A new version has been uploaded. The changes are only for the Bootstrap version and maybe some later versions of 2.3.4. If your shop is a different version, there's no need to bother with this update. Here are the changes made:
Added a clear command on the sitemap page to keep continue button in place - found by member 14steve14.
Added index modules (BS and some later 2.3.4 versions only).
Added hook for the product page (BS and some later 2.3.4 versions only).
Fixed some security issues.
Removed the install instructions that referenced database tables and filenames for the BS version - found by member valquiria23.
Please be sure to read the install file since the procedure has changed.
