I upgrated to 1.5 about a month ago and noticed through Google sitemaps, that a lot of my posts went 404, because of duplicate titles. It appears that 1.5 has changed them to /post-2/. Out of 8 posts I just caught today, all of them had se ranks, pagerank and inbound links that I'd hate to lose. Is there any way to go back to modify anything so you can have the duplicate titles, just different date slugs? Any work around this? Thanks.
