This is a nightly build of Darktable.

You can use this if you want to try new features without waiting for releases. From time to time, in development builds, old difficult-to-reproduce bugs are fixed, but it is also true that in the development process with the introduction of new complex code, the stability of the program may suffer compared to official releases, so use it with caution!

Also, new versions can make changes to the database schema, so it's best to run them with a separate library.

The AppImage package is compatible with distribution releases that have glibc version 2.35 or higher. For example, if we consider some popular distributions, Ubuntu 22.04, Debian 12, Fedora 36 and newer releases are compatible.

The *.AppImage.zsync file is not intended to be downloaded and used locally. Just ignore it. This file contains technical information required by AppImage auto-updaters such as AppImageUpdate.

The Windows package requires Windows with UCRT (Universal C Runtime), which is shipped with Windows 10+. Darktable should also work on Windows 8.1 on condition that you install this runtime yourself.

The macOS *-x86_64.dmg package requires at least macOS 13.5 (Ventura), the *-arm64.dmg package requires at least macOS 14.0 (Sonoma).

Please help us improve Darktable by reporting any issues you encounter! 😉

Please note that the darktable documentation is not currently complete for release 4.8
and contributions are greatly appreciated. Please see the
project documentation
for more information on how to contribute.

The Big Ones

The following is a summary of the main features added to darktable
4.8. Please see the user manual for more details of the individual
changes (where available).

• Introduced the color equalizer module to control
  hue/lightness/saturation based on colors. This is a (partial)
  scene-referred replacement for the legacy color zones module.

• Two new modules have been introduced to support image composition.

  • Enlarge Canvas: As the name implies, this module can be used to add
    areas on the left, right, top or bottom of the image. The new area
    can be assigned a different color to help masking if necessary. The
    new areas can the be filled with the Retouch module by copying
    some other part of the image, using Liquify if the area is small
    or the new module overlay.

  • Overlay: This module can be used to add new content on the image
    by overlaying pixels from the current image or another image. The
    overlay content is defined by a drag-and-drop from the filmstrip
    to the Overlay module. This new content can be scaled, rotated and
    shifted horizontally or vertically. Using a mask, it can be used to
    fill an area created by the Enlarge Canvas or to add some new part
    into the image using masking. A common example is to overlay
    multiply pictures of a firework to create a bigger one.

• Implemented a toggle switch for the darkroom mode, forcing the
  pixel-pipe processing to use the whole image data instead of just the
  area displayed. This allows the user to inspect processed data
  without errors introduced via internal scaling, and equals what we
  get by exporting in "high quality resampling" mode.

Performance Improvements

• Rewrote the clustering code in map view for dramatically faster
  performance on large collections (mapping should now be usable with
  more than one million geotagged images selected).

Other Changes

• Changed the sort order of tags to a natural and case-insensitive order.

• Added Apple Keychain password storage backend for macOS devices.

• Collect module sorting has been integrated into the module's header
  instead of a preference. All collections can now be sorted easily by
  a single click on the sort button.

• Removed "unrestricted" mode from darktable's preferences resources
  for safety. This setting has been proved to be unsafe in many
  cases. It can still be enabled via the resource file if needed.

• Added buttons next to the snapshots to allow restoring it as the new
  history. Also, the snapshots are now supporting drawn masks. It is
  possible to visualize the difference between the main darkroom view
  and a snapshot with different masking for example.

• Using Right-Click on color label icons (bottom toolbar of
  lighttable) it is possible to add a description to color
  labels. This is an handy way of remembering the color label usage in
  the workflow.

• Removed the AI options in color calibration module because of
  mediocre quality.

• It is now possible to import images in-place in a GVfs mount on
  GNU/Linux.

• Added a dashed outline of the currently selected area in the print view.

• Added a few more EXIF fields to the image information module: White
  balance, exposure program, flash and metering mode. These get
  filled automatically for new imports. For existing photos, please
  perform a "refresh EXIF" on the selected images.

• Added Windows credential manager password storage backend.

