Fixed: Mi Sphere camera: automatic levelling worked only for JPEG images, not for DNG images.Now PTGui will show a more helpful error message. If an unsuitable color profile was selected for the output (for example a source-only profile), PTGui would show a cryptic error message ('cmsCreateTransformTHR failed').Fixed: cropping circle of the lens profile for the Samsung Gear 360 (2016 model) was slighly too large.Fixed: subtle color banding artifacts could appear in the output if multiband blending was used and GPU acceleration enabled.Fixed: if 'Optimize Brightness' was enabled in the automatic exposure and color adjustment settings (in the Exposure/HDR tab), the brightness optimization could behave erratic, resulting in very dark images.Fixed: PTGui when launched with the -stitchnogui flag could (incorrectly) show a popup 'It appears that PTGui previously crashed while using OpenCL for GPU acceleration.'.

Fixed: PTGui when launched with the -stitchnogui flag could display an error message 'invalid lock file'.PTGui would fail to load certain DNG files, giving the error message 'Unknown error'.Fixed: certain larger panoramas could have rendering artifacts (dark blobs or random colors).Added support for DNG files with embedded JpegXL encoded data, as created by recent versions of Adobe LightRoom and Photoshop.
