Other 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

The Big Ones

The following is a summary of the main features added to darktable 4.0. These features
are described more fully in the user manual and accompanying blog post.

• Color and exposure mapping

  A new feature in the "exposure" and "color calibration" modules allows you to
  define and save a target color/exposure for the color pickers, in order to
  match any source object in the image against an arbitrary target
  color. This can be used to perform white balance
  (chromatic adaptation) against non-gray objects of known color, or to
  ensure the color consistency of an object across a series of images.

• Filmic v6

  Filmic v6 introduces new color science. This change removes the mandatory desaturation
  close to medium white and black and replaces it with a true gamut
  mapping against the output (or export) color space. This allows for more
  saturated colors, notably in blue skies.

  For users who still prefer the "desaturated highlights" look,
  you can still do this by disabling chroma preservation, but v6 adds a
  hue handcuff to prevent the traditional hue shift that comes with this
  method (where saturated blue skies degrade to cyan and saturated red to yellow).

  This gamut sanitization is the third and last to be added to darktable,
  which now has a fully-sanitized color pipeline from input (color calibration),
  through artistic changes (color balance rgb) to output (filmic v6). Users
  can now color-grade pictures safely in the knowledge that invalid input
  colors can be recovered in the least destructive fashion possible early
  in the pipeline, and valid colors can't be pushed out of gamut along the pipeline.

  Note: If modules are applied after filmic in the pipeline, they
  don't benefit from this gamut mapping and rely on LittleCMS2 (if
  enabled) at the final export stage, which does not gamut map as it
  should, and probably never did.

• Guided laplacian highlight reconstruction

  A new "guided laplacian" method has been added to the "highlight
  reconstruction" module. This uses an iterative and multi-scale wavelet
  scheme to extract valid details from non-clipped RGB channel(s) if any,
  uses these details to guide the reconstruction of clipped channels, and finally
  propagates the color gradients from neighboring valid regions using
  edge-aware color diffusion. This limits color bleeding through edges
  (preventing green leaves from bleeding color in the reconstruction of clipped
  blue sky, for example).

  A noise setting allows Poisson noise to be added to reconstructed highlights,
  in order to help blend them into noisy high-ISO images.

  This method is only available for Bayer sensors and cannot be adapted
  to X-Trans sensors.

• Introducing the darktable Uniform Color Space 2022

  The darktable UCS 22 is a perceptually uniform color space designed
  from psychoperceptual experimental data specifically for the purpose
  of artistic saturation changes, as performed in the color balance RGB module.
  It uses a brightness-saturation scheme that compensates for the Helmholtz-Kohlraush effect
  (accounting for the contribution of colorfulness in perceived brightness)
  and allows an efficient gamut-mapping against pipeline RGB at constant
  brightness. It will make the saturation control in color balance RGB
  better behaved.

• UI Rewrite

  The UI has been completely revamped again to improve look and consistency.
  Padding, margins, color, contrast, alignment, and icons have been reworked
  throughout.

  Collapsible sections within modules have also been redesigned so that
  their functionality is more obvious and better-looking.
  New collapsible sections have been added to avoid
  cluttering the UI in the following modules:

  • channel mixer rgb
  • exposure
  • color calibration

  The vignetting module has been split into two sections for clarity.

  Superfluous sections have been removed from the "crop" and "white balance".

  Support has been added for the IPAPGothic font.

  The module-description tooltips have been reworked to ensure better layout.

  Finally the default theme has been changed to Elegant Grey. The
  darktable default is now in line with the theme recommended by the
  team.

• Performance and OpenCL support changes

  All performance and OpenCL settings and pixelpipe optimizations have been
  fully reviewed and updated. Many new optimizations have been
  added and the user preferences have been simplified.

  All configurations are now per-device allowing each OpenCL
  device to be tuned separately.

  Performance configuration is now applied at runtime and no longer
  requires darktable to be restarted when changed.

  Some modules had incorrect or overly conservative tiling factors, which made
  darktable unnecessarily slow (since tiling was used when it was not required)
  The followimg modules have been updated

  • demosaic (X-Trans)
  • retouch

Other Changes

• Color glossary

  The global color picker tool (in the darkroom's left sidebar) now displays
  the name of the picked color in the tooltip. This feature was
  requested by several color-disabled photographers, to assert the
  perceptual validity of their editing for an average observer.

  The color vocabulary contains 76 entries: 15 hues × 5 lightnesses +
  neutral (gray). It does not separate across the chroma axis, so all
  colors are registered the same no matter their colorfulness.

  The vocabulary also contains average skin colors for 3 body
  parts (forearm, forehead and cheek) of 6 ethnicities (Chinese, Thai,
  Kurdish, Mexican, Caucasian, African-American). These values come from
  the academic databases of cosmetology and dermatology available at the
  time of programming. They are only valid for a D65 illuminant and for
  an exposure setting that anchors diffuse white at 92% relative
  luminance.

