I couldn't wait to upgrade to the new 1.7 version of dasBlog Community Edition (as it's called nowadays) because of all the great new features: far better performance, anti-spam measures, drafts (finally!), and lots more. Three cheers to Omar Shahine, Scott Hanselman, and everybody else who dedicated some precious time to it!
Unfortunately, there seems to be a small bug in the drafts functionality, since posts that aren't marked as Public (i.e. drafts) still show up in the RSS feed. Whoops 
I'll be keeping an eye on the bug I submitted to the SourceForge tracker because I really want to start using drafts... Update: My eyes must be deceiving me, the draft version of this post worked perfectly without showing up in the RSS feed... It did fail on my test machine though... Anyway, I'm sure it was my fault then.
If you're planning on upgrading too, you'll notice that you have to run an upgrade tool against your contents directory. The fix for the "Comments may disappear when moving content across GMT timezone boundary" bug I briefly mentioned before and submitted to Omar Shahine may have something to do with that since I believe that triggered the filename changes, sorry about that
Still, I had a little problem upgrading my content, and I believe it's related to that bug. I pulled the content from my server (which is on time zone GMT-7) to my machine (GMT+2) and ran the upgrade tool. Everything seemed fine on my test machine, but I noticed that the comments on some (what appeared to be) random posts had disappeared. I dug a little deeper and noticed these posts were submitted quite early in the night so I suspected a time zone issue again. I reflectored (uhm, yes, that's a word) the upgrader exe to see what it was doing and I noticed it was using the local time zone for some date-time calculations. So on a hunch I switched my local timezone to the one of my server and everything worked just fine. Whew 
So here's a word of advice: if you upgrade your content directory, be sure to temporarily set your local machine to the same time zone as the server the blog will be running on!
