tuned;

use explicit Type.strip_sorts_dummy to suppress sort constraints in output;

printed "_ofsort" is subject to show_markup as well;

allow position constraints to coexist with 0 or 1 sort constraints; more position information in sorting error; report sorting of all type variables;

made tactic more robust (less usage of stac)

continued changing type of corec type

removed dead params and dead code

changed type of corecursor for the nested recursion case

made (co)rec tactic more robust when the simplifier succeeds early

tuned;

removed unused module Blob;

more direct message header: eliminated historic encoding via single letter;

tuned whitespace;

tuned proofs;

report sort assignment of visible type variables;

more robust File.eq, and thus File.copy of "~~/lib/logo/isabelle.gif";

fixed recursor definition for datatypes with inner products (e.g. "'a trm" from the lambda-term example)

tweaked corecursor/coiterator tactic

changed the type of the recursor for nested recursion

fixed quick-and-dirty mode

tuning

use Thm.close_derivation in theorems proved using Skip_Proof.prove; tuned signature;

got rid of subst_tac alias

tuned tactic

tuned proofs;

tuned proofs;

proper handling of constraints stemming from idtyp_ast_tr';

enable show_markup by default (approx. double output size);
