Seems to be enough of the losses inflicted by MANPADs and "Strela". Beside naturally helicopters the planes are also shot down this way. Russia doesn't really have high-precision weapons, especially battlefield level ones, (i mean they have very small number of them and have already pretty much exhausted the stores) and thus the planes forced to come closer to dump their unguided bombs - FAB-250/500, ie. 500lbs and 1000lbs, the same like in Syria - to get any result. One can enjoy this official Russian TV glorifying report (a good link seems to be taken private https://www.youtube.com/watch?v=LrekdY2FgD0 so one can go here
https://rutube.ru/video/4b400cbcfbbd6c1b730b5e80138fe598/ at the starting timestamp 24:40 and at 24:56 there is the plane's payload full frontal. These links are 2 different Russian official TV channels slightly different edits of the same propaganda scenario) on supposedly a "high-precision" strike carried out by a plane loaded only with unguided bombs (FAB-250) where they call those bombs "missiles of point-precision" and even show a video of supposed launch of a ground attack missile from that plane - a Russian propaganda miracle of an unguided bomb conversion to the missile while in flight :)
The S-300 do seems to be working as Russian planes are forced to fly all the way over Ukraine to their targets at extremely small altitude.
