Of course I do, but I would say that saying 5.4 is 'extremely incompatible with 5.3' is also nitpicking. Which is why I doubt 5.5 will see dramatically different adoption rates from 5.4. If anything, having O+ inside 5.5 would help - although personally I think that the reason people aren't upgrading to 5.4 isn't just the fact APC wasn't available. It's simply not a priority for them as earlier versions are already doing everything they need, and if it ain't broke - don't fix it. > I have to suggest to join me in the next conferences then.

As weird as it may sound - developers typically don't get to choose what version of PHP they run on, beyond perhaps the initial setup. Operations people do. And they won't install PHP 5.5 because Pierre tells them it's 100% compatible. They'd need to (a) have a good reason to upgrade (b) have it prioritized high enough over all the other things they need to do (c) have apps fully tested before they roll a version out. I, for one, wouldn't dream of rolling out PHP 5.5 without fully testing that nothing broke, and I'm not exactly a very conservative ops person. > I suppose you refer to my comments about us being out of sync with our user > bases, let say you talk to part of our users and I do to another. I refer to your lack of respect for pluralism, the fact that other people may have a different opinion, and that possibility that you may simply not be right. Just in case it wasn't clear - I very much admit the possibility that I may be wrong, and that the yearly cycle is a good thing. Everything I know about how PHP is actually being used in production tells me otherwise, but you're not going to hear something along the lines of "it's not my opinion but a simple fact", even if though I very strongly believe in what I say. > Amazingly most of the frameworks and apps lead developers think the same > have the same opinion, go figure. If 5.3 was any indication, then the leaders of the two biggest frameworks barely made the decision to switch to PHP 5.3 almost a full year after it came out, and that's just as they were gearing up to *start* developing. Drupal 8, that just came out - doesn't take advantage of PHP 5.4 features, and only discontinued support for PHP 5.2. WP still supports 5.2, and therefore doesn't even take advantage of PHP 5.3 features. The list goes on. Could it be that you're just a tad bit too self-confident with the yearly release cycle? I know you'd say 'no', the question is directed to others reading this message. Zeev -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
