*** General *** 
11 

12 
* New symbol \<circle>, e.g. for temporal operator. 

13 

62453  14 
* Old 'header' command is no longer supported (legacy since 
15 
Isabelle2015).

typesetting. E.g. to produce proof holes in examples and documentation. 
62216  22 

23 

62327  24 
*** HOL *** 
25 

62522  26 
* New abbreviations for negated existence (but not bounded existence): 
27 

28 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

29 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

30 

62521  31 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
32 
has been removed for output. It is retained for input only, until it is 

33 
eliminated altogether. 

34 

62327  35 
* (Co)datatype package: 
62693  36 
 New commands for defining corecursive functions and reasoning about 
37 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive', 

38 
'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof 

39 
method. 

40 
 The predicator :: ('a => bool) => 'a F => bool is now a firstclass 

62332  41 
citizen in bounded natural functors 
62693  42 
 'primrec' now allows nested calls through the predicator in addition 
62327  43 
to the map function. 
62693  44 
 'bnf' automatically discharges reflexive proof obligations 
45 
 'bnf' outputs a slightly modified proof obligation expressing rel in 

62332  46 
terms of map and set 
47 
(not giving a specification for rel makes this one reflexive) 

62693  48 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
62332  49 
(not giving a specification for pred makes this one reflexive) 
62693  50 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment 
62335  51 
 Renamed lemmas: 
52 
rel_prod_apply ~> rel_prod_inject 

53 
pred_prod_apply ~> pred_prod_inject

55 
 The "size" plugin has been made compatible again with locales. 
62327  56 

62407  57 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
58 
resemble the f.split naming convention, INCOMPATIBILITY. 

62396  59 

62597  60 
* Characters (type char) are modelled as finite algebraic type 
61 
corresponding to {0..255}. 

62 

63 
 Logical representation: 

64 
* 0 is instantiated to the ASCII zero character.

62678  73 
* All other canonical characters are printed as "CHR 0xXX" 
74 
with XX being the hexadecimal character code. "CHR n" 

62597  75 
is parsable for every numeral expression n. 
62598  76 
* Noncanonical characters have no special syntax and are 
62597  77 
printed as their logical representation. 
78 
 Explicit conversions from and to the natural numbers are 

79 
provided as char_of_nat, nat_of_char (as before). 

80 
 The auxiliary nibble type has been discontinued.

334

335

Commandline tool "isabelle update_theorems" updates theory sources

358 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

359 
'SML_file_no_debug' control compilation of sources with or without 

360 
debugging information. The Debugger panel allows to set breakpoints (via 

361 
context menu), step through stopped threads, evaluate local ML 

362 
expressions etc. At least one Debugger view needs to be active to have 

363 
any effect on the running ML program. 

60984  364

* The State panel manages explicit proof state output, with dynamic 
366 
autoupdate according to cursor movement. Alternatively, the jEdit 

367 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

368 
update. 

61729  369 

370 
* The Output panel no longer shows proof state output by default, to 

371 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

372 
enable option "editor_output_state". 

61215  373 

61803  374 
* The text overview column (status of errors, warnings etc.) is updated 
375 
asynchronously, leading to much better editor reactivity. Moreover, the 

376 
full document node content is taken into account. The width of the 

377 
column is scaled according to the main text area font, for improved 

378 
visibility. 

379 

380 
* The main text area no longer changes its color hue in outdated 

381 
situations. The text overview column takes over the role to indicate 

382 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

383 
due to adhoc updates by auxiliary GUI components, such as the State 

384 
panel.

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

503

504 

60449  505 
The local assumptions are bound to the name "that". The result is 
506 
exported from context of the statement as usual. The above roughly 

60414  507 
corresponds to a raw proof block like this: 
508 

509

518 

61733  519 
* Assumptions ('assume', 'presume') allow structured rule statements 
520 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  521 

522 
assume result: "C x y" 

523 
if "A x" and "B y" 

524 
for x :: 'a and y :: 'a 

525 

526 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

527 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

528 

529 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

530 
only effects propositions according to actual use of variables. For 

531 
example: 

532 

533 
assume "A x" and "B y" for x and y 

534 

535 
is equivalent to: 

536 

537 
assume "\<And>x. A x" and "\<And>y. B y" 

538 

60595  539 
* The meaning of 'show' with Pure rule statements has changed: premises 
540 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  541 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
542 
follows: 

60595  543 

544 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

545 

546 
or: 

547 

548 
show "C x" if "A x" "B x" for x 

549 

550 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

551 

552 
show "C x" when "A x" "B x" for x 

553 

60459  554 
* New command 'consider' states rules for generalized elimination and 
555 
case splitting. This is like a toplevel statement "theorem obtains" used 

556 
within a proof body; or like a multibranch 'obtain' without activation 

557 
of the local context elements yet. 

