Currently Openfire is not able to recognize plugin's version which has 3 dots (e.g. 188.8.131.52). So it presents it as 0.0.0 in the list of available plugins and once installed. Because of that it doesn't show that there is a newer version of inVerse plugin available, which uses 3 dots instead of 2 dots as other plugins. This worked fine while inVerse was using x.x.x-Release-1 scheme. I guess dashes have no effect there.
