That's how it is.  2.6 is backwards compatible with 2.5.

It's a version that makes the transition smoother.  You really should take
that "detour" via 2.6.  There should be some of the changes from 3.0 in 2.6
that don't mess with backwards compatibility, and a script that tries to
automate the conversion from 2.6 to 3.0.  This spares a lot of work when
porting to 3.0.
