14 
Use commands of the generic code generator instead. INCOMPATIBILITY. 

45134  15 

45233  16 
* Redundant attribute 'code_inline' has been discontinued. Use 'code_unfold' 
17 
instead. INCOMPATIBILITY.

45122  19 
*** HOL *** 
20 

45143  21 
* 'Transitive_Closure.ntrancl': bounded transitive closure on relations. 
22 

45210  23 
* 'Set.not_member' now qualifed. INCOMPATIBILITY. 
24 

25 
* 'sublists' moved to More_List.thy. INCOMPATIBILITY. 

45143  26 

45122  27 
* Theory Int: Discontinued many legacy theorems specific to type int. 
28 
INCOMPATIBILITY, use the corresponding generic theorems instead.

distinctions at the same time: E.g. 

67 

68 
list.exhaust[case_product nat.exhaust] 

69

89 

44760  90 
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as 
44968  91 
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  92 

44777  93 
 Management of multiple theory files directly from the editor 
44760  94 
buffer store  bypassing the filesystem (no requirement to save 
95 
files for checking). 

96 

44777  97 
 Markup of formal entities within the text buffer, with semantic 
44760  98 
highlighting, tooltips and hyperlinks to jump to defining source 
99 
positions. 

100 

44777  101 
 Improved text rendering, with sub/superscripts in the source 
102 
buffer (including support for copy/paste wrt. output panel, HTML 

103 
theory output and other nonIsabelle text boxes). 

104 

105 
 Refined scheduling of proof checking and printing of results, 

44760  106 
based on interactive editor view. (Note: jEdit folding and 
107 
narrowing allows to restrict buffer perspectives explicitly.) 

108 

44777  109 
 Reduced CPU performance requirements, usable on machines with few 
44760  110 
cores. 
111 

44777  112 
 Reduced memory requirements due to pruning of unused document 
44760  113 
versions (garbage collection). 
114 

115 
See also ~~/src/Tools/jEdit/README.html for further information, 

116 
including some remaining limitations. 

117 

44800  118 
* Theory loader: source files are exclusively located via the master 
119 
directory of each theory node (where the .thy file itself resides). 

120 
The global load path (such as src/HOL/Library) has been discontinued. 

121 
Note that the path element ~~ may be used to reference theories in the 

122 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet". 

123 
INCOMPATIBILITY.

* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`. Note 
145 
that the result needs to be unique, which means fact specifications 

146 
may have to be refined after enriching a proof context. 

147 

44800  148 
* Attribute "case_names" has been refined: the assumptions in each case 
149 
can be named now by following the case name with [name1 name2 ...]. 

150 

44968  151 
* Isabelle/Isar reference manual has been updated and extended: 
152 
 "Synopsis" provides a catalog of main Isar language concepts. 

153 
 Formal references in syntax diagrams, via @{rail} antiquotation. 

154 
 Updated material from classic "ref" manual, notably about 

155 
"Classical Reasoner".

complete boolean algebras and complete linear orders. Lemmas 

166 
Inf_less_iff, less_Sup_iff, INF_less_iff, less_SUP_iff now reside in

reactivated by the following theory command: 

362 

363 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

364 

365 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

366 

45088  367 
* New proof method "induction" that gives induction hypotheses the 
368 
name "IH", thus distinguishing them from further hypotheses that come 

369 
from rule induction. The latter are still called "hyps". Method 

370 
"induction" is a thin wrapper around "induct" and follows the same 

371 
syntax. 

372 

44968  373 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
374 
still available as a legacy feature for some time. 

375 

376 
* Nitpick: 

377 
 Added "need" and "total_consts" options. 

378 
 Reintroduced "show_skolems" option by popular demand. 

379 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

380 
INCOMPATIBILITY. 

381 

382 
* Sledgehammer: 

383 
 Use quasisound (and efficient) translations by default. 

384 
 Added support for the following provers: EToFoF, LEOII, 

385 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

386 
 Automatically preplay and minimize proofs before showing them if 

387 
this can be done within reasonable time. 

388 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

389 
INCOMPATIBILITY. 

390 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

391 
"max_mono_iters", and "max_new_mono_instances" options. 

392 
 Removed "explicit_apply" and "full_types" options as well as "Full 

393 
Types" Proof General menu item. INCOMPATIBILITY. 

394 

395 
* Metis: 

396 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

397 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

398 
INCOMPATIBILITY. 

399 

400 
* Command 'try': 

401 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

402 
"elim:" options. INCOMPATIBILITY. 

