We changed the upgrade process for MySql, you need to copy the contents of the Setup folder from the MySql data layer download into your /Setup folder and visit the setup page again. Previously we included the MySql scripts in the MS SQL download but we changed this to reduce the size of the MS SQL download.
That field "IsPublished", is added to the blog in the 0.0.1.3 script for the blog. You can see feature versions from Administration > System Info
Hope it helps,
Joe
