I have the lastest version of Xstore up to now (3.16.2) and this post is almost a month ago but I also see the same message “Your theme (XStore) contains outdated copies of some WooCommerce template files”
How and when will you release the version to solved this?
These are the files I see:
xstore/woocommerce/single-product/product-image.php version 3.0.2 is out of date. The core version is 3.1.0,
xstore/woocommerce/single-product/product-thumbnails.php version 3.0.2 is out of date. The core version is 3.1.0,