• Added mask blending to the highlights reconstruction module.
  The generated raster mask holds the amount of reconstructed data and
  can be used with all algorithms.

• Color picker positions are defined by image coordinates instead of output.
  They will stay at the same location, whatever distorting modules are used.

• The history autosaving might be disabled because of slow drives, this is
  now done per image instead of globally.

• Added support for DNG files requiring the CameraCalibration tags for
  correct white balancing. (Some google pixel cameras for
  example). Requires re-reading exif metadata.

• Improved efficiency of the quick access panel by allowing modules to
  be reset and presets to be applied without opening the full module.
  Added more controls by default to further reduce the need to leave
  the panel while editing.

• Added more collection types and filters for flash, white balance,
  exposure program, metering mode and image grouping.

  Removed the old image grouping collection type and filter, which gave
  confusing results.

• Added support for CMYK profiled histogram.

• The map view can now be scrolled with the arrow keys
  (left/right/up/down) in small steps and in combination with
  Ctrl in bigger steps.

Bug Fixes

• Fixed copying of multiple instances to ensure the proper order is applied
  when pasting to a new image.

• Fixed raw chromatic aberration on Clang based systems.

• Fixed backthumb crawler for deleted history. We make sure that the
  crawler is aware of a deleted history and so will regenerate the
  thumbs as expected.

• Fixed drawn masks visualizing in darkroom after pixelpipe module have
  changed. The drawn masks will now be properly adjusted if there is
  new distortion on the pipe, for example. This was not the case until
  one was editing the mask.

• Fixed memleak while importing avif images.

• Fixed mask blending for sraw images while in IOP_CS_RAW colorspace.

• Fixed OpenCL device locking for modules calling dt_dev_pixelpipe_process().

• Fixed the UI becoming unresponsive due to very large history.

• Fixed UCS colorspace maths, avoiding div-by-zero and out-of-gamut errors.

• Fixed a number of issues with guided filter blending and internal mask
  distortions.

• Fixed some issues related to cropping module and output/export
  dimensions.

• Fixed export processing when high quality is disabled and upscale is
  set.

• Fixed camera mounting when GPhoto2 internally reports a single
  attached camera multiple times.

• Fixed a issue preventing export to recent Piwigo's version.

• Fixed many stability issues for better overall robustness.

Lua

API Version

• API version is now 9.3.0

Bug Fixes

Add action support for Lua

Other Lua changes

• Upgraded internal Lua to 5.4.6

• Added duplicate_image_with_history function to darktable.database

• button widget - added halign member to horizontally position the label

• button widget - added image member to use an image as the button label

• button widget - added image_align to horizontally position the image

• box widget - added expand member to control cells being expanded to fill the width of the box

• box widget - added fill member to control if the widgets fill the cell

• box widget - added padding member to control padding size of the cells

• added active_preset member to darktable.gui.libs to get the lib's active preset name

Notes

• Exporting with up-scaling and whithout using the high quality option
  will result in corrupt images.

• When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific
  metadata (e.g. geo-tag or creator) is not currently possible. For
  AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any
  metadata fields unless the user selects all of the checkboxes in the
  export module's preference options.

• Release 4.8 drops support for macOS versions older than 13.5.

When updating from the stable 4.4 series, please bear in
mind that your edits will be preserved during this process, but the new
library and configuration will no longer be usable with 4.4.

You are strongly advised to take a backup first.

Important note: to make sure that darktable can keep on supporting the raw file format for your camera, please read this post on how/what raw samples you can contribute to ensure that we have the full raw sample set for your camera under CC0 license!

Since darktable 4.6.0:

• 606 commits to darktable+rawspeed
• 57 pull requests handled
• 12 issues closed

The Big Ones

• Documentation is now complete for darktable 4.6 including translation
  into Ukrainian, Polish and Dutch.
  See https://www.darktable.org/resources
  for details.

Performance Improvements

• Fixed some OpenCL code paths that could produce garbled or unprocessed
  output without reporting the issue back to the pixel-pipe.

