WordPress.org has finally released WordPress 2.8.1 fixing several bugs in 2.8, tightens security for plugin administration pages (certain plugins could be viewed by unprivileged users), and a host of other changes such as the following:
- 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.
- Translation of role names fixed.
- wp_page_menu() defaults to sorting by the user specified menu order rather than the page title.
- Upload error messages are now correctly reported.
- Autosave error experienced by some IE users is fixed.
- Styling glitch in the plugin editor fixed.
- SSH2 filesystem requirements updated.
- Switched back to curl as the default transport.
- Updated the translation library to avoid a problem with mbstring.func_overload.
- Stricter inline style sanitization.
- Stricter menu security.
- Disabled code highlighting due to browser incompatibilities.
- RTL layout fixes.
The easiest and fastest way to upgrade is to use the Automatic Update plugin if you have it or you can go to WordPress.org to download and manually install the upgrade.
So far, I have not encountered any problems yet!
