I'm not sure I understand your question (or perhaps I didn't phrase my comment clearly).JoshyPHP wrote: ↑Sun Sep 13, 2015 11:38 pmPHP 5.5 has been in most Linux distros for months, maybe more than a year by the time phpBB 3.2 is released. Are there really users who upgrade their OS software every other year but want to use PHP software on the day of the release?
One of CentOS's strong points is that they do not continually update RPM packages with the "latest and greatest" release. It's all about maintaining a stable environment. (Ref: CentOS FAQ)
This is a very different environment than bleeding-edge releases, such as Fedora (the upstream version of Red Hat) which updates every year.
Combining a 10 year support cycle, along with focusing on stability, is a very strong selling point and is probably why CentOS is in the top 10 for server distros.
I'm not a fan of any particular OS. My point is that you need to support the major OS releases, as the decision to update software is not a trivial one. VSE's list of "popular server software" makes this point clear.
Decide if the features on 3.2 warrant breaking the earlier PHP releases and proceed from there.
