Canary for Minecraft Forge
Canary is a general optimization mod and unofficial fork of Lithium mod for Minecraft Forge. It works on both the client and server, and can be installed on servers without requiring clients to also have the mod.
Canary contains the original Lithium optimizations(mob Ai, chunk loading, game physics, etc..) and also, Canary contains new optimizations to make the gameplay smoother, without changing any behavior.
Configuration
Canary makes use of an unusual configuration system which can be used to enable or disable certain patches. For more information, please read the wiki entry.
Modpack Permissions
Of Course, You can include it in your modpack.
Issues and Feature Requests
Please use the issue tracker linked at the bottom of the page to report bugs, crashes, and if you want to propose new features or otherwise contribute to the mod, i will gladly accept pull requests, as well!
