Descriptive List of Customizr Version Changes

I am currently running Customizr 3.1.10 (I think!) with WordPress 3.9.1. I’ve been reluctant to install individual “point” updates of the Customizr theme for fear that it will break something within my site, which uses a Child Theme. (This happened when some of the php files changes in the “class-header” files.)

This is probably a naive question (I apologize for wasting your time!), but I cannot find a place that clearly delineates the various changes that each release of Customizr contains. Yes, I know where I can download older and newer files, but haven’t been able to find the page(s) that list the improvements or changes made from one version to the next.

Thank you!
