* Renamed command 'print_configs' to 'print_options'. Minor 
16 
INCOMPATIBILITY. 

17 

51417  18 
* Sessions may be organized via 'chapter' specifications in the ROOT 
19 
file, which determines a twolevel hierarchy of browser info. The old 

20 
treelike organization via implicit subsession relation, with its 

21 
tendency towards erratic fluctuation of URLs, has been discontinued. 

22 
The default chapter is "Unsorted". Potential INCOMPATIBILITY for HTML

30 
'ML_file' in Isabelle2013. Minor INCOMPATIBILITY. 

31 

52415  32 
* Updated and extended "isarref" and "implementation" manual, 
33 
eliminated old "ref" manual. 

34 

52430  35 
* Proper diagnostic command 'print_state'. Old 'pr' (with its 
36 
implicit change of some global references) is retained for now as 

37 
control command, e.g. for ProofGeneral 3.7.x. 

38 

52549  39 
* Discontinued 'print_drafts' command with its oldfashioned PS output 
40 
and Unix commandline print spooling. Minor INCOMPATIBILITY: use 

41 
'display_drafts' instead and print via the regular document viewer.

* Execution range of continuous document processing may be set to 
47 
"all", "none", "visible". See also dockable window "Theories" or 

48 
keyboard shortcuts "Ce BACK_SPACE" for "none", and "Ce SPACE" for 

49 
"visible". These declarative options supersede the oldstyle action 

50 
buttons "Cancel" and "Check". 

51 

52646  52 
* Strictly monotonic document update, without premature cancelation of 
53 
running transactions that are still needed: avoid reset/restart of 

54 
such command executions while editing. 

55 

56 
* Support for asynchronous print functions, as overlay to existing 

57 
document content. 

58 

59 
* Support for automatic tools in HOL, which try to prove or disprove 

60 
toplevel theorem statements. 

61 

52445  62 
* Dockable window "Documentation" provides access to Isabelle 
63 
documentation.

* Type theory is now immutable, without any special treatment of 
74 
drafts or linear updates (which could lead to "stale theory" errors in 

75 
the past). Discontinued obsolete operations like Theory.copy, 

76 
Theory.checkpoint, and the auxiliary type theory_ref. Minor

85 
on Proof.context. Discontinued former "(advanced)" option  this is 

86 
now the default. Minor INCOMPATIBILITY. 

87 

51747  88 
* Targetsensitive commands 'interpretation' and 'sublocale'. 
89 
Particulary, 'interpretation' now allows for nonpersistent 

90 
interpretation within "context ... begin ... end" blocks. 

91 
See "isarref" manual for details. 

92 

51565  93 
* Improved locales diagnostic command 'print_dependencies'. 
94

96 
legacy since Isabelle20092. INCOMPATIBILITY, use 'axiomatization' 

97 
instead, while observing its uniform scope for polymorphism.

51682  138 
* Nested case expressions are now translated in a separate check 
139 
phase rather than during parsing. The data for case combinators 

140 
is separated from the datatype package. The declaration attribute 

141 
"case_translation" can be used to register new case combinators: 

142 

143 
declare [[case_translation case_combinator constructor1 ... constructorN]] 

144 

51596  145 
* Notation "{p:A. P}" now allows tuple patterns as well. 
146 

51489  147 
* Revised devices for recursive definitions over finite sets: 
148 
 Only one fundamental fold combinator on finite set remains: 

149 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

150 
This is now identity on infinite sets.

 Locales comm_monoid_set, semilattice_order_set and 

154 
semilattice_neutr_order_set for big operators on sets. 