Other Changes

• Image discovery from the import dialog is now performed
  asynchronously. This means that a long parsing (due to using recursive
  mode in a directory with a huge number of sub-directories and
  files) can be interrupted by selecting another place/directory
  or un-checking recursive mode.

Bug Fixes

• Fixed an issue with importing images in recursive mode. Using this
  mode without having first selected a directory could freeze darktable due
  to it having to parse the whole disk (though it would recover eventually).

• When importing images in recursive mode, the thumbs for
  images discovered in sub-directories are now properly displayed.

• Fixed memory and resource leaks in the QOI image loader.

• Fixed RGBE image loader.

• Fixed possible issue with guide lines not being displayed in the
  Rotate and Perspective module.

• Fixed non-persistent zoom level in culling mode when switching images.

• Fixed crashes related to details mask when running low on GPU or
  system memory.

• Fixed incorrect rendering of an initial snapshot after creating a
  second snapshot.

• Keep selected styles in the style dialog after editing them.

• Fixed collection selection for ISO, aperture and aspect ratio to work
  in all locales (independent of any locale-specific decimal separator).

• Fixed RAW Chromatic Aberrations module, which could crash due to a
  rounding issue while computing an internal buffer size. This could
  cause a buffer overflow and possibly crash darktable.

• Avoid undershoots while interpolating in Lens Correction, Rotate and
  Perspective, Retouch and Liquify modules.

• Include LibRaw fix for artifacts when decoding high-ISO Canon CR3 files.

• Fixed possible incorrect module name when applying styles, whereby the
  module name was showing garbled text.

• Fixed possible incorrect default value initialized in Lens Correction legacy
  parameter migration from version 2.

• Fixed garbled output and possible OpenCL errors for very dark regions
  in Color Balance RGB.

• Fixed OpenCL startup for various cards.

• Fixed issue where the right-click-and-drag rotation line was not being
  displayed on the image when a darkroom module was expanded.

• Fixed lighttable scrolling freeze when using a track-pad.

• Fix compatibility issues with HDR created DNG files.

• Fix possible crash when using the capture's live view mode.

• Fixed a zooming bug in lighttable culling mode where some images' area
  could be plain grey or having a very small thumb.

• Fixed some missing pipe recomputing making processing modules' graph
  (Tone Equalizer for example) not properly updated.

• Fixed several mouse scroll-wheel issues on macOS when used in
  combination with the Shift modifier key (color harmonies
  width, module height, geotagging date/time, ...).

Lua

API Version

• API version is now 9.2.0

Bug Fixes

• Fixed scripts_installer to handle user names with spaces on Windows.

Add action support for Lua

Other Lua changes

• n/a

Notes

• When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific
  metadata (e.g. geo-tag or creator) is not currently possible. For
  AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any
  metadata fields unless the user selects all of the checkboxes in the
  export module's preference options.

• In order to support the correct display of numbers in darktable, the
  minimum supported Gtk version has had to be increased to
  3.24.15. For people who need to build darktable with an older
  version, this can be achieved by removing line 241 of the
  darktable.css file on your system. See
  #13166.

• Starting with release 4.4 a new support policy regarding macOS
  versions has been put in place – darktable releases will now only
  support those macOS versions that are also supported by Apple.
  Release 4.6 therefore drops support for macOS versions older than
  12.5.

• 49 issues closed

Please note that the darktable documentation is not currently complete for release 4.6
and contributions are greatly appreciated. Please see the
project documentation
for more information on how to contribute.

The Big Ones

The following is a summary of the main features added to darktable
4.6. Please see the user manual for more details of the individual
changes (where available).

• Editing history is now periodically auto-saved (every 10 seconds)
  while editing images in the darkroom view. The auto-save interval can
  be changed (via a preference) or auto-save can be disabled entirely
  (by setting the interval to 0).

• A new processing module rgb primaries has been added. This module can be used
  for delicate color corrections as well as creative color grading.
  It allows the red, green and blue primary colors to be moved around
  using "hue" and "purity" controls.

  The underlying pixel operation is essentially the same as channel mixing.

