Software Update: Darktable 4.0.1

Version 4.0.1 of Darktable has been released. Darktable is an open source raw photo editing program, a virtual light box and dark room for photo editing. It manages digital negatives through a database. The raw photo files are developed by means of so-called sidecar files, whereby the photos are processed in a non-destructive manner. The software is available for various Linux distributions, macOS and Windows. The following changes and improvements have been made in this release:

changes

• Variables $(MAKER) and $(MODEL) can now be used when importing files.
• Display infinity for very large focus distance as supported by the exif standard.

Bug fixes

• Fix overexposed indicators after cropping.
• Fix DNG ​​creation in the HDR merge module (ColorMatrix could be zero).
• Fix culling layout, which could be broken after a second use when changing the number of images (eg when rejecting an image).
• Fix GUI reset of the export module when using TIFF format.
• Fix copy of iop-order in merge mode when multiple instances are used in the destination images.
• Fix color filter issue on Windows.
• Fix possible black screen when using auto-white balance on Windows.
• Properly retain the access and modified timestamps when using copy and import.
• Fix color picker reset in color zones module.
• Fix help link for module layout management.
• Fix crash after a failed camera tethering attempt.
• Add support for fast pipe mode on the diffuse module. Fast pipe mode is used to bypass long-running modules while interactively changing another module’s parameters where that module does not require accurate image display. For example, it is used to improve responsiveness of the on-screen display in the crop and rotate/perspective modules.
• Fix some color picker button action types.
• Fix crash in Latex export.
• Fix website gallery export.
• Fix a file handle leak.
• Fix a memory corruption in sharpen module that could lead to a crash.
• Fix vectorscope histogram display to avoid cropping the primary and secondary nodes (top and bottom).
• Add HEIF media type association for the desktop.
• Fix possible crash when using the color checker without a properly selected patch.
• Fix sorting of LUT 3D files and left-align the entries for better readability.
• Disable upscaling when export size is set to original image dimensions (0) as this does not have meaning and could crash darktable.
• Fix possible crash when applying a time-offset to images.
• Fix crop-size information displayed on screen (rounding issue).
• Fix blending detail mask memory requirement.
• Fix crash when zooming with fingers on an empty lighttable.
• Ensure that external format size limits are enforced during export.
• Some CSS fixes on color, contrast, positioning of combo-boxes, check-box size, scrollbars and progress bars.
• Fix JPEG APP1 header (skip 6-byte header).
• Fix some missing translations in notebook tabs.
• Use a color-managed background for color balance rgb module sliders.
• Light up midi modifier keys when shift/ctlr/alt are pressed.
• Some speed improvements (tuned compiler options, some optimized routines)
