Currently there seem to be developments in two areas.
More solid are reports about a Ukrainian assault on the Svatove/Kreminna front line (continuation of the Izyum/Lyman operations). It looks like that front might collapse soon (rather days than weeks), Russian telegram channels already reached the "Don't panic" stage in their reporting about that area.
Much more doubtful are reports from the Kherson area.
It seems reasonable to assume that Ukraine took Kinburn peninsula by an amphibious assault (the left green circle), which is a difficult area for heavy equipment. But there are some reports that they moved quite a long way to the east and took villages there (the smaller green circles). If that should be true (which I doubt) it would mean that they already took a huge part of the left bank of the river, just days after the huge Russian retreat happened exactly there. Where are the Russians? Why should a small amphibious assault unit be able to perform such a large operation? At the moment I believe this to be just rumours and wishful thinking.
