Just got finished upgrading my WordPress to 2.7 and so far so good I am digging the new admin panel look and I also decided to go ahead and add some plug ins as well on top of the upgrade. one of them being a sitemap generator which does exactly what you think it does.
There were a lot of security fixes since my last upgrade and I am happy no one decided to hack my blog. but one of the main reasons for me not upgrading was all the hassles that came along with it but now the new version 2.7 has a one button push upgrade from the admin panel so no more worries about that any more, thanks goodness.
