New in this Isabelle version

62440  10 
*** General *** 
11 

62807  12 
* Mixfix annotations support general block properties, with syntax 
13 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

14 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

15 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

16 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  17 

62440  18 
* New symbol \<circle>, e.g. for temporal operator. 
19 

62453  20 
* Old 'header' command is no longer supported (legacy since 
21 
Isabelle2015). 

22 

62440  23 

62904  24 
*** Prover IDE  Isabelle/Scala/jEdit *** 
25 

26 
* IDE support for the Isabelle/Pure bootstrap process. The file 

27 
src/Pure/ROOT.ML may be opened with Isabelle/jEdit: it acts like a 

28 
theory body in the context of theory ML_Bootstrap. This allows 

29 
continuous checking of ML files as usual, but the result is isolated 

30 
from the actual Isabelle/Pure that runs the IDE itself.

typesetting. E.g. to produce proof holes in examples and documentation. 
62216  37 

38 

62327  39 
*** HOL *** 
40 

62522  41 
* New abbreviations for negated existence (but not bounded existence): 
42 

43 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

44 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

45 

62521  46 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
47 
has been removed for output. It is retained for input only, until it is 

48 
eliminated altogether. 

49 

62327  50 
* (Co)datatype package: 
62693  51 
 New commands for defining corecursive functions and reasoning about 
52 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive', 

53 
'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof 

62842  54 
method. See 'isabelle doc corec'. 
62693  55 
 The predicator :: ('a => bool) => 'a F => bool is now a firstclass 
62332  56 
citizen in bounded natural functors 
62693  57 
 'primrec' now allows nested calls through the predicator in addition 
62327  58 
to the map function. 
62693  59 
 'bnf' automatically discharges reflexive proof obligations 
60 
 'bnf' outputs a slightly modified proof obligation expressing rel in 

62332  61 
terms of map and set 
62 
(not giving a specification for rel makes this one reflexive) 

62693  63 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
62332  64 
(not giving a specification for pred makes this one reflexive) 
62693  65 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment 
62335  66 
 Renamed lemmas: 
67 
rel_prod_apply ~> rel_prod_inject 

68 
pred_prod_apply ~> pred_prod_inject 

69

62327  71 

62407  72 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
73 
resemble the f.split naming convention, INCOMPATIBILITY. 

62396  74 

62597  75 
* Characters (type char) are modelled as finite algebraic type 
76 
corresponding to {0..255}. 

77 

78 
 Logical representation: 

79 
* 0 is instantiated to the ASCII zero character.

89 
with XX being the hexadecimal character code. "CHR n" 

62597  90 
is parsable for every numeral expression n. 
62598  91 
* Noncanonical characters have no special syntax and are 
62597  92 
printed as their logical representation. 
93 
 Explicit conversions from and to the natural numbers are 

94 
provided as char_of_nat, nat_of_char (as before). 

95 
 The auxiliary nibble type has been discontinued.

386 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

387 
'SML_file_no_debug' control compilation of sources with or without 

388 
debugging information. The Debugger panel allows to set breakpoints (via 

389

390

391

* The text overview column (status of errors, warnings etc.) is updated 
403 
asynchronously, leading to much better editor reactivity. Moreover, the 

404 
full document node content is taken into account. The width of the 

405 
column is scaled according to the main text area font, for improved 

406 
visibility. 

407 

408 
* The main text area no longer changes its color hue in outdated 

409 
situations. The text overview column takes over the role to indicate 

410 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

411 
due to adhoc updates by auxiliary GUI components, such as the State 

412 
panel.

60449  533 
The local assumptions are bound to the name "that". The result is 
534 
exported from context of the statement as usual. The above roughly 

60414  535 
corresponds to a raw proof block like this:

546 

61733  547 
* Assumptions ('assume', 'presume') allow structured rule statements 
548 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  549 

550 
assume result: "C x y" 

551 
if "A x" and "B y" 

552 
for x :: 'a and y :: 'a 

553 

554 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

555 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

556 

557 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

558 
only effects propositions according to actual use of variables. For 

559 
example: 

560 

561 
assume "A x" and "B y" for x and y 

562 

563 
is equivalent to: 

564 

565 
assume "\<And>x. A x" and "\<And>y. B y" 

566 

60595  567 
* The meaning of 'show' with Pure rule statements has changed: premises 
568 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  569 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
570 
follows: 

60595  571 

572 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

573 

574 
or: 

575 

576 
show "C x" if "A x" "B x" for x 

577 

578 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

579 

580 
show "C x" when "A x" "B x" for x 

581 

60459  582 
* New command 'consider' states rules for generalized elimination and 
583 
case splitting. This is like a toplevel statement "theorem obtains" used 

584 
within a proof body; or like a multibranch 'obtain' without activation 

585 
of the local context elements yet. 

586 

60455  587 
* Proof method "cases" allows to specify the rule as first entry of 
588 
chained facts. This is particularly useful with 'consider': 

589 

590 
consider (a) A  (b) B  (c) C <proof> 

591 
then have something 

592

593

602 

60565  603 
* Command 'case' allows fact name and attribute specification like this: 
604 

605 
case a: (c xs) 

606 
case a [attributes]: (c xs) 

607 

608 
Facts that are introduced by invoking the case context are uniformly 

609 
qualified by "a"; the same name is used for the cumulative fact. The old 

610 
form "case (c xs) [attributes]" is no longer supported. Rare 

611 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

612 
and always put attributes in front.

