Teased for months, Adobe is finally gearing up to launch full Retina support in Lightroom with today’s announcement of the Lightroom 4.3 Release Candidate, now available in Adobe Labs.

As Adobe explains, Lightroom users can now take advantage of HiDPI display support, like the one found in the Retina MacBook Pro, within the app’s Develop Module. In addition to this, Adobe’s Camera Raw 7.3 RC is also available, with both apps adding support for the following cameras:

Canon PowerShot S110, Canon PowerShot G15, Canon PowerShot SX50 HS, Casio Exilim EX-ZR1000, Casio Exilim EX-FC300S, Nikon D600, 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

Rounding out today’s news is a number of Lightroom bug fixes, which resolve the following issues:

  • 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.
