3 upgrades to the same kernel in a month? [3.13.0-46 on kubuntu 14.04, 64bit]

[aria]

Hi,

What happens with this kernel: 3.13.0-46 (kubuntu 14.04, 64bit)?
In last 10 days or so, did upgrade 3 times to the... same kernel: 3.13.0-46.
And at least 2 times there were 50MB&+ of kernel files to download! I was used with KB, not MB when kernels upgraded.
And same things happened on both laptops I have kubuntu 14.04 on, laptops used by different persons, so I would exclude a contamination with don't know what. And besides, both systems work like a charm.

Has anybody an idea of what happens? Did anybody else experienced the same thing? At least, is it benignant?
Thanks,

[Snowhog]

The kernel upgrades were 'minor' sub-point changes. Note that they were -46.75, -46.76, and -46.77.

I see it just now: 3.13.0-46.75, Friday ...46.75 & ...46.76, and today only ...46.76.
I see but don't understand a thing. What does all this mean?
Why do appear two kernel variants (...46.75 & ...46.76) in the Friday update? In the same update!
But now, with this small difference (75 to 76) I start to believe it is benignant.

Thanks Snowhog, just added my post while you was adding yours. So, all should be fine.
Bests,

They aren't kernel variants. They are in fact kernel upgrades; minor upgrades, but upgrades none the less.
