Wordpress has released another upgrade within 10 days of 2.0.6 release. They had no choice since 2.0.6 had serious problem with FeedBurner. Also now people are trying hard to find security issues, so I think we can expect fixes frequently like we see Microsoft patches!

Also I recommend waiting atleast a day or two before applying latest Wordpress patches. You never know whether upgrade itself will cause serious issues like the FeedBurner problem!

Wordpress 2.1 release may happen sometime in February 2007. Official site says that 2.0 series will be supported for many years. I doubt that statement since years in the age of internet is like centuries
