kernel upgrade with yum removed old kernels

[Martin Marques <martin@xxxxxxxxxxxxxxx>]

I just finished upgrading the kernels in my FC6 with yum and I see this 
at the end:

Removed: kernel.i686 0:2.6.20-1.2933.fc6 kernel.i686 0:2.6.18-1.2798.fc6
Installed: kernel.i686 0:2.6.20-1.2948.fc6

Now, why did it remove does kernel? Shouldn't it just install the new 
ones and leave old ones there?
