* Simplified outer syntax: uniform category "name" includes long 
20 
identifiers. Former "xname" / "nameref" / "name reference" has been 

21 
discontinued. 

22 

62807  23 
* Mixfix annotations support general block properties, with syntax 
24 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

25 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

26 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

27 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  28 

62440  29 
* New symbol \<circle>, e.g. for temporal operator. 
30 

62453  31 
* Old 'header' command is no longer supported (legacy since 
32 
Isabelle2015).

62440  34 

62904  35 
*** Prover IDE  Isabelle/Scala/jEdit *** 
36 

63022  37 
* IDE support for the Isabelle/Pure bootstrap process, with the 
38 
following independent stages: 

39 

40 
src/Pure/ROOT0.ML 

41 
src/Pure/ROOT.ML 

42 
src/Pure/Pure.thy 

43 
src/Pure/ML_Bootstrap.thy 

44 

45 
The ML ROOT files act like quasitheories in the context of theory 

46 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

47 
The theory files are presented with a modified header to import Pure 

48 
from the running Isabelle instance. Results from changed versions of 

49 
each stage are *not* propagated to the next stage, and isolated from the 

50 
actual Isabelle/Pure that runs the IDE itself. The sequential 

51 
dependencies of the above files are only relevant for batch build.

63039  62 
* Command 'define' introduces a local (nonpolymorphic) definition, with 
63 
optional abstraction over local parameters. The syntax resembles 

63043  64 
'definition' and 'obtain'. It fits better into the Isar language than 
65 
old 'def', which is now a legacy feature.

62216  76 

62327  77 
*** HOL *** 
78 

62522  79 
* New abbreviations for negated existence (but not bounded existence): 
80 

81 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

82 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

83 

62521  84 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
85 
has been removed for output. It is retained for input only, until it is 

86 
eliminated altogether. 

87 

62327  88 
* (Co)datatype package: 
62693  89 
 New commands for defining corecursive functions and reasoning about 
90 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive', 

91 
'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof 

62842  92 
method. See 'isabelle doc corec'. 
62693  93 
 The predicator :: ('a => bool) => 'a F => bool is now a firstclass 
62332  94 
citizen in bounded natural functors 
62693  95 
 'primrec' now allows nested calls through the predicator in addition 
62327  96 
to the map function. 
62693  97 
 'bnf' automatically discharges reflexive proof obligations 
98 
 'bnf' outputs a slightly modified proof obligation expressing rel in 

62332  99 
terms of map and set 
100 
(not giving a specification for rel makes this one reflexive) 

62693  101 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
62332  102 
(not giving a specification for pred makes this one reflexive) 
62693  103 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment 
62335  104 
 Renamed lemmas: 
105 
rel_prod_apply ~> rel_prod_inject 

106

111 
resemble the f.split naming convention, INCOMPATIBILITY. 

62396  112 

62597  113 
* Characters (type char) are modelled as finite algebraic type 
114 
corresponding to {0..255}. 

115 

116 
 Logical representation: 

117 
* 0 is instantiated to the ASCII zero character.

127 
with XX being the hexadecimal character code. "CHR n" 

62597  128 
is parsable for every numeral expression n. 
62598  129 
* Noncanonical characters have no special syntax and are 
62597  130

131 
 Explicit conversions from and to the natural numbers are 

132 
provided as char_of_nat, nat_of_char (as before).

429 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

430 
'SML_file_no_debug' control compilation of sources with or without 

431 
debugging information. The Debugger panel allows to set breakpoints (via 

432 
context menu), step through stopped threads, evaluate local ML 

433 
expressions etc. At least one Debugger view needs to be active to have 

434

* The text overview column (status of errors, warnings etc.) is updated

447 
full document node content is taken into account. The width of the 

448

449 
visibility. 

450 

451 
* The main text area no longer changes its color hue in outdated 

452 
situations. The text overview column takes over the role to indicate 

453 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

454

455

575 

60449  576 
The local assumptions are bound to the name "that". The result is 
577

60414  578 
corresponds to a raw proof block like this:

589 

61733  590 
* Assumptions ('assume', 'presume') allow structured rule statements 
591 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  592 

593 
assume result: "C x y" 

594 
if "A x" and "B y" 

595 
for x :: 'a and y :: 'a 

596 

597 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

598 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

599 

600 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

601 
only effects propositions according to actual use of variables. For 

602 
example: 

603 

604 
assume "A x" and "B y" for x and y 

605 

606 
is equivalent to: 

607 

608 
assume "\<And>x. A x" and "\<And>y. B y" 

609 

60595  610 
* The meaning of 'show' with Pure rule statements has changed: premises 
611 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  612 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
613 
follows: 

60595  614 

615 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

616 

617 
or: 

618 

619 
show "C x" if "A x" "B x" for x 

620 

621 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

622 

623 
show "C x" when "A x" "B x" for x 

624 

60459  625 
* New command 'consider' states rules for generalized elimination and 
626 
case splitting. This is like a toplevel statement "theorem obtains" used 

627 
within a proof body; or like a multibranch 'obtain' without activation 

628 
of the local context elements yet. 

629 

60455  630 
* Proof method "cases" allows to specify the rule as first entry of 
631 
chained facts. This is particularly useful with 'consider': 

632 

633 
consider (a) A  (b) B  (c) C <proof> 

634 
then have something 

635 
proof cases 

636 
case a 

637 
then show ?thesis <proof> 

638 
next 

639 
case b 

640 
then show ?thesis <proof> 

641 
next 

642 
case c 

643 
then show ?thesis <proof> 

644 
qed 

645 

60565  646 
* Command 'case' allows fact name and attribute specification like this: 
647 

648 
case a: (c xs) 

649 
case a [attributes]: (c xs) 

650 

651 
Facts that are introduced by invoking the case context are uniformly 

652 
qualified by "a"; the same name is used for the cumulative fact. The old 

653 
form "case (c xs) [attributes]" is no longer supported. Rare 

654 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

655 
and always put attributes in front.

