A Plugin to Update Plugins?

Such things have been made before, but they don’t tend to last particularly long because we don’t have a central repository for plugins yet.

Otto42 is right, as of now there’s no plugin to get updates from different places.

I’m using a plugin that checks and notify updates from repository. Check this post.

Update manager is the plugin he mentions on that page.
Now you can just click through to what you wanted ??