155 
See theory Big_Operators for canonical examples. 

156 
Note that foundational constants comm_monoid_set.F and 

157 
semilattice_set.F correspond to former combinators fold_image 

158 
and fold1 respectively. These are now gone. You may use 

51490  159 
those foundational constants as substitutes, but it is 
51489  160 
preferable to interpret the above locales accordingly. 
161 
 Dropped class ab_semigroup_idem_mult (special case of lattice, 

162

 FDERIV: Definition of has_derivative moved to Deriv.thy. Moved theorems 

234 
from Library/FDERIV.thy to Deriv.thy and base the definition of DERIV on 

235 
FDERIV. Add variants of DERIV and FDERIV which are restricted to sets, 

236 
i.e. to represent derivatives from left or right. 

237

 Removed the withinfilter. It is replaced by the principal filter: 

239 

240 
F within X = inf F (principal X)

 Introduce "at x within U" as a single constant, "at x" is now an 

243 
abbreviation for "at x within UNIV" 

244 

245 
 Introduce named theorem collections tendsto_intros, continuous_intros, 

246 
continuous_on_intros and FDERIV_intros. Theorems in tendsto_intros (or 

247 
FDERIV_intros) are also available as tendsto_eq_intros (or 

248 
FDERIV_eq_intros) where the righthand side is replaced by a congruence 

249 
rule. This allows to apply them as intro rules and then proving 

250 
equivalence by the simplifier.

* Parallel terminal proofs ('by') are enabled by default, likewise 

408 
proofs that are built into packages like 'datatype', 'function'. This

surface, while the prover is still crunching on internal 

411 
justifications. Unfinished / cancelled proofs are restarted as 

412 
required to complete full proof checking eventually. 

413 

414 
* Improved output panel with tooltips, hyperlinks etc. based on the 

415 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

416 
tooltips leads to some window that supports the same recursively, 

417 
which can lead to stacks of tooltips as the semantic document content 

418 
is explored. ESCAPE closes the whole stack, individual windows may be 

419 
closed separately, or detached to become independent jEdit dockables. 

420

572 
expresses that when the input values x converge to F then the 

573 
output f x converges to G. 

574 

575

576 
infinity (at_bot). 

577 

578 
 Moved infinity in the norm (at_infinity) from 

579 
Multivariate_Analysis to Complex_Main.

597 
changes as follows. 

598 

599 
 Renamed constants (and related lemmas) 

49145  600 

601 
prefix ~> prefixeq 

602 
strict_prefix ~> prefix 

603 

50646  604 
 Replaced constant "postfix" by "suffixeq" with swapped argument 
605 
order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped 

606 
old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead. 

607 
Renamed lemmas accordingly. 

608 

609 
 Added constant "list_hembeq" for homeomorphic embedding on 

610 
lists. Added abbreviation "sublisteq" for special case 

611 
"list_hembeq (op =)". 

612 

613 
 Theory Library/Sublist no longer provides "order" and "bot" type 

614 
class instances for the prefix order (merely corresponding locale 

615 
interpretations). The type class instances are now in theory 

616 
Library/Prefix_Order. 

617 

618 
 The sublist relation of theory Library/Sublist_Order is now based 

619 
on "Sublist.sublisteq". Renamed lemmas accordingly:

641 

642 
* Theory Library/Debug and Library/Parallel provide debugging and 

643 
parallel execution for code generated towards Isabelle/ML. 

644 

645 
* Theory Library/FuncSet: Extended support for Pi and extensional and 

646 
introduce the extensional dependent function space "PiE". Replaced 

647 
extensional_funcset by an abbreviation, and renamed lemmas from 

648 
extensional_funcset to PiE as follows: 

649 

650 
extensional_empty ~> PiE_empty 

651 
extensional_funcset_empty_domain ~> PiE_empty_domain 

652 
extensional_funcset_empty_range ~> PiE_empty_range

663 
* Theory Library/FinFun: theory of almost everywhere constant 

664 
functions (supersedes the AFP entry "Code Generation for Functions as 

665 
Data"). 

666 

667 
* Theory Library/Phantom: generic phantom type to make a type 

668 
parameter appear in a constant's type. This alternative to adding 

669 
TYPE('a) as another parameter avoids unnecessary closures in generated 

670 
code. 

