No, I said I would cut a 2.6 *before* the planned release data, with 
come features pushed into 2.7, if you guys were willing to accept it 
into AS 5. Of course, since this is more work for me, I would not mind 
if I didn't have to do it ... :-)

2.6 is backward compatible with 2.5 if you don't use the new connect() 
call added in 2.6.

That is my understanding too. And if we go for 5.0/2.5 and 5.1/2.6, then 
we would *not* support the 5.1/2.6 combo; according to the standard Red 
Hat policy, customers would have to upgrade to 5.1 to use 2.6.

I'm interested in the answer to this too...

My yes was to "is it absolutely necessary to throw exceptions?", *NOT* 
to "is upgrading to 2.6 a must", maybe that's the src of the confusion.

No, not true, they can if you don't use the new connect() methods.
