Phil has signalled a flaw on the Subtext 2.0 engine and so the upgrade was a must.
From now my blog runs on Subtext 2.1.
I've read that there are ideas on moving Subtext to ASP.NET 3.5. This is for me a great idea (at least for Subtext 3.0), but I think that not all the hosting providers are ready now for ASP.NET 3.5 so I've a little request to the team: please maintain the ASP.NET 2.0 versions at least for a while...
