This release also fixes the following bugs:

Web galleries with a Collection Title of six characters would not export or upload
The crop aspect ratio could revert to the last selected ratio even when reset to original
The crop aspect ratio in Quick Develop could be lost after a crop adjustment
The crop aspect ratio lock could be lost after an orientation switch
Images could preview incorrectly when imported using the MTP/PTP USB protocol
Sony .ARW files may not have been recognized by Lightroom’s import dialog
The Japanese language configuration of Lightroom on Mac OS X 10.5 could fail to switch to the print module if the HP B9180 was set as the default printer
Metadata options that are intended for use were dimmed incorrectly when exporting DNG files
The Japanese language configuration of Lightroom on Mac OS X was missing a shortcut for “Zoom Out”
Several translation and shortcut corrections were made for the eight additional languages introduced with Lightroom 2.3

Camera Raw 5.4 is also available (WIN | Mac). This is needed for Edit in Photoshop commands, to allow a file to open without creating an intermediate file. The DNG spec is also updated to 1.3.
