Tested working with xF2.1
Incompatibility with UI.X theme
Maximum icon size not taken into account. Size now fixed to default xF style 46px and option removed.
Missing js files
Double icons displayed in admincp nodes list (custom one and xF default one)
Icons with size higher than 46px gets truncated.
A new option was added to fix the second issue.
Final release - Core released as a separate add-on
Incorrect uninstall database columns dropping code
Server/Sprite icons not showing for nodes with permissions (private or restricted)
Update of [XFA] Core to Beta 3 version
