WordPress 2.0.2 released – Security update

WordPress v2.0.2 has been released with a number of security updates so it is well worth upgrading.

To simplfy the upgrade process I decided to try generating a diff file between 2.0.1 and 2.0.2 and using that to patch my sites rather than uploading a full set of new files.

Here is the process I took on my local machine to generate the diif file:

1. Exported both 2.0.1 and 2.0.2 from svn using the following commands:
   

   To get 2.0.2 - svn --force export http://svn.automattic.com/wordpress/branches/2.0
To get 2.0.1 - svn --force export http://svn.automattic.com/wordpress/tags/2.0.1


2. Generated a patch file using diff:
   

   diff -U3 -r 2.0.1 2.0 > 2.0.1.to.2.0.2.patch


I then uploaded the patch file to my server and placed it in my home directory and applied the patch as follows:

1. Backed up my WordPress database using the wp-db-backup plugin
2. Made a copy of my WordPress install files as a backup
3. Then to apply the patch you change into the root folder of your WordPress blog and enter the following patch command:
   

   patch -p1 < ~/2.0.1.to.2.0.2.patch


And it was done! – There are no database changes between 2.0.1 and 2.0.2 and so upgrade.php does not need to be run as far as I know.

To save you some time if you would like to use this method of upgrade you can download the patch file I generated here: 2.0.1.to.2.0.2.patch.

You use this file with out any guarantee that it will work – Remember to backup first!
