Bundle
Bundles are pre-configured packages, that can contain any HippoEDIT addon/extension, as: syntax files, script/binary plugins, color schemes, file templates etc.
Technically it is a zip archive (with predefined extension .hebundle) with some files and installation instruction inside (package-info.xml), which defines how/where files will be extracted and what shall be registered. In addition it contain rollback instruction to un-install the bundle. The bundle files extension is registered by HippoEDIT and installation of the bundle will be executes automatically if you open (double click) it in Windows (relevant only for > 1.50). In 1.49 “bundles” were just a zip archive with files you need to unpack by yourself. From 1.50 all updates withing Update Manager, seamlessly integrated online resources (online plugins, color schemes etc in settings) and extensions from web site are installed with help of bundles.
