* Simplified outer syntax: uniform category "name" includes long 
24 
identifiers. Former "xname" / "nameref" / "name reference" has been 

25 
discontinued. 

26 

62807  27 
* Mixfix annotations support general block properties, with syntax 
28 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

29 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

30 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

31 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  32 

62440  33 
* New symbol \<circle>, e.g. for temporal operator. 
34 

62453  35 
* Old 'header' command is no longer supported (legacy since 
36 
Isabelle2015). 

37 

63273  38 
* Command 'bundle' provides a local theory target to define a bundle 
39 
from the body of specification commands (such as 'declare', 

40 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

41 

42 
bundle foo 

43 
begin 

44 
declare a [simp] 

45 
declare b [intro] 

46 
end

*** Prover IDE  Isabelle/Scala/jEdit *** 
50 

63135  51 
* Cartouche abbreviations work both for " and ` to accomodate typical 
52 
situations where old ASCII notation may be updated. 

53 

63022  54 
* IDE support for the Isabelle/Pure bootstrap process, with the 
55 
following independent stages: 

56 

57 
src/Pure/ROOT0.ML 

58 
src/Pure/ROOT.ML 

59 
src/Pure/Pure.thy 

60 
src/Pure/ML_Bootstrap.thy 

61 

62 
The ML ROOT files act like quasitheories in the context of theory 

63 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

64 
The theory files are presented with a modified header to import Pure 

65 
from the running Isabelle instance. Results from changed versions of 

66 
each stage are *not* propagated to the next stage, and isolated from the 

67 
actual Isabelle/Pure that runs the IDE itself. The sequential 

68 
dependencies of the above files are only relevant for batch build.

optional abstraction over local parameters. The syntax resembles

'definition' and 'obtain'. It fits better into the Isar language than 
100 
old 'def', which is now a legacy feature.

Isabelle2016). INCOMPATIBILITY, use "standard" instead. 

110 

63259  111 
* Proof methods may refer to the main facts via the dynamic fact 
112 
"method_facts". This is particularly useful for Eisbach method 

113 
definitions. 

114 

115 
* Eisbach provides method "use" to modify the main facts of a given 

116 
method expression, e.g. 

117 

118 
(use facts in simp) 

119 
(use facts in \<open>simp add: ...\<close>)

'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

542 
'SML_file_no_debug' control compilation of sources with or without 

543

544

action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

551

61215  556

* The text overview column (status of errors, warnings etc.) is updated 
558 
asynchronously, leading to much better editor reactivity. Moreover, the 

559 
full document node content is taken into account. The width of the 

560 
column is scaled according to the main text area font, for improved 

561 
visibility. 

562 

563 
* The main text area no longer changes its color hue in outdated 

564 
situations. The text overview column takes over the role to indicate 

565 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

566 
due to adhoc updates by auxiliary GUI components, such as the State 

567 
panel.

The local assumptions are bound to the name "that". The result is

corresponds to a raw proof block like this:

* Assumptions ('assume', 'presume') allow structured rule statements 
703 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  704 

705 
assume result: "C x y" 

706 
if "A x" and "B y" 

707 
for x :: 'a and y :: 'a 

708 

709 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

710 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

711 

712 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

713 
only effects propositions according to actual use of variables. For 

714 
example: 

715 

716 
assume "A x" and "B y" for x and y 

717 

718 
is equivalent to: 

719 

720 
assume "\<And>x. A x" and "\<And>y. B y" 

721 

60595  722 
* The meaning of 'show' with Pure rule statements has changed: premises 
723 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  724 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
725 
follows: 

60595  726 

727 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

728 

729 
or: 

730 

731 
show "C x" if "A x" "B x" for x 

732 

733 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

734 

735 
show "C x" when "A x" "B x" for x 

736 

60459  737 
* New command 'consider' states rules for generalized elimination and 
738 
case splitting. This is like a toplevel statement "theorem obtains" used 

739 
within a proof body; or like a multibranch 'obtain' without activation 

740 
of the local context elements yet. 

741 

60455  742 
* Proof method "cases" allows to specify the rule as first entry of 
743 
chained facts. This is particularly useful with 'consider': 

744 

745 
consider (a) A  (b) B  (c) C <proof> 

746 
then have something 

747 
proof cases 

748

749

757 

60565  758 
* Command 'case' allows fact name and attribute specification like this: 
759 

760 
case a: (c xs) 

761 
case a [attributes]: (c xs) 

762 

763 
Facts that are introduced by invoking the case context are uniformly 

764 
qualified by "a"; the same name is used for the cumulative fact. The old 

765 
form "case (c xs) [attributes]" is no longer supported. Rare 

766 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

767 
and always put attributes in front.