• In addition, the sigmoid module now includes a new primaries section,
  which can be used to gracefully handle difficult lighting situations
  (e.g. LEDs) and tune the overall look of the image. Modifying these
  parameters can provide pleasing sunsets, improved skin tones etc.
  This feature can only be used with sigmoid's per-channel mode and is
  loosely based on ideas from Troy Sobotka's AgX
  and related work in the Blender community.
  The included "smooth" preset should provide a good starting point
  for further corrections using this feature.

• When working with the liquify and retouch modules, the full uncropped
  image is now always shown, with any crop indicated by displaying an overlaid
  rectangle. This allows for cropped-out parts of the image to be used without
  having to first disable the crop module and re-enable it when finished.

• When panning or zooming in the darkroom view, a low resolution placeholder
  used to be shown until the image was fully recalculated for the newly-visible
  region. Now, if any part of the previous view is still visible, that part will
  be immediately shown in high quality, with only the remainder of the image
  being temporarily shown in low quality until the pipe has finished.

  This has been achieved as part of a complete reworking of the darkroom image
  display, which has also removed some annoying jumps when
  replacing the low resolution placeholder with recalculated image data,
  or when switching between full and cropped view
  (when the crop, retouch or liquify modules are (un)focused).

Performance Improvements

• OpenCL is now initialized in the background immediately after launching
  the darktable UI, with progress indicated by a series of toast messages.
  Previously, this was done before the main UI was launched, which
  could lead to significant delays (sometimes more than a minute) between
  the user opening darktable and anything appearing on-screen, making
  it appear as though darktable had failed to start. Note that processing
  will be slower (since darktable will only use the CPU) until OpenCL is fully
  initialized.

• An OpenCL code path has been implemented for lens correction using embedded
  correction metadata.

• Image display speed in the map view has been increased by 25%.

• Export speed has been improved for JPEG 2000 and B&W TIFF images.

• The chromatic aberrations module is now approximagely 10% faster when
  run on the CPU.

Other Changes

• The hot pixels module now supports monochrome images.

• The internal compositional guide widget has been removed from the retouch
  module as it is not required (you can still display the guide globally).

• A long-running import session can now be canceled by clicking on the cross
  in the progress bar on the bottom left of the screen.

• Auto orientation is now supported when importing AVIF/HEIF images
  (requires at least libavif 0.9.2 and/or libheif 1.16.0).

• It is now possible to visualize raster masks in the same way as other
  mask types by clicking the mask visualization icon.

• The dual demosaic mask visualization and performance have been improved.

• It is now possible to manually define additional vignette correction via
  the lens correction module.

• The linear ProPhoto RGB color space can now be selected in the LUT 3D module.

• The following changes have been made to the OpenCL implementation:

  • Benchmarking code has been removed as it no longer produces valid
    results on today's computers.

  • The "pinned memory transfer" option has now been removed from the
    preferences dialog, though it can still be set on a per-device basis.

  • A new option "use all device memory" has been added to the preferences
    dialog. Select this option to use all GPU memory, with the exception
    of a 600MB "headroom" which is left free for use by other applications.
    A similar option was previously available in earlier versions of darktable,
    however the headroom is now increased to 600MB to account for greater
    use of GPU acceleration on modern systems.

  • A new set of options have been added to the preferences dialog, to allow
    selection of desired OpenCL drivers.

• A built-in "Display P3" color profile has been added for use in input,
  output, display, working and soft-proofing profiles.

• The highlight reconstruction module can now be used for all non-raw files.

• The scroll speed in the filmstrip can now be increased by
  holding Shift while scrolling (filmstrip will move by half
  of the visible images at a time). Holding Ctrl while scrolling
  changes the number of images shown (zooms the filmstrip) and thereby also
  changes the speed achieved when holding Shift.

• Exported PNG files now embed a CICP (Coding-Independent Code
  Points) encoded color profile in addition to ICC where possible.

• Exported AVIF files now no longer embed a superfluous ICC profile if the
  color profile can be encoded as CICP.

