Since we have been growing more and more popular, we have launched 6 more realms for the most popular languages in IO.
Here is the list for which languages they are for:
R26 - Polish (that would be Polish realm 3)
R27 - Romanian (that would be Romanian realm 3)
R28 - Spanish (that would be Spanish realm 3)
R29 - Turkish (that would be Turkish realm 3)
R30 - Portuguese (that would be Portuguese realm 3)
R31 - International (English)
All of these realms are running version 4.