• A new "contrast" parameter has been added to the guide line overlay
  settings, allowing for better visibility of the lines over images.

• A new "collection filters" module has been introduced, designed to be easier
  to use than the filtering in the current "collections" module.

  The new module allows the current collection to be sorted and filtered using multiple
  criteria. Each sort/filter rule can be pinned, which duplicates the appropriate control
  on the top tool bar for quick access.

  The following filters have been implemented (more to come in the next version):
  color labels, text search, date-time filters, exposure, ISO,
  focal length, aperture, aspect ratio, filename and extension,
  grouping, history, local copy, module order

  Presets can be created and a history button also allows previous configuration to be retrieved.

  All-new text and color filter widgets have been implemented.

• The "recently used collections" module is now incorporated into the
  "collections" module as a "history" button

• The darkroom's module search facility has been enhanced to also match on
  any user-defined module names.

• Support for EXR 16-bit (half) float export has been added.

• All usage of dates/times have been reworked to better support
  time-zones and differing operating systems. Support for
  milliseconds has also been added.

• All presets in the "tone equalizer" module have been updated to use
  scene-referred blending modes.

• The new input system introduced in version 3.8 now handles
  simultaneous shortcut presses and the responsiveness is
  greatly improved.

  MIDI configuration parameters are now specified in darktable
  resource files.

  Slider step sizes have been standardized and can now be
  configured individually.

  Extra pen tablet button clicks are now treated as key presses so that
  they can be used in shortcuts.

  Support for gamepad triggers has been added (treating them as buttons)
  allowing them to be used as shortcuts.

• Modifiers (Ctrl/Shift/Ctrl+Shift)
  can now be used when dragging sliders, to modify the precision of the
  value changes.

• When using the "copy" and "move" functionality in the lighttable, the last
  directories are remembered independently for each operation.

• It is now possible...

Since darktable 3.8.0:

• More than 160 commits to darktable+rawspeed
• 75 pull requests handled
• 55 issues closed

The Big Ones

• Two new languages are now available for the documentation: Spanish
  and Dutch. This brings the total number of translations to six.
  Thanks to all the translators for their hard work.

Other New Features And Changes

• Speed up the retouch's heal tool by using better parallelism.

• Add new variable $(DARKTABLE_VERSION).

Bug Fixes

• Fix control and feather points for path and brush shapes when editing
  using zoom > 200%. The editing is now smooth and no longer jumps as the
  mouse is moved.

• On the lighttable view, fix Shift-click when selecting a range - at least one
  image must first be selected.

• Fix expansion of some variables on Windows.

• Fix SVG rendering by computing proper dimension in the watermark module with
  libsvg 2.52.

• Fix printing when the export module is set to scale mode. This was caused by
  a bug in the interaction between export/print.

• Fix print module image layout display when using inch unit.

• Fix yellow border for selected grouped images.

• Fix some tag export issues.

• Fix crash on Windows when importing from a folder containing special
  characters.

• Fix mouse-over thumbnail display when leaving the lighttable from the
  bottom - ensure that the thumbnail stops being highlighted.

• Remove the double-click hint in the crop module for committing parameters.
  This functionality was removed in darktable 3.8.0.

• Better layout for the star and rejected icons.

• Fix some refresh issues on the guide overlays menu - ensure that the popup
  shows the current settings after they have been changed via a keyboard shortcut.

• Fix guide lines in the rotate and perspective module - ensure the
  guides are displayed only within the cropped area.

• Fix Piwigo export for new version of Piwigo which now uses a lounge
  for new images. We now flush it to ensure the images are assigned to
  their corresponding album.

• Fix handling of circle/ellipse sources in the retouch module. Shapes can now be
  moved immediately after placing them via drag+drop.

• Fix a bug in rotate and perspective that was preventing removal of
  the last manually drawn line.

• Fix multiple issues in tagging module. Some UI interactions have
  been reworked to be closer to what a user would expect.

  Also, some new keys have been added:
  shift-enter attach selected tag, reset entry and give it the focus
  shift-left collapse the entire tree

• Fix multiple drag+drop issues on the lighttable that were causing crashes.

• Fix a possible crash with very large up-scaling at export.

• Rework the history items on thumbnail tooltips.

• Rework the GUI for the copy / paste of history items. The on/off
  status icon has been removed from the labels and replaced with a specific
  "on/off" column.

• Fix some demosaicer issues specific to AMD OpenCL drivers.

• Fix possible crash in styles module for style names containing a
  slash.

• Add option to enter the new module instance name automatically when
  duplicating a preset.

• Fix Filmic RGB graph update when used in the quick access panel.

