The change kind of like that, that I recall, was that using a LUT would lose the HDR, but that was fixed - all still seems ok here still with a few quick tests, I tried with tone mapping on and off, and LUTs applied and not applied, and the EXRs (saved directly from the VFB, not from the CIE, haven't tested that yet) were still responding as 16 bit half floats EXRs with the full range when an Exposure adjustment layer was used in Photoshop (loading via the EXR-IO plugin).
