Camera Raw 6.4 - Downloads/Updates OK, Runs OK w/ PS CS5 Std

Question

Lightroom 3.4 and Camera Raw 6.4 now available
I never loaded the beta, so this is the first I've seen of this new update.
The software downloaded and installed itself perfectly using Help - Updates... from within Photoshop CS5 standard, and seems to work just fine. Nice job, Adobe!

Always isn't always prudent. The Release notes says it all:
Camera RAW 6.4 Release Notes
These items have been FIXED in 6.3:
Camera Raw did not allow      write-back capability for the EXIF GPS properties.
The DNG File format did not      support XMP Media Management.
A JPEG file with a specific      characteristic was found to have a pink cast.
The undo command (Command+z)      was failing to undo crop adjustments.
Single images marked for      deletion were not moved to the trash.
A magenta color cast could have      appeared on Nikon D7000 or Pentax K-5 images if the multi-exposure feature      was used with raw capture.
Applying Sigma 10-20mm Lens      Profile to Nikon D7000 raw files could have produced dark or black corners
Some EXIF fields of Panasonic      raw files appeared to be blank in Bridge Metadata panel
Applying the exposure      adjustment brush to a high ISO image  could have caused excessive noise      reduction correction to the  entire image
There are no 6.4 fixes posted.
So, is that a typo? Why would the fixes for 6.3 be re-posted?
In 6.3, I tested Command Z after cropping. It works. No weasel words here. Bullet 4 says "failing". So for the cropping undo, it looks like truth, not a typo.
This and the question about Nikon 18 to 105 lens gives me pause so far as upgrading.
