Since upgrading to version 2.1.8 on two sites, Akismet is not moving any spam comments it finds to its Spam queue. Instead, they all appear under Manage Comments. If I hit "Check for spam," they are correctly moved and appear on the Akismet "Caught spam" page. Has spam-handling been changed in this version? It's definitely behaving differently in the past week or so; I've been running Akismet for over a year and it's never done this before.
