* Experimental Prover IDE based on Isabelle/Scala and jEdit (see

executable Isabelle tool.

* Significantly improved Isabelle/Isar implementation manual.

* Source files are always encoded as UTF8, instead of oldfashioned 
16 
ISOLatin1. INCOMPATIBILITY. Isabelle LaTeX documents might require 

40948  17

* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER 
31 
(and thus refers to something like $HOME/.isabelle/IsabelleXXXX), 

32 
while the default heap location within that directory lacks that extra 

33 
suffix. This isolates multiple Isabelle installations from each 

34 
other, avoiding problems with old settings in new versions. 

35 
INCOMPATIBILITY, need to copy/upgrade old user settings manually.

* Command 'partial_function' provides basic support for recursive 
176 
function definitions over complete partial orders. Concrete instances 

40183  177 
are provided for i) the option type, ii) tail recursion on arbitrary 
41571  178 
types, and iii) the heap monad of Imperative_HOL. See 
179 
src/HOL/ex/Fundefs.thy and src/HOL/Imperative_HOL/ex/Linked_Lists.thy 

180 
for examples. 

40183  181 

41398  182 
* Scala (2.8 or higher) has been added to the target languages of the 
183 
code generator. 

184 

41571  185 
* Inductive package: now offers command 'inductive_simps' to 
41398  186 
automatically derive instantiated and simplified equations for 
187 
inductive predicates, similar to 'inductive_cases'. 

188 

41571  189 
* Function package: f.psimps rules are no longer implicitly declared 
190 
as [simp]. INCOMPATIBILITY. 

41398  191 

192 
* Datatype package: theorems generated for executable equality (class 

41571  193 
"eq") carry proper names and are treated as default code equations. 
194 

195 
* Command 'enriched_type' allows to register properties of the 

196 
functorial structure of types. 

39771  197 

39644  198 
* Improved infrastructure for term evaluation using code generator 
199 
techniques, in particular static evaluation conversions. 

200 

41398  201 
* Code generator: globbing constant expressions "*" and "Theory.*" 
202 
have been replaced by the more idiomatic "_" and "Theory._". 

203 
INCOMPATIBILITY. 

204 

205 
* Code generator: export_code without explicit file declaration prints 

206 
to standard output. INCOMPATIBILITY. 

207 

208 
* Code generator: do not print function definitions for case 

209 
combinators any longer. 

210 

41571  211 
* Simplification with rules determined by code generator with 
212 
src/Tools/Code/code_simp.ML and method "code_simp". 

213 

214 
* Records: logical foundation type for records does not carry a 

215 
'_type' suffix any longer (obsolete due to authentic syntax). 

216 
INCOMPATIBILITY. 

40948  217 

218 
* Code generation for records: more idiomatic representation of record 

219 
types. Warning: records are not covered by ancient SML code 

220 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

221 
rep_datatype declaration helps to succeed then: 

38537  222 

223 
record 'a foo = ... 

224 
... 

225 
rep_datatype foo_ext ... 

38535  226 

41398  227 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  228 
testing. Random testing can be invoked by "quickcheck [random]", 
229 
exhaustive testing by "quickcheck [exhaustive]". 

41398  230 

231 
* Quickcheck instantiates polymorphic types with small finite 

232 
datatypes by default. This enables a simple execution mechanism to 

233 
handle quantifiers and function equality over the finite datatypes. 

234 

41571  235 
* Quickcheck random generator has been renamed from "code" to 
236 
"random". INCOMPATIBILITY. 

41398  237 

238 
* Quickcheck now has a configurable time limit which is set to 30 

239 
seconds by default. This can be changed by adding [timeout = n] to the 

240 
quickcheck command. The time limit for Auto Quickcheck is still set 

241 
independently. 

38461  242 

243 
* Quickcheck in locales considers interpretations of that locale for 

244 
counter example search.

279 
to diagnose these tools. E.g. 

280 

281

282 

41398  283

284 
manually as command 'solve_direct'. 

