*** 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is superseded by "(\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 

45 
method. 

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.

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.

364 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

365 
'SML_file_no_debug' control compilation of sources with or without 

366 
debugging information. The Debugger panel allows to set breakpoints (via 

367

368 
expressions etc. At least one Debugger view needs to be active to have 

369

374

61215  379

* The text overview column (status of errors, warnings etc.) is updated 
381 
asynchronously, leading to much better editor reactivity. Moreover, the 

382 
full document node content is taken into account. The width of the 

383 
column is scaled according to the main text area font, for improved 

384 
visibility. 

385 

386 
* The main text area no longer changes its color hue in outdated 

387 
situations. The text overview column takes over the role to indicate 

388 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

389 
due to adhoc updates by auxiliary GUI components, such as the State 

390 
panel.

510 

60449  511 
The local assumptions are bound to the name "that". The result is 
512 
exported from context of the statement as usual. The above roughly 

60414  513 
corresponds to a raw proof block like this: 
514

524 

61733  525 
* Assumptions ('assume', 'presume') allow structured rule statements 
526 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  527 

528 
assume result: "C x y" 

529 
if "A x" and "B y" 

530 
for x :: 'a and y :: 'a 

531 

532 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

533 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

534 

535 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

536 
only effects propositions according to actual use of variables. For 

537 
example: 

538 

539 
assume "A x" and "B y" for x and y 

540 

541 
is equivalent to: 

542 

543 
assume "\<And>x. A x" and "\<And>y. B y" 

544 

60595  545 
* The meaning of 'show' with Pure rule statements has changed: premises 
546 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  547 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
548 
follows: 

60595  549 

550 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

551 

552 
or: 

553 

554 
show "C x" if "A x" "B x" for x 

555 

556 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

557 

558 
show "C x" when "A x" "B x" for x 

559 

60459  560 
* New command 'consider' states rules for generalized elimination and 
561 
case splitting. This is like a toplevel statement "theorem obtains" used 

562 
within a proof body; or like a multibranch 'obtain' without activation 

563 
of the local context elements yet. 

564 

60455  565 
* Proof method "cases" allows to specify the rule as first entry of 
566 
chained facts. This is particularly useful with 'consider': 

567 

568 
consider (a) A  (b) B  (c) C <proof> 

569 
then have something 

570 
proof cases 

571

572 
then show ?thesis <proof> 

573

574

case c 

578

580 

60565  581 
* Command 'case' allows fact name and attribute specification like this: 
582 

583 
case a: (c xs) 

584 
case a [attributes]: (c xs) 

585 

586 
Facts that are introduced by invoking the case context are uniformly 

587 
qualified by "a"; the same name is used for the cumulative fact. The old 

588 
form "case (c xs) [attributes]" is no longer supported. Rare 

589 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

590 
and always put attributes in front.

600 
relevant for 'using', 'including', 'supply':

704

705 

60331  706 
* Configuration option rule_insts_schematic has been discontinued 
62017  707 
(intermediate legacy feature in Isabelle2015). INCOMPATIBILITY.

62017  720 
* The 'typedef' command has been upgraded from a partially checked 
721 
"axiomatization", to a full definitional specification that takes the 

722 
global collection of overloaded constant / type definitions into 

723 
account. Type definitions with open dependencies on overloaded 

724 
definitions need to be specified as "typedef (overloaded)". This 

725 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

726 

727 
* Qualification of various formal entities in the libraries is done more 

728 
uniformly via "context begin qualified definition ... end" instead of 

729 
oldstyle "hide_const (open) ...". Consequently, both the defined 

730 
constant and its defining fact become qualified, e.g. Option.is_none and 

731 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

732 

733 
* Some old and rarely used ASCII replacement syntax has been removed. 

734 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

735 
The subsequent commands help to reproduce the old forms, e.g. to 

736 
simplify porting old theories: 

737 

738 
notation iff (infixr "<>" 25) 

739 

740 
notation Times (infixr "<*>" 80) 

741 

742 
type_notation Map.map (infixr "~=>" 0) 

743

744

746 

747

748 
notation FuncSet.extensional_funcset (infixr ">\<^sub>E" 60) 

749 

750 
notation Omega_Words_Fun.conc (infixr "conc" 65) 

751 

752 
notation Preorder.equiv ("op ~~") 

753 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

754 

755 
notation (in topological_space) tendsto (infixr ">" 55) 

756 
notation (in topological_space) LIMSEQ ("((_)/ > (_))" [60, 60] 60) 

757 
notation LIM ("((_)/  (_)/ > (_))" [60, 0, 60] 60) 

758 

759 
notation NSA.approx (infixl "@=" 50) 

760 
notation NSLIMSEQ ("((_)/ NS> (_))" [60, 60] 60) 

761 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

762 

763 
* The alternative notation "\<Colon>" for type and sort constraints has been 

764 
removed: in LaTeX document output it looks the same as "::". 

