Over the past few weeks I received quite a few translations submitted to me via email and through the support forum. My apologies for not having got to them earlier.
I have uploaded all the new translations and updates to old ones on the translations page. Thanks to the following folks for the new translations:
Translations have been updated for Dutch (Wim), German (Connie) and Simplified Chinese (Abe). Thanks, folks!
Please note that translations will not be included in the core theme starting from release 3.7.4. They will all be available from the translations page. The best way to use a translation will be to create a child theme.
