Apple has issued updates for MacBook, MacBook Pro, and MacBook Air notebook models to fix a rare battery issue. The updates are available via Apple's software updates page or through Software Update and the Mac App Store.
This update addresses a rare issue on some Apple notebooks where a battery that has accumulated more than 1000 charge cycles may unexpectedly shut down or stop functioning.
Update: MacRumors forum member Dempson looked inside the updates and found they are for the following machines:
MacBook
MacBook7,1 (13-inch, Mid 2010)

MacBook Air
MacBookAir3,1 (11-inch, Late 2010)
MacBookAir3,2 (13-inch, Late 2010)
MacBookAir4,1 (11-inch, Mid 2011)
MacBookAir4,2 (13-inch, Mid 2011)

My '11 MacBook Air froze on startup after the necessary restart. I did have the SuperDrive with a dvd inside plugged in, maybe that's why??

Not for Late 2012 MBP

Tried installing the downloaded package. It doesn't appear to be for a MacBookPro9,2.

It's only certain models apparently, but it doesn't state which. See here for MBP (here for everybody else).

If you don't get it in Software Update, you most likely don't need it. If you're skeptical, download it manually and see if your system takes it (it will tell you it's not meant for your system if it isn't).

Seems it isn't for 2011 MB's.

Looking inside the updates, they are for the following:

MacBook
MacBook7,1 (13-inch, Mid 2010)

MacBook Air
MacBookAir3,1 (11-inch, Late 2010)
MacBookAir3,2 (13-inch, Late 2010)
MacBookAir4,1 (11-inch, Mid 2011)
MacBookAir4,2 (13-inch, Mid 2011)

MacBook Pro
MacBookPro7,1 (13-inch, Mid 2010)
MacBookPro8,1 (13-inch, Early 2011 or Late 2011)

The MacBook disk image from the Apple support download page appears to be damaged - I got an error "There may be a problem with this disk image. Are you sure you want to open it?". I was able to examine the package after clicking the Open button, but it might be safer for MacBook users to get this one via Software Update until Apple fixes the image. The other two disk images mounted OK.

Edit: it occurs to me that the bad image might be a problem on my nearest Akamai mirror. Anyone else have problems mounting the MacBook disk image? (I downloaded it twice, didn't help.)

Since this update the fans on my air wont stop going up and down. All I'm doing is streaming a video that never used to make it go up and down before.