403 
 Introduced 'try' that not only runs 'try_methods' but also 

404 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

405 

406 
* Quickcheck: 

407 
 Added "eval" option to evaluate terms for the found counterexample 

408 
(currently only supported by the default (exhaustive) tester). 

409 
 Added postprocessing of terms to obtain readable counterexamples 

410 
(currently only supported by the default (exhaustive) tester). 

411 
 New counterexample generator quickcheck[narrowing] enables 

412 
narrowingbased testing. Requires the Glasgow Haskell compiler 

413 
with its installation location defined in the Isabelle settings 

414 
environment as ISABELLE_GHC. 

415 
 Removed quickcheck tester "SML" based on the SML code generator 

416 
(formly in HOL/Library). 

417 

418 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

419 
use 'partial_function' instead. 

420 

421 
* Theory Library/Extended_Reals replaces now the positive extended 

422 
reals found in probability theory. This file is extended by 

423 
Multivariate_Analysis/Extended_Real_Limits. 

424 

44974  425 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
426 
from where it must be imported explicitly if it is really required. 

427 
INCOMPATIBILITY. 

44968  428 

429 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

430 
been moved here. INCOMPATIBILITY. 

431 

432 
* Theory Library/Saturated provides type of numbers with saturated 

433 
arithmetic. 

434 

435 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

436 
product type 'a * 'b, and provides instance proofs for various order 

437 
and lattice type classes. 

438 

439 
* Theory Library/Countable now provides the "countable_datatype" proof 

440 
method for proving "countable" class instances for datatypes. 

441 

442 
* Theory Library/Cset_Monad allows do notation for computable sets 

443 
(cset) via the generic monad adhoc overloading facility. 

444 

445 
* Library: Theories of common data structures are split into theories 

446 
for implementation, an invariantensuring type, and connection to an 

447 
abstract type. INCOMPATIBILITY. 

448 

449 
 RBT is split into RBT and RBT_Mapping. 

450 
 AssocList is split and renamed into AList and AList_Mapping. 

451 
 DList is split into DList_Impl, DList, and DList_Cset. 

452 
 Cset is split into Cset and List_Cset. 

453 

454 
* Theory Library/Nat_Infinity has been renamed to 

455 
Library/Extended_Nat, with name changes of the following types and 

456 
constants: 

457 

458 
type inat ~> type enat 

459 
Fin ~> enat 

460 
Infty ~> infinity (overloaded) 

461 
iSuc ~> eSuc 

462 
the_Fin ~> the_enat 

463 

464 
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has 

465 
been renamed accordingly. INCOMPATIBILITY. 

466 

467 
* Session Multivariate_Analysis: The euclidean_space type class now 

468 
fixes a constant "Basis :: 'a set" consisting of the standard 

469 
orthonormal basis for the type. Users now have the option of 

470 
quantifying over this set instead of using the "basis" function, e.g. 

471 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

472 

473 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

474 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

475 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

476 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

477 
changed to match. Definition theorems for overloaded constants now use 

478 
the standard "foo_vec_def" naming scheme. A few other theorems have 

479 
been renamed as follows (INCOMPATIBILITY): 

480 

481 
Cart_eq ~> vec_eq_iff 

482 
dist_nth_le_cart ~> dist_vec_nth_le 

483 
tendsto_vector ~> vec_tendstoI 

484 
Cauchy_vector ~> vec_CauchyI 

485 

486 
* Session Multivariate_Analysis: Several duplicate theorems have been 

487 
removed, and other theorems have been renamed or replaced with more 

488

* Classical tactics use proper Proof.context instead of historic types 
655 
claset/clasimpset. Oldstyle declarations like addIs, addEs, addDs 

656 
operate directly on Proof.context. Raw type claset retains its use as 

657 
snapshot of the classical context, which can be recovered via 

658 
(put_claset HOL_cs) etc. Type clasimpset has been discontinued. 

659 
INCOMPATIBILITY, classical tactics and derived proof methods require 

660

672

675 
ISABELLE_GHC (formerly EXEC_GHC or GHC_PATH) 

676

677 
ISABELLE_SWIPL (formerly EXEC_SWIPL) 

678 
ISABELLE_YAP (formerly EXEC_YAP)

680 
Note that automated detection from the filesystem or search path has 

681 
been discontinued. INCOMPATIBILITY.

