It sounds like Russia is moving its ships away from Crimean seas/ports (and shouting about how it would be a big mistake to actually launch attacks on Crimea), possibly in response to an increased influx of anti-ship capabilities by Ukraine. Running scared of several more Moskvas happening? Not that I'd blame them for being scared, but it doesn't enhance their attempt to seem 'on top of things' against the mere nuisance of Kiev's forces.
On the other side of things, Zelensky has fired two of his top people (Security Chief and Chief Prosecutor), citing the high numbers of individuals (tens of individuals, I think it was said, but clearly significant) from their respective departments who have acted for the Russians in various ways ('treasonously', which might be indeed be a correct description). Not sure of the details, but probably includes some of those who consciously took up (or continued?) puppetted positions under the enforced Russian administration, and likely a number of more active betrayals than merely allowing an occupier-friendly continuation of local-level autonomy. Again, could be necessary (I don't know how much can be ascribed to their failure to rein in the effective defections, surely no personal complicity is suspected, though). And, again, may not really look good. In this case, I hope that it's truly worth it and has been considered rather than been a knee-jerk.
