List of game updates

Pokémon GO is in constant development since its official launch and has received multiple updates, that are listed below. There are two sorts of updates the game gets:
 * Game client updates
 * Server-sided updates

List of client updates
Public client updates can be downloaded from Play Store, App Store or APKMirror in order to have game up to date.

The game have been updated also in its closed beta testing phase in spring 2016.

Server-sided updates
Server-sided updates can be released at any time and player does not have to download them manually and they do not require an update on the app client. They also affect all players at the same time. They are harder to track than game client updates and it is nearly impossible to list them all, as most of them is not publicly logged nor announced by game creators. However, following changes to the game are caused by server-sided updates:
 * changes to spawnrate of Pokémon in the wild and their shiny variant encounter rate, mostly during particular events,
 * changes to Pokémon sprite assets and their model textures,
 * releases of new Pokémon species and forms which data is previously implemented to game client,
 * changes to pool of Egg hatchlings,
 * changes to pool of Raid Bosses,
 * changes to Research tasks, their rewards and Research Breakthrough,
 * releases of new Special Research series which data is previously implemented to game client,
 * releases of new avatar items,
 * changes to Pokémon learnsets and specific attacks (including changes of their power and energy),
 * in-game shop special offers and promotions,
 * GO Battle League rewards and ranks features,
 * most of event features in general (including multiplied or bonus amounts of rewarded XP, Stardust and Candy; shortened distances for Buddy Pokémon and incubated Eggs).
