According to the release notes, Lightroom 1.4 and Camera Raw 4.4 include corrections for the following issues:
* Previous camera profiles identified in the Calibrate panel of the Develop module may have displayed poor results at extreme ends of the temperature and tint ranges. A new camera profile identified as Camera Raw 4.4 is now available and will be applied by default to all images without existing Camera Raw or Lightroom settings. The creation of new default profiles will also include the updated Camera Raw 4.4 profile. Images edited in Camera Raw or Lightroom with earlier profiles will retain the earlier profile value and visual appearance.

* In previous grayscale conversions the Color Noise setting was disabled and this could result in an image with excessive noise when grayscale channel mixing is applied. Both the tool and effect have been enabled in Lightroom 1.4 and Camera Raw 4.4 providing the ability to reduce noise in grayscale conversions. In order to return to the prior visual appearance, Color Noise reduction can be set to zero.

Lightroom 1.4 includes corrections for the following issue:

* Compatibility with legacy printer drivers on OS X 10.5 (Leopard) has been updated.

Adobe has pulled version 1.4 of Lightroom temporarily.

..."According to Adobe Lightroom product manager Tom Hogarty, the updated releases both contain an EXIF time stamp error and a conversion error for Olympus JPEG files. The updates also cause a DNG conversion error, though that issue is limited specifically to the Windows releases"...
