Forum Unclear about what to do with PL4
 

I had just finished the PL3 upgrade, and I noticed the PL4 release.

In order to remain up to date I was going to continue with the PL4 upgrade, but it is unclear of what I should do.

Quote:
There is no need to run an upgrade script if you are already running the latest version (4.0.2 PL3).

If you are running 4.0.2, or 4.0.2 PL1 you should follow these steps.
1) Download the 4.0.2 PL4 patch files.
2) Set your site to be offline.
3) Make sure your install directory still exists. If not, upload the install directory from your vBulletin package to your vBulletin directory, leaving out install/install.php.
4) Upload the patch files to your vBulletin directory.
5) Run the url http://your.site.com/vBdirectory/ins...e_402_salt.php
6) Set your site to be online.
This will address all PL fixes, including the fixes contained in 4.0.2 PL3. It is not necessary to run any other scripts.


Is it just a file replacement I should do?
Or do I need to run salt.php again?

What is the upgrade path for PL3 to PL4?
