thanks I will check it.

I had meant it for the future versions. ie. at what version level change
can I expect the compatibility to get broken (If there is a reason for
breaking it). To ask in a different way, If you find that you need to
break the compatibility between releases, which version number will you
increment?.
Any version in the 1.2.x line will be compatible in the sense, that
configs working for older versions will work at least as well for newer
versions. There have been very few exceptions, e.g. we sometime
introduced a new feature in some 1.2.x release and immediately observed
a problem with it's semantics, so we needed to change it in 1.2.(x+1).
Another example was, when we started to enhance the status worker a lot,
we broke the URL structure (query argument names). But we really try
hard to stay compatible in the 1.2.x line. If a feature is completely
new in 1.2.x, there is some risk, that we need to make a change to it
soon after the first release of it. We don't expect a lot of new
features for the existing mod_jk, it's pretty stable now.
The only other existing major jk version is mod_jk2, which is
incompatible from a configuration point of view and deprecated. Although
that project started later then mod_jk, it is no more alive and all
important features of mod_jk2 have been backported to mod_jk.
We have a plan to start a JK3. This again will be incompatible with
mod_jk and mod_jk2, but work didn't really start until now, so a first
release is still far away.
There is no mod_jk 1.3 or similar, and there are no plans for it.

Rainer
