At any given point of time we will support and maintain our plugins for three most recent versions of nopCommerce releases. So for example, if nopCommerce version 3.30 is the most recent release, then we will keep maintaining and supporting our plugins for nopCommerce version 3.30, 3.20 and 3.10. We’ll drop support for the older version from our plugin when new version of nopCommerce is released.
This does not mean that nopAccelerate plugins will not work with older versions of nopCommerce. It will work. But we’ll not upgrade the older version of plugin to have newer features or bug fixes. All the new development, bug fixing and enhancements are going to be supported on the three recent nopCommerce releases only.
