* (Co)datatype package: 

62332  27 
 the predicator :: ('a => bool) => 'a F => bool is now a firstclass 
28 
citizen in bounded natural functors 

62327  29 
 "primrec" now allows nested calls through the predicator in addition 
30 
to the map function. 

62332  31 
 "bnf" automatically discharges reflexive proof obligations 
32 
"bnf" outputs a slightly modified proof obligation expressing rel in 

33 
terms of map and set 

34 
(not giving a specification for rel makes this one reflexive) 

35 
"bnf" outputs a new proof obligation expressing pred in terms of set 

36 
(not giving a specification for pred makes this one reflexive) 

37 
INCOMPATIBILITY: manual "bnf" declarations may need adjustment 

62335  38 
 Renamed lemmas: 
39 
rel_prod_apply ~> rel_prod_inject 

40 
pred_prod_apply ~> pred_prod_inject 

41 
INCOMPATIBILITY. 

62327  42 

62407  43 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
44 
resemble the f.split naming convention, INCOMPATIBILITY.

* Option ML_exception_debugger controls detailed exception trace via the 

187 
Poly/ML debugger. Relevant ML modules need to be compiled beforehand 

188 
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note 

189 
debugger information requires consirable time and space: main 

190 
Isabelle/HOL with full debugger support may need ML_system_64. 

191

* Local_Theory.restore has been renamed to Local_Theory.reset to 
193 
emphasize its disruptive impact on the cumulative context, notably the 

194 
scope of 'private' or 'qualified' names. Note that Local_Theory.reset is 

195 
only appropriate when targets are managed, e.g. starting from a global 

196 
theory and returning to it. Regular definitional packages should use 

197 
balanced blocks of Local_Theory.open_target versus 

198 
Local_Theory.close_target instead. Rare INCOMPATIBILITY.

282

* The text overview column (status of errors, warnings etc.) is updated 
298 
asynchronously, leading to much better editor reactivity. Moreover, the 

299 
full document node content is taken into account. The width of the 

300 
column is scaled according to the main text area font, for improved 

301 
visibility. 

302 

303 
* The main text area no longer changes its color hue in outdated 

304 
situations. The text overview column takes over the role to indicate 

305 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

306 
due to adhoc updates by auxiliary GUI components, such as the State 

307 
panel.

61733  442 
* Assumptions ('assume', 'presume') allow structured rule statements 
443 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  444 

445 
assume result: "C x y" 

446 
if "A x" and "B y" 

447 
for x :: 'a and y :: 'a 

448 

449 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

450 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

451 

452 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

453 
only effects propositions according to actual use of variables. For 

454 
example: 

455 

456 
assume "A x" and "B y" for x and y 

457 

458 
is equivalent to: 

459 

460 
assume "\<And>x. A x" and "\<And>y. B y" 

461 

60595  462 
* The meaning of 'show' with Pure rule statements has changed: premises 
463 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  464 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
465 
follows: 

60595  466 

467 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

468 

469 
or: 

470 

471 
show "C x" if "A x" "B x" for x 

472 

473 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

474 

475 
show "C x" when "A x" "B x" for x 

476 

60459  477 
* New command 'consider' states rules for generalized elimination and 
478 
case splitting. This is like a toplevel statement "theorem obtains" used 

479 
within a proof body; or like a multibranch 'obtain' without activation 

480 
of the local context elements yet. 

481 

60455  482 
* Proof method "cases" allows to specify the rule as first entry of 
483 
chained facts. This is particularly useful with 'consider': 

484 

485 
consider (a) A  (b) B  (c) C <proof> 

486 
then have something 

487 
proof cases 

488 
case a 

489 
then show ?thesis <proof> 

490 
next 

491 
case b 

492 
then show ?thesis <proof> 

493 
next 

494 
case c 

495 
then show ?thesis <proof> 

496 
qed 

497 

60565  498 
* Command 'case' allows fact name and attribute specification like this: 
499 

500 
case a: (c xs) 

501 
case a [attributes]: (c xs) 

502 

503 
Facts that are introduced by invoking the case context are uniformly 

504 
qualified by "a"; the same name is used for the cumulative fact. The old 

505 
form "case (c xs) [attributes]" is no longer supported. Rare 

506 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

507 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
515 
the initial backwards refinement is retained for the whole proof, within 

516 
all its context sections (as indicated via 'next'). This is e.g. 

517 
relevant for 'using', 'including', 'supply': 

518

528 
proof body as well, abstracted over relevant parameters. 

529 

530 
* Improved typeinference for theorem statement 'obtains': separate 

531 
parameter scope for of each clause. 

532 

533 
* Term abbreviations via 'is' patterns also work for schematic 

534 
statements: result is abstracted over unknowns. 

535 

60631  536 
* Command 'subgoal' allows to impose some structure on backward 
537 
refinements, to avoid proof scripts degenerating into long of 'apply' 

538 
sequences. Further explanations and examples are given in the isarref 

539 
manual. 

540 

62017  541 
* Command 'supply' supports fact definitions during goal refinement 
542

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  569 
is marked as legacy, and will be removed eventually. The proof method 
570 
"goals" achieves a similar effect within regular Isar; often it can be 

571 
done more adequately by other means (e.g. 'consider').