285 

41571  286 
* The default SMT solver is now CVC3. Z3 must be enabled explicitly 
287 
(due to licensing issues) via Z3_NON_COMMERCIAL in etc/settings of the 

288

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

335 
finite type. Finite cartesian products of euclidean spaces, products 

336 
of euclidean spaces the real and complex numbers are instantiated to 

337

41571  339 
* Session Probability: Introduced pextreal as positive extended real 
340 
numbers. Use pextreal as value for measures. Introduce the 

341 
RadonNikodym derivative, product spaces and Fubini's theorem for 

342 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

343

various improvements. INCOMPATIBILITY. 

355 

41571  356 
* Theory Library/Multiset provides stable quicksort implementation of 
41398  357 
sort_key.

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

41571  510 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  511 
package in its original axiomatic mode, use 'domain (unsafe)'. 
512 
INCOMPATIBILITY. 

513 

41571  514 
* The new class "domain" is now the default sort. Class "predomain" 
515 
is an unpointed version of "domain". Theories can be updated by 

516 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  517 

518 
'a::type ~> 'a::countable 

519 
'a::cpo ~> 'a::predomain 

520 
'a::pcpo ~> 'a::domain 

521 

41571  522 
* The old type class "rep" has been superseded by class "domain". 
40621  523 
Accordingly, users of the definitional package must remove any 
41571  524 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  525 

41401  526 
* The domain package (definitional mode) now supports unpointed 
527 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  528 
arguments must be in class "domain".) For example, the following 
41401  529 
domain definition now works: 
530 

531 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

532 

533 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  534 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
535 
'a option, and 'a list. Additionally, it configures fixrec and the 

536 
domain package to work with these types. For example: 

41401  537 

538 
fixrec isInl :: "('a + 'b) u > tr" 

539 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

540 

541 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

542 

41571  543 
* The "(permissive)" option of fixrec has been replaced with a 
544 
perequation "(unchecked)" option. See 

545 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

546 

547 
* The "bifinite" class no longer fixes a constant "approx"; the class 

548

549 

550 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

561 
* The function "cprod_map" has been renamed to "prod_map". 

41401  562 
INCOMPATIBILITY. 
563 

564 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  565 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
566 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  567 

568 
* The infix syntax for binary union on each powerdomain has changed 

41571  569 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
570

41571  599 

600 
 Definitions of "bisim" constants no longer mention definedness. 

601 
 With mutual recursion, "bisim" predicate is now curried.

35436  762 
* Authentic syntax for *all* logical entities (type classes, type 
763 
constructors, term constants): provides simple and robust 

764 
correspondence between formal entities and concrete syntax. Within 

765 
the parse tree / AST representations, "constants" are decorated by 

766 
their category (class, type, const) and spelled out explicitly with 

767 
their full internal name. 

768 

769 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

770 
and translations (translation rules and translation functions in ML). 

771 
Some hints on upgrading: 

35260  772 

773 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  774 
by more modern 'type_notation', 'notation' and 'abbreviation', 
775 
which are independent of this issue. 

35260  776 

777 
 'translations' require markup within the AST; the term syntax 

778 
provides the following special forms: 

779 

780 
CONST c  produces syntax version of constant c from context 

35261  781 
XCONST c  literally c, checked as constant from context 
782 
c  literally c, if declared by 'syntax' 

783 

784 
Plain identifiers are treated as AST variables  occasionally the 

785 
system indicates accidental variables via the error "rhs contains 

786 
extra variables". 

35260  787 

35436  788 
Type classes and type constructors are marked according to their 
789 
concrete syntax. Some old translations rules need to be written 

790 
for the "type" category, using type constructor application 

791 
instead of pseudoterm application of the default category 

792 
"logic". 

793 

35260  794 
 'parse_translation' etc. in ML may use the following 
795 
antiquotations: 

796 

35436  797 
@{class_syntax c}  type class c within parse tree / AST 
798 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  799 
@{const_syntax c}  ML version of "CONST c" above 
800 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

801 

35436  802 
 Literal types within 'typed_print_translations', i.e. those *not* 
803 
represented as pseudoterms are represented verbatim. Use @{class 

804 
c} or @{type_name c} here instead of the above syntax 

805 
antiquotations. 

806 

35260  807 
Note that old nonauthentic syntax was based on unqualified base 
35436  808 
names, so all of the above "constant" names would coincide. Recall 
809 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

810 
diagnose syntax problems.

