Every month the BugBlog picks its Bug of the Month, representing the most significant bug found in the past month. Sometimes, the bug will be the one which could potentially cause the most damage; sometimes it will be the bug which affects the most users. And sometimes, it will be the bug that is just the most interesting. This bug will be selected either from the free Bug of the Day, or from the subscription-only BugBlog Plus.
