I can't render ray traced translucent objects with transparency in 5.4

Hi guys.
I’ve been nicely rendering translucent object with transparency in 5.3 but after which was useful in compositing. Now I had to render an ad with the very same bottle I did months ago, but with different label and now glass doesn’t render transparent anymore. When I set IOR to 1 or make it raster then it’s ok, so I guess it’s some problem with refraction. It’s something I’d expect from the exp with rendering glass in other software, but 5.3 rendered it just fine. So maybe there’s just some setting I need to add in 5.4 now to get the same effect. I add PNG renders comparison where you can see 5.3 is nicely transparent.
