Hydrogen 0.3.1 for Minecraft 1.17.1

This is a minor version bump to Minecraft 1.17.1 and includes only a small internal improvement for classloading.

Hydrogen 0.3 for Minecraft 1.17

This release is a mostly straightforward port to Minecraft 1.17 with an additional optimization for de-duplicating identifiers, saving a small amount of memory (~5 MiB) in vanilla, and possibly more in heavily modded scenarios.

Hydrogen 0.2.0 for Minecraft 1.16.5

This is the first "probably stable enough to throw into your game" release. A number of mod compatibility issues have been fixed, most of which stemmed from the mod using reference equality on block properties.

Hydrogen 0.1.1 for Minecraft 1.16.2

This is the first "formal" release of my new mod, Hydrogen. It works on either the client or server and isn't required on the connecting side. The primary goal with this mod is to reduce the game's memory usage as much as possible with some more aggressive optimization techniques, things of which normally would not be considered in my other mod, Lithium. However, it also doesn't change any game behaviors, making it fully transparent.

In layman's terms, this means that your game requires less memory to run, and that it'll be a little bit faster (maybe.) We've seen a 25-35% improvement to the game's base memory utilization in a variety of Fabric modpacks. As for players without many content mods, the effects will be much less significant, but non-zero.

⚠️ Hydrogen hasn't received a super extensive amount of testing, but preliminary reports would suggest things are fairly stable. That isn't a warranty however, and you should make backups of your worlds before installing it.

You can download the mod by clicking here or by using one of the files below (you want the file with no suffix.)

I won't be releasing this on CurseForge until we get some better numbers on how this reduces memory usage and confirmation that it isn't broken. If you want to help, consider joining my Discord server.
