I only just noticed that WordPress 1.5.2 has been released. Took, oh, about 30 minutes to upgrade this site, that site and an other site.
Also, MediaWiki 1.4.12 was released last week. Took another 30 minutes to upgrade that site and that one of there.
’tis important to keep web software up to date otherwise you might end up getting hacked like the IrishGaming.com forums did today.
