What IOS version should I have?

I have a 2621 router running IOS version 12.0(7)T. Can someone tell me where I can go to get the latest stable version and what version I should be running?

Thanks in advance.

Re: What IOS version should I have?

Here is a great place to start:

Are you experiencing some specific issue or need some new feature? If so, you will want to ensure the release you go to incorporates the necessary fixes/features.

Here are many useful links you should research in making your decision:

I would recommend doing your own research since you know exactly what your network needs. Upgrading to the latest and greatest isn't always the right thing to do for your network.

Thanks for the info, I will indeed use these resources. However I was specifically concerned over a security patch that was announced a couple of months ago. I believe it would open a router up to DOS attacks. Do you know what that specific patch was or a pointer to resources for that?
