# Release 0.9.2 - (September 26, 2018)

* New CryptoNightSaber (BitTube) algorithm
* Improve Allium and Phi2 for 1070, 1070 Ti, 1080, 1080 Ti
* Allow to set intensity per GPU
* Fix failover mechanism
* Disable miner to auto-start after system restart
* Add crash reporting mechanism. Check Readme for more information

Not sure if others are seeing similar behavior, but the phi2 algo on 0.9.2 (all Windows CUDA builds, using 411.63 drivers) seems to bias performance on GPU0 vs. all the other GPUs on two different rigs.

On CD 9.1, I calculated a 5% delta in performance between GPU0 and GPU1 (both identical 1080ti) for phi2. On CD 9.2, this jumps to over 12%. No OC, stock PL.

After benchmarking all 6 x 1080ti in a rig, GPU0 always ends up over 1 MH/s better than all the others but only on phi2. Tests on allium, neoscrypt and lyra2z all show expected deltas in performance between GPUs.

It almost feels like an optimization was applied in code for phi2 specifically, but they forgot to apply it to any GPU past the first.
