In June of 2009, mobalean release a patch for the WURFL containing Japanese handsets. This patch ignored the existing data on Japanese handsets in the WURFL as it was sparse and mostly incorrect. However, this also made it incompatible with the core WURFL, and applying the patch either required using one of the more lenient libraries, or manually editing the core WURFL.

After half a year, thanks to the hard work of the WURFL maintainers, these incompatibilities have been reconciled, and the data merged into the core WURFL. Any developer using the WURFL can now use it to start building Japanese sites right away.

Because our patch has been included in the core WURFL, we will no longer maintain a separate patch file. All new handset data will go directly into the core WURFL.

The updated WURFL is available through the WURFL project page.
