Stable version?

Stable version?


I was looking around for a stable version of JQuery.
It seems that bug fixes are rolled into new versions rather than just
extending the 1.7.x tree to just include bug fixes.
Is there a version which will extend by only including bug
fixes and no new concepts so that new technology doesn't break
old features?
I was disappointed to find that after two rounds of bug fixing
(ie 1.7.2 being two updates from 1.7.0) that a simple test of
JQuery revieled many cross browser differences. Since cross
browser compatibility is the reason I am looking to a framework,
and one of a frameworks major deliverables, I find it interesting
that the quality is not being delivered.
I would just switch to another framework, but it is fundamentally
tied into another framework I am using, so I have no choice but
to use it. All I need now is a stable version.
Many thanks
Adrian.
