I just ran the upgrade to WordPress 2.7 on laresweb.com. On the outside, you won’t notice any difference unless you look very closely at the footer information at the bottom of the page. On the inside, WordPress 2.7 has a completely reworked administrative interface. It will take some getting used to, but at first glance, it’s a major improvement over past versions.
Drop me a line if you tinker around with hosting your own WordPress or any other blogging system.
