* 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. 

31 
INCOMPATIBILITY, need to copy/upgrade old user settings manually.

* New command 'partial_function' provides basic support for recursive 
40194  149 
function definitions over complete partial orders. Concrete instances 
40183  150 
are provided for i) the option type, ii) tail recursion on arbitrary 
151 
types, and iii) the heap monad of Imperative_HOL. See 

152 
HOL/ex/Fundefs.thy and HOL/Imperative_HOL/ex/Linked_Lists.thy for 

153 
examples. 

154 

41398  155 
* Scala (2.8 or higher) has been added to the target languages of the 
156 
code generator. 

157 

158 
* Inductive package: offers new command 'inductive_simps' to 

159 
automatically derive instantiated and simplified equations for 

160 
inductive predicates, similar to 'inductive_cases'. 

161 

162 
* Function package: .psimps rules are no longer implicitly declared 

163 
[simp]. INCOMPATIBILITY. 

164 

165 
* Datatype package: theorems generated for executable equality (class 

166 
eq) carry proper names and are treated as default code equations. 

167 

41397  168 
* New command 'type_lifting' allows to register properties on 
169 
the functorial structure of types. 

170 

41398  171 
* Weaker versions of the "meson" and "metis" proof methods are now 
172 
available in "HOLPlain", without dependency on "Hilbert_Choice". The 

173 
proof methods become more powerful after "Hilbert_Choice" is loaded in 

174 
"HOLMain". 

39771  175 

39644  176 
* Improved infrastructure for term evaluation using code generator 
177 
techniques, in particular static evaluation conversions. 

178 

41398  179 
* Code generator: globbing constant expressions "*" and "Theory.*" 
180 
have been replaced by the more idiomatic "_" and "Theory._". 

181 
INCOMPATIBILITY. 

182 

183 
* Code generator: export_code without explicit file declaration prints 

184 
to standard output. INCOMPATIBILITY. 

185 

186 
* Code generator: do not print function definitions for case 

187 
combinators any longer. 

188 

189 
* Simplification with rules determined by code generator 

190 
with code_simp.ML and method code_simp. 

191 

192 
* Records: logical foundation type for records does not carry a '_type' 

40948  193 
suffix any longer. INCOMPATIBILITY. 
194 

195 
* Code generation for records: more idiomatic representation of record 

196 
types. Warning: records are not covered by ancient SML code 

197 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

198 
rep_datatype declaration helps to succeed then: 

38537  199 

200 
record 'a foo = ... 

201 
... 

202 
rep_datatype foo_ext ... 

38535  203 

41398  204 
* Quickcheck now by default uses exhaustive testing instead of random 
205 
testing. Random testing can be invoked by quickcheck[random], 

206 
exhaustive testing by quickcheck[exhaustive]. 

207 

208 
* Quickcheck instantiates polymorphic types with small finite 

209 
datatypes by default. This enables a simple execution mechanism to 

210 
handle quantifiers and function equality over the finite datatypes. 

211 

212 
* Quickcheck's generator for random generation is renamed from "code" 

213 
to "random". INCOMPATIBILITY. 

214 

215 
* Quickcheck now has a configurable time limit which is set to 30 

216 
seconds by default. This can be changed by adding [timeout = n] to the 

217 
quickcheck command. The time limit for Auto Quickcheck is still set 

218 
independently. 

38461  219 

220 
* Quickcheck in locales considers interpretations of that locale for 

221 
counter example search.

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

504 
former command 'new_domain' is now called 'domain'. To use the domain 

505 
package in its original axiomatic mode, use 'domain (unsafe)'. 

506 
INCOMPATIBILITY. 

507 

41401  508 
* The new class 'domain' is now the default sort. Class 'predomain' is 
509 
an unpointed version of 'domain'. Theories can be updated by replacing 

510 
sort annotations as shown below. INCOMPATIBILITY. 

40621  511

513 
'a::cpo ~> 'a::predomain

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

516 
* The old type class 'rep' has been superseded by class 'domain'. 

517 
Accordingly, users of the definitional package must remove any 

518 
'default_sort rep' declarations. INCOMPATIBILITY. 

519 

41401  520 
* The domain package (definitional mode) now supports unpointed 
521 
predomain argument types, as long as they are marked 'lazy'. (Strict 

522 
arguments must be in class 'domain'.) For example, the following 

523 
domain definition now works: 

524 

525 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

526 

527 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

528 
instances for types from Isabelle/HOL: bool, nat, int, char, 'a + 'b, 

529 
'a option, and 'a list. Additionally, it configures fixrec and the 

530 
domain package to work with these types. For example: 

531 

532 
fixrec isInl :: "('a + 'b) u > tr" 

533 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

534 

535 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

536 

537 
* The '(permissive)' option of fixrec has been replaced with a 

538 
perequation '(unchecked)' option. See HOLCF/Tutorial/Fixrec_ex.thy 

539 
for examples. INCOMPATIBILITY.

35436  759 
* Authentic syntax for *all* logical entities (type classes, type 
760 
constructors, term constants): provides simple and robust 

761 
correspondence between formal entities and concrete syntax. Within 

762 
the parse tree / AST representations, "constants" are decorated by 

763 
their category (class, type, const) and spelled out explicitly with 

764 
their full internal name. 

765 

766 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

767 
and translations (translation rules and translation functions in ML). 

