GIMP image editor released new development version 2.99.8 for the next 3.0 series with some great new features.

GIMP 2.99.8 introduced multiple layers support for its Clone, Heal and Perspective Clone tools. There are as well 2 new modes in particular:

When sourcing from multiple selected drawables then cloning into a single drawable, the pixel source is the composited render of source layers.
When cloning while multiple drawables are selected, each drawable clones from itself to itself, i.e. every drawable is both its source and target.

The release added support for loading and exporting JPEG-XL (.jxl) files via the libjxl library. And it supports larger-than-4GiB PSD files and loading up to 99 channels, as well as PSB files with width and height up to 300,000 pixels.

Thanks to Windows Ink support, GIMP now has more more graphics tablets or touch input devices support. Other changes in GIMP 2.99.8 include:

  • Selection cue fixed on Wayland and macOS
  • Clicking anywhere on the toolbox or on Wilber’s drop area now returns the focus to the canvas
  • Dropped the thumbnail icon feature.
  • Memory leak fixes and plug-in improvements.
