WordPress 3.0 在十幾分鐘前 release 了。
2.9.2 升級可直接把下載下來的壓縮檔直接覆蓋原本的目錄，再透過瀏覽器執行升級程式（ wp-admin/upgrade.php ）。
因為 WordPress 3.0 的預設佈景主題換了，所以沒改過預設佈景主題的人記得開管理後台檢查一下。
WordPress 3.0 的壓縮檔裡面沒有這些檔案與目錄（注意： wp-content/themes/classic 與 wp-content/themes/default 列在其中），想讓目錄乾淨一點的可以清掉：
- wp-admin/categories.php
- wp-admin/edit-category-form.php
