1998-09-24 oheimb 1998-09-24 renamed mk_meta_eq to mk_eq
1998-08-17 paulson 1998-08-17 Yet more removal of "goal" commands, especially "goal ZF.thy", so ZF.thy contains fewer theorems than before
1998-07-27 paulson 1998-07-27 A few new lemmas by Mark Staples
1998-07-13 paulson 1998-07-13 Huge tidy-up: removal of leading \!\! addsplits split_tac[split_if] now default nat_succI now included by default

1997-10-14 nipkow 1997-10-14 Added neagtion rules for Ball and Bex. ZF/AC now fails to build. Larry to fix.
1997-10-10 wenzelm 1997-10-10 fixed dots;
1997-06-06 paulson 1997-06-06 Better miniscoping for bounded quantifiers
1997-04-02 paulson 1997-04-02 Uses ZF.thy again, to make that theory usable
1997-01-09 paulson 1997-01-09 Removal of needless "addIs [equality]", etc.
1997-01-07 paulson 1997-01-07 Default rewrite rules for quantification over Collect(A,P)

1996-06-07 paulson 1996-06-07 Addition of converse_iff, domain_converse, range_converse as rewrites
1996-03-26 paulson 1996-03-26 Added new rewrite rules about cons and succ
1996-01-30 clasohm 1996-01-30 expanded tabs
1995-04-13 lcp 1995-04-13 Recoded function atomize so that new ways of creating simplification rules can be added easily.
1995-01-12 lcp 1995-01-12 Added singleton_iff, Sigma_empty1, Sigma_empty2, Collect_simps and UnInt_simps to ZF_ss. Added consI1 to ZF_typechecks.
1994-12-08 lcp 1994-12-08 test_assume_tac: now tries eq_assume_tac on exceptional cases (formulae not of the form a:?A). Affects typechk_tac.
1994-08-16 lcp 1994-08-16 ZF/pair.ML: moved some definitions here from simpdata.ML
1994-08-12 lcp 1994-08-12 installation of new inductive/datatype sections
1994-07-26 lcp 1994-07-26 Axiom of choice, cardinality results, etc.
1994-07-12 lcp 1994-07-12 new cardinal arithmetic developments
1994-06-21 lcp 1994-06-21 Addition of cardinals and order types, various tidying
1994-03-17 lcp 1994-03-17 Improved layout for inductive defs
1993-09-30 lcp 1993-09-30 ex/{bin.ML,comb.ML,prop.ML}: replaced NewSext by Syntax.simple_sext domrange/image_subset,vimage_subset: deleted needless premise! misc: This slightly simplifies two proofs in Schroeder-Bernstein Theorem ind-syntax/rule_concl: recoded to avoid exceptions intr-elim: now checks conclusions of introduction rules func/fun_disjoint_Un: now uses ex_ex1I list-fn/hd,tl,drop: new simpdata/bquant_simps: new list/list_case_type: restored! bool.thy: changed 1 from a "def" to a translation Removed occurreces of one_def in bool.ML, nat.ML, univ.ML, ex/integ.ML nat/succ_less_induct: new induction principle arith/add_mono: new results about monotonicity simpdata/mem_simps: removed the ones for succ and cons; added succI1, consI2 to ZF_ss upair/succ_iff: new, for use with simp_tac (cons_iff already existed) ordinal/Ord_0_in_succ: renamed from Ord_0_mem_succ nat/nat_0_in_succ: new ex/prop-log/hyps_thms_if: split up the fast_tac call for more speed
1993-09-17 lcp 1993-09-17 Installation of new simplifier for ZF. Deleted all congruence rules not involving local assumptions. NB the congruence rules for Sigma and Pi (dependent type constructions) cause difficulties and are not used by default.
