Hello Aternos Team,
There is a new update here on the main site for Pixelmon Generations.
This is to just show you the update, this is not the modpack.
Aternos only has the version 2.3.0 so far, and I would like to play with my friends on the newest update, and many users who'd want to do the same would most likely appreciate it.
Keep up the great work guys!

You can also find this modpack here on the Technic Pack site.