558 

60455  559 
* Proof method "cases" allows to specify the rule as first entry of 
560 
chained facts. This is particularly useful with 'consider': 

561 

562 
consider (a) A  (b) B  (c) C <proof> 

563 
then have something 

564 
proof cases 

565 
case a 

566 
then show ?thesis <proof> 

567

568 
case b 

569 
then show ?thesis <proof> 

570

571 
case c 

572 
then show ?thesis <proof> 

573 
qed 

574 

60565  575 
* Command 'case' allows fact name and attribute specification like this: 
576 

577 
case a: (c xs) 

578 
case a [attributes]: (c xs) 

579 

580 
Facts that are introduced by invoking the case context are uniformly 

581 
qualified by "a"; the same name is used for the cumulative fact. The old 

582 
form "case (c xs) [attributes]" is no longer supported. Rare 

583 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

584 
and always put attributes in front.

statements: result is abstracted over unknowns.

* Command 'print_definitions' prints dependencies of definitional 
698

699 

60331  700 
* Configuration option rule_insts_schematic has been discontinued 
62017  701 
(intermediate legacy feature in Isabelle2015). INCOMPATIBILITY. 
60331  702

* Abbreviations in type classes now carry proper sort constraint. Rare 
704 
INCOMPATIBILITY in situations where the previous misbehaviour has been 

705 
exploited.

707 
* Refinement of userspace type system in type classes: pseudolocal 

62205  708 
operations behave more similar to abbreviations. Potential 
60347  709 
INCOMPATIBILITY in exotic situations.

62017  714 
* The 'typedef' command has been upgraded from a partially checked 
715 
"axiomatization", to a full definitional specification that takes the 

716 
global collection of overloaded constant / type definitions into 

717 
account. Type definitions with open dependencies on overloaded 

718 
definitions need to be specified as "typedef (overloaded)". This 

719 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

720 

721 
* Qualification of various formal entities in the libraries is done more 

722 
uniformly via "context begin qualified definition ... end" instead of 

723 
oldstyle "hide_const (open) ...". Consequently, both the defined 

724 
constant and its defining fact become qualified, e.g. Option.is_none and 

725 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

726 

727 
* Some old and rarely used ASCII replacement syntax has been removed. 

728 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

729 
The subsequent commands help to reproduce the old forms, e.g. to 

730 
simplify porting old theories: 

731 

732 
notation iff (infixr "<>" 25) 

733 

734 
notation Times (infixr "<*>" 80) 

735 

736 
type_notation Map.map (infixr "~=>" 0) 

737 
notation Map.map_comp (infixl "o'_m" 55) 

738 

739 
type_notation FinFun.finfun ("(_ =>f /_)" [22, 21] 21) 

740 

741 
notation FuncSet.funcset (infixr ">" 60) 

742 
notation FuncSet.extensional_funcset (infixr ">\<^sub>E" 60) 

743 

744 
notation Omega_Words_Fun.conc (infixr "conc" 65) 

745 

746 
notation Preorder.equiv ("op ~~") 

747 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

748 

749 
notation (in topological_space) tendsto (infixr ">" 55) 

750 
notation (in topological_space) LIMSEQ ("((_)/ > (_))" [60, 60] 60) 

751 
notation LIM ("((_)/  (_)/ > (_))" [60, 0, 60] 60) 

752 

753 
notation NSA.approx (infixl "@=" 50) 

754 
notation NSLIMSEQ ("((_)/ NS> (_))" [60, 60] 60) 

755 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

756 

757 
* The alternative notation "\<Colon>" for type and sort constraints has been 

758 
removed: in LaTeX document output it looks the same as "::". 

759 
INCOMPATIBILITY, use plain "::" instead. 

760 

761 
* Commands 'inductive' and 'inductive_set' work better when names for 

762 
intro rules are omitted: the "cases" and "induct" rules no longer 

763 
declare empty case_names, but no case_names at all. This allows to use 

764 
numbered cases in proofs, without requiring method "goal_cases". 