'abbreviation' is also kept for morphims that only change the involved

* The 'typedef' command has been upgraded from a partially checked 
786 
"axiomatization", to a full definitional specification that takes the 

787 
global collection of overloaded constant / type definitions into 

788 
account. Type definitions with open dependencies on overloaded 

789 
definitions need to be specified as "typedef (overloaded)". This 

790 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

791 

792 
* Qualification of various formal entities in the libraries is done more 

793 
uniformly via "context begin qualified definition ... end" instead of 

794 
oldstyle "hide_const (open) ...". Consequently, both the defined 

795 
constant and its defining fact become qualified, e.g. Option.is_none and 

796 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

797 

798 
* Some old and rarely used ASCII replacement syntax has been removed. 

799 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

800

801 
simplify porting old theories: 

802

804

826 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

827 

828 
* The alternative notation "\<Colon>" for type and sort constraints has been 

829 
removed: in LaTeX document output it looks the same as "::". 

830 
INCOMPATIBILITY, use plain "::" instead. 

831 

832 
* Commands 'inductive' and 'inductive_set' work better when names for 

833 
intro rules are omitted: the "cases" and "induct" rules no longer 

834 
declare empty case_names, but no case_names at all. This allows to use 

835 
numbered cases in proofs, without requiring method "goal_cases". 

836 

837 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

838 
lowlevel facts of the internal construction only if the option 

62093  839 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  840 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
841 

842 
* Recursive function definitions ('fun', 'function', 'partial_function') 

843 
expose lowlevel facts of the internal construction only if the option 

62205  844 
"function_internals" is enabled. Its internal inductive definition is 
845 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  846 

847 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

848 
of the internal construction only if the option "bnf_internals" is 

849 
enabled. This supersedes the former option "bnf_note_all". Rare 

850 
INCOMPATIBILITY. 

62017  851 

852 
* Combinator to represent case distinction on products is named 

853 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

854 
theorem aliasses have been retained.

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

902 
'real' is no longer overloaded, but has type 'nat => real' and 

903 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

904 
abbreviates of_int for that type. Other overloaded instances of 'real' 

905 
have been replaced by 'real_of_ereal' and 'real_of_float'.

*** ML ***

62017  1101 
* The following combinators for lowlevel profiling of the ML runtime 
1102 
system are available: 

1103 

1104 
profile_time (*CPU time*) 

1105 
profile_time_thread (*CPU time on this thread*) 

1106 
profile_allocations (*overall heap allocations*) 

1107 

1108 
* Antiquotation @{undefined} or \<^undefined> inlines (raise Match). 

1109 

62075  1110 
* Antiquotation @{method NAME} inlines the (checked) name of the given 
1111 
Isar proof method. 

1112 

61922  1113 
* Pretty printing of Poly/ML compiler output in Isabelle has been 
1114 
improved: proper treatment of break offsets and blocks with consistent 

1115 
breaks. 

1116 

61268  1117 
* The auxiliary module Pure/display.ML has been eliminated. Its 
1118 
elementary thm print operations are now in Pure/more_thm.ML and thus 

1119 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY. 

1120 

61144  1121 
* Simproc programming interfaces have been simplified: 
1122 
Simplifier.make_simproc and Simplifier.define_simproc supersede various 

1123 
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that 

1124 
term patterns for the lefthand sides are specified with implicitly 

1125 
fixed variables, like toplevel theorem statements. INCOMPATIBILITY. 

1126 

60802  1127 
* Instantiation rules have been reorganized as follows: 
1128 

1129 
Thm.instantiate (*lowlevel instantiation with named arguments*) 

1130 
Thm.instantiate' (*version with positional arguments*) 

1131 

1132 
Drule.infer_instantiate (*instantiation with type inference*) 

1133 
Drule.infer_instantiate' (*version with positional arguments*) 

1134 

1135 
The LHS only requires variable specifications, instead of full terms. 

1136 
Old cterm_instantiate is superseded by infer_instantiate. 

1137 
INCOMPATIBILITY, need to readjust some ML names and types accordingly. 

1138 

60793  1139 
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been 
1140 
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc. 

1141 
instead (with proper context).

1243 
together with an attribute to maintain the content incrementally. This 

1244 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1309 
context, even before the initial 'theory' command. Obsolete proof 

1310 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1311 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1312 
instead. The old 'header' command is still retained for some time, but 

1313 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1314 
update_header"). Minor INCOMPATIBILITY. 

1315 

60009  1316 
* Official support for "tt" style variants, via \isatt{...} or 
1317 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1318 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1319 
as argument to other macros (such as footnotes). 

1320 

1321 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1322 
style. 

1323 

1324 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1325 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1326

1329 
to proof document structure, and no longer "stick out" accidentally. 

1330 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1331 
tags. Potential INCOMPATIBILITY in exotic situations.

* System option "pretty_margin" is superseded by "thy_output_margin", 

1334 
which is also accessible via document antiquotation option "margin". 

1335 
Only the margin for document output may be changed, but not the global 

1336 
pretty printing: that is 76 for plain console output, and adapted 

1337 
dynamically in GUI frontends. Implementations of document 

1338 
antiquotations need to observe the margin explicitly according to 

1339 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