* Scala layer provides JVM method invocation service for static 
44800  684 
methods of type (String)String, see Invoke_Scala.method in ML. For 
685 
example: 

43752  686 

687 
Invoke_Scala.method "java.lang.System.getProperty" "java.home" 

688 

44967  689 
Together with YXML.string_of_body/parse_body and XML.Encode/Decode 
690 
this allows to pass structured values between ML and Scala.

* The IsabelleText fonts includes some further glyphs to support the 
693 
Prover IDE. Potential INCOMPATIBILITY: users who happen to have 

694

695 
delete or update it from ~~/lib/fonts/.

* Coercive subtyping: functions can be declared as coercions and type 
850 
inference will add them as necessary upon input of a term. Theory 

851 
Complex_Main declares real :: nat => real and real :: int => real as 

852 
coercions. A coercion function f is declared like this:

* Command 'partial_function' provides basic support for recursive 
869 
function definitions over complete partial orders. Concrete instances 

40183  870 
are provided for i) the option type, ii) tail recursion on arbitrary 
41571  871 
types, and iii) the heap monad of Imperative_HOL. See 
872 
src/HOL/ex/Fundefs.thy and src/HOL/Imperative_HOL/ex/Linked_Lists.thy 

873 
for examples.

* Function package: f.psimps rules are no longer implicitly declared 
876 
as [simp]. INCOMPATIBILITY. 

41398  877 

878 
* Datatype package: theorems generated for executable equality (class 

41571  879 
"eq") carry proper names and are treated as default code equations. 
880 

41594  881 
* Inductive package: now offers command 'inductive_simps' to 
882 
automatically derive instantiated and simplified equations for 

883 
inductive predicates, similar to 'inductive_cases'. 

884 

41571  885 
* Command 'enriched_type' allows to register properties of the 
886 
functorial structure of types. 

39771  887 

39644  888 
* Improved infrastructure for term evaluation using code generator 
889 
techniques, in particular static evaluation conversions. 

890 

41594  891 
* Code generator: Scala (2.8 or higher) has been added to the target 
892 
languages. 

893 

41398  894 
* Code generator: globbing constant expressions "*" and "Theory.*" 
895 
have been replaced by the more idiomatic "_" and "Theory._".

INCOMPATIBILITY.

899 
to standard output. INCOMPATIBILITY.

* Code generator: do not print function definitions for case 

902 
combinators any longer. 

903 

41594  904 
* Code generator: simplification with rules determined with 
41571  905 
src/Tools/Code/code_simp.ML and method "code_simp". 
906 

41594  907 
* Code generator for records: more idiomatic representation of record 
40948  908 
types. Warning: records are not covered by ancient SML code 
909 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

910 
rep_datatype declaration helps to succeed then: 

38537  911 

912 
record 'a foo = ... 

913 
... 

914 
rep_datatype foo_ext ... 

38535  915 

41594  916 
* Records: logical foundation type for records does not carry a 
917 
'_type' suffix any longer (obsolete due to authentic syntax).

INCOMPATIBILITY.

41398  920 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  921 
testing. Random testing can be invoked by "quickcheck [random]", 
922 
exhaustive testing by "quickcheck [exhaustive]". 

41398  923 

924 
* Quickcheck instantiates polymorphic types with small finite 

925 
datatypes by default. This enables a simple execution mechanism to 

926 
handle quantifiers and function equality over the finite datatypes. 

927 

41571  928 
* Quickcheck random generator has been renamed from "code" to 
929 
"random". INCOMPATIBILITY. 

41398  930 

931 
* Quickcheck now has a configurable time limit which is set to 30 

932 
seconds by default. This can be changed by adding [timeout = n] to the 

933 
quickcheck command. The time limit for Auto Quickcheck is still set 

934 
independently. 

38461  935 

936 
* Quickcheck in locales considers interpretations of that locale for 

937 
counter example search.

980

Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
982 
commercial applications, the SMT solver CVC3 is provided as fallback;

1118 

1119 
Various operations from the Haskell prelude are used for generating 

1120 
Haskell code. 

1121 

41571  1122 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
1123 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

1124 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  1125 

1126 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

1127 
"*" and "+" respectively. INCOMPATIBILITY. 

1128 

1129 
* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  1130 
"Sum_Type.Plus" instead. 
41398  1131 

1132 
* Constant "split" has been merged with constant "prod_case"; names of 

1133 
ML functions, facts etc. involving split have been retained so far, 

1134 
though. INCOMPATIBILITY. 