• Improved scaling and placement of images in the culling view now make
  better use of available screen space.

• When hovering over the sample patches in the global color picker module
  those areas are displayed on the central image and on the histogram (if
  the corresponding option is selected). It is no longer necessary
  to have the color-picker activated when doing this. This enhanced behavior
  is useful, for example, when color grading.

• It is now possible to display a tooltip for a slider or drop-down
  and a separate tooltip for the button to its right (commonly a
  color picker button). This was not possible in previous versions
  of darktable, and was an issue where the button was not directly
  linked to the slider (for example, a button for mask display).

• Holding the Ctrl key while double clicking a slider or
  drop-down in a processing module now restores any auto-applied
  preset.

• Where multiple drawn shapes are grouped (e.g. in a module's mask)
  the mask manager module now displays a tick mark in front of the
  active combination mode (in the popup menu) when right-clicking one of
  the consituent shapes. This is usually much easier to read than the
  "Venn diagram" icons in the main module UI.

• Mnemonics have been added to dialog boxes and default actions have been
  assigned, so that pressing Enter will trigger the correct
  action and close the dialog.

• More OpenEXR 3.2.0 attributes can now be extracted and displayed in
  the image information module, where present.

• Lens and cameras filters have been added to the collection filters module.

• AVIF exports have been changed so that there is now no conversion to YUV
  for lossless. The quantizer selection logic has been updated and
  "lossy" is now the default.

• The content of the main preferences dialog is now (almost) entirely taken
  from a single definition file (darktableconfig.xml.in) making its layout
  much easier to modify.

• The drop-downs in the preferences dialog now use the same (bauhaus)
  widgets as the drop-...

Bug Fixes

• Graduated Density : Fix density computation for negative EVs.

• Fixed wrong allocation of OpenCL image buffers for blending in
  DEVELOP_BLEND_CS_RAW.

• Fixed roi_in calculation in highlights and RAW Chromatic
  Aberrations modules.

• Fix snap to grid for cm/inch units in print view. Only mm was
  properly handled.

• Fix issue where the highlight reconstruction method was reset to
  clip when applying a style from the lighttable.

• Fix loading some image format using GraphicMagick on Windows.

• Fix some possible wrong pixels at the lower-right border of images
  due to some miscalculation in Input Color Profile & Color Balance.

• Fix retouch module ROI computation when a crop is active making some
  clone area inactive when the source was outside of the cropped
  area. This bug was only visible in darkroom main view.

• Fix positioning of demosaicer RoI in according to algorithm and
  sensor. Avoid some possible (small) black artifacts on image
  borders.

Notes

• When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific
  metadata (e.g. geo tag or creator) is not currently possible. For
  AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any
  metadata fields unless the user selects all of the checkboxes in the
  export preference options.

• In order to support the correct display of numbers in darktable, the
  minimum supported Gtk version has had to be increased to
  3.24.15. For people who need to build darktable with an older
  version, this can be achieved by removing line 241 of the
  darktable.css file on your system. See
  #13166.

• Starting with this release a new support policy regarding macOS
  versions will be in place -- darktable releases will now only
  support those macOS versions that are also supported by Apple.
  Release 4.4 therefore drops support for macOS versions older than
  11.3.

The Big Ones

The following is a summary of the main features added to darktable
4.4. Please see the user manual for more details of the individual
changes (where available).

• It is now possible to define multiple automatically-applied presets
  against a single processing module. Each preset after the first will
  be added to a new module instance immediately after the first
  instance in the pipeline.

  To better visualise which module instance corresponds to which
  preset, the module label will be automatically set to the name of
  any preset that matches the current module's parameters. If you
  subsequently alter those parameters, the label will be cleared,
  unless its parameters match to another preset, in which case it will
  be changed to the name of the matched preset. If the module label
  has been hand edited it will never be updated automatically.

  A new option (preferences > darkroom > automatically update module
  name) has been introduced to allow this functionality to be
  disabled.

• The default parameters of some processing modules have been reworked
  to allow them to be more easily used in copy/paste, presets and
  styles.

