Well, the Ukrainian call-up age was lowered the other day (from 27 to 25, I think?), but that can of course only be in anticipation of need for manpower. (Defensive or offensive, reactive or proactive, but will always involve a boot-camp delay and everyone advising behind the scenes will of course know that this can't do anything about 'now' or the recent past any time soon.)
Also, I think this was a measure already sent through by the legislature a while ago, but Z. had held off signing until last week(?) so fully anticipated and also probably subject to various layers of go/no-go (according to the 'now' pressures in some ways).
...in short, it's not going to be any less of a meat-grinder, for either side. But I doubt there's much newsworthy change since the reported withdrawl from that noted town recently, that had apprently been soaking up so much of Russia's effort. And that seems to have been more an ammo-related decision than a manpower one.
(But, importantly, I'm only repeating/reinterpreting/passing on what has drifted my way via global news - I've not got any actual inside track on this. And, if I had, I probably be waffling away on a games forum about it, especially in the presence of those who might be directly affected, would I? Not in the face of people who are much closer to events than me and can at least claim to have more highly-ranked armchairs than me, and certainly have more skin in the game.)
edit: Meant to mention Russia's current efforts against Kharkiv. But I would imagine that any recent decisions to pull back from other places was done in order to be able to still defend/counter against threats on this part of the map, and others like it. It's doubtless a very symbolic aim, for both sides and probably no easing off by either. Several deaths from Russian drones is the latest news, but I think that meatgrinder will also be active where the ground-action currently is around that area...
