Plugin not updated in directory

http://plugins.svn.ww.wp.xz.cn/simple-keyboard-shortcode/

About a week ago I created a tag for version 1.1 of my plugin and updated the readme in trunk so that the stable tag was 1.1, however in the ww.wp.xz.cn plugin directory it still says version 1.0.

I’m new to SVN (having only used Git) so it’s probably something I’m doing wrong but I’d really appreciate some pointers.
