'Pokémon Go' Update Notes: 0.43.3/1.13.3 changes the way you hatch Pokémon eggs
Why you'll want to download it: If you'd rather hatch Snorlaxes than Pidgeys from your eggs in Pokémon Go, developer Niantic is updating the way egg-hatching works, making it easier to find the eggs you want to hatch first.
New egg colors in Pokémon Go means easier egg sifting
Pokémon eggs are hatched by putting the eggs into an incubator and then walking a set distance based on the type of egg you're incubating. Eggs can require 2, 5 or 10 kilometers of walking before they hatch.
The screenshot of the update provided by Niantic along with the patch notes illustrates that 2-kilometer eggs will remain green, the default egg color prior to the update, while 5-kilometer eggs will be displayed in orange and 10-kilometer eggs will become purple.
The patch notes also state that each Pokémon's information screen will bear an icon denoting its type once the patch is downloaded. Also included in the patch are a low-battery indicator for the Pokémon Go Plus device and minor text fixes.
