* Obsolete command 'types' has been discontinued. Use 'type_synonym' 

10 
instead. INCOMPATIBILITY. 

11 

45191  12 
* Ancient code generator for SML and its commands 'code_module', 
13 
'code_library', 'consts_code', 'types_code' have been discontinued. 

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

45134  15 

45122  16 
*** HOL *** 
17 

45143  18 
* 'Transitive_Closure.ntrancl': bounded transitive closure on relations. 
19 

20 
* 'sublists' moved to More_List.thy; INCOMPATIBILITY. 

21 

45122  22 
* Theory Int: Discontinued many legacy theorems specific to type int. 
23 
INCOMPATIBILITY, use the corresponding generic theorems instead.

distinctions at the same time: E.g. 

62 

63 
list.exhaust[case_product nat.exhaust] 

64

84 

44760  85 
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as 
44968  86 
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  87 

44777  88 
 Management of multiple theory files directly from the editor 
44760  89 
buffer store  bypassing the filesystem (no requirement to save 
90 
files for checking). 

91 

44777  92 
 Markup of formal entities within the text buffer, with semantic 
44760  93 
highlighting, tooltips and hyperlinks to jump to defining source 
94 
positions. 

95 

44777  96 
 Improved text rendering, with sub/superscripts in the source 
97 
buffer (including support for copy/paste wrt. output panel, HTML 

98 
theory output and other nonIsabelle text boxes). 

99 

100 
 Refined scheduling of proof checking and printing of results, 

44760  101 
based on interactive editor view. (Note: jEdit folding and 
102 
narrowing allows to restrict buffer perspectives explicitly.) 

103 

44777  104 
 Reduced CPU performance requirements, usable on machines with few 
44760  105 
cores. 
106 

44777  107 
 Reduced memory requirements due to pruning of unused document 
44760  108 
versions (garbage collection). 
109 

110 
See also ~~/src/Tools/jEdit/README.html for further information, 

111 
including some remaining limitations. 

112 

44800  113 
* Theory loader: source files are exclusively located via the master 
114 
directory of each theory node (where the .thy file itself resides). 

115 
The global load path (such as src/HOL/Library) has been discontinued. 

116 
Note that the path element ~~ may be used to reference theories in the 

117 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet". 

118 
INCOMPATIBILITY.

* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`. Note 
140 
that the result needs to be unique, which means fact specifications 

141 
may have to be refined after enriching a proof context. 

142 

44800  143 
* Attribute "case_names" has been refined: the assumptions in each case 
144 
can be named now by following the case name with [name1 name2 ...]. 

145 

44968  146 
* Isabelle/Isar reference manual has been updated and extended: 
147 
 "Synopsis" provides a catalog of main Isar language concepts. 

148 
 Formal references in syntax diagrams, via @{rail} antiquotation. 

149 
 Updated material from classic "ref" manual, notably about 

150 
"Classical Reasoner".

* Added syntactic classes "inf" and "sup" for the respective 
217 
constants. INCOMPATIBILITY: Changes in the argument order of the 

218 
(mostly internal) locale predicates for some derived classes. 

219 

44800  220 
* Theorem collections ball_simps and bex_simps do not contain theorems 
221 
referring to UNION any longer; these have been moved to collection 

222 
UN_ball_bex_simps. INCOMPATIBILITY. 

223 

224 
* Theory Archimedean_Field: floor now is defined as parameter of a 

225 
separate type class floor_ceiling.

* New proof method "induction" that gives induction hypotheses the 
363 
name "IH", thus distinguishing them from further hypotheses that come 

364 
from rule induction. The latter are still called "hyps". Method 

365 
"induction" is a thin wrapper around "induct" and follows the same 

366 
syntax. 

367 

44968  368 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
369 
still available as a legacy feature for some time. 

370 

371 
* Nitpick: 

372 
 Added "need" and "total_consts" options. 

373 
 Reintroduced "show_skolems" option by popular demand. 

374 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

375 
INCOMPATIBILITY. 

376 

377 
* Sledgehammer: 

378 
 Use quasisound (and efficient) translations by default. 

379 
 Added support for the following provers: EToFoF, LEOII, 

380 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

381 
 Automatically preplay and minimize proofs before showing them if 

382 
this can be done within reasonable time. 

