 #### Coordinate System Changes
 
-Coordinates are now represented using `Point` objects instead of arrays. This change affects methods that require coordinate input like cropping, drawing, and pixel manipulation.

 ### Masks

 The new `Mask` class uses 1 byte per pixel (vs 8 pixels per byte), trading ~8x memory usage for significantly faster bit operations and simpler data manipulation.
 
-### Points
+### Regions of Interest
+
+API for handling of regions of interest has also been changed.
+ROI creation methods like `fromMask()` and `fromWatershed()` are now standalone functions `fromMask()` and `watershed()`.
+
+```ts
+//Before
+import { Image } from 'image-js';
+
+const roiManager = mask.getRoiManager();
+roiManager.fromMask(mask);
+const rois = roiManager.getRois();
+```
+
+```ts
+//After
+import { Image, fromMask } from 'image-js';
+
+const roiManager = fromMask(mask);
+const rois = roiManager.getRois();
+```
+
+This simplifies the process of creating a map of regions of interest and eliminates the need for a separate initialization step, providing a more direct and functional approach to ROI creation.

 - `countAlphaPixel()` - Use custom pixel counting with `getPixel()`

+- `paintLabels()` and `roi.paint()` - Features were removed due to dependency issues. We plan to add it back in the future updates.
 - `warpingFourPoints()` - Use `getPerspectiveWarp()` + `transform()`.
 - 32-bit color depth has been currently removed. We plan to add it back in the future updates as well.
 - `CMYK` and `HSL` color models have been removed.
 - `insert()` has been removed.
 - `abs()` has been removed.
 - `paintMasks()` has been removed. Use `paintMask()`+ `for` loop.
-- `mergeRois()` has been removed.
 - `clearBit()` and `toggleBit()` have been removed, due to changes in `Mask`
   data representation (see ["Masks"](#masks)).
