Krita 4.2 Released – Install Krita Image Editor on Linux Ubuntu

Krita 4.2 has been released. Install Krita image editor on Linux Ubuntu. Krita 4.2.0 is released with HDR Displays Support, new color gamut docker and an improved color palette docker. It also brings many architecture improvements and bug fixes.

Krita 4.2.0

1. HDR Display support – It’s now possible to view your HDR image in HDR, on supported hardware. You can now not only save your HDR image in .kra or OpenEXR files, but also extended PNG. With the right version of FFMPEG you can even create animations in HDR
2. Improved brush speed performance with vectorization and lock-free programming.
3. A new color gamut docker where you can limit your colors shown. New contributor Anna Medonosova has added this. This feature is available with the artistic color selector and the circle advanced color docker displays. Note: The default triangle selector doesn’t allow this feature.
4. More options and cleaned up Artistic Color Selector. There is now a “continuous mode” (infinity symbol) that allows you to remove the stepping with certain attributes. Additional options for new gamut masking. Anna Medonosova has added this great feature.
5. A news widget has been added to the startup screen that allows Krita to fetch the latest news coming from krita.org. Now, if there’s something interesting, like a new release, you’ll be in the front row! Clicking on a news item will take you to the web page.
6. Options to control how your backups are done. You can even control if you want your backup files to be stored in a different location. These settings are found in the “Configure Krita” main menu under the General section.
7. Improved Color Palette Docker. It is more stable as well as some of the following changes:
   * Instead of an entry-based docker, a rows and column based docker.
   * It can hold empty entries, which is useful for organizing.
   * Stable drag and dropping of colors.
   * Easy adding in entries by clicking them in the docker.
   * Right-clicking removes an entry.
   * Palettes can be put into the KRA file.
   * You can press the folder icon to open a palette editing dialog where you can set a palette to be stored in the document or resource-folder.