383 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

384 
INCOMPATIBILITY. 

385 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

386 
"max_mono_iters", and "max_new_mono_instances" options. 

387 
 Removed "explicit_apply" and "full_types" options as well as "Full 

388 
Types" Proof General menu item. INCOMPATIBILITY. 

389 

390

392 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

393 
INCOMPATIBILITY. 

394 

395 
* Command 'try': 

396 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

397 
"elim:" options. INCOMPATIBILITY. 

398 
 Introduced 'try' that not only runs 'try_methods' but also 

399 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

400 

401 
* Quickcheck: 

402 
 Added "eval" option to evaluate terms for the found counterexample 

403 
(currently only supported by the default (exhaustive) tester). 

404 
 Added postprocessing of terms to obtain readable counterexamples 

405 
(currently only supported by the default (exhaustive) tester). 

406 
 New counterexample generator quickcheck[narrowing] enables 

407 
narrowingbased testing. Requires the Glasgow Haskell compiler 

408 
with its installation location defined in the Isabelle settings 

409 
environment as ISABELLE_GHC. 

410 
 Removed quickcheck tester "SML" based on the SML code generator 

411 
(formly in HOL/Library). 

412 

413 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

414 
use 'partial_function' instead. 

415 

416 
* Theory Library/Extended_Reals replaces now the positive extended 

417 
reals found in probability theory. This file is extended by 

418 
Multivariate_Analysis/Extended_Real_Limits. 

419 

44974  420 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
421 
from where it must be imported explicitly if it is really required. 

422 
INCOMPATIBILITY. 

44968  423 

424 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

425 
been moved here. INCOMPATIBILITY. 

426 

427 
* Theory Library/Saturated provides type of numbers with saturated 

428 
arithmetic. 

429 

430 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

431 
product type 'a * 'b, and provides instance proofs for various order 

432 
and lattice type classes. 

433 

434 
* Theory Library/Countable now provides the "countable_datatype" proof 

435 
method for proving "countable" class instances for datatypes. 

436 

437 
* Theory Library/Cset_Monad allows do notation for computable sets 

438 
(cset) via the generic monad adhoc overloading facility. 

439 

440 
* Library: Theories of common data structures are split into theories 

441 
for implementation, an invariantensuring type, and connection to an 

442 
abstract type. INCOMPATIBILITY. 

443 

444 
 RBT is split into RBT and RBT_Mapping. 

445 
 AssocList is split and renamed into AList and AList_Mapping. 

446 
 DList is split into DList_Impl, DList, and DList_Cset. 

447 
 Cset is split into Cset and List_Cset. 

448 

449 
* Theory Library/Nat_Infinity has been renamed to 

450 
Library/Extended_Nat, with name changes of the following types and 

451 
constants: 

452 

453 
type inat ~> type enat 

454 
Fin ~> enat 

455 
Infty ~> infinity (overloaded) 

456 
iSuc ~> eSuc 

457 
the_Fin ~> the_enat 

458 

459 
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has 

460 
been renamed accordingly. INCOMPATIBILITY. 

461 

462 
* Session Multivariate_Analysis: The euclidean_space type class now 

463 
fixes a constant "Basis :: 'a set" consisting of the standard 

464 
orthonormal basis for the type. Users now have the option of 

465 
quantifying over this set instead of using the "basis" function, e.g. 

466 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

467 

468 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

469 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

470 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

471 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

472 
changed to match. Definition theorems for overloaded constants now use 

473 
the standard "foo_vec_def" naming scheme. A few other theorems have 

474 
been renamed as follows (INCOMPATIBILITY): 

475 

476 
Cart_eq ~> vec_eq_iff 

477 
dist_nth_le_cart ~> dist_vec_nth_le 

478 
tendsto_vector ~> vec_tendstoI 

479 
Cauchy_vector ~> vec_CauchyI 

480 

481 
* Session Multivariate_Analysis: Several duplicate theorems have been 

482 
removed, and other theorems have been renamed or replaced with more 

483

661 
without proper multithreading and TimeLimit implementation. 

