到目前为止，WordPress 2.8.1 beta1 主要解决了以下问题：
Certain themes were calling get_categories() in such a way that it would fail in 2.8. 2.8.1 works around this so these themes won’t have to change.
Dashboard memory usage is reduced. Some people were running out of memory when loading the dashboard, resulting in an incomplete page.
The automatic upgrade no longer accidentally deletes files when cleaning up from a failed upgrade.
A problem where the rich text editor wasn’t being loaded due to compression issues has been worked around.
Extra security has been put in place to better protect you from plugins that do not do explicit permission checks.