765 
INCOMPATIBILITY, use plain "::" instead. 

766 

767 
* Commands 'inductive' and 'inductive_set' work better when names for 

768 
intro rules are omitted: the "cases" and "induct" rules no longer 

769 
declare empty case_names, but no case_names at all. This allows to use 

770 
numbered cases in proofs, without requiring method "goal_cases". 

771 

772 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

773 
lowlevel facts of the internal construction only if the option 

62093  774 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  775 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
776 

777 
* Recursive function definitions ('fun', 'function', 'partial_function') 

778 
expose lowlevel facts of the internal construction only if the option 

62205  779 
"function_internals" is enabled. Its internal inductive definition is 
780 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  781 

782 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

783 
of the internal construction only if the option "bnf_internals" is 

784 
enabled. This supersedes the former option "bnf_note_all". Rare 

785 
INCOMPATIBILITY. 

62017  786 

787 
* Combinator to represent case distinction on products is named 

788 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

789 
theorem aliasses have been retained.

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

837 
'real' is no longer overloaded, but has type 'nat => real' and 

838 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

839 
abbreviates of_int for that type. Other overloaded instances of 'real' 

840 
have been replaced by 'real_of_ereal' and 'real_of_float'.

1172 

59951  1173

1176 

1177 
* Command 'named_theorems' declares a dynamic fact within the context, 

1178 
together with an attribute to maintain the content incrementally. This 

1179 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
1241 

1242 
* Document markup commands 'chapter', 'section', 'subsection', 

1243 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1244 
context, even before the initial 'theory' command. Obsolete proof 

1245 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1246 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1247 
instead. The old 'header' command is still retained for some time, but 

1248 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1249 
update_header"). Minor INCOMPATIBILITY. 

1250 

60009  1251 
* Official support for "tt" style variants, via \isatt{...} or 
1252 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1253 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1254 
as argument to other macros (such as footnotes). 

1255 

1256 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1257 
style. 

1258 

1259 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1260 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1261 

59951  1262 
* Diagnostic commands and document markup commands within a proof do not 
1263 
affect the command tag for output. Thus commands like 'thm' are subject 

1264 
to proof document structure, and no longer "stick out" accidentally. 

1265 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1266 
tags. Potential INCOMPATIBILITY in exotic situations. 

1267 

1268 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1269 
which is also accessible via document antiquotation option "margin". 

1270 
Only the margin for document output may be changed, but not the global 

1271 
pretty printing: that is 76 for plain console output, and adapted 

1272 
dynamically in GUI frontends. Implementations of document 

1273 
antiquotations need to observe the margin explicitly according to 

1274 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

INCOMPATIBILITY. 
58192  1335 
 The "no_code" option to "free_constructors", "datatype_new", and 
1336 
"codatatype" has been renamed "plugins del: code". 

1337 
INCOMPATIBILITY. 

58044  1338 
 The rules "set_empty" have been removed. They are easy 
1339 
consequences of other set rules "by auto". 

1340 
INCOMPATIBILITY. 

1341 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1342 
attribute. This can influence the behavior of the "cases" proof 
1343 
method when more than one case rule is applicable (e.g., an 

1344 
assumption is of the form "w : set ws" and the method "cases w" 

1345 
is invoked). The solution is to specify the case rule explicitly 

1346 
(e.g. "cases w rule: widget.exhaust"). 

1347

INCOMPATIBILITY. 

60114  1356 
 Lifting and Transfer setup for basic HOL types sum and prod (also 
1357 
option) is now performed by the BNF package. Theories Lifting_Sum, 

1358 
Lifting_Product and Lifting_Option from Main became obsolete and 

1359 
were removed. Changed definitions of the relators rel_prod and 

1360 
rel_sum (using inductive). 

60111  1361 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  1362 
of rel_prod_def and rel_sum_def. 
1363 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

1364 
changed (e.g. map_prod_transfer ~> prod.map_transfer). 

60261  1365 
 Parametricity theorems for map functions, relators, set functions, 
1366 
constructors, case combinators, discriminators, selectors and 

1367 
(co)recursors are automatically proved and registered as transfer 

1368 
rules.
