We also want to keep the dates removed. After reading the comment section here: http://yoast.com/wordpress-seo-1-2/ I added the the new filter code that was also noted in the readme as being added to the plugin
After reading that other user's said this didn't work, I searched the plugin and there isn't any code anywhere in the plugin for that to work.
I did find the snippet preview code under the visual editor and was able to remove the date from it by adding this to the functions.php of the theme:
add_filter( 'wpseo_show_date_in_snippet_preview', false);
But it's more important to be able to remove the date from the search listings. Is it possible that the new code for the wpseo_show_date_in_snippet filter didn't get committed properly to the wp codex?
It would be great to have this feature back whether it's a simple checkmark in the wp-admin or having to add the filter to the theme.
The biggest issue on the dates is on the shopping sites. We don't want dates showing on the product search results.
Thank you very much for your time and the great work you've done on this plugin - I'll offer any help needed to work on this issue.
