Same here. This update kills the WordPress installation!
Not even a standard restore in my web host Direct Admin panel managed to fix this.
Had to manually remove both the database and all files/folders and then do a restore from scratch!
So a tip to all in same situation (considered that you have a full backup of database and files/folders).
– Remove Database completely.
– Remove all files/folders from WP installation directory.
– Restore your previous backup of database and files/folders.

Hope the developers fix asap. This is really bad, to not check the code thoroughly before distributing the update!

Same problem for me – plugin stalls on update.

To remedy for others having the same problem – ftp to the server and delete the maintenance file in the base wordpress directory which will stop the update and bring the site back up for you.

Thanks sjo007, that solution is even easier.
Hope they fix this issue soon and pull back this update asap.

Update:
WP admin is back again. Obviously updating process stopps autimatically after one hour or so. So I would recommend to do nothing but to wait a while. In my case this is solving the problem.

But the developers should offer a new update version immediately.

Hi,
We are very sorry about that issue.
