Today I finally upgraded to the new WordPress version. Version 2.13 and 2.0.10 have been released already on April 3rd, but due to the changes to WordPress core files by the modifications for the Language Switcher plugin, I wasn’t able to upgrade yet. Now the new files for 2.1.3 are available on Poplarware, and I could finally upgrade.

The new WordPress Versions can be found here, the files for the modifications here. Just upload the files from the upgrade package (“Upgradepaket für 2.1.2 auf 2.1.3″, can be used for both english and german WordPress), then the modified files, and then run upgrade.php.
