We're proud to announce the bug-fix release of darktable, 5.4.1!

The github release is here: [https://github.com/darktable-org/darktable/releases/tag/release-5.4.1](https://github.com/darktable-org/darktable/releases/tag/release-5.4.1).

To build from source, do not use the autogenerated tarball provided by GitHub on the release page, download our tar.xz file instead. If you're just building for yourself without creating a package for some distribution, then using source code cloning in git is an even more convenient way.

The checksums are:

```
$ sha256sum darktable-5.4.1.tar.xz
???  darktable-5.4.1.tar.xz

$ sha256sum darktable-5.4.1-arm64.dmg
???  darktable-5.4.1-arm64.dmg

$ sha256sum darktable-5.4.1-x86_64.dmg
???  darktable-5.4.1-x86_64.dmg

$ sha256sum darktable-5.4.1-win64.exe
???  darktable-5.4.1-win64.exe

$ sha256sum Darktable-5.4.1-x86_64.AppImage
???  Darktable-5.4.1-x86_64.AppImage
```

When updating from the stable 5.2 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 5.2.

You are strongly advised to take a backup first.

## Bug Fixes

- Fixed wrong handling of scaling factor during multi-preset export.

- Fixed missing help URL, pointing to the online documentation, for
  the new AgX module.

- Fixed wrong handling of overwrite if changed in export.

- Fixed images exported with wrong settings when using multi-preset
  export.

- Fixed wrong RAW specific auto-applied preset being applied to non
  RAW images.

- Fixed subtle color casts in bayer dual demosaicers.

- RustiCL gets the default optimizing compiler flags as other
  platforms.

- Fixed loading some Olympus ORF files (e.g. E-410 and E-510)
  due to a possible crash or memory corruption when parsing
  highlight-preservation Exif tag.

- Fixed the mask support in scale pixels module.

- Fixed a possible crash when using workspace due to the non
  deterministic ordering of the list of workspace read on disk.

- The list of the allowed tags in the metadata editor preferences has
  been restricted to tags which are supposed to be user-editable.

- Fixed the thumbnail information update in the overlay or the tooltip
  when some metadata variable are used. That is, when changing the
  metadata we need to recompute the thumbnail information.

- Fixed a possibly standstill while discarding history on fast
  systems.

- Fixed a possible crash in the way the Color Equalizer module GUI is
  initialized.

- Fixed an issue in culling layout where switching to the darkroom
  sometimes failed with an error message.

- Fixed an inconsistency in the styles module UI when shown in the
  darkroom view. It is not possible to create a duplicate to which the
  style is applied, and the setting of the corresponding checkbox has
  just been ignored. To avoid confusion, the checkbox is now hidden in
  the darkroom view.

- Fixes resets to default OpenCL per device setting.

- Fixed possibly outdated metadata when returning from darkroom. For
  example if the image is cropped in darkroom, the metadata $(WIDTH.x)
  and $(HEIGHT.x) where not correct on lighttable.

- Fixed a missing thumbnail overlays with $(CATEGORY[n,m]) variables
  update when a tag is assigned.

- Fixed jumping of curvature slider when used on the mask manager.

- Fixed a crash when mounting a camera from Darktable due to the
  current locale. Mounting is now done using the C locale.
