PHP 5.1.0 has finally come out of release-candidate status. At some point next
week we're going to try migrating; at that point we'll be able to make use of
new PHP 5 features in MediaWiki code, such as exceptions to simplify
error-handling, the improved XML reading support, etc.
This does mean that MediaWiki 1.6 will not run on PHP 4; it'll require PHP 5 or
5.1. Sorry for any inconvenience this may cause to third-party users on limited
hosts still running older versions.
