1.19.3 is the most ideal version for the current minecraft. It has most mods, plugins, and excellent optimization. But here's the problem, not Arclight, not Mohist do not have a version for 1.19.3 (even on the official site). And how then to play with mods + plugins on 1.19.3? The transition to 1.19.4 affects most mods, because they simply do not exist on this version, and requests to the developers of these mods are useless.
I couldn't find a theme for cores, so I chose the theme of mods/modpacks. If there is one, move this topic to it.