• Restore shortcut for creating a virgin duplicate in the lighttable view.

• Allow presets in the tagging module to append the tags instead of replacing them.

• Fix tooltip on mid-tones vs extreme luminance saturation sliders in Filmic RGB.

• Fix crop adjustment in rotate and perspective module when preview
  down-sampling is active. Movements were amplified making the
  adjustment harder and the clicked location was not constant when
  dragging the crop area.

• Fix writing XMP metadata in AVIF format.

• Fix importing from SMB shares mounted using gvfs.

• Fix possible color shifting when activating lens correction on a
  monochrome image.

• Fix $(RATING_ICONS) variable substitution - now displays an "X" when rating
  is 0 instead of an empty string.

• Add some missing variable substitutions in the displayed list.

• Fix reset button in metadata editor. The metadata entries were properly
  removed from the selected pictures but the module display was not
  refreshed.

• Fix enabling processing modules from a shortcut. The module is no
  longer given focus when activated, matching the "click" behaviour.

• Fix automatic tab selection when opening the preferences in non English
  languages.

• Improve the unknown DNG illuminant handling.

• Fix high quality export when the export size is specified "by scale".

• Fix some shortcuts being ignored when applied to a widget in an inactive
  or unfocused popover dialog.

Lua

Notes

• We now display a large red message for cameras with missing
  samples. The cameras that were removed in 3.8.0 have been added back
  to darktable for a short period of time.

  If you see such a message this means that your camera is missing samples. If
  you do nothing, support will be removed for good in the next major darktable
  release.

  Read this post for more information.

  The samples must be uploaded here https://raw.pixls.us/.

When updating from the currently stable 3.6.x series, please bear in
mind that your edits will be preserved during this process, but the new
library and configuration will not be usable with 3.6.x anymore.

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!

• Almost 3915 commits to darktable+rawspeed since 3.6
• 571 pull requests handled
• 265 issues closed

The Big Ones

• The keyboard shortcut system has been entirely reworked and extended to allow you
  to control darktable with other devices, for example, MIDI devices
  and game controllers. Standard keyboard/mouse shortcuts can now make use
  of mouse movements (horizontal, vertical, diagonal) as well as multiple
  button/key presses and short or long presses/clicks.

  Please note that any shortcuts you have previously created are not transferred
  to the new functionality and will need to be redefined in darktable 3.8.

• New diffuse or sharpen module, allowing you to simulate or to revert
  diffusion processes to reconstruct images from lens blur, hazing,
  sensor low-pass filter, or noise. It can also be used to simulate
  watercolor smudges, increase local contrast, simulate blooming or
  apply surface blur. Special rules can be defined to specifically
  diffuse across or along edges, as well as to avoid sharpening or
  blurring them.

• New scene-referred blurs module, to synthesize motion and lens blurs in a parametric
  and physically-accurate way. This module allows you to define the motion path or the lens
  diaphragm and then generates the corresponding blur.

• Perspective correction module has been renamed to rotate and perspective
  and now allows you to manually define correction settings by drawing lines
  or rectangles on the image (replicating keystone correction functionality
  from the deprecated crop and rotate module)

• Added support for multiple images in the print view. The page can be
  filled with multiple areas, each of which can be moved around and placed on
  the page with the ability to snap to a grid for precision.

• A new LMMSE demosaic algorithm has been introduced. This algorithm is particularly
  suited to high ISO and/or noisy images.

• The composition guides from the crop module are now available globally and no
  longer require the crop module to be activated.

• The Canon raw CR3 format is now supported (see list of supported cameras in the
  section below). This support is provided by LibRaw and requires at least exiv2 version
  0.27.4 with BMFF support activated.

• The color checker profiling tool, introduced in darktable 3.4 as part of the
  color calibration module, is now normalized patch-wise in exposure to discard the effect
  of uneven lighting and fall-off when shooting color checkers hand-held and on-location.
  This robustly decreases the residual average dE after calibration and noticeably
  helps to recover natural dark blues while preventing yellow shifts in highlights.

Other New Features And Changes

• The denoise (profiled) module now uses wavelets mode by default and its default
  settings in Y0U0V0 mode have been improved.

• Flip buttons have been added to the orientation module (functionality moved
  from crop and rotate).

• Background jobs handling has been removed from preferences.

• Much of the SSE-specific code has been removed, since compiler-generated code
  is usually faster.

• The darktable-generate-cache script now displays filenames and image IDs.

• File name matches in the collections module are now faster.

• Mask handling is faster.

• Processing module order can now be automatically applied based on image
  properties.

• Folder status is properly refreshed when a mount is changed.

• An area color picker is selectable by using a Right-Click in
  addition to the existing Ctrl+click action.

