I was using ver. 2.3.0+898~ge47c49cfc-win64 since it became available, modestly, but daily. It has never crashed.
Unlike the previous release, this one is using OpenCL - on a basic laptop without a dedicated graphic card (i3 6100U @ 2.30GHz, Intel HD Graphics 520, 8 GB DDR3, Windows 10) - pushing GPU usage up to 100 %.
On a primitive test (exporting ten 24 MP cr2 files (sharpen, 2 x profiled denoise)), it was notably slower with OpenCL deactivated.
Version 2.2.5 on Ubuntu Studio 17.04 on the same laptop (OpenCL not available) was, again, notably slower than the Windows version, but Windows system and programs are installed on a small SSD disk, while Linux is on (the slow part of) a HDD.
