I mantain a plugin which is hosted on https://wordpress.org/extend/plugins/indypress/
- I have updated the plugin, as you can see ( https://plugins.svn.wordpress.org/indypress/ )
- the version has been updated to 1.0
- the readme file correctly point to that tag
- The readme validator doesn't complain.
However, the plugin page still says "0.5.1". What's wrong with my plugin?