• Substitution variables have been added for image dimensions as follows:
  $(SENSOR_HEIGHT) and $(SENSOR_WIDTH) for the absolute pixel
  dimensions of the sensor; $(MAX_HEIGHT) and $(MAX_WIDTH) for the raw
  image size; and $(EXPORT_HEIGHT) and $(EXPORT_WIDTH) for the
  post-cropping final image size.

• More work on code speed-up in many different routines ensuring
  better vectorization and/or OpenMP definition. Notably, the
  split-toning, haze removal and soften modules have been improved.

• The "beginner" module group preset now takes the chosen workflow
  (display or scene referred) into account.

• The quick access panel now takes the chosen workflow
  (display or scene referred) into account.

• New sorting options based on capture, import, modification,
  last export and last print times.

• Tooltip for raster mask now includes source module information.

• The following modules have been deprecated:

  • Crop and rotate - the features of this module are now shared between the crop,
    orientation, and rotate and perspective modules.

    Note that the new crop module is now placed after the retouch module
    to ensure that the full image can be used as a source area.

• A new option has been added to allow you to choose when to start writing
  changes to the XMP sidecar files. Choose to:
  (a) never write XMP;
  (b) write XMP as soon as the image is imported; or
  (c) write XMP only after the user has edited the image in the darkroom view.

• Timezone entry has been improved in the geotagging module.

• A new preference has been added to choose the number of recent collections to display.

• Rating support has been added to the collections module making it possible to create
  presets, for example, to select the best images of 2021.

• PNG files are now supported in the watermark module.

• The values in the global color picker module are now selectable and can be copied
  to the clipboard.

• HSV has been added as an option in the global color picker module.

• The color scheme of the timeline is improved.

• The scopes module (previously named histogram) can now be moved to the
  left panel.

• Improved color rendering for waveform and parade scopes.

• A new vertical waveform scope option has been added.

• Live samples can now be displayed in the vectorscope.

• An RYB option has been added to the vectorscope.

• The lut3d module has been moved after filmic in the pixelpipe.

• Minor usability improvements have been made to the tone equalizer,
  ensuring that the cursor is shown on focus and the module is activated on scroll.

• The automatic mask tuning has been improved in the tone equalizer module.

• New "magic wand" icons are now used for the auto-tune actions in
  the tone equalizer module.

• Tiling has been enabled in the color balance rgb, diffuse and filmic rgb modules
  to allow very large images to be processed.

• When scanning for updated XMP files, the synchronization window has been improved
  to offer more choices as to how the database/XMP files should be updated.

• Added read support for HEIF/HEIC file format.

• Added support for ARM64/Apple M1 as a build target.

• Added a preference to invert the behavior of mouse scroll up/down on drawn
  mask attributes. At the same time, and for consistency, the scroll-up action has been
  set to increase all mask attributes by default.

• Added timestamp in camera import dialog for consistency with the other
  import dialog.

• The current module order is now shown in the module order module header to
  save space in the GUI.

• The "module order" entry is now moved to the end of the copy/paste dialog
  for better usability, as this option is rarely used.

• The split toning module now displays the hue in degrees for consistency
  with other modules.

• Rejected images in the lighttable view are now dimmed for clarity.

• The last selected Piwigo album is now remembered in the export module.

• For advanced users and developers, OpenCL build options are now exposed in
  darktablerc.

• The collections module now offers some new presets based on image time to
  complement the existing presets based on the import time.

• Add a borderless requirement indicator in the print module when the user's
  selected margins are below the hardware margins.

• Add an option to show all modules in the history within the active
  module group regardeless of whether or not they are currently
  enabled.

• Add a search box in preset preferences and shortcuts.

• Improved curve handling in filmic. Curve should be easier to control, as
  some side-effects of some parameters on others have been eliminated.

• Add thumbnail preview support for DNG files in import dialog.

• The darktable 3.8.0 documentation now includes four (French, German,
  Ukranian, Brazilian Portuguese) translated languages (the first time
  complete, translate...

The Big Ones

• Full rework of the import module. The new module allows you to see
  thumbnails of your images before import and makes it easier to handle
  multiple import tasks. The same dialog is now used for importing
  from disk, card or camera.

  When importing "in-place", images that are already present in darktable
  are flagged and can be automatically excluded from the import.

  Importing from a local drive won't use gphoto and so should work more
  reliably on Windows.

• A vector-scope is added to complement the current histogram,
  waveform and parade views.

• A new default demosaic algorithm (RCD) has been introduced, which should provide
  better quality than the current default (PPG) without the long run-times
  of AMaZE. the order of the demosaic algorithms has also been adjusted for clarity.

• Support for "dual demosaic" has also been added, allowing you to combine
  "RCD + VNG4" and "AMaZE + VNG4" for bayer sensors, for xtrans sensors there is
  "Markesteijn 3-pass + VNG". This allows you to use an algorithm better resolving
  fine detail and another one delivering smoother output depending on local image content.

