This beta release of WebGUI 7.10.19 contains fixes for the Calendar, Thingy
and the Site starter.

The Underground User style template has been removed.  If your site was using
it as a User Function style, it was replaced by the Underground Style template.
The navigation in that template was changed to prevent the rendering problems
that necessitated the Underground User style.

Changelog:
 - fixed #12169: extras uploads symlink export
 - Added ability to pass caller assetId to RenderThingMacro
 - Allow specific expirations for groups in userImport.pl
 - fixed #12164: Calendar feeds with tons of ;adminId=XXXXXX added
 - fixed #12167: Calendar Next/Prev Month/Year confusion
 - fixed #12172: Underground User Style template shows up in Style wizard during site creation
 - fixed #12157: www_editThingSave
