* 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is superseded by "(\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).

40 

63135  41 
* Cartouche abbreviations work both for " and ` to accomodate typical 
42 
situations where old ASCII notation may be updated. 

43 

63022  44 
* IDE support for the Isabelle/Pure bootstrap process, with the 
45 
following independent stages: 

46 

47 
src/Pure/ROOT0.ML 

48 
src/Pure/ROOT.ML 

49 
src/Pure/Pure.thy 

50 
src/Pure/ML_Bootstrap.thy 

51 

52 
The ML ROOT files act like quasitheories in the context of theory 

53 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

54 
The theory files are presented with a modified header to import Pure 

55 
from the running Isabelle instance. Results from changed versions of 

56 
each stage are *not* propagated to the next stage, and isolated from the 

57 
actual Isabelle/Pure that runs the IDE itself. The sequential 

58 
dependencies of the above files are only relevant for batch build.

* Command 'define' introduces a local (nonpolymorphic) definition, with 
88 
optional abstraction over local parameters. The syntax resembles 

63043  89 
'definition' and 'obtain'. It fits better into the Isar language than 
90 
old 'def', which is now a legacy feature.

99 
Isabelle2016). INCOMPATIBILITY, use "standard" instead. 

100 

63259  101 
* Proof methods may refer to the main facts via the dynamic fact 
102 
"method_facts". This is particularly useful for Eisbach method 

103 
definitions. 

104 

105 
* Eisbach provides method "use" to modify the main facts of a given 

106 
method expression, e.g. 

107 

108 
(use facts in simp) 

109 
(use facts in \<open>simp add: ...\<close>)

529 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

530 
'SML_file_no_debug' control compilation of sources with or without 

531 
debugging information. The Debugger panel allows to set breakpoints (via 

532 
context menu), step through stopped threads, evaluate local ML 

533 
expressions etc. At least one Debugger view needs to be active to have 

534 
any effect on the running ML program. 

60984  535

* The State panel manages explicit proof state output, with dynamic 
537

538 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

539 
update. 

61729  540 

541 
* The Output panel no longer shows proof state output by default, to 

542 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

543 
enable option "editor_output_state". 

61215  544 

61803  545 
* The text overview column (status of errors, warnings etc.) is updated 
546 
asynchronously, leading to much better editor reactivity. Moreover, the 

547 
full document node content is taken into account. The width of the 

548 
column is scaled according to the main text area font, for improved 

549 
visibility. 

550 

551 
* The main text area no longer changes its color hue in outdated 

552 
situations. The text overview column takes over the role to indicate 

553 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

554 
due to adhoc updates by auxiliary GUI components, such as the State 

555 
panel.

675 

60449  676 
The local assumptions are bound to the name "that". The result is 
677 
exported from context of the statement as usual. The above roughly 

60414  678 
corresponds to a raw proof block like this: 
679

* Assumptions ('assume', 'presume') allow structured rule statements 
691 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  692 

693 
assume result: "C x y" 

694 
if "A x" and "B y" 

695 
for x :: 'a and y :: 'a 

696 

697 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

698 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

699 

700 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

701 
only effects propositions according to actual use of variables. For 

702 
example: 

703 

704 
assume "A x" and "B y" for x and y 

705 

706 
is equivalent to: 

707 

708 
assume "\<And>x. A x" and "\<And>y. B y" 

709 

60595  710 
* The meaning of 'show' with Pure rule statements has changed: premises 
711 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  712 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
713 
follows: 

60595  714 

715 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

716 

717 
or: 

718 

719 
show "C x" if "A x" "B x" for x 

720 

721 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

722 

723 
show "C x" when "A x" "B x" for x 

724 

60459  725 
* New command 'consider' states rules for generalized elimination and 
726 
case splitting. This is like a toplevel statement "theorem obtains" used 

727 
within a proof body; or like a multibranch 'obtain' without activation 

728 
of the local context elements yet. 

729 

60455  730 
* Proof method "cases" allows to specify the rule as first entry of 
731 
chained facts. This is particularly useful with 'consider': 

732 

733 
consider (a) A  (b) B  (c) C <proof> 

734 
then have something 

735 
proof cases 

736

737

738

745 

60565  746 
* Command 'case' allows fact name and attribute specification like this: 
747 

748 
case a: (c xs) 

749 
case a [attributes]: (c xs) 

750 

751 
Facts that are introduced by invoking the case context are uniformly 

752 
qualified by "a"; the same name is used for the cumulative fact. The old 

753 
form "case (c xs) [attributes]" is no longer supported. Rare 

754 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

755 
and always put attributes in front.

765 
relevant for 'using', 'including', 'supply':

1002 
'real' is no longer overloaded, but has type 'nat => real' and

1004 
abbreviates of_int for that type. Other overloaded instances of 'real' 

1005

* Class algebraic_semidom introduces common algebraic notions of 
62017  1082 
integral (semi)domains, particularly units. Although logically subsumed 
1083 
by fields, is is not a super class of these in order not to burden 

1084 
fields with notions that are trivial there. 

1085 

1086 
* Class normalization_semidom specifies canonical representants for 

1087 
equivalence classes of associated elements in an integral (semi)domain. 

1088 
This formalizes associated elements as well.

* Abstract specification of gcd/lcm operations in classes semiring_gcd, 
62017  1091 
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute 
1092 
and gcd_int.commute are subsumed by gcd.commute, as well as 

1093 
gcd_nat.assoc and gcd_int.assoc by gcd.assoc. 

1094 

1095 
* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are 

1096 
logically unified to Rings.divide in syntactic type class Rings.divide, 

1097 
with infix syntax (_ div _). Infix syntax (_ / _) for field division is 

1098 
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY, 

1099 
instantiations must refer to Rings.divide rather than the former 

1100

1101 
during instantiation.

* Command 'experiment' opens an anonymous locale context with private 
1336 
naming policy. 

1337 

59951  1338 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1339 
structure in the body: 'oops' is no longer supported here. Minor 

1340 
INCOMPATIBILITY, use 'sorry' instead. 

1341 

1342 
* Command 'named_theorems' declares a dynamic fact within the context, 

1343 
together with an attribute to maintain the content incrementally. This 

1344 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1345 
of semantics due to external visual order vs. internal reverse order. 

1346 

1347 
* 'find_theorems': search patterns which are abstractions are 

1348 
schematically expanded before search. Search results match the naive 

1349 
expectation more closely, particularly wrt. abbreviations. 

1350 
INCOMPATIBILITY.

* Improved folding mode "isabelle" based on Isar syntax. Alternatively, 
1379 
the "sidekick" mode may be used for document structure.
