After 24 days with no news, Niantic have just announced a Pokémon GO update (0.53.1 for Android and 1.23.1 for iOS).

Updated Apple Watch to display Eggs obtained from PokéStops

Changed distance tracking to better account for GPS drift

Minor text fixes.

The Apple Watch's screen will now be able to display eggs that are obtained from PokéStops.

Fixing the GPS drift sounds like it stops you accumulating distance travelled when you're not moving - bad luck for those used to hatching eggs while sitting at your desk. Realistically, anyone playing the game properly shouldn't miss those rare 0.1km distances!

New Pokémon genders

There are now in-game differences in the male and female Pikachu and Raichu models:

The female Pikachu's tail ends in a heart shape

The female Raichu's tail is blunt at the end

Hidden updates

Additionally, there are some undocumented changes in the update discovered by TheSilphRoad which makes the patch far more exciting, including:

38 new moves have been added to the game

These moves (more than likely for Gen 2 Pokémon) are now in the game, and are ready to be activated server-side.
