Changelog for 3.18

Hello,

I'm curious if there is a changelog for the Steakhouse template for Joomla 3? I currently have a heavily modified (mostly CSS) version of 3.15 and was wondering if the changes were worth the trouble. Especially since I am having issues with the inset and sidebars.

Thank you,
john
