Subject Re: [DISCUSS] - Trunk as Camel 3.0
Date Sat, 24 Sep 2011 13:48:08 GMT
I don't think we're debating if, we're debating when. I get your point 
and I would agree if this was any different than before. The reality 
though is that *every* single minor release of Camel was *not* 100% 
backwards compatible. We absolutely strive for backward compatibility 
and 2.9.0 should not be worse. We should be 100% compatible in patch 
releases though.

The reality is that when we'll start working on 3.x we won't have it for 
at least 9 months, most likely. Nobody will migrate to a 3.0-Mx 
milestone release. It's also likely that many won't migrate to a new 2.x 
while we actively work on 3.x. In the patch releases we only have a 
small subset of the new features on trunk.

I know some are kinda tired of 2.x and want to look at and talk about 
the next great thing. We had this discussion a year ago and promises 
were made that 3.0 will be out in Q1 2011. We don't yet know how 3.0 
will look like, although many have their ideas. We know that we want a 
cleaner api, we know we want it leaner and we know that we want shorter 
build times and other few things. We can easily continue to work on that 
and the other features that come with every release until we figure out 
how 3.0 will look like. Doing it now is, imho, a distraction.
