If you are upgrading from WordPress 2.1.2, you obviously don’t need the entire install, you just need the files that have changed. Because my upgrade files for 2.0.3 through 2.1 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 2.1.x upgrades.
Changed Files List
Changed Files ZIP
Changed Files ZIP (2.1.2 » 2.1.3)
This is what most people will want. This is a zip file that includes only the files that have changed since the last (2.1.2) release. This will save you a lot of FTP upload time.
Changes Diff (2.1.2 » 2.1.3)
This is a diff file (a patch) with all the changes made since the last (2.1.2) release. Make sure you do a trial run by using the
--dry-run (or equivalent) switch, to verify that the patch will apply cleanly.
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 and without any official sanction from Automattic inc.
