I am wondering if someone has already noticed this. I got a plugin, I just uploaded a new version and it displays a notice stating:
This plugin hasn't been updated in over 2 years. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.
The funny thing is, it correctly displays the last updated date: 2012-10-22.
Here is the link to my plugin: http://wordpress.org/extend/plugins/network-latest-posts/
I don't know where to send feedback or bugs for WordPress plugin's directory so I posted this here.
