GIMP extra color palettes

GIMP image editor 2.10.8 was released yesterday with rendering improvements, various bug-fixes and plugins ported to new iterator API in GEGL.

GIMP 2.10.8 announcement is not ready at the moment. Here’s the changes according to the NEWS file:

  • Use adaptive chunk size instead in GimpProjection when rendering the projection asynchronously, to provide a better trade-off between throughput and responsiveness dynamically, based on how fast the processing is.
  • In all selection tools, show error on attempt to subtract-from/intersect-with empty selection.
  • Fix text along path not working with vertical text.
  • Fix Text tool’s frame position when undoing a move operation.
  • Streamline Text tool’s drawing blocking/unblocking logic.
  • When moving a text layer using the text tool (through alt+drag), don’t change the layer’s box mode to “fixed”, which is unnecessary, since the layer’s size isn’t affected.
  • Transform and deformation operations now maintain color for fully transparent pixels, making unerase and curves manipulation of alpha channel more reliable.
  • All transform tools now apply changes when you save or export/overwrite an image without pressing Enter first to confirm changes.
  • Fix wrong application position when painting on a drawable whose origin is above/to the left of the image’s origin, and there’s a selection active.
  • Port all plug-ins to the new iterator API in GEGL.
  • Improve automatic detection of HEIC/HEIF files.
  • Improve RawTherapee discovery by looking up registry key
