Well, PHP 5.3 is the current stable, it is not like it is that old (3
years already tho').

Well, things may change as we have now some stricter rules when it
comes to BC breaks and related areas.

If you can list the ones which have unit tests, then we should
definitively do test them now and here using php's snapshots. If your
team could get this list shortly, we can them share resources to setup
the automating testing. We already do that in our labs for a couple of
applications and php's unit tests. Frameworks are coming too.

Yes, and maybe the upstream teams of the respective apps would be
willing to help. But it is a huge communication effort and any help is
welcome. I'm working with some apps and  mainly with frameworks lately
(symfony being the most active here).

I would suggest to read the following RFC and todos:


I would not expect to have 5.4.0 final out before end of december or
early next year. The rest is defined by the RFC. I think we can expect
more frequent releases than what we used to do, but smaller, which is
actually better.

That's something we can try to work together, by contacting the
respective teams and get tests infrastructure together. The key is to
get the testing results as frequently as possible.

Thanks for coming to us to discuss this, it is very appreciated!
