How much longer (or they even still) are Maxwell gpus supported by iray and Daz?

Are Maxwell gpus still supported by iray and Daz for gpu rendering? If so will they be supported up until July 13 of this year? I know Nvidia officially dropped their support for Maxwell and pascal gpus pretty recently. That's why I'm asking

They're still suppported in the lateast releases.
As for when support will be dropped, for iray, there's nothing official in any place i could find.
As for nvidia dropping support, that hasn't happend, yet.
While the release notes for CUDA 12.8, indicated that maxwell, pascal and volta, will be moved to legacy, there doesn't appear to have been any official time line released, and there's no articles on the subject i can find newer than january.
Checking the driver page, on nvidia.com, the three series haven't been moved to legacy, and are still getting some kind of updates, depending on O.S.
Until the release of DS 5 (or whatever they call the next major version), Daz won't be able to incorporate new builds of Iray into DS. That means that if Maxwell is supported in the current version, it will (theoretically) also be supported in any further versions of DS 4
RTX support was added up in the latest release of Iray, but at the same time, it also references using tensor cores.
The tensore cores in the RTX cards are newer generation than the Volta, but Volta cards (well, at least Titan V and GV100) had already tensor cores, even if the first generation, so it is not impossible they may be supported even at least a bit after Maxwell and Pascal will be dropped (and even that, as others indicated, may not come immediately), even if they do not have the specific ray tracing hardware of the RTX, considering that Iray in theory can also CPU (which have no RTX cores and no tensor cores). It may depend also on the CUDA support, as someone indicated, but the latest version of the drivers supports happily at least also the Volta (I have two, so, I know from practical experience)..
Incidentally, if by any chance you Volta is a Titan V, and you do dForce simulations, I suggest you use that for dForce simulations, the increase in speed even compared with a GV100 and with an RTX A5000 (which is newer and RTX) is huge.
Iray is updated pretty often in DS, both for new features and also for bugfixes...

The problem is that apparently Nvidia changed the C++ version used for the latest versions of Iray, so they can't be integrated in the 4.x code base. Which is why support for 50xx cards will have to wait for DS5.
Does anyone know of an ETA for this? Seems absurd to me that the software doesn't support the newest hardware months after release, or that there isn't some warning plastered over the home page that this was even a thing.
We don't know when the enxt major version will release. However, this is by no means the longest wait we have had for a new generation of cards to be supported.
