Then, yes, I misread the original post and apologise. I had assumed that the CentOS developers were planning on providing newer versions than the upstream source.
We do provide such packages ( eg. php5 and mysql5 ), in alternative non-core repositories. ( eg. CentOS Plus ). These are disabled by default. User intervention is required to get them enabled / setup. Using a standard install and not changing parameters on your package manager ensures you stay with the base distro, which tracks upstream only.
