XAMPP has different developers with different standards.
The ex-XAMPP developer Carsten Wiedmann released very detailed release notes for every XAMPP version on sourceforge ( e.g. http://sourceforge.net/projects/xampp/f ... 3.txt/view
Since XAMPP 1.7.4 the developer for Windows has changed to Kay Vogelsang who has a different way for release notes.
Solaris and Linux are developed by the same developer Kai 'Oswald' Seidler, so not surprising that the release notes are made the same way.

You are free to use the stack which fits your needs. Maybe XAMPP is not the right stack for you, i don't know. There are always things which can be made better, even for XAMPP.
