*** 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is superseded by "(\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).

typesetting. E.g. to produce proof holes in examples and documentation. 
62216  28 

29 

62327  30 
*** HOL *** 
31 

62522  32 
* New abbreviations for negated existence (but not bounded existence): 
33 

34 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

35 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

36 

62521  37 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
38 
has been removed for output. It is retained for input only, until it is 

39 
eliminated altogether. 

40 

62327  41 
* (Co)datatype package: 
62693  42 
 New commands for defining corecursive functions and reasoning about 
43 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive', 

44 
'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof 

62842  45 
method. See 'isabelle doc corec'. 
62693  46 
 The predicator :: ('a => bool) => 'a F => bool is now a firstclass 
62332  47 
citizen in bounded natural functors 
62693  48 
 'primrec' now allows nested calls through the predicator in addition 
62327  49 
to the map function. 
62693  50 
 'bnf' automatically discharges reflexive proof obligations 
51 
 'bnf' outputs a slightly modified proof obligation expressing rel in 

62332  52 
terms of map and set 
53 
(not giving a specification for rel makes this one reflexive) 

62693  54 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
62332  55 
(not giving a specification for pred makes this one reflexive) 
62693  56 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment 
62335  57 
 Renamed lemmas: 
58 
rel_prod_apply ~> rel_prod_inject 

59 
pred_prod_apply ~> pred_prod_inject

61 
 The "size" plugin has been made compatible again with locales. 
62327  62 

62407  63 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
64 
resemble the f.split naming convention, INCOMPATIBILITY. 

62396  65 

62597  66 
* Characters (type char) are modelled as finite algebraic type 
67 
corresponding to {0..255}. 

68 

69 
 Logical representation: 

70 
* 0 is instantiated to the ASCII zero character.

* The ASCII zero character is printed and parsed as "0". 
62678  79 
* All other canonical characters are printed as "CHR 0xXX" 
80 
with XX being the hexadecimal character code. "CHR n" 

62597  81 
is parsable for every numeral expression n. 
62598  82 
* Noncanonical characters have no special syntax and are 
62597  83 
printed as their logical representation. 
84 
 Explicit conversions from and to the natural numbers are 

85 
provided as char_of_nat, nat_of_char (as before). 

86 
 The auxiliary nibble type has been discontinued.

This is particularly useful for conditional compilation, without

* The text overview column (status of errors, warnings etc.) is updated 
395 
asynchronously, leading to much better editor reactivity. Moreover, the 

396 
full document node content is taken into account. The width of the 

397 
column is scaled according to the main text area font, for improved 

398

399 

400 
* The main text area no longer changes its color hue in outdated 

401 
situations. The text overview column takes over the role to indicate 

402 
unfinished edits in the PIDE pipeline. This avoids flashing text display

404

524 

60449  525 
The local assumptions are bound to the name "that". The result is 
526 
exported from context of the statement as usual. The above roughly 

60414  527 
corresponds to a raw proof block like this: 
528

538 

61733  539 
* Assumptions ('assume', 'presume') allow structured rule statements 
540 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  541 

542 
assume result: "C x y" 

543 
if "A x" and "B y" 

544 
for x :: 'a and y :: 'a 

545 

546 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

547 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

548 

549 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

550 
only effects propositions according to actual use of variables. For 

551 
example: 

552 

553 
assume "A x" and "B y" for x and y 

554 

555 
is equivalent to: 

556 

557 
assume "\<And>x. A x" and "\<And>y. B y" 

558 

60595  559 
* The meaning of 'show' with Pure rule statements has changed: premises 
560 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  561 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
562 
follows: 

60595  563 

564 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

565 

566 
or: 

567 

568 
show "C x" if "A x" "B x" for x 

569 

570 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

571 

572 
show "C x" when "A x" "B x" for x 

573 

60459  574 
* New command 'consider' states rules for generalized elimination and 
575 
case splitting. This is like a toplevel statement "theorem obtains" used 

576 
within a proof body; or like a multibranch 'obtain' without activation 

577 
of the local context elements yet. 

578 

60455  579 
* Proof method "cases" allows to specify the rule as first entry of 
580 
chained facts. This is particularly useful with 'consider': 

581 

582 
consider (a) A  (b) B  (c) C <proof> 

583 
then have something 

584

585

594 

60565  595 
* Command 'case' allows fact name and attribute specification like this: 
596 

597 
case a: (c xs) 

598 
case a [attributes]: (c xs) 

599 

600 
Facts that are introduced by invoking the case context are uniformly 

601 
qualified by "a"; the same name is used for the cumulative fact. The old 

602 
form "case (c xs) [attributes]" is no longer supported. Rare 

603 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

604 
and always put attributes in front.

printing terms. Previously 'abbreviation' and 'notation' declarations 
689 
would be suppressed for morphisms except term identity. Now

690 
'abbreviation' is also kept for morphims that only change the involved 
62017  691 
parameters, and only 'notation' is suppressed. This can be of great help 
692 
when working with complex locale hierarchies, because proof states are 

693 
displayed much more succinctly. It also means that only notation needs 

694 
to be redeclared if desired, as illustrated by this example:

* The 'typedef' command has been upgraded from a partially checked 
735 
"axiomatization", to a full definitional specification that takes the 

736 
global collection of overloaded constant / type definitions into 

737 
account. Type definitions with open dependencies on overloaded 

738 
definitions need to be specified as "typedef (overloaded)". This 

739 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

740 

741 
* Qualification of various formal entities in the libraries is done more 

742 
uniformly via "context begin qualified definition ... end" instead of 

743 
oldstyle "hide_const (open) ...". Consequently, both the defined 

744 
constant and its defining fact become qualified, e.g. Option.is_none and 

745 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

746 

747 
* Some old and rarely used ASCII replacement syntax has been removed. 

