The guys behind the WordPress blogging platform have released the next major update of WordPress, version 3.0 “Thelonious” (named after Thelnoious Monk, an American jazz pianist). Included are exactly 1,217 bug fixes, a bulk updater that can update all your plugins, themes, and WordPress installation at once, and a new, modern theme called “Twenty Ten”. Also overlooked is that this the version where WordPress MU and the regular version merge, meaning that it’s possible to run as much blogs as you want (even if it’s just one) from a single installation of WordPress.

When a new installation of WordPress is performed, the now-antique theme that came with WordPress 1.6 is no longer default. Instead a super slick, clean, and custom header capable theme is in its place. The theme can also be found in your Appearance panel under “themes”.

Whether if your hosting your installation at home or abroad in a data center, an upgrade to version 3.0 is a must have. If you’re a bit of a conservative person when it comes to software upgrades, it’s best to wait back a few days or weeks for critical security patches and other glitches to be flattened out. Or if you’re liberal on upgrades, the download is there for you take via the WordPress website or the update feature in your dashboard. Just be sure to back up your database first.

Also in the codex (the documentary), there’s a change-log since the last update. TechWay been using a development version of 3.0 since January and my impression is extremely satisfactory. The nightly build is now onto 3.1 alpha, with no noticeable differences between 3.0 and the current bleeding edge release.

Additionally, WordPress.com and WordPress VIP users need not to worry for latest updates. Automattic provides automatic updates and ensures your data will be secure.
