We have just released v5.5 resolving major problem with message delete and German translation file for messages. We have also improved OssnBlock bit of it.
I am sorry for early release as i can not keep you apart from the major issue fix and to make your website open to issues. Our general release time-frame is 6 to 7 months but these issues made us to release v5.4 and 5.5 before that time frame.
Next release would be OSSN 6.0 which can be expect after 6 to 7 months. Unless no major critical issue found 😂😂
