An Upgrade Package in Joomla! is an archive of files that contain the files that have changed between Joomla! versions. When this archive is unpacked, it replaces the old version of the modified files with the new version. For example, if fifty files were changed between version 3.x.1 and 3.x.2, the upgrade package from 3.x.1 to 3.x.2 would contain these fifty files and, when unpacked, would replace these fifty files and upgrade the installed version from 3.x.1 to 3.x.2.

Template style is a feature introduced in Joomla 2.5 that allows users to assign different template styles to individual menu items. By default, Joomla! assigns a template style to all menu items upon installation. A yellow star indicates the default template style in use. A default template style can be partially or completely overridden by assigning different template styles to the desired menu items in order to obtain a different look for their respective pages.
