Recently i updated my wordpress to its latest version 3.4.1 and noticed that few of my plugins are only compatible upto 3.3 although they are working correctly for my site even with the latest version.

So does that means that i need to disable those plugins and look for the alternatives and these plugins are no more SAFE to use or it is something else( i downloaded all plugins from wordpress.org ONLY) .

Need a better clarification over this and let me know if some concept i m missing with the up gradation :) . Detailed answer is really appreciated and i will do my part then :)

Normally, I'm more worried with plugins that show, say, 3.1 compatibility... Those I test, as toscho points out, more thoroughly. – brasofilo Jul 5 '12 at 11:41

The compatibility shows just the latest version the plugin was tested on. If WordPress didn’t change the API the plugin will continue working and you don’t have to worry.

Test it. There is no other way to be sure.

so is thr any plugin that can check vulnerability in plugin files?? – swapnesh Jul 5 '12 at 11:41
That’s a different question. In short: no, not really. There are unlimited ways how a plugin can be vulnerable, impossible to test that automatically. There are plugins claiming to find security holes. They are (in my opinion) snake oil. – toscho Jul 5 '12 at 11:45
