Quickly after the first version, we released a new version that features extended compatibility. We got many requests from customers complaining that they run Plesk 8.6 and they are not able to use 4PSA OXtender. Starting with version 1.0.1, you can use OXtender with any Plesk version higher or equal to 8.3.0. We also fixed some minor bugs and introduced new functionality, maybe the most important being that the new version can work with email passwords that are encrypted in the Plesk database (it requires IMAP auth module on the Open-Xchange server).