765 

766 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

767 
lowlevel facts of the internal construction only if the option 

62093  768 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  769 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
770 

771 
* Recursive function definitions ('fun', 'function', 'partial_function') 

772 
expose lowlevel facts of the internal construction only if the option 

62205  773 
"function_internals" is enabled. Its internal inductive definition is 
774 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  775 

776 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

777 
of the internal construction only if the option "bnf_internals" is 

778 
enabled. This supersedes the former option "bnf_note_all". Rare 

779 
INCOMPATIBILITY. 

62017  780 

781 
* Combinator to represent case distinction on products is named 

782 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

783 
theorem aliasses have been retained.

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

831 
'real' is no longer overloaded, but has type 'nat => real' and 

832 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

833 
abbreviates of_int for that type. Other overloaded instances of 'real' 

834 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* Command 'experiment' opens an anonymous locale context with private 
1165

1166 

59951  1167 
* Command 'notepad' requires proper nesting of begin/end and its proof

structure in the body: 'oops' is no longer supported here. Minor 

1169 
INCOMPATIBILITY, use 'sorry' instead. 

1170 

1171 
* Command 'named_theorems' declares a dynamic fact within the context, 

1172 
together with an attribute to maintain the content incrementally. This 

1173 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1174

*** Document preparation *** 
1235 

1236 
* Document markup commands 'chapter', 'section', 'subsection', 

1237 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1238 
context, even before the initial 'theory' command. Obsolete proof 

1239 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1240 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1241 
instead. The old 'header' command is still retained for some time, but 

1242 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1243 
update_header"). Minor INCOMPATIBILITY. 

1244 

60009  1245 
* Official support for "tt" style variants, via \isatt{...} or 
1246 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1247 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1248 
as argument to other macros (such as footnotes). 

1249 

1250 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1251 
style. 

1252 

1253 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1254 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1255 

59951  1256 
* Diagnostic commands and document markup commands within a proof do not 
1257 
affect the command tag for output. Thus commands like 'thm' are subject 

1258 
to proof document structure, and no longer "stick out" accidentally. 

1259 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1260 
tags. Potential INCOMPATIBILITY in exotic situations. 

1261 

1262 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1263 
which is also accessible via document antiquotation option "margin". 

1264 
Only the margin for document output may be changed, but not the global 

1265 
pretty printing: that is 76 for plain console output, and adapted 

1266 
dynamically in GUI frontends. Implementations of document 

1267 
antiquotations need to observe the margin explicitly according to 

1268 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

 The "no_code" option to "free_constructors", "datatype_new", and 
1330 
"codatatype" has been renamed "plugins del: code". 

1331 
INCOMPATIBILITY. 

58044  1332 
 The rules "set_empty" have been removed. They are easy 
1333 
consequences of other set rules "by auto". 

1334 
INCOMPATIBILITY. 

1335 
 The rule "set_cases" is now registered with the "[cases set]" 

57990  1336 
attribute. This can influence the behavior of the "cases" proof 
1337 
method when more than one case rule is applicable (e.g., an 

1338 
assumption is of the form "w : set ws" and the method "cases w" 

1339 
is invoked). The solution is to specify the case rule explicitly 

1340 
(e.g. "cases w rule: widget.exhaust").

 Lifting and Transfer setup for basic HOL types sum and prod (also 
1351 
option) is now performed by the BNF package. Theories Lifting_Sum, 

1352 
Lifting_Product and Lifting_Option from Main became obsolete and 

1353 
were removed. Changed definitions of the relators rel_prod and 

1354 
rel_sum (using inductive). 

60111  1355 
INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead 
60114  1356 
of rel_prod_def and rel_sum_def. 
1357 
Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names 

1358 
changed (e.g. map_prod_transfer ~> prod.map_transfer). 

60261  1359 
 Parametricity theorems for map functions, relators, set functions, 
1360 
constructors, case combinators, discriminators, selectors and 

1361 
(co)recursors are automatically proved and registered as transfer 

1362 
rules.

'rep_datatype' has been renamed 'old_rep_datatype'. They are 
1367 
provided by "~~/src/HOL/Library/Old_Datatype.thy". See

 CVC4 is now included with Isabelle instead of CVC3 and run by 
1383 
default. 

59965  1384 
 Z3 is now always enabled by default, now that it is fully open 
1385 
source. The "z3_non_commercial" option is discontinued. 

57737  1386

58067  1394 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1395 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1396 
until applications have been ported to use the new 'smt' method. For 

1397 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1398 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1399 
point to it.
