WordPress 4.9.4 Maintenance Release

Posted February 6, 2018 by Dion Hulse. Filed under Releases.

WordPress 4.9.4 is now available.

This maintenance release fixes a severe bug in 4.9.3, which will cause
sites that support automatic background updates to fail to update
automatically, and will require action from you (or your host) for it
to be updated to 4.9.4.

Four years ago with WordPress 3.7 “Basie”, we added the ability for
WordPress to self-update, keeping your website secure and bug-free,
even when you weren’t available to do it yourself. For four years it’s
helped keep millions of installs updated with very few issues over that
time. Unfortunately yesterdays 4.9.3 release contained a severe bug
which was only discovered after release. The bug will cause WordPress
to encounter an error when it attempts to update itself to WordPress
4.9.4, and will require an update to be performed through the WordPress
dashboard or hosts update tools.

WordPress managed hosting companies who install updates automatically
for their customers can install the update as normal, and we’ll be
working with other hosts to ensure that as many customers of theirs who
can be automatically updated to WordPress 4.9.4 can be.

For more technical details of the issue, we’ve posted on our Core
Development blog. For a full list of changes, consult the list of
tickets.

Download WordPress 4.9.4 or visit Dashboard → Updates and click “Update
Now.”
