I think we are going to turn off the SVN builder for 3.4.

You will still be able to use your SVN directory, and we will continue to pull files from /dist (like readme.html and wp-config-sample.php). But, in order to create a build, you will need to import any po/mo files you have into the wp/dev projects at translate.wordpress.org.

GlotPress is all about collaboration. So others may help, it is preferred that you periodically import your po/mo files there (if you work with a separate tool), rather than importing them at the end in order to do a release. This also isn’t just about collaboration. At some point, I’d like to make it so you can mark your locale as “ready” for a release. Then we will simply create the build for you when we release WordPress.