• You can now create an opacity mask based on the sharpness of the image. This uses
  a similar algorithm to that used in dual demosaic.

• Drawn shapes are drawn on the original RAW image and then distorted through
  the pixelpipe. This previously led to, for example, circles becoming ellipses
  (due to lens distortion) after being placed on the image. All drawn shapes can
  now be pre-visualized and moved prior to placement, with full deformation
  applied. This makes the editing of masks easier fully WYSIWYG.

• A new Color Balance RGB module has been added. This can be used as a one stop module
  for all color grading work.

• A new censorize module has been added. This allows you to hide parts of the image by adding
  a blur/pixelization.

• A new crop module has been added. This new module has been added late in the
  pixelpipe and makes it possible to use cropped parts of the image for source spots
  in the retouch module, for example.

• A new section has been added to the color calibration module to allow you to calibrate
  colors using a color checker chart.

• The map module has been enhanced in a number of ways:

  • When importing a GPX the trace can be displayed.
  • Location can be set using polygons and directly created from information
    reported by Open Street Map. As a reminder, all locations
    create tags automatically for images placed into the area.

• The basic adjustments module has been replaced with the quick access panel, which
  can be used to group controls from multiple different modules in one place. Currently,
  only non-graphical controls (sliders, comboboxes etc.) can be used.

Other New Features And Changes

• The various lighttable modes can now be accessed via clear and descriptive icons
  at the bottom of the screen. These should be easier to use than the existing drop-down
  selection.

• The export module is now also accessible on the left-hand panel of the
  darkroom view.

• The mix control in the contrast equalizer module is now retained as
  module parameter. This means that no data is lost when using this slider and
  you can always change the mix later with full precision.

• The following modules have been deprecated:

  • The basic adjustments module has been replaced by the new quick access panel.

  • The vibrance module has been replaced by the vibrance control in the new color
    balance rgb module.

  • The spot removal module has been replaced by the retouch module (use
    this module in "clone" mode to replicate the spot removal functionality)

  • The defringe module has been replaced by a new "chromatic aberrations" module.
    The old module has been renamed to "raw chromatic aberrations".

• The RAW chromatic aberration module has been enhanced to support
  multiple iterations and an option to help avoid color shifting has
  been added (not activated by default).

• Scene-referred workflow is now the default, though this can still be changed in
  preferences.

• The ESC key can be used to exit the slideshow view.

• You can now Ctrl-Click on the module groups preset button to
  access the manage dialog directly.

• Many aspects of the GUI have been reworked or tweaked for a better user
  experience (combo-box alignment, padding, histogram icons, etc.).

• The color of scope views (histogram, parade, waveform) has been reworked using CSS.

• The integrated help system now points to the new user manual which is
  up-to-date for this release. Also for development builds of darktable these links will
  go to the development version of the manual. So more links have been
  added, for example, for the lighttable layout and the timeline.

  As a reminder, the new documentation is available in the following location
  (viewable online or in pdf and epub formats):

  https://www.darktable.org/usermanual/3.6/en/

• Many graphs in processing modules can now be resized with Ctrl+Scroll.
  (Filmic RGB, RGB levels, levels, lowlight, colorzones, rawdenoise,
  denoise profile, contrast equalizer).

• A new color preservation method ("norm-preserving colorfulness") has
  been added to the color calibration module.

• A simplified and more precise message has been added to notify the user
  when their database(s) are locked by another process.

• A rational function has been added to toe/shoulder controls in Filmic RGB.

• A new preference for advanced users can now be used to disable the
  module warning messages. Use at your own risk.

• Preliminary work toward full support for CR3 has begun. darktable's exif
  support can now read CR3 files if the proper exiv2 library version
  is found.

• A new color science with norm preservation under de-saturation has been
  added to Filmic RGB and a new scaled euclidean norm is supported.

• Some changes have been made to make liquify faster when editing
  nodes. Also smaller deformation stamps are now supported.

• The style of module sub-sections has been tweaked so that they stand out more.

• It is now possible to more easily manage overlapping masks. For example, it is
  possible to change an ellipse's control points when they lie within a
  larger circle or path shape.

• Easier handling of the mask controls - do not require high precision
  as mouse collision detection has been reworked.

• The preferences, "manage module groups" and import dialogs will remember and
  restore their size after closing. Their default size is designed to support
  smaller screens and it is recommended that you resize them as appropriate.

• A huge number of internal optimizations have been made throughout the code.
  For example: soften, tone equalizer, drawn masks, color picker, color space conversions.
  It is impossible to list them all

• Many speed improvements have been made for the standard CPU code path by tuning the
  OpenMP code. There are some huge gains with the new code in some
  modules. We have then removed some hand-coded SSE routines as they are not
  faster and are hard to maintain.

