The removal of trading means many classic Pokémon have new evolution triggers. The documentation reveals the following updated methods: Level-Up Evolutions Levels up at Level 40. Machoke to Machamp: Levels up at Level 40. Graveler to Golem: Levels up at Level 40. Haunter to Gengar: Levels up at Level 40.
Notably, an unofficial by a user named mikelan98 (also known as MeroMero) introduced Fairy typing and Fairy‑type moves to the game, as well as updated Pokémon typings (such as making Wigglytuff, Clefable, and Gardevoir part Fairy‑type). This unofficial version has its own documentation additions, which you can find linked in the GBAtemp thread.
