The default download is for Fabric. To download the Forge version, go to the files tab!

 

A couple of days ago, something changed in Mojang's blocked users API, causing the client to

not properly load the list of blocked users on start. Because of this, the client will attempt to

fetch the blocklist every two minutes when the chat is being rendered. This loading is done on

the same thread as the rendering, causing the game to freeze until Mojang's API returns a response.

Since the requests takes a while to complete, this will cause a noticeable lag spike.

This issue is being tracked in Mojira issue WEB-5587.