1135 

1136 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

1137 
instead. INCOMPATIBILITY. 

1138 

41571  1139 
* Removed lemma "Option.is_none_none" which duplicates "is_none_def". 
41398  1140 
INCOMPATIBILITY. 
1141 

41594  1142 
* Former theory Library/Enum is now part of the HOLMain image. 
1143 
INCOMPATIBILITY: all constants of the Enum theory now have to be 

1144

product ~> Enum.product 

1149 

1150 
* Theory Library/Monad_Syntax provides dosyntax for monad types. 

1151 
Syntax in Library/State_Monad has been changed to avoid ambiguities. 

1152 
INCOMPATIBILITY. 

1153 

1154 
* Theory Library/SetsAndFunctions has been split into 

1155 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

1156 
for instance definitions for functions; various improvements. 

1157 
INCOMPATIBILITY. 

1158 

1159 
* Theory Library/Multiset provides stable quicksort implementation of 

1160 
sort_key. 

1161 

1162 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

1163 
INCOMPATIBILITY. 

1164 

1165 
* Session Multivariate_Analysis: introduced a type class for euclidean 

1166 
space. Most theorems are now stated in terms of euclidean spaces 

1167 
instead of finite cartesian products. 

1168 

1169 
types 

1170 
real ^ 'n ~> 'a::real_vector 

1171 
~> 'a::euclidean_space 

1172

_ $ _ ~> _ $$ _ 

1177 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

1178 
CARD('n) ~> DIM('a) 

1179 

1180 
Also note that the indices are now natural numbers and not from some 

1181 
finite type. Finite cartesian products of euclidean spaces, products 

1182 
of euclidean spaces the real and complex numbers are instantiated to 

1183 
be euclidean_spaces. INCOMPATIBILITY. 

1184 

1185 
* Session Probability: introduced pextreal as positive extended real 

1186 
numbers. Use pextreal as value for measures. Introduce the 

1187 
RadonNikodym derivative, product spaces and Fubini's theorem for 

1188 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

1189 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

1190 

1191 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

1192 
INCOMPATIBILITY. 

1193 

1194 
* Session SPARK (with image HOLSPARK) provides commands to load and 

1195 
prove verification conditions generated by the SPARK Ada program 

1196 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

1213 
* The domain package now runs in definitional mode by default: The 

41571  1214 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  1215 
package in its original axiomatic mode, use 'domain (unsafe)'. 
1216 
INCOMPATIBILITY. 

1217 

41571  1218 
* The new class "domain" is now the default sort. Class "predomain" 
1219 
is an unpointed version of "domain". Theories can be updated by 

1220 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  1221 

1222 
'a::type ~> 'a::countable 

1223 
'a::cpo ~> 'a::predomain 

1224 
'a::pcpo ~> 'a::domain 

1225 

41571  1226 
* The old type class "rep" has been superseded by class "domain". 
40621  1227 
Accordingly, users of the definitional package must remove any 
41571  1228 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  1229 

41401  1230 
* The domain package (definitional mode) now supports unpointed 
1231 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  1232 
arguments must be in class "domain".) For example, the following 
41401  1233 
domain definition now works: 
1234 

1235 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

1236 

1237 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  1238 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
1239 
'a option, and 'a list. Additionally, it configures fixrec and the 

1240 
domain package to work with these types. For example: 

41401  1241 

1242 
fixrec isInl :: "('a + 'b) u > tr" 

1243 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

1244 

1245 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

1246 

41571  1247 
* The "(permissive)" option of fixrec has been replaced with a 
1248 
perequation "(unchecked)" option. See 

1249 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

1250 

1251 
* The "bifinite" class no longer fixes a constant "approx"; the class 

1252 
now just asserts that such a function exists. INCOMPATIBILITY. 

1253 

1254 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

1258 

1259 
* The syntax "REP('a)" has been replaced with "DEFL('a)". 

1260 

1261 
* The predicate "directed" has been removed. INCOMPATIBILITY. 

1262 

1263 
* The type class "finite_po" has been removed. INCOMPATIBILITY. 

1264 

1265 
* The function "cprod_map" has been renamed to "prod_map". 

41401  1266 
INCOMPATIBILITY. 
1267 

1268 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  1269 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
1270 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  1271 

1272 
* The infix syntax for binary union on each powerdomain has changed 

41571  1273 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
1274 
syntax. INCOMPATIBILITY. 

1275

1305 
 With mutual recursion, "bisim" predicate is now curried.
