I agree it is not a competitive Web server and yes i am being a bit over dramatic. It is just that 5.3 has been out a very long time and there has been no visible movement to update the software. Mysql is also way behind too.
While it's obviously not a competitive webserver it is being positioned as a NAS with apache webserver and php capabilities.
And as far as those are concerned they are on the extremely meager implementation side.
- PHP version well out of support - Apache not supporting basic functionality. It is impossible to run SSL certificates on virtual hosts without running into ubiquity issues for Firefox, regardless if you want to use it as an intra-/inter- or extranet server. - MySQL out of date
We are soon going to see the other end of the spectrum which is that we won't be able to update some of the packages because developers simply stop using/supporting deprecated PHP versions (with good right).