912 
* New package for quotient types. Commands 'quotient_type' and 

913 
'quotient_definition' may be used for defining types and constants by 

914 
quotient constructions. An example is the type of integers created by 

915 
quotienting pairs of natural numbers:

fun 
37380  918 
intrel :: "(nat * nat) => (nat * nat) => bool"

"0::int" is "(0::nat, 0::nat)" 

927 

928 
The method "lifting" can be used to lift of theorems from the 

929 
underlying "raw" type to the quotient type. The example 

930 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

931 
construction and provides a reasoning infrastructure for finite sets.

* Theory "Complete_Lattice": lemmas top_def and bot_def have been 
36416  1113 
replaced by the more convenient lemmas Inf_empty and Sup_empty. 
1114 
Dropped lemmas Inf_insert_simp and Sup_insert_simp, which are subsumed 

1115

1191

1192 
 Modified the Isar proof reconstruction code so that it produces 

1193 
direct proofs rather than proofs by contradiction. (This feature 

1194 
is still experimental.) 

1195 
 Made Isar proof reconstruction work for SPASS, remote ATPs, and in 

1196 
fulltyped mode. 

1197

 Added support for "specification" and "ax_specification" 

1206

1241 
* Variable names in lemmas generated by the domain package have 

1242 
changed; the naming scheme is now consistent with the HOL datatype 

1243 
package. Some proof scripts may be affected, INCOMPATIBILITY. 

1244 

1245 
* The domain package no longer defines the function "foo_copy" for 

1246 
recursive domain "foo". The reach lemma is now stated directly in 

1247 
terms of "foo_take". Lemmas and proofs that mention "foo_copy" must 

1248 
be reformulated in terms of "foo_take", INCOMPATIBILITY. 

1249 

1250 
* Most definedness lemmas generated by the domain package (previously 

1251 
of the form "x ~= UU ==> foo$x ~= UU") now have an ifandonlyif form 

1252 
like "foo$x = UU <> x = UU", which works better as a simp rule. 

37351  1253 
Proofs that used definedness lemmas as intro rules may break,

potential INCOMPATIBILITY. 
1255

* Induction and casedist rules generated by the domain package now

1258 
constructor). INCOMPATIBILITY. 

1259

@{nonterminal NAME}  type of concrete syntactic category

@{type_syntax NAME}  syntax representation of any of the above 

1306 

1307 
@{const_name NAME}  logical constant (INCOMPATIBILITY) 

1308 
@{const_abbrev NAME}  abbreviated constant 

1309 
@{const_syntax NAME}  syntax representation of any of the above 

1310 

1311 
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw 

1312 
syntax constant (cf. 'syntax' command). 

1313 

1314 
* Antiquotation @{make_string} inlines a function to print arbitrary 

1315 
values similar to the ML toplevel. The result is compiler dependent 

1316 
and may fall back on "?" in certain situations. 

1317 

1318 
* Diagnostic commands 'ML_val' and 'ML_command' may refer to 

1319 
antiquotations @{Isar.state} and @{Isar.goal}. This replaces impure 

1320 
Isar.state() and Isar.goal(), which belong to the old TTY loop and do 

1321 
not work with the asynchronous Isar document model. 

1322 

1323 
* Configuration options now admit dynamic default values, depending on 

1324 
the context or even global references. 

1325 

1326 
* SHA1.digest digests strings according to SHA1 (see RFC 3174). It

Note that "open Legacy" simplifies porting of sources, but forgetting

to remove it again will complicate porting again in the future. 

1345 

1346 
* Most operations that refer to a global context are named 

1347 
accordingly, e.g. Simplifier.global_context or 

1348 
ProofContext.init_global. There are some situations where a global 

1349 
context actually works, but under normal circumstances one needs to 

1350 
pass the proper local context through the code! 

1351 

1352 
* Discontinued old TheoryDataFun with its copy/init operation  data 

1353 
needs to be pure. Functor Theory_Data_PP retains the traditional 

1354

* Sorts.certify_sort and derived "cert" operations for types and terms 
1358 
no longer minimize sorts. Thus certification at the boundary of the 

1359 
inference kernel becomes invariant under addition of class relations, 

1360 
which is an important monotonicity principle. Sorts are now minimized 

1361 
in the syntax layer only, at the boundary between the enduser and the 

1362

1363
