Adobe has announced 'release candidate' versions of Lightroom 4.4 and
Adobe Camera Raw 7.4. As usual, the latest near-complete versions add
support for recent cameras. What makes this release especially
significant, however, is improved support for Fujifilm's X-Trans sensor
models, including the X-Pro1 and X-E1. The Lightroom update also
corrects a series of bugs present in the current version of the
software. As usual, release candidates are considered well tested but
not final.
New Camera Support in the Camera Raw 7.4 and Lightroom 4.4 Release Candidates
- Canon EOS-1D C
- Casio Exilim EX-ZR700
- Fujifilm X100S
- Fujifilm X20
- Pentax MX1
- Nikon 1 J3
- Nikon 1 S1
- Hasselblad Lunar
- Leica M
Fixed issues in Lightroom 4.4
The following issues have been fixed in Lightroom 4.4 release candidate:
- The crop overlay tool resized incorrectly when used in conjunction with the “Constrain to Crop” checkbox in the Lens Correction panel
- Background graphics were not correctly rendered within the Book Module
- The supplied lens profile for the Sony RX-1 did not contain vignette information
- Previews of photos in portrait orientation were blurry when viewed in the filmstrip in the Develop module. (Mac only)
- Stack badges displayed the wrong count when creating new stack that included a preexisting stack.
- The Filter scrollbar within the Library module was not rendering properly.
Judging from what is said (and from a small test), it seems that LR4.4 and ACR 7.4 have some pros and cons comparing to their previous version. More aggressive sharpening is needed to match their settings, but the new versions render colors in a more accurate way.
