With every new release of Minecraft all mods have to be updated or they will stop working of course. Since Minecraft 1.14.4 is still kinda new thing we've been getting a lot of questions if there are already 1.14.4 servers and mods.
The question requires two part answer, the good and the bad.
Now, the bad thing is many mods are in fact still not updated and as always some are abandoned. But there's really nothing we can do about that, Minecraft was like that since forever.
The good part your ask? Many mods are already updated and working on Minecraft 1.14.4, there's also working version of Forge for Minecraft 1.14.4.
Some of the mods include, Requiem Mod, Ceiling Torch Mod, Vanilla plus, Travel bag, XP-Plus mod, Tree chopper and many many other Minecraft 1.14.4 mods, be sure to check them out if you already updated your client.
