When it will come to choosing the best extension of the year for WordPress or if asked my opinion about any extension then Iíll choose WordPress Automatic Update (WPAU). This plugin automatically updates your WordPress to the latest version and it follows exactly the same steps which are mentioned in the WordPress upgrade guide.
Hereís what WPAU is capable of :
1. Backs up the files and makes available a link to download it.
2. Backs up the database and makes available a link to download it.
3. Downloads the latest files from http://WordPress.org/latest.zip and unzips it.
4. Puts the site in maintenance mode.
5. De-activates all active plugins and remembers it.
6. Upgrades WordPress files.
7. Gives you a link that will open in a new window to upgrade installation.
8. Re-activates the plugins.
I think Keith has done a wonderful job and deserves the appreciation from almost each and every WordPress user .