748 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

749 
The subsequent commands help to reproduce the old forms, e.g. to 

750 
simplify porting old theories: 

751 

752 
notation iff (infixr "<>" 25) 

753 

754

755

765 

766

767

775 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

776 

777 
* The alternative notation "\<Colon>" for type and sort constraints has been 

778 
removed: in LaTeX document output it looks the same as "::". 

779 
INCOMPATIBILITY, use plain "::" instead. 

780 

781 
* Commands 'inductive' and 'inductive_set' work better when names for 

782 
intro rules are omitted: the "cases" and "induct" rules no longer 

783 
declare empty case_names, but no case_names at all. This allows to use 

784 
numbered cases in proofs, without requiring method "goal_cases". 

785 

786 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

787 
lowlevel facts of the internal construction only if the option 

62093  788 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  789 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
790 

791 
* Recursive function definitions ('fun', 'function', 'partial_function') 

792 
expose lowlevel facts of the internal construction only if the option 

62205  793 
"function_internals" is enabled. Its internal inductive definition is 
794 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  795 

796 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

797 
of the internal construction only if the option "bnf_internals" is 

798 
enabled. This supersedes the former option "bnf_note_all". Rare 

799 
INCOMPATIBILITY. 

62017  800 

801 
* Combinator to represent case distinction on products is named 

802 
"case_prod", uniformly, discontinuing any input aliasses. Very popular

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

851 
'real' is no longer overloaded, but has type 'nat => real' and 

852 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

853 
abbreviates of_int for that type. Other overloaded instances of 'real' 

854 
have been replaced by 'real_of_ereal' and 'real_of_float'.

1186 

59951  1187 
* Command 'notepad' requires proper nesting of begin/end and its proof

INCOMPATIBILITY, use 'sorry' instead. 

1190 

1191 
* Command 'named_theorems' declares a dynamic fact within the context, 

1192 
together with an attribute to maintain the content incrementally. This 

1193 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1194 
of semantics due to external visual order vs. internal reverse order.

* Improved folding mode "isabelle" based on Isar syntax. Alternatively, 
1228 
the "sidekick" mode may be used for document structure.

*** Document preparation *** 
1255 

1256 
* Document markup commands 'chapter', 'section', 'subsection', 

1257 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1258 
context, even before the initial 'theory' command. Obsolete proof 

1259 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1260 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1261 
instead. The old 'header' command is still retained for some time, but 

1262 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1263 
update_header"). Minor INCOMPATIBILITY. 

1264 

60009  1265 
* Official support for "tt" style variants, via \isatt{...} or 
1266 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1267 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1268 
as argument to other macros (such as footnotes). 

1269 

1270 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1271 
style. 

1272 

1273 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1274 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1275 

59951  1276 
* Diagnostic commands and document markup commands within a proof do not 
1277 
affect the command tag for output. Thus commands like 'thm' are subject 

1278 
to proof document structure, and no longer "stick out" accidentally. 

1279 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1280 
tags. Potential INCOMPATIBILITY in exotic situations. 

1281 

1282 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1283 
which is also accessible via document antiquotation option "margin". 

1284 
Only the margin for document output may be changed, but not the global 

1285 
pretty printing: that is 76 for plain console output, and adapted 

1286 
dynamically in GUI frontends. Implementations of document 

1287 
antiquotations need to observe the margin explicitly according to 

1288 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1348 
INCOMPATIBILITY. 
58192  1349 
 The "no_code" option to "free_constructors", "datatype_new", and 
1350 
"codatatype" has been renamed "plugins del: code". 

1351 
INCOMPATIBILITY. 

58044  1352 
 The rules "set_empty" have been removed. They are easy 
1353 
consequences of other set rules "by auto". 

1354 
INCOMPATIBILITY. 

1355 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1356 
attribute. This can influence the behavior of the "cases" proof 
1357 
method when more than one case rule is applicable (e.g., an 

1358 
assumption is of the form "w : set ws" and the method "cases w" 

1359 
is invoked). The solution is to specify the case rule explicitly 

1360 
(e.g. "cases w rule: widget.exhaust"). 

1361 
INCOMPATIBILITY. 

59675  1362 
 Renamed theories: 
1363 
BNF_Comp ~> BNF_Composition 

1364 
BNF_FP_Base ~> BNF_Fixpoint_Base 

1365 
BNF_GFP ~> BNF_Greatest_Fixpoint 

1366 
BNF_LFP ~> BNF_Least_Fixpoint 

1367 
BNF_Constructions_on_Wellorders ~> BNF_Wellorder_Constructions 

1368 
Cardinals/Constructions_on_Wellorders ~> Cardinals/Wellorder_Constructions 

1369 
INCOMPATIBILITY. 

60114  1370 
 Lifting and Transfer setup for basic HOL types sum and prod (also 
1371 
option) is now performed by the BNF package. Theories Lifting_Sum, 

1372 
Lifting_Product and Lifting_Option from Main became obsolete and 

1373 
were removed. Changed definitions of the relators rel_prod and 

1374 
rel_sum (using inductive). 

60111  1375 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  1376 
of rel_prod_def and rel_sum_def. 
1377 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

1378 
changed (e.g. map_prod_transfer ~> prod.map_transfer). 

60261  1379 
 Parametricity theorems for map functions, relators, set functions, 
1380 
constructors, case combinators, discriminators, selectors and 

1381 
(co)recursors are automatically proved and registered as transfer 

1382 
rules.