671 

672 
* Theory Library/RBT_Impl: efficient construction of redblack trees 

673 
from sorted associative lists. Merging two trees with rbt_union may 

674 
return a structurally different tree than before. Potential 

675 
INCOMPATIBILITY. 

676 

677 
* Theory Library/IArray: immutable arrays with code generation. 

678 

679 
* Theory Library/Finite_Lattice: theory of finite lattices. 

680 

681 
* HOL/Multivariate_Analysis: replaced

* Bundled declarations associate attributed fact expressions with a 
879 
given name in the context. These may be later included in other 

880 
contexts. This allows to manage context extensions casually, without 

47855  881 
the logical dependencies of locales and locale interpretation. See 
882 
commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  883 

47829  884 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
885 
declaration, and results are standardized before being stored. Thus 

886 
oldstyle "standard" after instantiation or composition of facts 

887 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

888 
indices of schematic variables. 

889 

890 
* Rule attributes in local theory declarations (e.g. locale or class) 

891 
are now statically evaluated: the resulting theorem is stored instead 

892 
of the original expression. INCOMPATIBILITY in rare situations, where 

893 
the historic accident of dynamic reevaluation in interpretations 

894 
etc. was exploited. 

895 

896 
* New tutorial "Programming and Proving in Isabelle/HOL" 

897

899 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

900 
Logic" as the recommended beginners tutorial, but does not cover all 

901 
of the material of that old tutorial. 

902

913 

47855  914 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
915 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

916 
expand it. This also works for objectlogic equality. (Formerly 

917 
undocumented feature.) 

918 

47856  919 
* Sort constraints are now propagated in simultaneous statements, just 
920 
like type constraints. INCOMPATIBILITY in rare situations, where 

921 
distinct sorts used to be assigned accidentally. For example: 

922 

923 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

924 

925 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

926 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

927 

928 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

929 
tolerant against multiple unifiers, as long as the final result is 

930 
unique. (As before, rules are composed in canonical righttoleft 

931 
order to accommodate newly introduced premises.) 

932 

47806  933 
* Renamed some inner syntax categories: 
934 

935 
num ~> num_token 

936 
xnum ~> xnum_token 

937 
xstr ~> str_token 

938 

939 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

940 
"num_position" etc. are mainly used instead (which also include 

941 
position information via constraints). 

942 

47829  943 
* Simplified configuration options for syntax ambiguity: see 
944 
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isarref 

945 
manual. Minor INCOMPATIBILITY. 

946 

47856  947 
* Discontinued configuration option "syntax_positions": atomic terms 
948 
in parse trees are always annotated by position constraints.

* Type 'a set is now a proper type constructor (just as before 
975 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

976 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  977 
sets separate, it is often sufficient to rephrase some set S that has 
978 
been accidentally used as predicates by "%x. x : S", and some 

979 
predicate P that has been accidentally used as set by "{x. P x}". 

980 
Corresponding proofs in a first step should be pruned from any 

981 
tinkering with former theorems mem_def and Collect_def as far as 

982 
possible. 

983 

984 
For developments which deliberately mix predicates and sets, a 

47464  985 
planning step is necessary to determine what should become a predicate 
986 
and what a set. It can be helpful to carry out that step in 

987 
Isabelle20111 before jumping right into the current release. 

988

47855  997 
positive and negated numeric literals, respectively. See also 
998 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some

47855  1018 
* Transfer: New package intended to generalize the existing 
1019 
"descending" method and related theorem attributes from the Quotient 

1020 
package. (Not all functionality is implemented yet, but future 

1021 
development will focus on Transfer as an eventual replacement for the 

1022 
corresponding parts of the Quotient package.) 

