I made some improvements on the Plone addon that is used for the templates part of the website https://extensions.libreoffice.org. This improvements made it possible to remove older versions of LibreOffice from the compatibility list. The template will show their compatibility with older versions furthermore, if the contributor choose that compatibility in the past. With the new Plone addon release the site will get the compatibility information of a template from the index of the Plone portal_catalog. The new release is available at the ‘CheeseShop’: https://pypi.org/project/tdf.templateuploadcenter/
