For one type of rule, matching now ignores whether letters are upper or lower case:\n\n- a rule with no `*` wildcard is compared in a normalized form that ignores case, drops a trailing part and compares dot-separated names\n\n- a rule with a `*` wildcard is compared after both sides are made lower case\n\nThe normalized comparison only handles plain ASCII characters.\n\n**Why**\n\nRules of this type may now match inputs they missed before because of differences in case or formatting.\n\n- Area: Permissions\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: both\n- Heads-up: yes"}