662

* Various optional external tools are referenced more robustly and 
667

670 
ISABELLE_GHC (formerly EXEC_GHC or GHC_PATH) 

671

* Scala layer provides JVM method invocation service for static 
44800  679 
methods of type (String)String, see Invoke_Scala.method in ML. For 
680

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

683

* Command 'partial_function' provides basic support for recursive 
864 
function definitions over complete partial orders. Concrete instances 

40183  865 
are provided for i) the option type, ii) tail recursion on arbitrary 
41571  866 
types, and iii) the heap monad of Imperative_HOL. See 
867 
src/HOL/ex/Fundefs.thy and src/HOL/Imperative_HOL/ex/Linked_Lists.thy 

868 
for examples. 

40183  869 

41571  870 
* Function package: f.psimps rules are no longer implicitly declared 
871 
as [simp]. INCOMPATIBILITY. 

41398  872 

873 
* Datatype package: theorems generated for executable equality (class 

41571  874 
"eq") carry proper names and are treated as default code equations. 
875 

41594  876 
* Inductive package: now offers command 'inductive_simps' to 
877 
automatically derive instantiated and simplified equations for 

878 
inductive predicates, similar to 'inductive_cases'. 

879 

41571  880 
* Command 'enriched_type' allows to register properties of the 
881 
functorial structure of types. 

39771  882 

39644  883 
* Improved infrastructure for term evaluation using code generator 
884 
techniques, in particular static evaluation conversions. 

885 

41594  886 
* Code generator: Scala (2.8 or higher) has been added to the target 
887 
languages. 

888 

41398  889 
* Code generator: globbing constant expressions "*" and "Theory.*" 
890 
have been replaced by the more idiomatic "_" and "Theory._". 

891 
INCOMPATIBILITY. 

892 

893 
* Code generator: export_code without explicit file declaration prints 

894 
to standard output. INCOMPATIBILITY. 

895 

896 
* Code generator: do not print function definitions for case 

897 
combinators any longer. 

898 

41594  899 
* Code generator: simplification with rules determined with 
41571  900 
src/Tools/Code/code_simp.ML and method "code_simp". 
901 

41594  902 
* Code generator for records: more idiomatic representation of record 
40948  903 
types. Warning: records are not covered by ancient SML code 
904 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

905 
rep_datatype declaration helps to succeed then: 

38537  906 

907 
record 'a foo = ... 

908 
... 

909 
rep_datatype foo_ext ... 

38535  910 

41594  911 
* Records: logical foundation type for records does not carry a 
912 
'_type' suffix any longer (obsolete due to authentic syntax). 

913 
INCOMPATIBILITY. 

914 

41398  915 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  916 
testing. Random testing can be invoked by "quickcheck [random]", 
917 
exhaustive testing by "quickcheck [exhaustive]". 

41398  918 

919 
* Quickcheck instantiates polymorphic types with small finite 

920 
datatypes by default. This enables a simple execution mechanism to 

921 
handle quantifiers and function equality over the finite datatypes. 

922 

41571  923 
* Quickcheck random generator has been renamed from "code" to 
924 
"random". INCOMPATIBILITY. 

41398  925 

926 
* Quickcheck now has a configurable time limit which is set to 30 

927 
seconds by default. This can be changed by adding [timeout = n] to the 

928 
quickcheck command. The time limit for Auto Quickcheck is still set 

929 
independently. 

38461  930 

931 
* Quickcheck in locales considers interpretations of that locale for 

932 
counter example search.

975 
licensing issues) by setting the environment variable 

41603  976 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
977 
commercial applications, the SMT solver CVC3 is provided as fallback;

INCOMPATIBILITY. Note that these were not supposed to be used 

1111 
regularly unless for striking reasons; their main purpose was code 

1112 
generation. 

1113 

1114 
Various operations from the Haskell prelude are used for generating 

1115 
Haskell code. 

1116 

41571  1117 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
1118 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

1119 
bij_def and surj_def are unchanged. INCOMPATIBILITY. 

41398  1120 

1121 
* Abolished some nonalphabetic type names: "prod" and "sum" replace 

1122 
"*" and "+" respectively. INCOMPATIBILITY. 

1123 

1124 
* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  1125 
"Sum_Type.Plus" instead. 
41398  1126 

1127 
* Constant "split" has been merged with constant "prod_case"; names of 

1128 
ML functions, facts etc. involving split have been retained so far, 

1129 
though. INCOMPATIBILITY. 

