Lightroom4.2 RC 出來了，我一直都覺得4.1 好有問題，4.2 快點來吧！！！
The following issues have been fixed in Lightroom 4.2 release candidate:
- Folder stacks with virtual copies get unstacked when moving to another folder.
- Stacked photos get hidden in both the Grid view and Filmstrip. This occurs when photos get unstacked as a result of enabling auto-stacking.
- Errors encountered when publishing videos to Facebook through the Facebook Publish Service.
- Users may have occurred problems when trying to enter the Web Module from Library.
- Unable to edit JPEG photos in Photoshop Elements.
- Unable to upload files to Flickr if there is a carriage return in either the Title or Caption fields (Win only).
- Background graphics that are applied to a Book globally may not appear as expected in a Saved PDF.
- Certain book covers had spine text positioned in a Horizontal manner, not Vertical.
- Double byte characters are not being exported to PDF in Books.
- Photos were exported with original GPS coordinates recorded by the camera, not with the GPS coordinates updated in Lightroom.
- Keyboard shortcuts in the Develop module sometimes do not work when editing an image in Process Version PV2010.
- Parents and synonyms of “do not export" keywords also do not export.
- Audio does not play in video files after creating a slideshow containing music (win7 only).
- Tether support not working for Nikon D4, D800 , and D800E (win only).
Can Lightroom 4.2 Release Candidate be installed alongside Lightroom 4.1?
- Mac: The Lightroom 4.2 release candidate for Mac can be installed alongside earlier versions of Lightroom 4.
- Windows: By default, the Lightroom 4.2 release candidate for Windows will remove or overwrite your existing Lightroom 4 installation. If you wish to return to Lightroom 4 after installing Lightroom 4.2, simply reinstall Lightroom 4 from your original download after uninstalling Lightroom 4.2 using the Windows add/remove program utility.
Both versions of the application share the same catalog format allowing your catalogs to be opened by either version without complications.