'abbreviation' is also kept for morphims that only change the involved

parameters, and only 'notation' is suppressed. This can be of great help 
595 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
638 
"axiomatization", to a full definitional specification that takes the 

639 
global collection of overloaded constant / type definitions into 

640 
account. Type definitions with open dependencies on overloaded 

641 
definitions need to be specified as "typedef (overloaded)". This 

642 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

643 

644 
* Qualification of various formal entities in the libraries is done more 

645 
uniformly via "context begin qualified definition ... end" instead of 

646 
oldstyle "hide_const (open) ...". Consequently, both the defined 

647 
constant and its defining fact become qualified, e.g. Option.is_none and 

648 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

649 

650 
* Some old and rarely used ASCII replacement syntax has been removed. 

651 
INCOMPATIBILITY, standard syntax with symbols should be used instead.

679 

680 
* The alternative notation "\<Colon>" for type and sort constraints has been 

681 
removed: in LaTeX document output it looks the same as "::". 

682 
INCOMPATIBILITY, use plain "::" instead. 

683 

684 
* Commands 'inductive' and 'inductive_set' work better when names for 

685 
intro rules are omitted: the "cases" and "induct" rules no longer 

686 
declare empty case_names, but no case_names at all. This allows to use 

687 
numbered cases in proofs, without requiring method "goal_cases". 

688 

689 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

690 
lowlevel facts of the internal construction only if the option 

62093  691 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  692 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
693 

694 
* Recursive function definitions ('fun', 'function', 'partial_function') 

695 
expose lowlevel facts of the internal construction only if the option 

62205  696 
"function_internals" is enabled. Its internal inductive definition is 
697 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  698 

699 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

700 
of the internal construction only if the option "bnf_internals" is 

701 
enabled. This supersedes the former option "bnf_note_all". Rare 

702

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

754 
'real' is no longer overloaded, but has type 'nat => real' and 

755 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

756 
abbreviates of_int for that type. Other overloaded instances of 'real' 

757 
have been replaced by 'real_of_ereal' and 'real_of_float'.

* The following combinators for lowlevel profiling of the ML runtime 
954 
system are available: 

955 

956 
profile_time (*CPU time*) 

957 
profile_time_thread (*CPU time on this thread*)

* Antiquotation @{method NAME} inlines the (checked) name of the given 
963

964 

61922  965 
* Pretty printing of Poly/ML compiler output in Isabelle has been 
966 
improved: proper treatment of break offsets and blocks with consistent 

967 
breaks. 

968 

61268  969 
* The auxiliary module Pure/display.ML has been eliminated. Its 
970 
elementary thm print operations are now in Pure/more_thm.ML and thus 

971 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.

985 
Drule.infer_instantiate' (*version with positional arguments*) 

986 

987 
The LHS only requires variable specifications, instead of full terms. 

988 
Old cterm_instantiate is superseded by infer_instantiate. 

989 
INCOMPATIBILITY, need to readjust some ML names and types accordingly.

1103 
together with an attribute to maintain the content incrementally. This 

1104 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
1166 

1167 
* Document markup commands 'chapter', 'section', 'subsection', 

1168 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1169 
context, even before the initial 'theory' command. Obsolete proof 

1170 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1171 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1172 
instead. The old 'header' command is still retained for some time, but 

1173 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1174 
update_header"). Minor INCOMPATIBILITY. 

1175 

60010  1176 
* Official support for "tt" style variants, via \isatt{...} or 
1177 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1178 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1179 
as argument to other macros (such as footnotes). 

1180 

1181 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1182 
style. 

1183 

1184 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1185 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1186 

59951  1187 
* Diagnostic commands and document markup commands within a proof do not 
1188 
affect the command tag for output. Thus commands like 'thm' are subject 

1189 
to proof document structure, and no longer "stick out" accidentally. 

1190 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1191 
tags. Potential INCOMPATIBILITY in exotic situations. 

1192 

1193 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1194 
which is also accessible via document antiquotation option "margin". 

1195 
Only the margin for document output may be changed, but not the global 

1196 
pretty printing: that is 76 for plain console output, and adapted 

1197 
dynamically in GUI frontends. Implementations of document 

1198 
antiquotations need to observe the margin explicitly according to 

1199 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* The functions "sin" and "cos" are now defined for any type of sort 
1373 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

1374 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

1375 
needed. 

1376 

1377 
* New library of properties of the complex transcendental functions sin, 

1378 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1379 

1380 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1381 
that admits numeric types including nat, int, real and complex. 

1382 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1383 
constraint, and the combination "real (fact k)" is likely to be 

1384 
unsatisfactory. If a type conversion is still necessary, then use 

1385 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1386 

1387 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1388 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1389 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1390 
"nat_floor"/"nat_ceiling". 

1391 

1392 
* Qualified some duplicated fact names required for boostrapping the 

1393 
type class hierarchy: 

1394 
ab_add_uminus_conv_diff ~> diff_conv_add_uminus 

1395 
field_inverse_zero ~> inverse_zero
