I’ve just upgraded this blog and a host of others that I help manage to the latest stable version in the WordPress 2.0 release: WordPress 2.0.3. The new release is both a bug fix and a security release. I would have procrastinated on the upgrading if not for the notice that it is a security release.
WordPress founding developer Matt Mullenweg wrote in the blogging engine’s development blog that the 2.0.3 release is “recommended for all WordPress users.”
In previous upgrades, I used to deactivate all the plugins then delete all the files before uploading the new ones and then running the upgrade script. But Matt said in his post that: “Upgrading is fairly simple, just overwrite your old files with the latest from the download. When you go to your admin it will give you a link to update your database.”
I did just that and upgrading took less than five minutes, including the uploading of the files.
