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

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.

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

204 
only appropriate when targets are managed, e.g. starting from a global 

205 
theory and returning to it. Regular definitional packages should use 

206 
balanced blocks of Local_Theory.open_target versus 

207 
Local_Theory.close_target instead. Rare INCOMPATIBILITY.

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

321 
'SML_file_no_debug' control compilation of sources with or without 

322

323

324

325

330

* The text overview column (status of errors, warnings etc.) is updated 
337 
asynchronously, leading to much better editor reactivity. Moreover, the 

338 
full document node content is taken into account. The width of the 

339 
column is scaled according to the main text area font, for improved 

340 
visibility. 

341 

342 
* The main text area no longer changes its color hue in outdated 

343 
situations. The text overview column takes over the role to indicate 

344 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

345 
due to adhoc updates by auxiliary GUI components, such as the State 

346 
panel.

466 

60449  467 
The local assumptions are bound to the name "that". The result is 
468 
exported from context of the statement as usual. The above roughly 

60414  469 
corresponds to a raw proof block like this: 
470

61733  481 
* Assumptions ('assume', 'presume') allow structured rule statements 
482 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  483 

484 
assume result: "C x y" 

485 
if "A x" and "B y" 

486 
for x :: 'a and y :: 'a 

487 

488 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

489 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

490 

491 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

492 
only effects propositions according to actual use of variables. For 

493 
example: 

494 

495 
assume "A x" and "B y" for x and y 

496 

497 
is equivalent to: 

498 

499 
assume "\<And>x. A x" and "\<And>y. B y" 

500 

60595  501 
* The meaning of 'show' with Pure rule statements has changed: premises 
502 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  503 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
504 
follows: 

60595  505 

506 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

507 

508 
or: 

509 

510 
show "C x" if "A x" "B x" for x 

511 

512 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

513 

514 
show "C x" when "A x" "B x" for x 

515 

60459  516 
* New command 'consider' states rules for generalized elimination and 
517 
case splitting. This is like a toplevel statement "theorem obtains" used 

518 
within a proof body; or like a multibranch 'obtain' without activation 

519 
of the local context elements yet. 

520 

60455  521 
* Proof method "cases" allows to specify the rule as first entry of 
522 
chained facts. This is particularly useful with 'consider': 

523 

524 
consider (a) A  (b) B  (c) C <proof> 

525 
then have something 

526 
proof cases 

527

528 
then show ?thesis <proof> 

529

530

536 

60565  537 
* Command 'case' allows fact name and attribute specification like this: 
538 

539 
case a: (c xs) 

540 
case a [attributes]: (c xs) 

541 

542 
Facts that are introduced by invoking the case context are uniformly 

543 
qualified by "a"; the same name is used for the cumulative fact. The old 

544 
form "case (c xs) [attributes]" is no longer supported. Rare 

545 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

546 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
554 
the initial backwards refinement is retained for the whole proof, within 

555 
all its context sections (as indicated via 'next'). This is e.g. 

556 
relevant for 'using', 'including', 'supply':

statements: result is abstracted over unknowns.

60631  575 
* Command 'subgoal' allows to impose some structure on backward

* Abstract specification of gcd/lcm operations in classes semiring_gcd, 
62017  882 
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute 
883 
and gcd_int.commute are subsumed by gcd.commute, as well as 

884 
gcd_nat.assoc and gcd_int.assoc by gcd.assoc.

* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are 

887 
logically unified to Rings.divide in syntactic type class Rings.divide, 

888 
with infix syntax (_ div _). Infix syntax (_ / _) for field division is 

889 
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY, 

890 
instantiations must refer to Rings.divide rather than the former 

891 
separate constants, hence infix syntax (_ / _) is usually not available 

892 
during instantiation.

* New cancellation simprocs for boolean algebras to cancel complementary 

895

896

*** Document preparation *** 
1197 

1198 
* Document markup commands 'chapter', 'section', 'subsection', 

1199 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1200 
context, even before the initial 'theory' command. Obsolete proof 

1201 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1202 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1203 
instead. The old 'header' command is still retained for some time, but 

1204 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1205 
update_header"). Minor INCOMPATIBILITY. 

1206 

60009  1207 
* Official support for "tt" style variants, via \isatt{...} or 
1208 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1209 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1210 
as argument to other macros (such as footnotes). 

1211 

1212 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1213 
style. 

1214 

1215 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1216 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1217 

59951  1218 
* Diagnostic commands and document markup commands within a proof do not 
1219 
affect the command tag for output. Thus commands like 'thm' are subject 

1220 
to proof document structure, and no longer "stick out" accidentally. 

1221 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1222 
tags. Potential INCOMPATIBILITY in exotic situations. 

1223 

1224 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1225 
which is also accessible via document antiquotation option "margin". 

1226 
Only the margin for document output may be changed, but not the global 

1227 
pretty printing: that is 76 for plain console output, and adapted 

1228 
dynamically in GUI frontends. Implementations of document 

1229 
antiquotations need to observe the margin explicitly according to 

1230 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* Sledgehammer: 
59511  1344 
 CVC4 is now included with Isabelle instead of CVC3 and run by 
1345 
default. 

59965  1346 
 Z3 is now always enabled by default, now that it is fully open 
1347 
source. The "z3_non_commercial" option is discontinued. 

57737  1348 
 Minimization is now always enabled by default.

 Proof reconstruction, both oneliners and Isar, has been 
59039  1352 
dramatically improved. 
1353 
 Improved support for CVC4 and veriT.

* Old and new SMT modules: 
58067  1356 
 The old 'smt' method has been renamed 'old_smt' and moved to 
59569  1357 
'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1358 
until applications have been ported to use the new 'smt' method. For 

1359 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1360 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1361 
point to it. 

58062  1362 
INCOMPATIBILITY. 
58067  1363 
 The 'smt2' method has been renamed 'smt'. 
58060  1364 
INCOMPATIBILITY. 
59569  1365 
 New option 'smt_reconstruction_step_timeout' to limit the 
1366 
reconstruction time of Z3 proof steps in the new 'smt' method. 

59216  1367 
 New option 'smt_statistics' to display statistics of the new 'smt' 
1368 
method, especially runtime statistics of Z3 proof reconstruction.

* Lifting: command 'lift_definition' allows to execute lifted constants 
1371 
that have as a return type a datatype containing a subtype. This 

1372 
overcomes longtime limitations in the area of code generation and 

1373 
lifting, and avoids tedious workarounds. 

60258  1374 

60009  1375 
* Command and antiquotation "value" provide different evaluation slots 
1376 
(again), where the previous strategy (NBE after ML) serves as default. 

1377 
Minor INCOMPATIBILITY. 

1378 

1379 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1380 

1381 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1382 
nontermination in case of distributing a division. With this change 

1383 
field_simps is in some cases slightly less powerful, if it fails try to 

1384 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1385 

1386 
* Separate class no_zero_divisors has been given up in favour of fully 

1387 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

1388 

1389 
* Class linordered_semidom really requires no zero divisors. 

1390 
INCOMPATIBILITY. 

1391 

1392 
* Classes division_ring, field and linordered_field always demand 

1393 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

1394 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY. 

1395 

1396 
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit 

1397 
additive inverse operation. INCOMPATIBILITY.

* Complex powers and square roots. The functions "ln" and "powr" are now 
60025  1400 
overloaded for types real and complex, and 0 powr y = 0 by definition. 
1401 
INCOMPATIBILITY: type constraints may be necessary.
