WordPress 2.0.3 has been released, incorporating security fixes, small performance enhancements, a Movable Type and Typepad importer fix, and a podcasting (enclosure) fix. 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 2.0.2, you obviously don’t need the entire install, you just need the files that have changed. Don’t worry, I’ve got your back.
Changed Files List
Changed Files List (2.0.2 » 2.0.3)
This is a list of all the files that have changed since the last (2.0.2) release. You can also see the changes and their corresponding tickets on Trac.
Changed Files ZIP
Changed Files ZIP (2.0.2 » 2.0.3)
This is what most people will want. This is a zip file that includes only the files that have changed since the last (2.0.2) release. This will save you a lot of FTP upload time.
Note: the /wp-content/ directory isn’t included in this file, to keep you from doing something stupid like replacing instead of merging and destroying your precious themes and plugins. Two of the default plugins have been updated for 2.0.3. If you use either of these plugins, you should download their newest versions: WordPress Database Backup, Akismet
Changes Diff
Changes Diff (2.0.2 » 2.0.3)
This is a diff file (a patch) with all the changes made since the last (2.0.2) release. Make sure you do a trial run by using the patch command’s --dry-run switch, to verify that the patch will apply cleanly.
Disclaimer
I prepared these files myself, and used both the zip and the diff to upgrade sites that I manage. 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!
Update
Make sure you check out this fix for 2.0.3’s rather annoying “Are you sure?” dialog popping up when you edit comments and adding slashes to the comment you’re editing.

Thanks Mark, we really appreciate the diff and zip for these intermediate upgrades as it makes our life so much easier. I would encourage the devs to adopt them officially.
Do you do this for every release? If not, can you? This is invaluable, and honestly something I think should be an Official Task of the release team.
Ed,
I provided a “changed files only” zip for the 1.5.2 to 1.5.3-beta upgrade (1.5.3 is an unsupported SVN-only release that just fixed a few security problems with 1.5.2 for people who were not yet ready to upgrade to the 2.0 branch). But this is the first time I’ve done it for the main stable branch. I can definitely do it again. It’s not too hard… diff the directories, clean up the diff, extract the filenames, and then use the extracted filenames to copy the changed files to a new directory… zip it up and it’s good to go.
Thanks for getting the patch and changed files list out so quickly, really saved me a lot of time.
Thanks again!
Many thanks, Mark!

Very nice post.
About file hosting, i usually use yoUpload.com to upload all my files. I believe that is the best, but it’s my opinion, ehehe…

This operation can do with help-zipfix download,my friends recommend it for me also as how as they said it is free,utility can help you and recover corrupted documents,program can extract your documents from a Zip archive, it is easier, than you thought,fixing a zip file may be needed on a regular basis for fix broken .zip and fix the corrupted zip on cd, if you often work with archivers,use several algorithms to check the results and fix compressed zip broked files, it can guarantee, that in the most cases your archive will be successfully recovered.
You saved my life 😉
Thanks!!!