47809  1023 

1024 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1025 
which relate constants at two different types. Transfer rules may 

1026 
relate different type instances of the same polymorphic constant, 

1027 
or they may relate an operation on a raw type to a corresponding 

1028 
operation on an abstract type (quotient or subtype). For example: 

1029 

1030 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1031 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1032 

1033 
 transfer method: Replaces a subgoal on abstract types with an 

1034 
equivalent subgoal on the corresponding raw types. Constants are 

1035 
replaced with corresponding ones according to the transfer rules. 

1036 
Goals are generalized over all free variables by default; this is 

47851  1037 
necessary for variables whose types change, but can be overridden 
47855  1038 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1039 
variant transfer' method allows replacing a subgoal with one that 
1040 
is logically stronger (rather than equivalent). 

1041 

1042 
 relator_eq attribute: Collects identity laws for relators of 

1043 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1044 
transfer method uses these lemmas to infer transfer rules for 

1045 
nonpolymorphic constants on the fly. 

1046 

1047 
 transfer_prover method: Assists with proving a transfer rule for a 

1048 
new constant, provided the constant is defined in terms of other 

1049 
constants that already have transfer rules. It should be applied 

1050 
after unfolding the constant definitions. 

1051 

1052 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1053 
from type nat to type int. 

1054 

47851  1055 
* Lifting: New package intended to generalize the quotient_definition 
1056 
facility of the Quotient package; designed to work with Transfer. 

47809  1057 

1058 
 lift_definition command: Defines operations on an abstract type in 

1059 
terms of a corresponding operation on a representation 

1060 
type. Example syntax: 

1061 

1062 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1063 
is List.insert 

1064 

1065 
Users must discharge a respectfulness proof obligation when each 

1066 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1067 
the proof is discharged automatically.) The obligation is 

1068 
presented in a userfriendly, readable form; a respectfulness 

1069 
theorem in the standard format and a transfer rule are generated 

1070 
by the package. 

1071 

1072 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1073 
corresponding to a datatype invariant, such as dlist), 

1074 
lift_definition generates a code certificate theorem and sets up 

1075 
code generation for each constant. 

1076 

1077 
 setup_lifting command: Sets up the Lifting package to work with a 

1078 
userdefined type. The user must provide either a quotient theorem 

1079 
or a type_definition theorem. The package configures transfer 

1080 
rules for equality and quantifiers on the type, and sets up the 

1081 
lift_definition command to work with the type. 

1082 

1083 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1084 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1085 
Word/Word.thy and Library/Float.thy. 

47809  1086 

1087 
* Quotient package: 

1088 

1089 
 The 'quotient_type' command now supports a 'morphisms' option with 

1090 
rep and abs functions, similar to typedef. 

1091 

1092 
 'quotient_type' sets up new types to work with the Lifting and 

1093 
Transfer packages, as with 'setup_lifting'. 

1094 

1095 
 The 'quotient_definition' command now requires the user to prove a 

1096 
respectfulness property at the point where the constant is 

1097 
defined, similar to lift_definition; INCOMPATIBILITY. 

1098 

1099 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

1100 
accordingly, INCOMPATIBILITY. 

1101 

1102 
* New diagnostic command 'find_unused_assms' to find potentially 

1103 
superfluous assumptions in theorems using Quickcheck. 

1104 

1105 
* Quickcheck: 

1106 

1107 
 Quickcheck returns variable assignments as counterexamples, which 

1108 
allows to reveal the underspecification of functions under test. 

1109 
For example, refuting "hd xs = x", it presents the variable 

1110 
assignment xs = [] and x = a1 as a counterexample, assuming that 

1111 
any property is false whenever "hd []" occurs in it. 

1112 

1113 
These counterexample are marked as potentially spurious, as 

1114 
Quickcheck also returns "xs = []" as a counterexample to the 

1115 
obvious theorem "hd xs = hd xs". 

1116 

1117 
After finding a potentially spurious counterexample, Quickcheck 

1118 
continues searching for genuine ones. 

