This could be nifty.

On Friday, Adobe sent version 4.3 of its Lightroom image editing software out as a candidate release via its Adobe Labs web site.

The new version, a 410 megabyte download, offers the following fixes and changes:
- Full support for HiDPI displays such as Retina Display units.

- Unable to upload a large panorama to Adobe Revel via the Revel Publish Plugin.

- Unable to add a second photo to a page layout in a Book. This only occurred when the “Show Unused Photos” filter is selected in the filmstrip.

- A photo can be flagged as both a “Pick” and “Reject” at the same time when using the Toolbar to apply flags.

- Using multiple fonts within the same text cell inside a Book can sometimes cause Lightroom to crash.

- Exposure becomes the active adjustment slider in the Basic panel (within Develop) when moving from image to image.

- Customers using Photoshop Elements 11 were unable to upgrade their catalogs in Lightroom 4.

- Custom Cell padding options in the Book Module reset in between Lightroom sessions

- 1080p video files shot on iPhone 4S flicker on replay.

- Leaving the Book Module after using multiple text colors in the same text cell can sometimes cause the book to be lost.

The latest Photoshop Lightroom 4 also expands camera support to include the following:
- Canon PowerShot S110

- Canon PowerShot G15

- Canon PowerShot SX50 HS

- Casio Exilim EX-ZR1000

- Casio Exilim EX-FC300S

- Nikon D600 (expanded to full support)

- Olympus PEN E-PL5

- Olympus PEN E-PM2

- Olympus STYLUS XZ-2 iHS

- Panasonic DMC-GH3

- Pentax K-5 II

- Pentax K-5 IIs

- Pentax Q10

Adobe Photoshop Lightroom 4 was officially released earlier this year for OS X and PC. It’s available for purchase for US$149 for new customers, or US$79 for those upgrading from a previous version.