• Many modules have default parameters based on image metadata or
  current workflow, for example:

  • exposure: in a scene-referred workflow, the exposure is adjusted
    using the Exif exposure compensation value,
  • denoise (profiled): set based on camera and ISO,
  • lens correction: set based on camera, lens, focal length, focus distance,
  • base curve: set based on the camera maker,
  • white balance: set based on Exif metadata,
  • orientation: set based on Exif metadata,
  • color calibration: set based on Exif metadata

  For all of these modules it is now possible to paste settings while
  ensuring that the proper image metadata is used to set the module
  parameters. This is achieved by selecting the "Reset" column in the
  preset and style dialogs, which makes the module behave as if its
  reset button has been clicked.

  When creating or editing presets, a new option, "reset all module
  parameters to their default values", has been added. Choose this
  option to auto-add modules to matching images while retaining their
  default parameters (including any set based on image metadata).

  This functionality has allowed us to clean up a number of
  module-specific hacks that previously achieved similar functionality
  (albeit in a more limited way).

• The default workflow configuration option (preferences > processing >
  auto-apply pixel workflow defaults) has now been adjusted to
  incorporate the previous chromatic adaptation workflow setting and to
  include the new sigmoid module. Options are now as follows:

  • scene-referred (filmic) -- default
  • scene-referred (sigmoid)
  • display-referred (legacy)
  • None

  With these new options, the color calibration module and
  scene-referred module order will be automatically applied for all
  workflows except "display-referred (legacy)", which will continue to
  use only the white balance module for chromatic adaptation. The
  value in brackets represents the default module used for tone
  mapping (filmic/sigmoid). In the legacy mode, base curve will be
  used for tone mapping and in "none" mode, no tone mapping module
  will be applied.

• The scopes module now has a new color harmony overlay option in RYB
  vectorscope mode. You can choose from 9 different color harmonies:

  • Monochromatic
  • Analogous
  • Analogous complementary
  • Complementary
  • Split complementary
  • Dyad
  • Triad
  • Tetrad
  • Square

  These will show as overlays on top of the vectorscope to tell you
  where the "harmonic" colors are. You can rotate the overlays by
  scrolling with your mouse.

  Color harmony guides can be used along with the global color picker
  module to guide you in shifting your image's colors to fit a given
  color harmony -- think of them like crop composition guides, but for
  colors.

• A global right-click-and-drag operation has been added to
  allow image rotation to be corrected without first opening the
  rotate and perspective module. This operation can be used as long as
  the currently-focused module does not already use that shortcut for
  another purpose.

• Drawn mask functionality has been completely overhauled with a large
  number of changes and fixes:

  • The "brush smoothing" and "pen pressure" options have been moved
    from the global preferences dialog to a new collapsible
    "properties" section in the mask manager, so that they can be
    changed while drawing and can be assigned shortcuts.

  • The drawn mask shape size/feather/hardness sliders in the mask
    manager now use a logarithmic scale and scrolling over them makes
    relative adjustments, just like Shift+scroll over the
    shape itself. As with other sliders, Ctrl or
    Shift can be used to make fine or coarse adjustments
    (similarly with shortcut fallbacks enabled). Shortcuts assigned to
    the sliders can be used to adjust brush size/hardness while
    drawing.

  • A fifth set operator has been added to the mask manager to allow
    drawn shapes to be combined in "sum" mode. This allows repeated
    brush strokes with low opacity to be layered on top of each other
    to increase the strength of the mask. This mode is now the default
    for brush shapes.

  • It is now possible to change the set operator (mode) for all
    shapes in a group from the right-click menu in the mask manager.

  • Some actions in the mask manager menu previously could be
    activated even though they would have no impact on the image in
    some contexts. The move up/down actions are therefore now disabled
    for the first and last element in a group respectively, and it is
    no longer possible to choose a set operator (mode) for the first
    element in a group.

  • The sort order of the shapes in mask manager groups has been
    reversed so that the lowest ranking shape is at the bottom of the
    group. The sort order of shapes outside of a group has also been
    changed for consistency.

