WordPress 2.2.1 Upgrade: changed files ZIP, changes diff, changed files list

WordPress 2.2.1 has been released, incorporating multiple security fixes. This is a mandatory upgrade. If you want the full zip with the entire WP install, download it here.

If you are upgrading from WordPress 2.2, you obviously don’t need the entire install, you just need the files that have changed. Because my previously offered upgrade files were so popular (and thanks to countless words of praise and even a few generous monetary donations), I’m going to continue to provide the same files for this and future in-branch upgrades.

Changed Files List

Changed Files List (2.2 » 2.2.1)
This is a list of all the files that have changed since the last (2.2) release. You can also see the changes and their corresponding tickets on Trac.

Changed Files ZIP

Changed Files ZIP (2.2 » 2.2.1)
This is what most people will want. This is a zip file that includes only the files that have changed since the last (2.2) release. This will save you a lot of FTP upload time.

Note: this does NOT contain updates to any files within wp-content. I do this to prevent people from accidentally deleting all their themes and plugins. The Akismet plugin was updated, as was wp-content/themes/default/functions.php. If you are using the Akismet plugin of the Default (Kubrick) theme, you MUST upgrade these files manually. You can get them from the official (full) download file.

Changes Diff

Changes Diff (2.2 » 2.2.1)
This is a diff file (a patch) with all the changes made since the last (2.2.1) release. Make sure you do a trial run by using the patch command’s --dry-run (or equivalent) switch, to verify that the patch will apply cleanly.

Note: two files have been added that cannot be included in the diff:

  • wp-includes/js/tinymce/themes/advanced/css/colorpicker.css
  • wp-includes/js/tinymce/themes/advanced/images/colors.jpg

You will have to add these files manually. You can find them in the full download or in the Changed Files Zip download above.


I prepared these files myself and have tested them. Still, I cannot stress enough the importance of making a full file and database backup before attempting to upgrade WordPress using these or any other files. I cannot be responsible for your carelessness. Make a backup!

I should mention that these files are unofficial. They were made on my own time, of my own volition, without any input from other WordPress developers.
