What’s new in Boot Camp 3.2?

Boot Camp 3.2 is out. It is not a cumulative update. You have to install Boot Camp 3.0 from Snow Leopard, then apply 3.1 and then apply 3.2. Apple says that it “adds support for the ATI-Radeon HD 5870 graphics card, Apple USB Ethernet Adapter, MacBook Air SuperDrive, and addresses critical bug fixes.”

Apple doesn’t describe what the critical bug fixes are, but here’s what else is new in there.

• New Apple mutlitouch touchpad drivers: 3.1.0.10 (replaces 3.0.0.0)
• New Cirrus Audio drivers: 6.6006.1.26 (replaces previous patch 6.6001.1.25 from BC 3.1.3 or  6.60001.1.21 from BC 3.1).
• New Apple wireless touchpad drivers: 3.1.0.7
• New Boot Camp manager (bootcamp.exe): 3.1.0.10 (replaces 3.0.0.1)
• New Boot Camp control panel AppleControlPanel.exe: 3.2.0.0 (replaces 3.0.0.2)
• New Apple OS Manager: 3.1.0.3 (replaces 3.1.0.1)
• New HFS+ driver, AppleHFS.sys: 3.2.0.0 (replaces 3.1.0.0)
• New apple mount manager, AppleMNT.sys: 3.2.0.0 (replaces 3.0.0.1.8)

The most immediate thing that I noticed is that FN+F5 on my MacBook Pro (MacBookPro5,3) can now dial the keyboard backlight all the way down to off. The built-in speaker volume also seems to be much louder without any enhancements enabled.

Maybe with Boot Camp 3.0 (Lion?) we’ll get an ambient light sensor driver so that the Adaptive Brightness service in Windows 7 can work.