698 
'abbreviation' is also kept for morphims that only change the involved 
62017  699 
parameters, and only 'notation' is suppressed. This can be of great help 
700 
when working with complex locale hierarchies, because proof states are 

701 
displayed much more succinctly. It also means that only notation needs 

702 
to be redeclared if desired, as illustrated by this example:

* The 'typedef' command has been upgraded from a partially checked 
743 
"axiomatization", to a full definitional specification that takes the 

744 
global collection of overloaded constant / type definitions into 

745 
account. Type definitions with open dependencies on overloaded 

746 
definitions need to be specified as "typedef (overloaded)". This 

747 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

748 

749 
* Qualification of various formal entities in the libraries is done more 

750 
uniformly via "context begin qualified definition ... end" instead of 

751 
oldstyle "hide_const (open) ...". Consequently, both the defined 

752 
constant and its defining fact become qualified, e.g. Option.is_none and 

753 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

754 

755 
* Some old and rarely used ASCII replacement syntax has been removed. 

756 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

757 
The subsequent commands help to reproduce the old forms, e.g. to 

758 
simplify porting old theories:

783 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

784 

785 
* The alternative notation "\<Colon>" for type and sort constraints has been 

786 
removed: in LaTeX document output it looks the same as "::". 

787 
INCOMPATIBILITY, use plain "::" instead. 

788 

789 
* Commands 'inductive' and 'inductive_set' work better when names for 

790 
intro rules are omitted: the "cases" and "induct" rules no longer 

791 
declare empty case_names, but no case_names at all. This allows to use 

792 
numbered cases in proofs, without requiring method "goal_cases". 

793 

794 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

795 
lowlevel facts of the internal construction only if the option 

62093  796 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  797 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
798 

799 
* Recursive function definitions ('fun', 'function', 'partial_function') 

800 
expose lowlevel facts of the internal construction only if the option 

62205  801 
"function_internals" is enabled. Its internal inductive definition is 
802 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  803 

804 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

805 
of the internal construction only if the option "bnf_internals" is 

806 
enabled. This supersedes the former option "bnf_note_all". Rare 

807 
INCOMPATIBILITY. 

62017  808 

809 
* Combinator to represent case distinction on products is named 

810 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

811 
theorem aliasses have been retained.

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

859 
'real' is no longer overloaded, but has type 'nat => real' and 

860 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

861 
abbreviates of_int for that type. Other overloaded instances of 'real' 

862 
have been replaced by 'real_of_ereal' and 'real_of_float'.

1200 
together with an attribute to maintain the content incrementally. This 

1201 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
1263 

1264 
* Document markup commands 'chapter', 'section', 'subsection', 

1265 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1266 
context, even before the initial 'theory' command. Obsolete proof 

1267 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1268 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1269 
instead. The old 'header' command is still retained for some time, but 

1270 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1271 
update_header"). Minor INCOMPATIBILITY. 

1272 

60009  1273 
* Official support for "tt" style variants, via \isatt{...} or 
1274 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1275 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1276 
as argument to other macros (such as footnotes). 

1277 

1278 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1279 
style. 

1280 

1281 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1282 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1283 

59951  1284 
* Diagnostic commands and document markup commands within a proof do not 
1285 
affect the command tag for output. Thus commands like 'thm' are subject 

1286 
to proof document structure, and no longer "stick out" accidentally. 

1287 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1288 
tags. Potential INCOMPATIBILITY in exotic situations. 

1289 

1290 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1291 
which is also accessible via document antiquotation option "margin". 

1292 
Only the margin for document output may be changed, but not the global 

1293 
pretty printing: that is 76 for plain console output, and adapted 

1294 
dynamically in GUI frontends. Implementations of document 

1295 
antiquotations need to observe the margin explicitly according to 

1296 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

INCOMPATIBILITY. 
58192  1357 
 The "no_code" option to "free_constructors", "datatype_new", and 
1358 
"codatatype" has been renamed "plugins del: code". 

1359 
INCOMPATIBILITY. 

58044  1360 
 The rules "set_empty" have been removed. They are easy 
1361 
consequences of other set rules "by auto". 

1362 
INCOMPATIBILITY. 

1363 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1364 
attribute. This can influence the behavior of the "cases" proof 
1365 
method when more than one case rule is applicable (e.g., an 

1366 
assumption is of the form "w : set ws" and the method "cases w" 

1367 
is invoked). The solution is to specify the case rule explicitly 

1368 
(e.g. "cases w rule: widget.exhaust"). 

1369 
INCOMPATIBILITY.

 Renamed theories:

1377 
INCOMPATIBILITY. 

60114  1378 
 Lifting and Transfer setup for basic HOL types sum and prod (also 
1379 
option) is now performed by the BNF package. Theories Lifting_Sum, 

1380 
Lifting_Product and Lifting_Option from Main became obsolete and 

1381 
were removed. Changed definitions of the relators rel_prod and 

1382 
rel_sum (using inductive). 

60111  1383 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  1384 
of rel_prod_def and rel_sum_def. 
1385 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

1386 
changed (e.g. map_prod_transfer ~> prod.map_transfer). 

60261  1387 
 Parametricity theorems for map functions, relators, set functions, 
1388 
constructors, case combinators, discriminators, selectors and 

1389 
(co)recursors are automatically proved and registered as transfer 

1390 
rules.