  • It is now possible for all mask types to be added continuously in
    the mask manager.

  • Fixed an issue where the brush was not properly displayed after
    being created from the mask manager, and a crash when creating
    gradients from the mask manager has also been fixed.

  • For all shapes the editable state is now properly set after
    creation making it possible to move and resize the different parts
    of the shapes.

  • Fixed a display issue when editing a shape name in the mask manager.

  • Fixed the state of the set operators in the mask manager -- when
    moving a mask up/down we now ensure that the first mask has no
    operator and that the second one always has an operator assigned.
    If no operator has been set yet the default (union) operator is
    used.

  • When using a shortcut to add shapes to a drawn (blending) mask the
    blending mode will automatically switch to "drawn mask" or "drawn &
    parametric mask", depending on what it was before, so that any newly
    created shape will actually affect the image.

  • In the drawn mask blending mode there used to be an "invert mask"
    option that had the same functionality as the "toggle polarity" option.
    Since both were doing the same thing, "invert mask" is now removed.

  • The drawing of masks has been reworked to ensure that all types of
    masks are drawn in the same way -- the central area, border, and
    highlighted segments are now displayed consistently. The highlighted
    segment is now more visible, especially for the brush mask, where
    the highlighted segment was barely distinguishable due to a bug.

  • In the style and copy/paste dialogs a new column has been added to
    show whether a module uses a mask (drawn/parametric/raster) using
    ...

The Big Ones

The following is a summary of the main features added to darktable
4.2. Most of these features are described more fully in the user manual.

• New Sigmoid display transform module, which can be used in place of
  the filmic and base curve modules.

• Two new algorithms are provided in the highlight reconstruction module:
  "inpaint opposed" and "segmentation based". The "inpaint opposed"
  algorithm has proved to be very stable and provides good results in
  many images, so it replaces "clip highlights" as the new default algorithm.

• The pixelpipe used for image display in the darkroom view has been reworked
  so that it can be used elsewhere (darkroom view, second display window,
  duplicate manager, style preview, snapshot routine). This has allowed
  for code de-duplication as well as enhancement of many of these features
  (see below).

• The second darkroom image window has now been enhanced to support both
  the focus peaking and ISO-12646 color assessment modes.

• The snapshot module has been entirely reworked so that, instead of using a
  fixed screen capture it now uses a dynamically generated view using the new
  pixelpipe functionality. This means that it can now be zoomed and panned
  with keyboard/mouse.

• The duplicate manager previously used a different pipe routine to calculate
  its previews (i.e. when long-pressing on a duplicate image thumbnail) which
  often meant that the displayed duplicates differed from the main darkroom
  view in subtle ways. Use of the new pipe routine now means that these previews
  will be identical to those produced during darkroom editing.

• It is now possible to preview the effect of a user-generated style on
  an image before applying it. Simply hover over the style name in either
  the lighttable styles module or the darkroom quick-access menu and a
  new tooltip will appear, showing the image with the style applied along
  with details of the modules that are included.

• Some cameras record lens correction information within the image
  EXIF metadata. The lens correction module has been enhanced so that
  it can extract this data and use it to correct lens distortions.

• darktable is now able to read and write JPEG XL images

• Processing and utility modules have been altered so that if a module is
  not entirely visible when expanded, it will be automatically scrolled
  until the entire UI is visible on screen.

  For users who currently use the "scroll to the top when expanded" preference
  setting to achieve this effect, this change may provide a better alternative.

  As part of this change, a new animation effect has been added when
  expanding/collapsing modules. The speed of the expand/collapse animation
  can be controlled via a preference setting
  (preferences > miscellaneous > duration of ui transitions).
  Set this to zero to disable the animation.

• The pixelpipe caching functionality has been completely overhauled. More
  cachelines are used with an improved hit-rate while controlling
  the total amount of memory used, leading to a significantly faster
  interface.

• The slideshow has been rewritten for a better user experience.
  A small preview is displayed while the full image is computed
  to provide feedback to the user that something is being done in
  the background.

