Multiple Versions of fedora on boot

When booting my computer, the bootloader shows 4 entries (1 for Win8 and 3 for fedora).

When I installed Fedora, it showed 3 - one for windows, one for "Fedora" Linux and one for fedora with a version specified.

Since the install, there had been two system updates (maybe more); in which the "Fedora Linux" option was erased and two more version entries were added.

It is not a problem in any-way, but I would be happy to know the meaning of the duplicity (or, why should the system keep an option to boot an un-updated version).

By default, Fedora is set to keep the most recent three kernels, so that if the newest one fails to work properly you have (ideally) two known-good backups. Once you have those three Fedora entries in Grub, you'll see that every time the kernel is updated, not only do you get an entry for it, the oldest kernel is removed (as is its entry in the boot menu) to keep you with a total of three. It's possible to change this, but unless you have a very good reason, it's probably best to leave it alone and not worry about it.

Yes, that's what I meant. If you'll take a look at the menu, you'll see that each menu entry refers to a different kernel, and there might be one for a "rescue Linux" or something similar.
