How to update my addon ?

[Kimundi]

Hello everybody !

I have some addon out of date, but when I looked for an updated version on Curse-gaming, they are already out of date. They work, but each I started playing, I have an error message : "Your addons are out of date and it may slow your game, click here to disable your addons".

I have heard somewhere that a little freeware can update all my addon, but I can't find it anymore...