• A new drop-down menu has been added to the top filter bar to allow
  filters to be easily added and removed. Some range widgets have been
  removed from this list as they are not easily readable on the top bar.

• The UI of the range rating filter widget has been reworked for better
  readability. This revised widget is designed to be easier to use
  and more efficient.

Other Changes

• Added support for manipulating shapes without using the mouse scroll-wheel
  (for tablet users). The mask manager has been enhanced with a new collapsible
  section containing controls for changing shapes properties.

  It is also possible to change a property that is shared by a group of shapes.

  The circle and ellipse shapes have also been enhanced with new on-canvas
  controls to change the mask size and feathering.

• WebP read support has been added.

• Embedded ICC profiles are now supported in exported WebP files.

• Double-clicking on a notebook tab now resets all widgets within that tab.

• Regional date/time format is now supported in thumbnail tooltips.

• Lua commands are displayed in a widget's "action" tooltip.

• The SSE code path has been removed from the white balance and
  output color profile modules as compiler defaults now provide a
  similar speed.

• Added support for JFIF (JPEG File Interchange Format) file extension
  (which is an extension of the JPEG standard).

• The preference to auto-apply a sharpening has been removed. For users
  who still require this functionality, it can be easily achieved with a
  user-generated auto-applied preset.

• Added support for updating existing pictures in Piwigo export.

• All white balance presets have been migrated to an external JSON file.
  This should not affect the module's operation.

• The preferences to set the layout of the "color balance module" and the
  colors of the "white balance" module have been removed from the global
  preferences dialog, as these controls are already available directly within
  the respective modules.

• Improved profile support for AVIF & EXR format. Also relax AVIF
  reader support by not requiring full compliance.

• The current collection image count is now shown in the top bar beside
  the image filters meaning that it is available even when the top hinter
  area is hidden.

• Attempt to obtain the color-space for PNG files from the cICP chunk. This was
  added in a recent revision of the PNG spec, so we take advantage of
  it, if present.

• Reading of 16-bit half float for the TIFF format is now undertaken using
  the Imath library.

• The format and storage parameters in the export module can now be mapped
  to shortcuts.

• Introduced balanced "OpenCL vs CPU" tiling. This makes it possible to
  use CPU tiling if there is not enough memory on the OpenCL card
  (which would require a lot of tiles to be handled on the card). In the
  end, the large number of tiles plus the overlapping area would make
  the use of the OpenCL code path slower (or much slower) than
  handling the image without tiling on the CPU.

• In preview mode (when pressing Ctrl+w) the image
  information overlay display block is no longer shown by
  default. Moving the cursor within the top half of the preview image
  will cause the overlay to appear, and it will then disappear again
  after a brief period.

• Light patterns are set for Behringer b-control midi rotors
  (BCR2000/BCF2000)

• Fixed reading of EXIF metadata when importing EXR files (if desired,
  existing files must be re-imported, as it is not possible to refresh
  metadata).

• Added support for scrolling through a module's presets using shortcuts.

• Panels now use "natural sizes" by default, meaning that their initial
  size adjusts according to screen resolution.

• The geo-tagging module now better supports narrow side-panels by
  wrapping rather than ellipsizing text.

• More actions have been added to the main help screen (displayed by
  pressing the h key).

• The lensfun library is now a mandatory dependency. This ensures
  that all darktable builds correctly include the lens correction module.
  This also means that an edit made using this module won't be inadvertently
  lost due to missing build dependencies.

• It is now possible to assign shortcuts to the "currently focused"
  processing module. This allows a common set of shortcuts to be
  created and reused in multiple modules simply by focusing that
  module. For example a single key shortcut applied to the "first
  slider" will affect the "exposure" slider when the exposure module
  is focused, and the "rotation" slider when the "rotate and
  perspective" module is focused. Similar functionality can be used to
  affect the "nth" slider, combobox, button or tab as well as the
  focused module itself.

• Right-clicking on a module header in the quick access panel now allows
  ...
