Sixapart released Movable Type 4.01a today. It is a Security Update.
No matter MT 3.2, MT 3.3x or MT4.01, upgrade is required.
For MT4.01, just download the gz package and decompress it. Overwrite the MovableType 4.01 installation is OK.
No database upgrade this time.
It said, “Security Release. The potential vulnerability has not yet been exploited in the wild.This is a mandatory update for all users of Movable Type.”
So I did it as it said.
I used five steps to upgrade it.
1) Fully Backup
Backup database through PhpMySQL, Tar and compress all files into one file, and export all entries by build-in function.
2) Get package
SSH to Server, wget the file.
3) Decompress package
tar xvzf MT-4.01a-eb.tar.gz
4) Copy and overwrite the installation
5) Login the system and click upgrade if asked.
The SSH is provided by Dreamhost.
