Subject Re: [VOTE] Release candidate 0.20.203.0-rc1
Date Thu, 05 May 2011 00:05:50 GMT
Hi folks,

Let's stay focused. Let's take the other threads onto other threads. This is a vote. 

To the extent naming is a problem, let's take that to a thread and find an acceptable proposal.


To the extent folks want to collaborate on certifying the release for total lack of regression
or collaborate on the cleanest possible merge, I think all interested parties should take
these topics to another thread and divide up the work. 

If you've voted, you don't need to comment further on this thread, no matter what company
you work for!

Thanks,
