* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER 
27 
(and thus refers to something like $HOME/.isabelle/IsabelleXXXX), 

28 
while the default heap location within that directory lacks that extra 

29 
suffix. This isolates multiple Isabelle installations from each 

30 
other, avoiding problems with old settings in new versions.

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

149 
examples. 

150 

41398  151 
* Scala (2.8 or higher) has been added to the target languages of the 
152 
code generator. 

153 

154 
* Inductive package: offers new command 'inductive_simps' to 

155 
automatically derive instantiated and simplified equations for 

156 
inductive predicates, similar to 'inductive_cases'. 

157 

158 
* Function package: .psimps rules are no longer implicitly declared 

159 
[simp]. INCOMPATIBILITY. 

160 

161 
* Datatype package: theorems generated for executable equality (class 

162 
eq) carry proper names and are treated as default code equations. 

163 

41397  164 
* New command 'type_lifting' allows to register properties on 
165 
the functorial structure of types. 

166 

41398  167 
* Weaker versions of the "meson" and "metis" proof methods are now 
168 
available in "HOLPlain", without dependency on "Hilbert_Choice". The 

169 
proof methods become more powerful after "Hilbert_Choice" is loaded in 

170 
"HOLMain". 

39771  171 

39644  172 
* Improved infrastructure for term evaluation using code generator 
173 
techniques, in particular static evaluation conversions. 

174 

41398  175 
* Code generator: globbing constant expressions "*" and "Theory.*" 
176 
have been replaced by the more idiomatic "_" and "Theory._". 

177 
INCOMPATIBILITY. 

178 

179 
* Code generator: export_code without explicit file declaration prints 

180 
to standard output. INCOMPATIBILITY. 

181 

182 
* Code generator: do not print function definitions for case 

183 
combinators any longer. 

184 

185 
* Simplification with rules determined by code generator 

186 
with code_simp.ML and method code_simp. 

187 

188 
* Records: logical foundation type for records does not carry a '_type' 

40948  189 
suffix any longer. INCOMPATIBILITY. 
190 

191 
* Code generation for records: more idiomatic representation of record 

192 
types. Warning: records are not covered by ancient SML code 

193 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

194 
rep_datatype declaration helps to succeed then: 

38537  195 

196 
record 'a foo = ... 

197 
... 

198 
rep_datatype foo_ext ... 

38535  199 

41398  200 
* Quickcheck now by default uses exhaustive testing instead of random 
201 
testing. Random testing can be invoked by quickcheck[random], 

202 
exhaustive testing by quickcheck[exhaustive]. 

203 

204 
* Quickcheck instantiates polymorphic types with small finite 

205 
datatypes by default. This enables a simple execution mechanism to 

206 
handle quantifiers and function equality over the finite datatypes. 

207 

208 
* Quickcheck's generator for random generation is renamed from "code" 

209 
to "random". INCOMPATIBILITY. 

210 

211 
* Quickcheck now has a configurable time limit which is set to 30 

212 
seconds by default. This can be changed by adding [timeout = n] to the 

213 
quickcheck command. The time limit for Auto Quickcheck is still set 

214 
independently. 

38461  215 

216 
* Quickcheck in locales considers interpretations of that locale for 

217 
counter example search.

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

303 
finite type. Finite cartesian products of euclidean spaces, products 

304 
of euclidean spaces the real and complex numbers are instantiated to 

305

308 
Use pextreal as value for measures. Introduce the RadonNikodym 

309 
derivative, product spaces and Fubini's theorem for arbitrary sigma 

310 
finite measures. Introduces Lebesgue measure based on the integral in

483 
* The domain package now runs in definitional mode by default: The 

484 
former command 'new_domain' is now called 'domain'. To use the domain 

485 
package in its original axiomatic mode, use 'domain (unsafe)'. 

486 
INCOMPATIBILITY. 

487 

41401  488 
* The new class 'domain' is now the default sort. Class 'predomain' is 
489 
an unpointed version of 'domain'. Theories can be updated by replacing 

490 
sort annotations as shown below. INCOMPATIBILITY. 

40621  491 

492 
'a::type ~> 'a::countable 

493 
'a::cpo ~> 'a::predomain 

494 
'a::pcpo ~> 'a::domain 

495 

496 
* The old type class 'rep' has been superseded by class 'domain'. 

497 
Accordingly, users of the definitional package must remove any 

498 
'default_sort rep' declarations. INCOMPATIBILITY. 

499 

41401  500 
* The domain package (definitional mode) now supports unpointed 
501 
predomain argument types, as long as they are marked 'lazy'. (Strict 

502 
arguments must be in class 'domain'.) For example, the following 

503 
domain definition now works: 

504 

505 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

506 

507 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

508 
instances for types from Isabelle/HOL: bool, nat, int, char, 'a + 'b, 

509 
'a option, and 'a list. Additionally, it configures fixrec and the 

510 
domain package to work with these types. For example: 

511 

512 
fixrec isInl :: "('a + 'b) u > tr" 

513 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

514 

515 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

516 

517 
* The '(permissive)' option of fixrec has been replaced with a 

518 
perequation '(unchecked)' option. See HOLCF/Tutorial/Fixrec_ex.thy 

519 
for examples. INCOMPATIBILITY.

* Authentic syntax for *all* logical entities (type classes, type 
733 
constructors, term constants): provides simple and robust 

734 
correspondence between formal entities and concrete syntax. Within 

735 
the parse tree / AST representations, "constants" are decorated by 

736 
their category (class, type, const) and spelled out explicitly with 

737 
their full internal name. 

738 

739 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

740 
and translations (translation rules and translation functions in ML). 

741 
Some hints on upgrading: 

35260  742 

743 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  744 
by more modern 'type_notation', 'notation' and 'abbreviation', 
745 
which are independent of this issue. 