• The prompt that appears when exporting in overwrite mode is now optional and controlled
  by a security preference.

• An icon has now been added to module headers to indicate whether a module uses a mask.
  This allows you to quickly see which modules use a mask and to enable/disable the mask
  preview by clicking on it.

• A message is now shown when a camera is plugged and darktable is not able
  to connect to it. The general cause is that the camera is mounted by
  the OS and so is exclusively locked.

• The grey darkroom loading screen is now optional. This can lead to on-screen artifacts
  but can also be useful to quickly compare versions of an image.

• Module group presets can now be auto-applied based on the image being edited.
  This make it possible to create groups specifically to develop color,
  monochrome, RAW or Jpeg images, for example.

• Different interpolation algorithms are advised for warping and scaling modules.
  A new preference has been added to allow you to select these algorithms independently.

• RGB scene blending mode is now used for the denoise (profiled) presets.

• Parametric masks are now handled better when being reset. S...

The Big Ones

• The user manual is made available at the same time as the
  release. Note that this user manual is also the last version as a
  new project has taken over the lead on this. The goal is to have
  an up-to-date user manual by using a simpler format
  to write text for contributors. Feedback or contributions for the
  new format are welcome at https://github.com/darktable-org/dtdocs.

  Current manual (multilingual):

  https://darktable.gitlab.io/doc/

  New manual (English only):

  https://www.darktable.org/usermanual/en/

• The tethering view has been reworked and is now more stable.

• The histogram is back on the tethering view (it was disabled in 3.2
  due to lack of time)

• A new module grouping feature has been introduced. This makes the "more modules" module
  (at the bottom right of the darkroom) obsolete and this module has therefore been removed.

  The module grouping feature allows users to create their own groups
  of modules. A number of pre-defined module groups are included as presets
  (default, minimal, scene-referred, display-referred,
  all modules) as well as a new default module group tab layout (technical / grading / effects),
  which beter organizes the modules according to their purpose.

• Module masking is now enhanced for use with scene-referred workflows. A new masking implementation
  has been added, with fully unbounded blending modes, which allows parametric masking
  either in linear RGB or in JzCzHz color spaces. A boost factor slider has been
  introduced in the masking GUI so that users may set thresholding parameters above 100%
  to mask pixels in HDR images.

  JzCzHz is derived from JzAzBz, which is a perceptual color space developed
  for HDR and published in 2017, with better properties than CIE Lab from 1976,
  allowing near-perfect hue linearity, for a robust hue/saturation masking.
  A JzCzHz hue mask will produce the same output whether it is used
  before input color profile, after output color profile, or anywhere in-between,
  providing an important consistency improvement over HSL masking.

• A new color calibration module has been added as a full-featured hub for color correction.
  It was first intended as a scene-referred (unbounded) rewrite of the old channel mixer,
  allowing corrections of the color space, both for creative and corrective purposes.

  Because channel mixing is how white balancing and chromatic adaptation
  are implemented, color calibration also introduces robust chromatic adaptation transforms,
  Bradford (from ICC v4) and CAT16 (from CIECAM 2016), improving the color rendition
  of the white-balanced final image. The module provides a library of all standard
  CIE illuminants and two machine-learning illuminant detection algorithms, using
  different assumptions, for when no neutral colors can be sampled from the image,
  along with the traditional color-picker for manual sampling of neutral colors.

  Color calibration internally implements gamut-mapping and gamut-clipping,
  which attempts to preserve the hue and luminance of pixels while avoiding imaginary and
  out-of-gamut colors at the beginning of the pipeline, to improve the robustness of
  color-grading modules inside the pipeline. This is made necessary because
  white balancing will only push input out-of-gamut colors farther away,
  and will noticeably help dealing with artifical colored lights (LED, stage lighting, etc.).

  A new workflow setting "chromatic adaptation defaults", in processing preferences,
  allows users to choose to keep using the white balance module
  to perform the chromatic adaptation for new edits ("legacy" worflow, the default)
  or to use the new color calibration instead ("modern" workflow).
  The modern workflow still uses the usual white balance module, although
  with different default settings, because input color profiles and
  demosaicing need at least a rough white balancing early in the pipe.

• Map view has evolved. Images close to each other are now grouped and a count of
  grouped images is displayed on the bottom-left corner. This provides better performance
  when many images need to be shown on the map. Mouse-scrolling over a group's thumb scrolls through
  the images of the group. Groups containing selected images are highlighted with a white border.
  The image count is displayed as a white number if all images of the group are exactly at the
  same place, and in yellow otherwise.

  Movement of images within the map has also been improved. Click to drag the visible image,
  Shift-Click to drag the full group. A new "locations" module allows you to define location
  areas (using elliptical or rectangular shapes). These locations are saved as collections visible under "
  geotagging" in the collect module.

