 ### Changed
 
 * NODATA and TRANSPARENT values are merged. [[#41](https://github.com/nasa/harmony-browse-image-generator/pull/41)]
-  - The user visible change is that now a paletted output PNG will have up to 254 color values and a 255th value that is transparent.
-  - Internally, the code change removes `TRANSPARENT_IDX` (254) and uses `NODATA_IDX` in its stead.  A color of (0,0,0,0) was already set to both of the indexes in the ouput PNGs. This ensures the roundtrip from single band to RGBA to Paletted PNG is consistent.

 ### Changed
 
-* Input GeoTIFF RGB[A] images are **no longer palettized** when converted to a PNG. The new resulting output browse images are now 3 or 4 band PNG retaining the color information of the input image.[#39](https://github.com/nasa/harmony-browse-image-generator/pull/39)
-* Changed pre-commit configuration to remove `black-jupyter` dependency [#38](https://github.com/nasa/harmony-browse-image-generator/pull/38)
-* Updates service image's python to 3.12 [#38](https://github.com/nasa/harmony-browse-image-generator/pull/38)
-* Simplifies test scripts to run with pytest and pytest plugins [#38](https://github.com/nasa/harmony-browse-image-generator/pull/38)
