just to clarify some aspects before the "Debian-bashing" goes on:

Debian Squeeze was released February 2011 and thus included 5.3.3, which
was the "cutting edge" stable PHP at that time. And Debian supports this
version until now, which is pretty amazing and is very welcome by most
enterprise application users which need to rely on such a stability for
a couple of years.

Not with Debian, because security fixes *are* backported to the released
version. Thus providing stability (no change in the API, no new
features), but still security:

All these *and much more* have been solved in Debian Squeeze already.
There have been 10 updated PHP 5.3.3 Debian packages since. The API and
it's feature set is since 2011 stable and can be relied on and there are
no known security issues.

And most amazing: This Debian support would work even if PHP declared
PHP 5.3 "obsolete" before Debian Stable was "end of live".

I can without blinking (even automate) a "aptitude upgrade" on all
production servers without worrying that it might break some of my
applications which already run. It's the same stability I have with 4.5
LTS by the way.

So this policy is not bad per se.

Might be, but I guess the point of Joey, Stucki and others is still
valid, and I can endorse that:

Debian Squeeze is still stable and very much liked in the enterprise and
hosting area, and thus TYPO3 should be really considered.

BTW: RedHat Enterprise Edition 6 (current latest RHEL in the market) was
also released early 2011 and also *still* includes PHP 5.3.3
(5.3.3-22.el6). Both RHEL and Debian will most probably release a next
release this year (and will include PHP 5.4 then).

About TYPO3 6.x: I know the effort done with the "hotfix" in order to
circumvent the auto-loading issue of PHP 5.3.3, because I was also
involved in reviewing it (http://forge.typo3.org/issues/40653). If this
is indeed the only issue that might hinder 5.3.3 users to use 6.0
(considering extensions adopt auto-loading), I guess we're on track.
There aren't any other known issues for this combination yet, right?
