Version 3.1 - 19 June 2023:
- Added a new "Generate" sampling mode that lets you generate a range of colors without sampling from an image or screen. Colors can be generated by varying the red/gree/blue channels, or the hue/saturation/brightness/value, or the temperature/luminance. Colors can be varied by using a ramp, noise or by random selection. It can also generate analogous, complementary, triadic and tetradic colors.
Version 3.0 - 23 May 2023:
- When "Inspect Pixels" is enabled under "Draw on Screen", zoomed-in pixels are now shown next to the cursor in addition to the color values. Also added "Info Scale" to scale the size of the pixel info.
- Added the "CIEDE2000" difference method under "Color Difference" and added "Max Color Difference".
Version 2.9 - 27 October 2021:
- A screenshot of the currently selected screen can now be displayed in the viewport.

- Added "Alignment" that sets the alignment of the swatches, and "First Color Location" that sets which corner of the viewport swatches that should contain the first color: "Top Left", "Top Right", "Bottom Right", "Bottom Left", under "Sampling" > "Viewport" > "Swatches".
- Added "Clamp", "Hue/Saturation/Value/Brightness Range" and "Remove Colors Outside Hue/Saturation/Value/Brightness Range" under each color override.
- Added "Brightness" under "Sampling" > "Viewport" > "Image".
- Added "Display Cluster Color in Viewport" under "Sampling" > "Most Frequent Colors".
Version 2.8 - 29 September 2021:

- Added an "Image Mode" parameter under "Export Colors" that sets wether the colors should be exported as the swatches shown in the viewport or as they are shown in the color ramp.
- Added an "Input" tab under "Sampling" with the parameter "Keep Existing Colors" to allow using existing point colors instead of sampling from an image or a screen.
- Renamed some parameters.

- Renamed the "Screen" section to "Draw on Screen".
- Added "Output Settings" under "Sampling" with settings related to the second output pin of the node. "Set Max Number of Samples", "Max Number of Samples" and "Start Sample Nr" limits how many sample points are output from the second node pin. "Affect Number of Stored Colors" will affect the number of colors stored in the ramp and "Affect Number of Displayed Samples" affects the number of samples displayed in the viewport.
- Added "Snap Points to Pixels".
- Added "Image Filter" under "Viewport Settings".
- Added "Export Color Float Values", "Export Color Integer Values", "Export Color Hex Values" and "Export Color IDs" under "Colors" > "Export Colors".

- Fixed an issue where sometimes the image would display flipped and with the wrong size in the viewport.
- Renamed some parameters.
- Moved the asset from the "Digital Assets" menu to "Techie's Digital Assets".
Version 2.4 - 19 August 2021:
- Re-designed the "Line Sampling" section. It's now possible to set individual parameters for each line. Line positions can be set using local space coordinates or pixel coordinates which allows for exact positioning of the sample points. Positions and rotations can be randomized and lines can be extended to the image bounds.
- Improved the performance of "Sample Pixels Between Points".
- Added parameters for exporting the colors to a JSON text file.
- Added "Pixels per Color" under "Export Colors". This overrides the width of the exported image.

- Added "Fuse Overlapping Samples".
- Added "Image Transparency".
- Moved "Sample Every Nth Pixel" to the "Grid Sampling" section and removed the "Pixel Sampling" section.
