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: 
62332  36 
 the predicator :: ('a => bool) => 'a F => bool is now a firstclass 
37 
citizen in bounded natural functors 

62327  38 
 "primrec" now allows nested calls through the predicator in addition 
39 
to the map function. 

62332  40 
 "bnf" automatically discharges reflexive proof obligations 
41 
"bnf" outputs a slightly modified proof obligation expressing rel in 

42 
terms of map and set 

43 
(not giving a specification for rel makes this one reflexive) 

44 
"bnf" outputs a new proof obligation expressing pred in terms of set 

45 
(not giving a specification for pred makes this one reflexive) 

46 
INCOMPATIBILITY: manual "bnf" declarations may need adjustment 

62335  47 
 Renamed lemmas: 
48 
rel_prod_apply ~> rel_prod_inject 

49 
pred_prod_apply ~> pred_prod_inject

51 
 The "size" plugin has been made compatible again with locales. 
62327  52 

62407  53 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
54 
resemble the f.split naming convention, INCOMPATIBILITY. 

62396  55 

62597  56 
* Characters (type char) are modelled as finite algebraic type 
57 
corresponding to {0..255}. 

58 

59 
 Logical representation: 

60 
* 0 is instantiated to the ASCII zero character. 

61 
* All other characters are represented as »Char n« 

62 
with n being a raw numeral expression less than 256. 

63 
* Expressions of the form »Char n« with n greater than 255 

64 
are noncanonical. 

65 
 Printing and parsing: 

66 
* Printable characters are printed and parsed as »CHR ''…''« 

67 
(as before). 

68 
* The ASCII zero character is printed and parsed as »0«. 

69 
* All other canonical characters are printed as »CHAR 0xXX« 

70 
with XX being the hexadecimal character code. »CHAR n« 

71 
is parsable for every numeral expression n. 

72 
* Noncanonial characters have no special syntax and are 

73 
printed as their logical representation. 

74 
 Explicit conversions from and to the natural numbers are 

75 
provided as char_of_nat, nat_of_char (as before). 

76 
 The auxiliary nibble type has been discontinued. 

77 

78

* Option ML_exception_debugger controls detailed exception trace via the 

220 
Poly/ML debugger. Relevant ML modules need to be compiled beforehand 

221 
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note 

222

scope of 'private' or 'qualified' names. Note that Local_Theory.reset is 

228 
only appropriate when targets are managed, e.g. starting from a global 

229 
theory and returning to it. Regular definitional packages should use 

230

344 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

345 
'SML_file_no_debug' control compilation of sources with or without 

346 
debugging information. The Debugger panel allows to set breakpoints (via 

347 
context menu), step through stopped threads, evaluate local ML 

348 
expressions etc. At least one Debugger view needs to be active to have 

349 
any effect on the running ML program.

* The State panel manages explicit proof state output, with dynamic

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

354

61215  359

* The text overview column (status of errors, warnings etc.) is updated 
361 
asynchronously, leading to much better editor reactivity. Moreover, the 

362 
full document node content is taken into account. The width of the 

363 
column is scaled according to the main text area font, for improved 

364 
visibility. 

365 

366 
* The main text area no longer changes its color hue in outdated 

367 
situations. The text overview column takes over the role to indicate 

368 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

369 
due to adhoc updates by auxiliary GUI components, such as the State 

370 
panel.

