The inline plugin update system was updated for Store Locator Plus today. The new updates, which ship as part of the WordPress Development Kit plugin, resolve several issues that prevented some combinations of premium add-on packs from completing the update request processing. The update fixes a problem where some add-on packs would not display the details of the change log for premium add-on packs. The update also addresses and issue where some add-on packs would not complete the download and installation or would loop through a cycle of installing the currently installed version.
For users of the WordPress Development Kit plugin, the patches resolve issues where the readme.txt files for premium add-on packs are moved, deleted, or marked as unreadable by the readme processing system built into the plugin. Users of the WordPress Development Kit should update their installation to resolve their plugin distribution and update system.
