About OSMap 4
The developer is Joomlashack, previously known as Alledia.
The developer claims that OSMap 4 is "Easier to Use and 1,000% Faster" than previous versions.
OSMap 4 comes with improved more stable codebase, better admin interface and a new caching feature to support larger sites.
Backup your website before updating OSMap
ALWAYS perform a FULL back up your website before updating any extensions.
Joomla! extension updates can and do stall, and when they do they can break your website!
