Depends on whether you mean commercial support or support via this 
mailing list. For commercial support there is some complicated formula I 
can never remember. For this list, we'll tell you if we think you're 
running too old a version (which will largely depend on what sort of 
problems you're having). If you have a basic question about how routing 
works I don't care what version you're running, but if you run into a 
known fixed bug we'll probably just tell you to upgrade. And if you run 
into a bug we think we might have fixed, we'll probably tell you to 
upgrade too.

We aim to make approximately two feature releases (i.e. 3.x.0) per year.

We aim to make a bugfix release (i.e. 3.2.x) approximately once per month.

No guarantees though, but that's the pattern we've roughly hit for the 
last couple of years.

The idea is that the stable branch just includes bug fixes (which 
includes security fixes obviously). However, some bug fixes won't go on 
the stable branch - anything which looks big and complex enough that it 
could be as destabilising as a new feature.

So far we have only introduced bug fixes for the "current" feature 
release - i.e. currently we are planning a 3.2.2 and 3.2.3 and so on, 
but I doubt there will ever be a 3.1.6 or 3.0.5 or 2.8.8.

That might change if there is a *lot* of demand. But we are a small 
team, so the demand would have to be substantial.

Cheers, Simon
