Suggestion for change log software, other than a Word/Excel sheet

Hey there, wondering if anyone has any suggestions for something that can be used for tracking changes to Windows images? I guess really any kind of a change log, other than just a Word or Excel Doc would be ideal.

Currently we’re using a page on the company’s central Sharepoint site, but that system is set to be retired, so looking for an alternative place that doesn’t rely on much infrastructure to use.

Bonus points if it can be used within Google Drive, and more importantly free.
