* 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is superseded by "(\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).

*** 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.

'definition' and 'obtain'. It fits better into the Isar language than

*** HOL *** 
88 

62522  89 
* New abbreviations for negated existence (but not bounded existence): 
90 

91 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

92 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

93 

62521  94 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
95 
has been removed for output. It is retained for input only, until it is 

96 
eliminated altogether. 

97

 New commands for defining corecursive functions and reasoning about 
100 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive',

62693  103 
 The predicator :: ('a => bool) => 'a F => bool is now a firstclass 
62332  104 
citizen in bounded natural functors 
62693  105 
 'primrec' now allows nested calls through the predicator in addition 
62327  106 
to the map function. 
62693  107 
 'bnf' automatically discharges reflexive proof obligations 
108 
 'bnf' outputs a slightly modified proof obligation expressing rel in 

62332  109 
terms of map and set 
110 
(not giving a specification for rel makes this one reflexive) 

62693  111 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
62332  112 
(not giving a specification for pred makes this one reflexive) 
62693  113 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment 
62335  114

121 
linorder_cases instead. 

122 

62407  123 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
124

62396  125

446 
'SML_file_no_debug' control compilation of sources with or without 

447

448

* The text overview column (status of errors, warnings etc.) is updated 
462 
asynchronously, leading to much better editor reactivity. Moreover, the 

463 
full document node content is taken into account. The width of the 

464 
column is scaled according to the main text area font, for improved 

465 
visibility. 

466 

467 
* The main text area no longer changes its color hue in outdated 

468 
situations. The text overview column takes over the role to indicate 

469 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

470 
due to adhoc updates by auxiliary GUI components, such as the State 

471

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

* Assumptions ('assume', 'presume') allow structured rule statements 
607 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  608 

609 
assume result: "C x y" 

610 
if "A x" and "B y" 

611 
for x :: 'a and y :: 'a 

612 

613 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

614 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

615 

616 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

617 
only effects propositions according to actual use of variables. For 

618 
example: 

619 

620 
assume "A x" and "B y" for x and y 

621 

622 
is equivalent to: 

623 

624 
assume "\<And>x. A x" and "\<And>y. B y" 

625 

60595  626 
* The meaning of 'show' with Pure rule statements has changed: premises 
627 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  628 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
629 
follows: 

60595  630 

631 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

632 

633 
or: 

634 

635 
show "C x" if "A x" "B x" for x 

636 

637 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

638 

639 
show "C x" when "A x" "B x" for x 

640 

60459  641 
* New command 'consider' states rules for generalized elimination and 
642 
case splitting. This is like a toplevel statement "theorem obtains" used 

643

* Proof method "cases" allows to specify the rule as first entry of

663 

664 
case a: (c xs) 

665 
case a [attributes]: (c xs) 

666 

667 
Facts that are introduced by invoking the case context are uniformly 

668 
qualified by "a"; the same name is used for the cumulative fact. The old 

669 
form "case (c xs) [attributes]" is no longer supported. Rare

* The 'typedef' command has been upgraded from a partially checked 
802 
"axiomatization", to a full definitional specification that takes the 

803 
global collection of overloaded constant / type definitions into 

804 
account. Type definitions with open dependencies on overloaded 

805 
definitions need to be specified as "typedef (overloaded)". This 

806 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

807 

808 
* Qualification of various formal entities in the libraries is done more 

809 
uniformly via "context begin qualified definition ... end" instead of 

810 
oldstyle "hide_const (open) ...". Consequently, both the defined 

811 
constant and its defining fact become qualified, e.g. Option.is_none and 

812 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

843 

844 
* The alternative notation "\<Colon>" for type and sort constraints has been 

845 
removed: in LaTeX document output it looks the same as "::". 

846 
INCOMPATIBILITY, use plain "::" instead. 

847 

848 
* Commands 'inductive' and 'inductive_set' work better when names for 

849 
intro rules are omitted: the "cases" and "induct" rules no longer 

850 
declare empty case_names, but no case_names at all. This allows to use 

851 
numbered cases in proofs, without requiring method "goal_cases". 

852 

853 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

854 
lowlevel facts of the internal construction only if the option 

62093  855 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  856 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
857 

858 
* Recursive function definitions ('fun', 'function', 'partial_function') 

859 
expose lowlevel facts of the internal construction only if the option 

62205  860 
"function_internals" is enabled. Its internal inductive definition is 
861 
also subject to "inductive_internals". Rare INCOMPATIBILITY.

863 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

864 
of the internal construction only if the option "bnf_internals" is 

865 
enabled. This supersedes the former option "bnf_note_all". Rare

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

918 
'real' is no longer overloaded, but has type 'nat => real' and 

919 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

920 
abbreviates of_int for that type. Other overloaded instances of 'real' 

921 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* The following combinators for lowlevel profiling of the ML runtime 
1118 
system are available: 

1119 

1120 
profile_time (*CPU time*) 

1121 
profile_time_thread (*CPU time on this thread*)

* Pretty printing of Poly/ML compiler output in Isabelle has been 
1130 
improved: proper treatment of break offsets and blocks with consistent 

1131

1132 

61268  1133 
* The auxiliary module Pure/display.ML has been eliminated. Its 
1134 
elementary thm print operations are now in Pure/more_thm.ML and thus 

1135 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.

1140

Drule.infer_instantiate (*instantiation with type inference*) 

1149 
Drule.infer_instantiate' (*version with positional arguments*) 

1150 

1151 
The LHS only requires variable specifications, instead of full terms. 

1152 
Old cterm_instantiate is superseded by infer_instantiate. 

1153 
INCOMPATIBILITY, need to readjust some ML names and types accordingly. 

1154 

60793  1155

*** Document preparation *** 
1322 

1323 
* Document markup commands 'chapter', 'section', 'subsection', 

1324 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1325 
context, even before the initial 'theory' command. Obsolete proof 

1326 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1327 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1328 
instead. The old 'header' command is still retained for some time, but 

1329 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1330 
update_header"). Minor INCOMPATIBILITY. 

1331 

60009  1332 
* Official support for "tt" style variants, via \isatt{...} or 
1333 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1334 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1335 
as argument to other macros (such as footnotes). 

1336 

1337 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1338 
style. 

1339 

1340 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1341 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1342 

59951  1343 
* Diagnostic commands and document markup commands within a proof do not 
1344 
affect the command tag for output. Thus commands like 'thm' are subject 

1345 
to proof document structure, and no longer "stick out" accidentally. 

1346 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1347 
tags. Potential INCOMPATIBILITY in exotic situations. 

1348 

1349 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1350 
which is also accessible via document antiquotation option "margin". 

1351 
Only the margin for document output may be changed, but not the global 

1352 
pretty printing: that is 76 for plain console output, and adapted 

1353 
dynamically in GUI frontends. Implementations of document 

1354 
antiquotations need to observe the margin explicitly according to 

1355 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
