==============================================
-* print modes "type_brackets" and "no_type_brackets" control output of nested
-=> (types); the default behaviour is "brackets";
-
-* Classical reasoner: renamed addaltern to addafter, addSaltern to addSafter
+* HOL: added "The" definite description operator;

* HOL: introduced f^n = f o ... o f
WARNING: due to the limits of Isabelle's type classes, ^ on functions and
relations has too general a domain, namely ('a * 'b)set and 'a => 'b.
This means that it may be necessary to attach explicit type constraints.
-* HOL: added safe wrapper "split_conv_tac" to claset. EXISTING PROOFS MAY FAIL
+* HOL: added safe wrapper "split_conv_tac" to claset. EXISTING PROOFS
+MAY FAIL;
* HOL: made split_all_tac safe. EXISTING PROOFS MAY FAIL OR LOOP, so in this
(rare) case use delSWrapper "split_all_tac" addSbefore
