Sorry for a bit late report though its not even 24 hours since WordPress 2.3.1 has been released. This new release fixes 24 bugs of which 1 is a serious security bug. This new release adds support for Tags in Windows Live Writer though its possible in 2.3 via a hack. Also 2.3.1 promises to be faster in performing taxonomy operations.
Bored of Updating WordPress Again and again and redownloading? Want to do without a plugin but fastly. For updating WordPress 2.3 to 2.3.1 download this zip file and extract all the files and overwrite on your 2.3 blog directory. This zip file is only for updating from 2.3 to 2.3.1
I did the same to my blog, so trust me. 😎
