Canon USA has posted a PDF indicating that some people are experiencing problems with the new version 2.03 firmware. Here is the full text of the announcement:
"Thank you for using Canon products.
We have learned that some users of the Canon EOS 5D Mark II digital SLR camera are experiencing issues with Firmware Update Version 2.0.3.
We are working on a new firmware update to address these phenomena, which will be available soon.If you have not registered your EOS 5D Mark II, please register so we will be able to notify you via email when future updates become available for download.

Apparently the specific problem has to do with sound recording not working when a manual record volume is used in the C modes. Update from Canon:
"Recently we have discovered a malfunction that occurs with Firmware Version 2.0.3, in which the manual recording levels for C1/C2/C3 are changed and the camera becomes unable to record audio if the power is turned off (or if Auto power off takes effect) after registering "Sound Recording: Manual" in the camera user settings.
We apologize very sincerely for the inconvenience, but we are going to stop making this firmware available for download. For customers who have already updated to the new firmware, when using the camera with the mode dial set to C1/C2/C3, please either set the sound recording settings to Auto.
We are currently preparing firmware that will correct this malfunction. As soon as those preparations have been completed, we will let you know on this Web site. In the meantime, we apologize for the inconvenience this represents, but please wait until the fixed firmware is ready."

ISO 12233 Chart results for a second lens copy have been added to the Canon EF 70-200mm f/2.8 L IS II USM Lens Review
page. Select "Sample 2" in the ISO 12233 chart tool.
The second lens appears to be even sharper at f/2.8 at the 70mm end and slightly softer at f/2.8 at the long end compared to my first copy of this lens.
Vignetting results and a flare comparison test have also been added to the review. Vignetting performance appears mostly similar to the version 1 lens - slightly improved in the mid-range focal lengths. The flare comparison (posted by request and yet un-narrated - at bottom of the review page) shows another great advantage the new lens holds.
