WordPress upgraded more or less painlessly. However, Joomla stopped working. There appear to be issues with my (admittedly bodged) theme that I could not quickly get around. I have now rolled that back - I suppose I will have to fix it properly eventually.
As for PhpGedView, I now see an error at the top of each page. Searching the Internet for possible solutions only took me to a number of other sites that display the same error. Not really important I suppose, it's not like I ever got around to using it properly anyway. Another job for a rainy day...
My blog and homepage do now have a "better" link to my LinkedIn profile page though!