768 
Some hints on upgrading: 

35260  769 

770 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  771 
by more modern 'type_notation', 'notation' and 'abbreviation', 
772 
which are independent of this issue. 

35260  773 

774 
 'translations' require markup within the AST; the term syntax 

775 
provides the following special forms: 

776 

777 
CONST c  produces syntax version of constant c from context 

35261  778 
XCONST c  literally c, checked as constant from context 
779 
c  literally c, if declared by 'syntax' 

780 

781 
Plain identifiers are treated as AST variables  occasionally the 

782 
system indicates accidental variables via the error "rhs contains 

783 
extra variables". 

35260  784 

35436  785 
Type classes and type constructors are marked according to their 
786 
concrete syntax. Some old translations rules need to be written 

787 
for the "type" category, using type constructor application 

788 
instead of pseudoterm application of the default category 

789 
"logic". 

790 

35260  791 
 'parse_translation' etc. in ML may use the following 
792 
antiquotations: 

793 

35436  794 
@{class_syntax c}  type class c within parse tree / AST 
795 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  796 
@{const_syntax c}  ML version of "CONST c" above 
797 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

798 

35436  799 
 Literal types within 'typed_print_translations', i.e. those *not* 
800 
represented as pseudoterms are represented verbatim. Use @{class 

801 
c} or @{type_name c} here instead of the above syntax 

802 
antiquotations. 

803 

35260  804 
Note that old nonauthentic syntax was based on unqualified base 
35436  805 
names, so all of the above "constant" names would coincide. Recall 
806 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

807 
diagnose syntax problems.

* Command 'typedef' now works within a local theory context  without 
904 
introducing dependencies on parameters or assumptions, which is not 

905 
possible in Isabelle/Pure/HOL. Note that the logical environment may 

906 
contain multiple interpretations of local typedefs (with different 

907 
nonemptiness proofs), even in a global theory context. 

908 

909 
* New package for quotient types. Commands 'quotient_type' and 

910 
'quotient_definition' may be used for defining types and constants by 

911 
quotient constructions. An example is the type of integers created by 

912 
quotienting pairs of natural numbers: 

37380  913 

37351  914 
fun 
37380  915 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  916 
where 
917 
"intrel (x, y) (u, v) = (x + v = u + y)" 

918 

37380  919 
quotient_type int = "nat * nat" / intrel 
37351  920 
by (auto simp add: equivp_def expand_fun_eq) 
37380  921 

37351  922 
quotient_definition 
923 
"0::int" is "(0::nat, 0::nat)" 

924 

925 
The method "lifting" can be used to lift of theorems from the 

926 
underlying "raw" type to the quotient type. The example 

927 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

928 
construction and provides a reasoning infrastructure for finite sets. 

929 

930 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

931 
clash with new theory Quotient in Main HOL.

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

1240 
package. Some proof scripts may be affected, INCOMPATIBILITY. 

1241 

1242 
* The domain package no longer defines the function "foo_copy" for 

1243 
recursive domain "foo". The reach lemma is now stated directly in 

1244 
terms of "foo_take". Lemmas and proofs that mention "foo_copy" must

1246 

1247 
* Most definedness lemmas generated by the domain package (previously 

1248 
of the form "x ~= UU ==> foo$x ~= UU") now have an ifandonlyif form 

1249 
like "foo$x = UU <> x = UU", which works better as a simp rule.

constructor). INCOMPATIBILITY.

@{class NAME}  type class

@{class_syntax NAME}  syntax representation of the above

@{const_abbrev NAME}  abbreviated constant

1309 
syntax constant (cf. 'syntax' command). 

1310 

1311 
* Antiquotation @{make_string} inlines a function to print arbitrary 

1312 
values similar to the ML toplevel. The result is compiler dependent 

1313

1314 

1315 
* Diagnostic commands 'ML_val' and 'ML_command' may refer to 

1316 
antiquotations @{Isar.state} and @{Isar.goal}. This replaces impure 

1317 
Isar.state() and Isar.goal(), which belong to the old TTY loop and do 

1318 
not work with the asynchronous Isar document model.

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

1341 
to remove it again will complicate porting again in the future.

1343 
* Most operations that refer to a global context are named 

1344 
accordingly, e.g. Simplifier.global_context or 

1345 
ProofContext.init_global. There are some situations where a global 

1346 
context actually works, but under normal circumstances one needs to 

1347 
pass the proper local context through the code! 

1348 

1349 
* Discontinued old TheoryDataFun with its copy/init operation  data 

1350 
needs to be pure. Functor Theory_Data_PP retains the traditional 

1351 
Pretty.pp argument to merge, which is absent in the standard 

1352 
Theory_Data version.

* Sorts.certify_sort and derived "cert" operations for types and terms 
1355 
no longer minimize sorts. Thus certification at the boundary of the 

1356 
inference kernel becomes invariant under addition of class relations, 

1357 
which is an important monotonicity principle. Sorts are now minimized 

1358 
in the syntax layer only, at the boundary between the enduser and the 

1359 
system. Subtle INCOMPATIBILITY, may have to use Sign.minimize_sort 

1360 
explicitly in rare situations.

1410 
(cf. isabellesym.sty). The Isabelle/Scala class Isabelle_System 

1411 
provides some operations for direct access to the font without asking 

1412 
the user for manual installation.