INCOMPATIBILITY, standard syntax with symbols should be used instead. 

912 
The subsequent commands help to reproduce the old forms, e.g. to 

913 
simplify porting old theories: 

914 

915 
notation iff (infixr "<>" 25) 

916 

917 
notation Times (infixr "<*>" 80) 

918 

919 
type_notation Map.map (infixr "~=>" 0) 

920 
notation Map.map_comp (infixl "o'_m" 55) 

921 

922 
type_notation FinFun.finfun ("(_ =>f /_)" [22, 21] 21) 

923 

924 
notation FuncSet.funcset (infixr ">" 60) 

925 
notation FuncSet.extensional_funcset (infixr ">\<^sub>E" 60) 

926 

927 
notation Omega_Words_Fun.conc (infixr "conc" 65) 

928 

929 
notation Preorder.equiv ("op ~~") 

930 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

931 

932 
notation (in topological_space) tendsto (infixr ">" 55) 

933 
notation (in topological_space) LIMSEQ ("((_)/ > (_))" [60, 60] 60) 

934 
notation LIM ("((_)/  (_)/ > (_))" [60, 0, 60] 60) 

935 

936 
notation NSA.approx (infixl "@=" 50) 

937 
notation NSLIMSEQ ("((_)/ NS> (_))" [60, 60] 60) 

938 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

939 

940 
* The alternative notation "\<Colon>" for type and sort constraints has been 

941 
removed: in LaTeX document output it looks the same as "::". 

942 
INCOMPATIBILITY, use plain "::" instead. 

943 

944 
* Commands 'inductive' and 'inductive_set' work better when names for 

945 
intro rules are omitted: the "cases" and "induct" rules no longer 

946 
declare empty case_names, but no case_names at all. This allows to use 

947 
numbered cases in proofs, without requiring method "goal_cases". 

948 

949 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

950 
lowlevel facts of the internal construction only if the option 

62093  951 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  952 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
953 

954 
* Recursive function definitions ('fun', 'function', 'partial_function') 

955 
expose lowlevel facts of the internal construction only if the option 

62205  956 
"function_internals" is enabled. Its internal inductive definition is 
957 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  958 

959 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

960 
of the internal construction only if the option "bnf_internals" is 

961 
enabled. This supersedes the former option "bnf_note_all". Rare 

962 
INCOMPATIBILITY. 

62017  963 

964 
* Combinator to represent case distinction on products is named 

965 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

966 
theorem aliasses have been retained.

* The coercions to type 'real' have been reorganised. The function 

1014 
'real' is no longer overloaded, but has type 'nat => real' and 

1015 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

1016 
abbreviates of_int for that type. Other overloaded instances of 'real' 

1017 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* Class algebraic_semidom introduces common algebraic notions of 
62017  1094 
integral (semi)domains, particularly units. Although logically subsumed 
1095 
by fields, is is not a super class of these in order not to burden 

1096 
fields with notions that are trivial there. 

1097 

1098 
* Class normalization_semidom specifies canonical representants for 

1099 
equivalence classes of associated elements in an integral (semi)domain.

* Abstract specification of gcd/lcm operations in classes semiring_gcd,

1104

* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are 

1108 
logically unified to Rings.divide in syntactic type class Rings.divide, 

1109 
with infix syntax (_ div _). Infix syntax (_ / _) for field division is 

1110 
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY, 

1111 
instantiations must refer to Rings.divide rather than the former

62205  1313 
64bit via system option ML_system_64. A system restart (and rebuild) is 
1314 
required after change.

* Poly/ML 5.6 runs natively on x86windows and x86_64windows, which 

1317 
both allow larger heap space than former x86cygwin. 

1318 

62157  1319 
* Heap images are 1015% smaller due to less wasteful persistent theory 
1320 
content (using ML type theory_id instead of theory);

* Command 'experiment' opens an anonymous locale context with private 
1348 
naming policy. 

1349 

59951  1350 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1351 
structure in the body: 'oops' is no longer supported here. Minor 

1352 
INCOMPATIBILITY, use 'sorry' instead. 

1353 

1354 
* Command 'named_theorems' declares a dynamic fact within the context, 

1355 
together with an attribute to maintain the content incrementally. This 

1356 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1357 
of semantics due to external visual order vs. internal reverse order. 

1358 

1359 
* 'find_theorems': search patterns which are abstractions are 

1360 
schematically expanded before search. Search results match the naive 

1361 
expectation more closely, particularly wrt. abbreviations.

INCOMPATIBILITY.
