Do mods still work in 1.4? Are they worth using?

[DaniCrypt]

I'm wondering if its worth using mods with the new update? I spent many hours figuring which of mine work and don't cause the game to... be super laggy >_<...

Opinions? What mods work for you guys?

I'm a little sad... the map I made does not work with the update... -sighs-

Many mods have already been updated to work with the new update. You can check https://mods.smapi.io to see if the SMAPI mod you're asking about has been updated or if it's broken, it may have an unofficial update (Depending on if it's open sourced or not).
