About Moderner Beta
From ModrinthOld (and not so old) world generation for modern Minecraft!
<!-- This is horribly obsolete HTML. I can't do anything about it. -->
Welcome to Moderner Beta! This is a fork of b3spectacled's Modern Beta that started out as a pull request but due to the original creator's inactivity has been published as a fork. Alongside all of the world generation options from Modern Beta, this fork adds in world generators from Beta 1.8 all the way up to Release 1.17 which are highly customisable with plenty of configuration options. The goal of this fork now is to pick Modern Beta's development back up and add in extra features.
Notice
Moderner Beta 5.0.0 is currently in alpha. There may be bugs and issues, and can be prone to breaking with future releases. 4.1.x will continue to be supported until 5.0.0 exits development. Development may take quite some time. If you could help, then please consider applying as a developer here.

Additional add-ons
For the authentic early release look, use a resource pack like PACP to add the programmer art style to newer content and use Sodium Extra to thicken the fog by turning down the fog start multiplier to 25% (or 75% if a 1.7-1.17 look is desired).
For a beta-style look, use a resource pack like Golden Days and use Nostalgic Tweaks to further restore old mechanics and visuals.
