See this about MC 1.20.5 and later versions

https://old.reddit.com/r/litematica/comments/1di4o3h/announcement_about_litematicas_future_and_updates/

TL;DR; I won't maintain the 1.20.5+ versions myself anymore, at least for now. There are ports by Sakura-Ryoko. They will be here once they are more stable, see the post for the links and details before then.

Description

MaLiLib is a library mod containing shared code for masa's client-side mods.
Basically it contains all the configuration options, keybind stuff, most of the GUI code and a bunch of other utility stuff for the mods that use it.
(The name is just short for masa's Litemod Library, because I have zero imagination... [since it was first created for the LiteLoader versions of the mods])

Make sure to get the correct mod version from the Files page!!
Note: There are both Fabric and Forge versions for 1.14.4 and later MC versions, look at the file name to get the correct version!

The file name always indicates the mod loader (for example Fabric vs. Forge) and the Minecraft version:
malilib-<mod loader>-<MC version>-<mod version>.jar

For example:
malilib-fabric-1.15.2-0.10.0-dev.20+arne.6.jar

Malilib is required by the following mods, starting from the indicated versions:

• Item Scroller - 0.14.0 and later
• Litematica - for any builds starting from around 2018-06-11
• MiniHUD - 0.17.0 and later
• TellMe - 0.6.1 and later
• Tweakeroo - 0.8.0 and later

The exact required version of malilib for each mod version will be indicated in the changelog of each of the dependent mods.

Basically when some mod requires a newer version of malilib, then all the other dependent mods will also get an update at the same time, if the change in malilib breaks compatibility. Normally breaking changes should hopefully be rare.

Basically you should be able to always use the latest version of malilib for any of the dependent mods, at least if you update them all at the same time, as you always should.
TL;DR; Update everything at once!

Starting from the 0.10.0-dev.19 version of malilib, the only required part of Fabric API is embedded inside malilib, so you don't need to get the Fabric API mod separately anymore just for my mods.

For MC 1.13.x you should note that only 1.13.2 is supported, so you need Rift for 1.13.2 from Chocohead's fork.

Rift 1.13.2 installation (if you play Minecraft 1.13.2):

Description

MaLiLib is a library mod for client-side mods, containing most of the shared code between the dependent mods. For example it contains all the configuration options and serialization, a powerful keybind system, most of the Screen/GUI code and a bunch of other miscellaneous utility classes and methods for the mods that are built around MaLiLib.

(The name is short for masa's Litemod Library because I have zero imagination... The mod was initially created for the 1.12.x LiteLoader versions of masa's client mods.)

Mods that require MaLiLib

MaLiLib is required by all of masa's client-side mods, starting from the indicated versions:

• Item Scroller - 0.14.0 and later
• Litematica - for any builds starting from around 2018-06-11
• MiniHUD - 0.17.0 and later
• TellMe - 0.6.1 and later
• Tweakeroo - 0.8.0 and later

There are also a number of other client-side mods by other authors that are built around MaLiLib. The mod project/description usually indicates which mod(s) are required as a dependency.

Mod Versions

Make sure to download the correct mod version for your Minecraft version and mod loader from the Versions page!!

Note: There are both Fabric and Forge versions of the mod! Look at the tagged mod loader or the file name to get the correct version of the mod for your mod loader!

The file name always indicates the mod loader (for example Fabric vs. Forge) and the Minecraft version. The file name is in the format: malilib-<mod loader>-<MC version>-<mod version>.jar

For example: malilib-fabric-1.19.2-0.13.0.jar

The required version of malilib for each mod version may be indicated in the changelog of each of the dependent mods. But basically you want to get the version of all the mods that were the latest released version at the given time, to avoid version mismatches.

This would mostly become more tricky to figure out if you for some reason want to use certain older mod versions than the latest available version for a given MC version. Especially the 0.9.x and 0.10.x version era of MaLiLib for MC 1.12.2 and 1.14.x and 1.15.x (and maybe also 1.16.x still?) were kinda volatile for version compatibility. Also the releases based on the code rewrites, starting from MaLiLib 0.50.0 and going until the eventual 1.0.0 release change lots of things between versions, so getting all the mods from the same release date is crucial.