New Features And Changes

• Some parts of the GUI have been reworked in this version to complete
  the overhaul done in previous 3.2 release to ensure seamless
  integration (color, spacing). A good example is the combo-boxes.

• A focus-peaking button has been added in the lighttable and darkroom views which
  complements the existing keyboard shortcut. Focus-peaking helps to visualize the
  depth of field in an image by materializing the sharp edges.

• Better visual feedback is provided when changing module order with drag&drop.

• The wavelet algorithm has improved performance.

• A new tooltip has been added to items in the darkroom history stack module showing
  a list of the individual parameter changes at each step. This can
  especially help to track down unintended adjustments in modules with
  many tabs, such as filmic rgb or the parametric blending
  settings. This feature was based on the under-the-hood introspection
  enhancements delivered in 3.2.

• Processing modules now have a new tooltip, accessible by hovering over their header, containing
  a summary of what they do, how they work, in which color space they operate,
  if they expect linear, non-linear, display-referred, or scene-referred
  input and what kind of output they produce. This will help users to
  build consistent pipelines when reordering modules, by exposing the
  assumptions upon which each module is built, and provides an in-app
  documentation summary accessible offline.

• Processing modules have been updated with alias names and keyword lists which are used in the module group
  search. As a result, a module search can be performed using the exact names,
  synonyms (e.g. "dehaze" for "haze removal") or features. For example searching for "saturation"
  will return all modules that can perform saturation adjustments.

• Importing pictures from memory cards no longer uses the gPhoto API. This
  should now be more stable on Windows.

• Many changes have been made to modules to allow for narrower panels.

• The bilateral filter (used in local contrast, for example) has been enhanced for better performance.

• The reset button in the history module can now be used to delete the history stack.

• Ctrl+Clicking on the 'compress history stack' will truncate the history without compressing it.

• The export module has new options to specify the maximum output pixel dimensions using a
  scale factor or print size (cm or inch) and DPI.

• The Filmic RGB module has new graph views to help first time users.
  These views include a default base curve view in linear and logarithmic scales,
  consistent with the base curve module, and
  a zone-system view which shows the dynamic range mapping between scene
  and display grey scales. All the views have optional legends, which can be
  toggled on for new users, and off for experienced users seeking more
  GUI real-estate.

• Changing the pixel workflow preference (none, display-referred,

darktable 3.2.1 released

We're proud to announce the new feature release of darktable, 3.2.1!

The github release is here: https://github.com/darktable-org/darktable/releases/tag/release-3.2.1.

Because of last minute bugs that were found in the 3.2 release just after publication, we chose to immediately merge the fixes, and since the 3.2 version was already published, we increased the version number to 3.2.1. Therefore, the 3.2.1 release is the expected 3.2 (don't mind the version number).

As always, please don't use the autogenerated tarball provided by
github, but only our tar.xz. the checksums are:

When updating from the current stable 3.0.x series, please bear in
mind that your edits will be preserved during the upgrade, but the new
library and configuration files are not backward compatible; they're not usable with 3.0.x, so
making a backup is strongly advised.

Important note: to make sure that darktable can keep supporting the raw file format from 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!

The Big Ones

• The lighttable view has been rewritten and the filmstrip reworked, resulting in large performance gains, especially when using the zoomable lighttable view. The culling view has also been rewritten from scratch. Operations are smooth at any screen resolution up to 8k.

  Many types of overlay are now possible on lighttable thumbs. Different overlay
  information can be selected depending on the thumb size on the
  lighttable. The different sizes can be set in the preferences, so we
  can have no overlay at all for small thumbs and full overlay when
  large thumbs are displayed. This is fully configurable.

  Likewise, the tooltip information when hovering the thumbs can be
  activated/deactivated based on the thumbs size.

• The lighttable modules have improved user interaction: buttons are highlighted
  only when the context makes the action
  possible.

• A complete overhaul of the CSS has been done. This gives
  darktable a professional look. This continues
  the goal to make every single aspect of the UI themable using CSS.

• The Color Picker and
  Location modules are updated to better fit into the new UI, and most of the icons
  have been altered so as to be more visually balanced.

• The preference dialog has been fully reviewed and reorganized to
  propose a better look and require less
  scrolling. It is also possible to add some CSS rules directly into
  the preference dialog to tweak darktable's look as well as
  to directly control the font size and DPI values from the general
  preference tab.

  A search field has been added to the shortcuts tab to help you find
  the keyboard shortcut you want to customize.

• The new negadoctor module has been added to help inverting negative
  films.

• A new histogram display called RGB Parade has been added. At the
  same time the histogram module height can now be adjusted with
  Ctrl+Scroll.

• The metadata feature has been made generic internally and has new
  features. The user can now select the information they want to see in the
  metadata editor. This selection is automatically mirrored in the collection
  and image information modules.

