2014-02-17 blanchet 2014-02-17 renamed old 'primrec' to 'old_primrec' (until the new 'primrec' can be moved above 'Nat' in the theory dependencies)
2013-12-02 blanchet 2013-12-02 generalized datatype code generation code so that it works with old-style and new-style (co)datatypes (as long as they are not local)
2013-11-12 blanchet 2013-11-12 moved 'Ctr_Sugar' further up the theory hierarchy, so that 'Datatype' can use it
2013-05-25 wenzelm 2013-05-25 syntax translations always depend on context;
2013-04-10 wenzelm 2013-04-10 tuned pretty layout: avoid nested Pretty.string_of, which merely happens to work with Isabelle/jEdit since formatting is delegated to Scala side; declare command "print_case_translations" where it is actually defined;
2013-04-06 traytel 2013-04-06 disallow coercions to interfere with case translations
2013-04-05 traytel 2013-04-05 allow redundant cases in the list comprehension translation
2013-04-05 traytel 2013-04-05 special constant to prevent eta-contraction of the check-phase syntax of case translations
2013-01-22 traytel 2013-01-22 separate data used for case translation from the datatype package

2011-12-28 wenzelm 2011-12-28 reverted some changes for set->predicate transition, according to "hg log -u berghofe -r Isabelle2007:Isabelle2008"; tuned proofs;
2011-12-17 wenzelm 2011-12-17 clarified modules that contribute to datatype package;
2011-12-16 wenzelm 2011-12-16 prefer Name.context operations;

2011-09-10 haftmann 2011-09-10 renamed theory Complete_Lattice to Complete_Lattices, in accordance with Lattices, Orderings etc.
2011-06-27 krauss 2011-06-27 new Datatype.info_of_constr with strict behaviour wrt. to overloaded constructors -- side effect: function package correctly identifies 0::int as a non-constructor; renamed old version to info_of_constr_permissive, reflecting its semantics
2011-06-09 wenzelm 2011-06-09 discontinued Name.variant to emphasize that this is old-style / indirect;

2010-09-28 haftmann 2010-09-28 dropped old primrec package
2010-06-10 haftmann 2010-06-10 moved inductive_codegen to place where product type is available; tuned structure name
2010-02-11 wenzelm 2010-02-11 modernized translations; formal markup of @{syntax_const} and @{const_syntax}; minor tuning;
2009-11-30 haftmann 2009-11-30 modernized structures and tuned headers of datatype package modules; joined former datatype.ML and datatype_rep_proofs.ML
2009-11-30 haftmann 2009-11-30 merged
2009-11-27 haftmann 2009-11-27 renamed former datatype.ML to datatype_data.ML; datatype.ML provides uniform view on datatype.ML and datatype_rep_proofs.ML
2009-11-25 haftmann 2009-11-25 bootstrap datatype_rep_proofs in Datatype.thy (avoids unchecked dynamic name references)
2009-11-27 berghofe 2009-11-27 Streamlined setup for monotonicity rules (no longer requires classical rules).
2009-09-23 haftmann 2009-09-23 merged
2009-09-19 haftmann 2009-09-19 inter and union are mere abbreviations for inf and sup
