I understand and respect your decision to not release with something 
that breaks what worked previously.

However, I'd say a closer parallel would be if we introduced something 
that broke apps in Firefox 3.0.3 but not in 3.0.10.  Or if we introduced 
something that caused exceptions in Yahoo Maps v3.6 but not in v3.8.

I wouldn't be surprised if we have created issues like those above. 
However, if nobody complains, we can release with a clear conscience. 
When someone does point out a regression, we work to fix it.  I also 
think it makes sense to get an idea of the impact of the regression.
