Note: this file isn't used anymore. Incompatibilities are documented as part of CHANGES. Incompatibilities beyond 8.4... - Syntax: "x -> y" has now lower priority than "<->" "A -> B <-> C" is now "A -> (B <-> C)" - Tactics: tauto and intuition no longer accidentally destruct binary connectives or records other than and, or, prod, sum, iff. In most of cases, dtauto or dintuition, though stronger than 8.3 tauto and 8.3 intuition will provide compatibility. - "Solve Obligations using" is now "Solve Obligations with".
