I just upgraded to Pretty Link 1.6.3 and immediately discovered two significant bugs.
1. Pretty Link is still notifying me to update … backwards?
You have version 1.6.3 installed. Update to 1.6.2. View version 1.6.2 details.
2. Pretty Link Pro is broken. After updating to 1.6.3, my WordPress notifies me, "Automatically Upgrade to Enable Pretty Link Pro." Clicking that returns, "The plugin is at the latest version," and the pro features are never unlocked.
