New Things
Nodes:
Color Ramp Node - generate smooth color gradients directly in the node graph

Vector Math Node - for more advanced procedural workflows
Sticky Note Node - leave notes on your canvas (available in 16,581,375 colors!)

Comment Node - create custom colored zones with a comment text

Color Mapping Node + new palette input type
Random Node for procedural variation
Palette and Decompose Palette Nodes
Normalize Color Values option added to Separate and Combine Color Nodes
More sample texture options in the Stroke Info Node, plus a new Stamp property
Tools:
Find and Replace, Swap Color and Background Eraser tools added to the Adjustments toolset
Gradient Brush added to Brush Picker
Reset symmetry line buttons
Improvements
Selecting multiple vector layers and changing the main color now recolors all of them at once
Brush Engine optimizations for smoother performance
Velocity interpolation added for faster, cleaner strokes
Gradient tool performance optimized
More blend modes added to the Merge Node
Node Graph colors now use a 0–1 range instead of 0–255
Improved localization debug window
100% Spanish localization completed!
Fixes
Fixed layer move issues when a non-structure layer was in between

Fixed array-of-arrays creation bug
Fixed auto-saves writing to the temp folder instead of local app data
Debug recording graph snapshots now save to the temp folder instead of the working directory
Fixed folder deletion not removing nested folders
