Adobe have posted Lightroom 2.6.1 to their servers. This is not available via the normal update mechanism.

This 2.6.1 update contains a single change compared to 2.6: a fix for the problem that would cause LR to crash when processing some M9 files, primarily observed by users under 64-bit, but occasionally under 32-bit as well. There are no other changes.
Aperture has no bearing on the release cycle for Lightroom. And Adobe has made any public hints to ascertain when that might be.
We do have a public Beta for 3 since last October. That will run until 3 is ready to go.
When do you think Lightroom 3 will be launched now that Aperture 3 has been announced?
I'm a big fan of Lightroom and think it has the edge over Apple's offering but I'm still on version 1.3 and obviously don't want to upgrade to version 2 only to find that weeks later I have to pay for Lightroom 3.
