62969  23 
* 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is superseded by "(\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 

63272  38 
* Command 'bundle_definition' provides a local theory target to define a 
39 
bundle from the body of specification commands (e.g. 'declare', 

40 
'declaration', 'notation', 'lemmas', 'lemma').

*** Prover IDE  Isabelle/Scala/jEdit *** 
44 

63135  45 
* Cartouche abbreviations work both for " and ` to accomodate typical 
46 
situations where old ASCII notation may be updated. 

47 

63022  48 
* IDE support for the Isabelle/Pure bootstrap process, with the 
49 
following independent stages: 

50 

51 
src/Pure/ROOT0.ML 

52 
src/Pure/ROOT.ML 

53 
src/Pure/Pure.thy 

54 
src/Pure/ML_Bootstrap.thy 

55 

56 
The ML ROOT files act like quasitheories in the context of theory 

57 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

58 
The theory files are presented with a modified header to import Pure 

59 
from the running Isabelle instance. Results from changed versions of 

60 
each stage are *not* propagated to the next stage, and isolated from the 

61 
actual Isabelle/Pure that runs the IDE itself. The sequential 

62 
dependencies of the above files are only relevant for batch build.

68

* Command 'define' introduces a local (nonpolymorphic) definition, with 
92 
optional abstraction over local parameters. The syntax resembles 

63043  93 
'definition' and 'obtain'. It fits better into the Isar language than 
94 
old 'def', which is now a legacy feature.

103 
Isabelle2016). INCOMPATIBILITY, use "standard" instead. 

104 

63259  105 
* Proof methods may refer to the main facts via the dynamic fact 
106 
"method_facts". This is particularly useful for Eisbach method 

107 
definitions. 

108 

109 
* Eisbach provides method "use" to modify the main facts of a given 

110 
method expression, e.g. 

111 

112 
(use facts in simp) 

113 
(use facts in \<open>simp add: ...\<close>)

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

536 
'SML_file_no_debug' control compilation of sources with or without 

537 
debugging information. The Debugger panel allows to set breakpoints (via 

538

539 
expressions etc. At least one Debugger view needs to be active to have 

540

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

545 
update.

547

548 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

549

61215  550

* The text overview column (status of errors, warnings etc.) is updated 
552 
asynchronously, leading to much better editor reactivity. Moreover, the 

553 
full document node content is taken into account. The width of the 

554 
column is scaled according to the main text area font, for improved 

555 
visibility. 

556 

557 
* The main text area no longer changes its color hue in outdated 

558 
situations. The text overview column takes over the role to indicate 

559 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

560 
due to adhoc updates by auxiliary GUI components, such as the State 

561 
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 
697 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  698 

699 
assume result: "C x y" 

700 
if "A x" and "B y" 

701 
for x :: 'a and y :: 'a 

702 

703 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

704 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

705 

706 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

707 
only effects propositions according to actual use of variables. For 

708 
example: 

709 

710 
assume "A x" and "B y" for x and y 

711 

712 
is equivalent to: 

713 

714 
assume "\<And>x. A x" and "\<And>y. B y" 

715 

60595  716 
* The meaning of 'show' with Pure rule statements has changed: premises 
717 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  718 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
719 
follows: 

60595  720 

721 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

722 

723 
or: 

724 

725 
show "C x" if "A x" "B x" for x 

726 

727 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

728 

729 
show "C x" when "A x" "B x" for x 

730 

60459  731 
* New command 'consider' states rules for generalized elimination and 
732 
case splitting. This is like a toplevel statement "theorem obtains" used 

733 
within a proof body; or like a multibranch 'obtain' without activation 

734 
of the local context elements yet. 

735 

60455  736 
* Proof method "cases" allows to specify the rule as first entry of 
737 
chained facts. This is particularly useful with 'consider': 

738 

739 
consider (a) A  (b) B  (c) C <proof> 

740 
then have something 

741

742

751 

60565  752 
* Command 'case' allows fact name and attribute specification like this: 
753 

754 
case a: (c xs) 

755 
case a [attributes]: (c xs) 

756 

757 
Facts that are introduced by invoking the case context are uniformly 

758 
qualified by "a"; the same name is used for the cumulative fact. The old 

759 
form "case (c xs) [attributes]" is no longer supported. Rare 

760 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

761 
and always put attributes in front.

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

1011 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* Class algebraic_semidom introduces common algebraic notions of 
62017  1088 
integral (semi)domains, particularly units. Although logically subsumed 
1089 
by fields, is is not a super class of these in order not to burden 

1090 
fields with notions that are trivial there. 

1091 

1092 
* Class normalization_semidom specifies canonical representants for 

1093 
equivalence classes of associated elements in an integral (semi)domain. 

1094 
This formalizes associated elements as well.

* Abstract specification of gcd/lcm operations in classes semiring_gcd, 
62017  1097 
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute 
1098 
and gcd_int.commute are subsumed by gcd.commute, as well as 

1099 
gcd_nat.assoc and gcd_int.assoc by gcd.assoc. 

1100 

1101 
* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are 

1102 
logically unified to Rings.divide in syntactic type class Rings.divide, 

1103 
with infix syntax (_ div _). Infix syntax (_ / _) for field division is 

1104 
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY, 

1105 
instantiations must refer to Rings.divide rather than the former 

1106 
separate constants, hence infix syntax (_ / _) is usually not available 

1107 
during instantiation.

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

1311 
both allow larger heap space than former x86cygwin. 

1312

* Heap images are 1015% smaller due to less wasteful persistent theory 
1314 
content (using ML type theory_id instead of theory);

* Command 'experiment' opens an anonymous locale context with private 
1342 
naming policy. 

1343 

59951  1344 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1345 
structure in the body: 'oops' is no longer supported here. Minor 

1346 
INCOMPATIBILITY, use 'sorry' instead. 

1347 

1348 
* Command 'named_theorems' declares a dynamic fact within the context, 

1349 
together with an attribute to maintain the content incrementally. This 

1350 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1351 
of semantics due to external visual order vs. internal reverse order. 

1352 

1353 
* 'find_theorems': search patterns which are abstractions are 

1354 
schematically expanded before search. Search results match the naive 

1355 
expectation more closely, particularly wrt. abbreviations.

INCOMPATIBILITY.