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

60414  493 
corresponds to a raw proof block like this:

* Assumptions ('assume', 'presume') allow structured rule statements 
506 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  507 

508 
assume result: "C x y" 

509 
if "A x" and "B y" 

510 
for x :: 'a and y :: 'a 

511 

512 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

513 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

514 

515 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

516 
only effects propositions according to actual use of variables. For 

517 
example: 

518 

519 
assume "A x" and "B y" for x and y 

520 

521 
is equivalent to: 

522 

523 
assume "\<And>x. A x" and "\<And>y. B y" 

524 

60595  525 
* The meaning of 'show' with Pure rule statements has changed: premises 
526 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  527 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
528 
follows: 

60595  529 

530 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

531 

532 
or: 

533 

534 
show "C x" if "A x" "B x" for x 

535 

536 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

537 

538 
show "C x" when "A x" "B x" for x 

539 

60459  540 
* New command 'consider' states rules for generalized elimination and 
541 
case splitting. This is like a toplevel statement "theorem obtains" used 

542 
within a proof body; or like a multibranch 'obtain' without activation 

543 
of the local context elements yet. 

544 

60455  545 
* Proof method "cases" allows to specify the rule as first entry of 
546 
chained facts. This is particularly useful with 'consider': 

547 

548 
consider (a) A  (b) B  (c) C <proof> 

549 
then have something 

550 
proof cases 

551

552

553

560 

60565  561 
* Command 'case' allows fact name and attribute specification like this: 
562 

563 
case a: (c xs) 

564 
case a [attributes]: (c xs) 

565 

566 
Facts that are introduced by invoking the case context are uniformly 

567 
qualified by "a"; the same name is used for the cumulative fact. The old 

568 
form "case (c xs) [attributes]" is no longer supported. Rare 

569 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

570 
and always put attributes in front.

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

711 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

712 

713 
* Some old and rarely used ASCII replacement syntax has been removed. 

714 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

715 
The subsequent commands help to reproduce the old forms, e.g. to 

716 
simplify porting old theories: 

717 

718 
notation iff (infixr "<>" 25) 

719 

720 
notation Times (infixr "<*>" 80) 

721 

722 
type_notation Map.map (infixr "~=>" 0) 

723 
notation Map.map_comp (infixl "o'_m" 55) 

724 

725 
type_notation FinFun.finfun ("(_ =>f /_)" [22, 21] 21) 

726 

727 
notation FuncSet.funcset (infixr ">" 60) 

728 
notation FuncSet.extensional_funcset (infixr ">\<^sub>E" 60) 

729 

730 
notation Omega_Words_Fun.conc (infixr "conc" 65) 

731 

732 
notation Preorder.equiv ("op ~~") 

733 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

734 

735 
notation (in topological_space) tendsto (infixr ">" 55) 

736 
notation (in topological_space) LIMSEQ ("((_)/ > (_))" [60, 60] 60) 

737 
notation LIM ("((_)/  (_)/ > (_))" [60, 0, 60] 60) 

738 

739 
notation NSA.approx (infixl "@=" 50) 

740 
notation NSLIMSEQ ("((_)/ NS> (_))" [60, 60] 60) 

741 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

742 

743 
* The alternative notation "\<Colon>" for type and sort constraints has been 

744 
removed: in LaTeX document output it looks the same as "::". 

745 
INCOMPATIBILITY, use plain "::" instead. 

746 

747 
* Commands 'inductive' and 'inductive_set' work better when names for 

748 
intro rules are omitted: the "cases" and "induct" rules no longer 

749 
declare empty case_names, but no case_names at all. This allows to use 

750 
numbered cases in proofs, without requiring method "goal_cases". 

751 

752 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

753 
lowlevel facts of the internal construction only if the option 

62093  754 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  755 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
756 

757 
* Recursive function definitions ('fun', 'function', 'partial_function') 

758 
expose lowlevel facts of the internal construction only if the option 

62205  759 
"function_internals" is enabled. Its internal inductive definition is 
760 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  761 

762 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

763 
of the internal construction only if the option "bnf_internals" is 

764 
enabled. This supersedes the former option "bnf_note_all". Rare 

765 
INCOMPATIBILITY. 

62017  766 

767 
* Combinator to represent case distinction on products is named 

768 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

769 
theorem aliasses have been retained.

