Just to clarify: No PHP 5.4 _required_ in FLOW3 this year - but starting with FLOW3 1.2, we'll officially support PHP 5.4 of course.

We don't have such guidelines written down for FLOW3 yet but plan to have some for the upcoming releases.

No breaking changes in patch-level releases, but it can happen that we have breaking changes in minor versions. The step from 1.0 to 1.1 is certainly bigger as the next steps will be.

I haven't put much thought into this, but it yes, it would be natural if we raise the dependency to PHP 5.4.x, to do so for FLOW3 2.x only.

This change is quite important, because if your code referred to "MVC\*" in the past, it did work on you local Windows dev machine, but would break in production on a Linux server.

I've been more or less involved in the PSR-* standards and I can tell that it's rather unlikely to establish a whole coding standard projects like Zend, Symfony, Drupal, TYPO3 and FLOW3 could stick to. PSR-1 certainly is a small compromise, but then again it doesn't allow us to use the same code sniffer set for all projects. 

So, if defining our standard was a waste of resource, it's already down the drain. But I don't think that it was, it actually paid off quite well.

Show me two significant frameworks with the same standards ;-)

Cheers,
Robert
