Actually LR is in Release Candidate now -- works fine. The memory leak in 2.2 has also been fixed.
These bugs fixed
- In the Windows 64-bit version of Lightroom an sFTP upload process could cause Lightroom to crash.
- Slideshows could return to the first image randomly during playback.
- A memory leak could cause Lightroom to crash while attempting to process files with local adjustments.
- Canon EOS 5D Mk II sRAW files could process with artifacts in Lightroom 2.2.
- Lightroom 2.2 could cause disc burning to fail for Windows customers.