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

817 
'real' is no longer overloaded, but has type 'nat => real' and 

818 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

819 
abbreviates of_int for that type. Other overloaded instances of 'real' 

820 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* Class algebraic_semidom introduces common algebraic notions of 
62017  897 
integral (semi)domains, particularly units. Although logically subsumed 
898 
by fields, is is not a super class of these in order not to burden 

899

* Abstract specification of gcd/lcm operations in classes semiring_gcd,

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

1152 

59951  1153 
* Command 'notepad' requires proper nesting of begin/end and its proof

1156 

1157 
* Command 'named_theorems' declares a dynamic fact within the context, 

1158 
together with an attribute to maintain the content incrementally. This 

1159 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

* Improved folding mode "isabelle" based on Isar syntax. Alternatively, 
1194

*** Document preparation *** 
1221 

1222 
* Document markup commands 'chapter', 'section', 'subsection', 

1223 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1224 
context, even before the initial 'theory' command. Obsolete proof 

1225 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1226 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1227 
instead. The old 'header' command is still retained for some time, but 

1228 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1229 
update_header"). Minor INCOMPATIBILITY. 

1230 

60009  1231 
* Official support for "tt" style variants, via \isatt{...} or 
1232 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1233 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1234 
as argument to other macros (such as footnotes). 

1235 

1236 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1237 
style. 

1238 

1239 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1240 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1241 

59951  1242 
* Diagnostic commands and document markup commands within a proof do not 
1243 
affect the command tag for output. Thus commands like 'thm' are subject 

1244 
to proof document structure, and no longer "stick out" accidentally. 

1245 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1246 
tags. Potential INCOMPATIBILITY in exotic situations. 

1247 

1248 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1249 
which is also accessible via document antiquotation option "margin". 

1250 
Only the margin for document output may be changed, but not the global 

1251 
pretty printing: that is 76 for plain console output, and adapted 

1252 
dynamically in GUI frontends. Implementations of document 

1253 
antiquotations need to observe the margin explicitly according to 

1254 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

58310  1351 
 The old 'datatype' command has been renamed 'old_datatype', and 
58373  1352 
'rep_datatype' has been renamed 'old_rep_datatype'. They are 
1353 
provided by "~~/src/HOL/Library/Old_Datatype.thy". See 

58310  1354 
'isabelle doc datatypes' for information on porting.

* Nitpick: 
60010  1364 
 Fixed soundness bug related to the strict and nonstrict subset 
59039  1365 
operations. 
1366 

57737  1367 
* Sledgehammer: 
59511  1368 
 CVC4 is now included with Isabelle instead of CVC3 and run by 
1369 
default. 

59965  1370 
 Z3 is now always enabled by default, now that it is fully open 
1371 
source. The "z3_non_commercial" option is discontinued. 

57737  1372 
 Minimization is now always enabled by default. 
60010  1373 
Removed subcommand:

59967  1375 
 Proof reconstruction, both oneliners and Isar, has been 
59039  1376 
dramatically improved. 
1377 
 Improved support for CVC4 and veriT. 

57737  1378 

58062  1379 
* Old and new SMT modules: 
58067  1380 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1381 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1382 
until applications have been ported to use the new 'smt' method. For 

1383 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1384 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1385 
point to it. 

58062  1386 
INCOMPATIBILITY. 
58067  1387 
 The 'smt2' method has been renamed 'smt'. 
58060  1388 
INCOMPATIBILITY. 
59569  1389 
 New option 'smt_reconstruction_step_timeout' to limit the 
1390 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1391 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1392 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1393 

60261  1394 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1395 
that have as a return type a datatype containing a subtype. This 

1396 
overcomes longtime limitations in the area of code generation and 

1397 
lifting, and avoids tedious workarounds. 

60258  1398 

60009  1399 
* Command and antiquotation "value" provide different evaluation slots 
1400 
(again), where the previous strategy (NBE after ML) serves as default. 

1401 
Minor INCOMPATIBILITY.