1119 

1120 
By default, Quickcheck shows potentially spurious and genuine 

1121 
counterexamples. The option "genuine_only" sets quickcheck to only 

1122 
show genuine counterexamples. 

1123 

1124 
 The command 'quickcheck_generator' creates random and exhaustive 

1125 
value generators for a given type and operations. 

1126 

1127 
It generates values by using the operations as if they were 

1128 
constructors of that type. 

1129 

1130 
 Support for multisets. 

1131 

1132 
 Added "use_subtype" options. 

1133 

1134 
 Added "quickcheck_locale" configuration to specify how to process 

1135 
conjectures in a locale context. 

1136 

47855  1137 
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option 
1138 
and affecting 'rat' and 'real'. 

47809  1139 

1140 
* Sledgehammer: 

1141 
 Integrated more tightly with SPASS, as described in the ITP 2012 

1142 
paper "More SPASS with Isabelle". 

1143 
 Made it try "smt" as a fallback if "metis" fails or times out. 

1144 
 Added support for the following provers: AltErgo (via Why3 and 

1145 
TFF1), iProver, iProverEq. 

1146 
 Sped up the minimizer. 

1147 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

1148 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

1149 
 Renamed "sound" option to "strict". 

1150 

47855  1151 
* Metis: Added possibility to specify lambda translations scheme as a 
1152 
parenthesized argument (e.g., "by (metis (lifting) ...)"). 

1153 

1154 
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates". 

1155 

1156 
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY. 

47809  1157 

47856  1158 
* New "case_product" attribute to generate a case rule doing multiple 
1159 
case distinctions at the same time. E.g. 

1160 

1161 
list.exhaust [case_product nat.exhaust] 

1162 

1163 
produces a rule which can be used to perform case distinction on both 

1164 
a list and a nat. 

1165 

47809  1166 
* New "eventually_elim" method as a generalized variant of the 
47855  1167 
eventually_elim* rules. Supports structured proofs.

1174 

1175

1176 

1177 
* Datatype: type parameters allow explicit sort constraints. 

1178 

47855  1179 
* Concrete syntax for case expressions includes constraints for source 
1180 
positions, and thus produces Prover IDE markup for its bindings. 

1181 
INCOMPATIBILITY for oldstyle syntax translations that augment the

unfolding "foldr_conv_fold" and "foldl_conv_fold". 

1339 

1340 
* Dropped lemmas minus_set_foldr, union_set_foldr, union_coset_foldr, 

1341 
inter_coset_foldr, Inf_fin_set_foldr, Sup_fin_set_foldr, 

1342 
Min_fin_set_foldr, Max_fin_set_foldr, Inf_set_foldr, Sup_set_foldr, 

1343 
INF_set_foldr, SUP_set_foldr. INCOMPATIBILITY. Prefer corresponding 

1344 
lemmas over fold rather than foldr, or make use of lemmas 

1345 
fold_conv_foldr and fold_rev. 

1346 

1347 
* Congruence rules Option.map_cong and Option.bind_cong for recursion 

1348 
through option types.

* "Transitive_Closure.ntrancl": bounded transitive closure on 
1351 
relations. 

1352 

1353 
* Constant "Set.not_member" now qualified. INCOMPATIBILITY. 

1354 

1355 
* Theory Int: Discontinued many legacy theorems specific to type int. 

1356 
INCOMPATIBILITY, use the corresponding generic theorems instead.

47703  1400 
are expressed via type classes again. The special syntax 
1401 
\<oplus>/\<otimes> has been replaced by plain +/*. Removed constant 

1402 
setsum_set, which is now subsumed by Big_Operators.setsum. 

1403 
INCOMPATIBILITY.

trees is now inside a type class context. Names of affected 

1410 
operations and lemmas have been prefixed by rbt_. INCOMPATIBILITY for 

1411 
theories working directly with raw redblack trees, adapt the names as

1415 
bulkload > rbt_bulkload
