These Release Candidate updates, they are nifty…

Late Tuesday, Adobe offered a release candidate beta 4.4 of its Lightroom image editing program. The new version, a 441.4 megabyte download via MacUpdate, offers the following fixes and changes:

New Camera Support:
- Canon EOS 1D C

- Casio Exilim EX-ZR700

- Fujifilm X100s

- Fujifilm X20

- Hasselblad Lunar

- Leica M

- Nikon 1 V3

- Nikon 1 S1

- Pentax MX-1

Fixed Issues:
- 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.

Adobe Lightroom 4.4 retails for US$149.00 and requires an Intel-based Mac running Mac OS X 10.6 or later to install and run.