1130 

1131 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

1132 
instead. INCOMPATIBILITY. 

1133 

41571  1134 
* Removed lemma "Option.is_none_none" which duplicates "is_none_def". 
41398  1135 
INCOMPATIBILITY. 
1136 

41594  1137 
* Former theory Library/Enum is now part of the HOLMain image. 
1138 
INCOMPATIBILITY: all constants of the Enum theory now have to be 

1139

product ~> Enum.product 

1144 

1145 
* Theory Library/Monad_Syntax provides dosyntax for monad types. 

1146 
Syntax in Library/State_Monad has been changed to avoid ambiguities. 

1147 
INCOMPATIBILITY. 

1148 

1149 
* Theory Library/SetsAndFunctions has been split into 

1150 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

1151 
for instance definitions for functions; various improvements. 

1152 
INCOMPATIBILITY. 

1153 

1154 
* Theory Library/Multiset provides stable quicksort implementation of 

1155 
sort_key. 

1156 

1157 
* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

1158 
INCOMPATIBILITY. 

1159 

1160 
* Session Multivariate_Analysis: introduced a type class for euclidean 

1161 
space. Most theorems are now stated in terms of euclidean spaces 

1162 
instead of finite cartesian products. 

1163 

1164 
types 

1165 
real ^ 'n ~> 'a::real_vector 

1166 
~> 'a::euclidean_space 

1167

_ $ _ ~> _ $$ _ 

1172 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

1173 
CARD('n) ~> DIM('a) 

1174 

1175 
Also note that the indices are now natural numbers and not from some 

1176 
finite type. Finite cartesian products of euclidean spaces, products 

1177 
of euclidean spaces the real and complex numbers are instantiated to 

1178 
be euclidean_spaces. INCOMPATIBILITY. 

1179 

1180 
* Session Probability: introduced pextreal as positive extended real 

1181 
numbers. Use pextreal as value for measures. Introduce the 

1182 
RadonNikodym derivative, product spaces and Fubini's theorem for 

1183 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

1184 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

1185 

1186 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

1187 
INCOMPATIBILITY. 

1188 

1189 
* Session SPARK (with image HOLSPARK) provides commands to load and 

1190 
prove verification conditions generated by the SPARK Ada program 

1191 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

1208 
* The domain package now runs in definitional mode by default: The 

41571  1209 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  1210 
package in its original axiomatic mode, use 'domain (unsafe)'. 
1211 
INCOMPATIBILITY. 

1212 

41571  1213 
* The new class "domain" is now the default sort. Class "predomain" 
1214 
is an unpointed version of "domain". Theories can be updated by 

1215 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  1216

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

1219 
'a::pcpo ~> 'a::domain 

1220 

41571  1221 
* The old type class "rep" has been superseded by class "domain". 
40621  1222 
Accordingly, users of the definitional package must remove any 
41571  1223 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  1224 

41401  1225 
* The domain package (definitional mode) now supports unpointed 
1226 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  1227 
arguments must be in class "domain".) For example, the following 
41401  1228 
domain definition now works: 
1229 

1230 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

1231 

1232 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  1233 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
1234 
'a option, and 'a list. Additionally, it configures fixrec and the 

1235 
domain package to work with these types. For example: 

41401  1236 

1237 
fixrec isInl :: "('a + 'b) u > tr" 

1238 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

1239 

1240 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

1241 

41571  1242 
* The "(permissive)" option of fixrec has been replaced with a 
1243 
perequation "(unchecked)" option. See 

1244 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

1245 

1246 
* The "bifinite" class no longer fixes a constant "approx"; the class 

1247 
now just asserts that such a function exists. INCOMPATIBILITY. 

1248 

1249 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

1253 

1254

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

1257 

1258 
* The type class "finite_po" has been removed. INCOMPATIBILITY. 

1259 

1260 
* The function "cprod_map" has been renamed to "prod_map". 

41401  1261 
INCOMPATIBILITY. 
1262 

1263 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  1264 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
1265 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  1266 

1267 
* The infix syntax for binary union on each powerdomain has changed 

41571  1268 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
1269 
syntax. INCOMPATIBILITY. 

1270

1300 
 With mutual recursion, "bisim" predicate is now curried.