35260  746 

747 
 'translations' require markup within the AST; the term syntax 

748 
provides the following special forms: 

749 

750 
CONST c  produces syntax version of constant c from context 

35261  751 
XCONST c  literally c, checked as constant from context 
752 
c  literally c, if declared by 'syntax' 

753 

754 
Plain identifiers are treated as AST variables  occasionally the 

755 
system indicates accidental variables via the error "rhs contains 

756 
extra variables". 

35260  757 

35436  758 
Type classes and type constructors are marked according to their 
759 
concrete syntax. Some old translations rules need to be written 

760 
for the "type" category, using type constructor application 

761 
instead of pseudoterm application of the default category 

762 
"logic". 

763 

35260  764 
 'parse_translation' etc. in ML may use the following 
765 
antiquotations: 

766 

35436  767 
@{class_syntax c}  type class c within parse tree / AST 
768 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  769 
@{const_syntax c}  ML version of "CONST c" above 
770 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

771 

35436  772 
 Literal types within 'typed_print_translations', i.e. those *not* 
773 
represented as pseudoterms are represented verbatim. Use @{class 

774 
c} or @{type_name c} here instead of the above syntax 

775 
antiquotations. 

776 

35260  777 
Note that old nonauthentic syntax was based on unqualified base 
35436  778 
names, so all of the above "constant" names would coincide. Recall 
779 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

780 
diagnose syntax problems.

882 
* New package for quotient types. Commands 'quotient_type' and 

883 
'quotient_definition' may be used for defining types and constants by 

884 
quotient constructions. An example is the type of integers created by 

885 
quotienting pairs of natural numbers: 

37380  886 

37351  887 
fun 
37380  888 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  889 
where 
890 
"intrel (x, y) (u, v) = (x + v = u + y)" 

891 

37380  892 
quotient_type int = "nat * nat" / intrel 
37351  893

37380  894 

37351  895 
quotient_definition 
896 
"0::int" is "(0::nat, 0::nat)" 

897 

898 
The method "lifting" can be used to lift of theorems from the 

899 
underlying "raw" type to the quotient type. The example 

900 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

901 
construction and provides a reasoning infrastructure for finite sets. 

902 

903 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

904 
clash with new theory Quotient in Main HOL.

* Moved the SMT binding into the main HOL session, eliminating 

907

* Theory "Complete_Lattice": lemmas top_def and bot_def have been 
36416  1083 
replaced by the more convenient lemmas Inf_empty and Sup_empty. 
1084 
Dropped lemmas Inf_insert_simp and Sup_insert_simp, which are subsumed 

1085 
by Inf_insert and Sup_insert. Lemmas Inf_UNIV and Sup_UNIV replace 

1086 
former Inf_Univ and Sup_Univ. Lemmas inf_top_right and sup_bot_right

1162 
 Modified the Isar proof reconstruction code so that it produces 

1163

1165 
 Made Isar proof reconstruction work for SPASS, remote ATPs, and in

* Variable names in lemmas generated by the domain package have 

1212 
changed; the naming scheme is now consistent with the HOL datatype 

1213 
package. Some proof scripts may be affected, INCOMPATIBILITY. 

1214 

1215 
* The domain package no longer defines the function "foo_copy" for 

1216 
recursive domain "foo". The reach lemma is now stated directly in 

1217 
terms of "foo_take". Lemmas and proofs that mention "foo_copy" must 

1218 
be reformulated in terms of "foo_take", INCOMPATIBILITY. 

1219 

1220 
* Most definedness lemmas generated by the domain package (previously 

1221 
of the form "x ~= UU ==> foo$x ~= UU") now have an ifandonlyif form 

1222 
like "foo$x = UU <> x = UU", which works better as a simp rule. 

37351  1223

potential INCOMPATIBILITY.

1228 
constructor). INCOMPATIBILITY. 

1229

@{nonterminal NAME}  type of concrete syntactic category

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

1276 

1277 
@{const_name NAME}  logical constant (INCOMPATIBILITY) 

1278 
@{const_abbrev NAME}  abbreviated constant 

1279 
@{const_syntax NAME}  syntax representation of any of the above 

1280 

1281 
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw 

1282 
syntax constant (cf. 'syntax' command). 

1283 

1284 
* Antiquotation @{make_string} inlines a function to print arbitrary 

1285 
values similar to the ML toplevel. The result is compiler dependent 

1286 
and may fall back on "?" in certain situations. 

1287 

1288 
* Diagnostic commands 'ML_val' and 'ML_command' may refer to 

1289 
antiquotations @{Isar.state} and @{Isar.goal}. This replaces impure 

1290 
Isar.state() and Isar.goal(), which belong to the old TTY loop and do 

1291 
not work with the asynchronous Isar document model. 

1292 

1293 
* Configuration options now admit dynamic default values, depending on 

1294 
the context or even global references. 

1295 

1296 
* 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. 

1315 

1316 
* Most operations that refer to a global context are named 

1317 
accordingly, e.g. Simplifier.global_context or 

1318 
ProofContext.init_global. There are some situations where a global 

1319 
context actually works, but under normal circumstances one needs to 

1320 
pass the proper local context through the code! 

1321 

1322 
* Discontinued old TheoryDataFun with its copy/init operation  data 

1323

* "IsabelleText" is a Unicode font derived from Bitstream Vera Mono 
1381 
and Bluesky TeX fonts. It provides the usual Isabelle symbols, 

1382 
similar to the default assignment of the document preparation system 

1383 
(cf. isabellesym.sty). The Isabelle/Scala class Isabelle_System 

1384 
provides some operations for direct access to the font without asking 

1385 
the user for manual installation.