  Along with a new "notes" field, all the fields are multiline
  Ctrl+Enter, sizable Ctrl+Scroll and can be set
  as private (not exported). Metadata collection filters have an entry
  "not defined". At import time it is possible to choose not to import
  some metadata.

• Image change detection has been made more reliable. This affects the
  lighttable thumbnails change symbol and history collection filter,
  which is now more accurate. In darkroom navigation, this avoids the
  need to recalculate an image and save the xmp file when there is no change.

• A new down-sampling preference has been introduced for faster
  response in darkroom. The preview is either computed at full
  resolution (original, default value) or at 1/2, 1/3 or 1/4 of the
  original size. This allow for better performance but can slightly
  hinder the precision of the guided filter masking.

  Note that this is a very delicate feature to implement. A lot of care has
  been taken to ensure all is correct when using down sampling. It
  touches all areas of darktable, like masks, guided filter, liquify
  controls, crop & rotate, lens and perspective corrections...

• Clarify the three possible workflows. Previous version had a preference
  to choose whether to auto-apply the base curve module. Many questions were
  raised about the intention. The new preference introduces three workflows:

  display-referred : use base-curve module

  scene-referred : use filmic and exposure modules (new default)

  none : use neither base-curve nor filmic

• Filmic RGB is updated to v4 (new color science) with integrated highlight recovery.

New Features And Changes

• Add support for curved gradients. This can be helpful when putting a gradient mask on an image with a horizon line that is curved due to lens distortion. This can also be for artistic goals.

• Add support for AVIF file format (requires libavif >= 0.7)

• Collect module has two new filters: module and module order.

  The former makes it possible to filter pictures based on the
  activated modules in the history. The latter can be used to filter
  based on the pipe version (legacy up to 2.6 releases or v3.0
  starting with 3.0 release).

• Tag in the Collect module keeps track of the selected images order.

  When a tag is at the first level of the Collect module, any change
  on the images order is kept along with the selected tag.
  This allows to the user to associate a specific order with every image (tag)
  collection.

• A full rewrite of the pipe ordering has been done. It is now
  possible to change the order of the pipe using a new module giving
  access to the legacy order (order used up to 2.6 releases) and the
  v3.0 order. It is also
  possible to create module order presets which can be freely applied.

  Note that the copy/paste of multi-instances when they have been
  reordered in a way that some other modules are separating them will
  not keep the same order. This was buggy in previous implementation
  when the target image had also been reordered in a non-compatible
  manner or using a different pipe order. In this new versions all the
  multi-instances will be grouped together keeping their relative
  order.

  Note that this work has mainly been done to make the implementation
  simpler, safer and that will require less maintenance. Also as this
  implementation records the full pipe order for history and styles it
  will be the ground for proposing different strategies when applying
  styles.

• The retouch module has a new keyboard shortcut "show or hide shapes" which can
  be mapped to a key to quickly show or hide shapes. This is in
  addition to the right-click on the image which does the same action.

• The spot removal module keyboard shortcut to show-hide shapes has been renamed
  to "show or hide shapes" for clarity and to be consistent with
  the new keyboard shortcut in the retouch module.

• It is possible to change the color of all overlays (shapes, guides,
  etc), in the darkroom. This may come handy on some images where the gray
  guides were barely visible. The possible colors are now: Grey,
  Red, Green, Yellow, Cyan, Magenta. The colors can be cycled through
  using Ctrl+O.

• In the crop & rotate module, the pan movements can be restricted
  vertically or horizontally using the Shift or
  Control respectively.

• The crop & rotate module now allows format ratios to be entered as
  a float number.

• When using a snapshot view, a flag has been added to clearly show the
  position of the snapshot.

• Improve the falloff and radius of the vignette to 200% for better
  control.

• Add a user-defined mode in the white-balance module to keep the last
  modification of the module. It is then possible to go back to the
  last modified setting after selecting another mode (spot for
  example).

• Dynamic keyboard shortcuts have been added for combo-boxes making it
  possible to select next and previous values directly from the
  keyboard.

• It is now possible to adjust the color picker areas just after
  having created them. This is achieved by dragging one of the four
  little square handles at the corner.

• Tagging improvements: Entry tag(s) creation works now without an image
  selected. It allows the user to create a tag on a virtual node, to insert
  a pipe | character in create tag (menu). The tree display
  shows the newly created tags.

• New variables $(LENS), $(EXIF_EXPOSURE_BIAS), $(VERSION_NAME) and
  $(VERSION_IF_MULTI) have been defined. $(CATEGORYn(category)) works
  now when multiple values on the same image (for example people) and
  accepts 9 levels instead of 3 (for n).

• Four new timestamps are now supported to store the import, last
  export, la...
