* Renamed command 'print_configs' to 'print_options'. Minor 
30 
INCOMPATIBILITY. 

31 

51417  32 
* Sessions may be organized via 'chapter' specifications in the ROOT 
33 
file, which determines a twolevel hierarchy of browser info. The old 

34 
treelike organization via implicit subsession relation, with its 

35 
tendency towards erratic fluctuation of URLs, has been discontinued.

44 
'ML_file' in Isabelle2013. Minor INCOMPATIBILITY. 

45 

52415  46 
* Updated and extended "isarref" and "implementation" manual, 
47 
eliminated old "ref" manual. 

48 

52430  49 
* Proper diagnostic command 'print_state'. Old 'pr' (with its 
50 
implicit change of some global references) is retained for now as 

51 
control command, e.g. for ProofGeneral 3.7.x. 

52 

52549  53 
* Discontinued 'print_drafts' command with its oldfashioned PS output 
54 
and Unix commandline print spooling. Minor INCOMPATIBILITY: use 

55 
'display_drafts' instead and print via the regular document viewer.

*** Prover IDE  Isabelle/Scala/jEdit *** 
59 

52818  60 
* Improved "Theories" panel: Continuous checking of proof document 
61 
(visible and required parts) may be controlled explicitly, using check 

62 
box or shortcut "C+e ENTER". Individual theory nodes may be marked 

63 
explicitly as required and checked in full, using check box or 

64 
shortcut "C+e SPACE". 

52779  65 

52646  66 
* Strictly monotonic document update, without premature cancelation of 
67 
running transactions that are still needed: avoid reset/restart of 

68 
such command executions while editing. 

69 

70 
* Support for asynchronous print functions, as overlay to existing 

71 
document content. 

72 

73 
* Support for automatic tools in HOL, which try to prove or disprove 

74 
toplevel theorem statements. 

75 

52949  76 
* Dockable window "Find" provides query operations for formal entities 
77 
(GUI frontend to 'find_theorems' command). 

78 

52445  79 
* Dockable window "Documentation" provides access to Isabelle 
80 
documentation. 

81 

53050  82 
* Dockable window "Sledgehammer" manages asynchronous / parallel 
83 
sledgehammer runs over existing document sources, independently of 

84 
normal editing and checking process. 

85 

51533  86 
* Dockable window "Timing" provides an overview of relevant command 
87 
timing information. 

88 

53161  89 
* Action isabelle.resetfontsize resets main text area font size 
90 
according to Isabelle/Scala plugin option "jedit_font_reset_size" 

91 
(cf. keyboard shortcut C+0).

98 

99 
 Various Isabelle plugin options to control popup behaviour and 

100 
immediate insertion into buffer. 

101 

102 
 Lightweight popup, which avoids explicit window (more reactive

105 
the jEdit text area. 
53326  106 

107 
 Explicit completion via standard jEdit shortcut C+b, which has 

108 
been remapped to action "isabelle.complete" (fallback on regular 

109 
"completeword" for nonIsabelle buffers). 

110 

111 
 Implicit completion via keyboard input on text area, with popup or 

112 
immediate insertion into buffer. 

113 

114 
 Implicit completion of plain words requires at least 3 characters 

115 
(was 2 before). 

116 

117 
 Immediate completion ignores plain words; it requires > 1 

118 
characters of symbol abbreviation to complete, otherwise fallback 

119 
on completion popup. 

120 

121 
 Isabelle Symbols are only completed in backslashed forms, 

122 
e.g. \forall or \<forall> that both produce the Isabelle symbol 

123 
\<forall> in its Unicode rendering. 

124 

125 
 Refined table of Isabelle symbol abbreviations (see 

126 
$ISABELLE_HOME/etc/symbols).

52788  131 
* Type theory is now immutable, without any special treatment of 
132 
drafts or linear updates (which could lead to "stale theory" errors in 

133 
the past). Discontinued obsolete operations like Theory.copy, 

134 
Theory.checkpoint, and the auxiliary type theory_ref. Minor 

135 
INCOMPATIBILITY.

144 
now the default. Minor INCOMPATIBILITY. 

145 

51747  146 
* Targetsensitive commands 'interpretation' and 'sublocale'. 
147 
Particulary, 'interpretation' now allows for nonpersistent 

53160  148 
interpretation within "context ... begin ... end" blocks. See 
149 
"isarref" manual for details. 

51747  150

169 

53160  170

* HOL/BNF: 
183 
 Various improvements to BNFbased (co)datatype package, including a

"primrec_new" command, a "datatype_new_compat" command, and 
53307  185 
documentation. See "datatypes.pdf" for details.

 Renamed keywords: 

187

198 
 Explicit conversions from and to lists of coefficients, used for 

199 
generated code. 

200 
 Replaced recursion operator poly_rec by fold_coeffs. 

201 
 Prefer preexisting gcd operation for gcd. 

202 
 Fact renames: 

52380  203

* Reification and reflection: 
53160  209 
 Reification is now directly available in HOLMain in structure 
210 
"Reification". 

211 
 Reflection now handles multiple lists with variables also. 

212 
 The whole reflection stack has been decomposed into conversions.

53160  218 
* Nested case expressions are now translated in a separate check phase 
219 
rather than during parsing. The data for case combinators is separated 

220 
from the datatype package. The declaration attribute 

221 
"case_translation" can be used to register new case combinators: 

51682  222 

223 
declare [[case_translation case_combinator constructor1 ... constructorN]] 

224 

51596  225 
* Notation "{p:A. P}" now allows tuple patterns as well. 
226 

51489  227 
* Revised devices for recursive definitions over finite sets: 
228 
 Only one fundamental fold combinator on finite set remains: 

229 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

230 
This is now identity on infinite sets.

 Locales ("mini packages") for fundamental definitions with 
51489  232 
Finite_Set.fold: folding, folding_idem. 
233 
 Locales comm_monoid_set, semilattice_order_set and 

234 
semilattice_neutr_order_set for big operators on sets. 

235 
See theory Big_Operators for canonical examples. 

236 
Note that foundational constants comm_monoid_set.F and 

237 
semilattice_set.F correspond to former combinators fold_image 

238 
and fold1 respectively. These are now gone. You may use 

51490  239 
those foundational constants as substitutes, but it is 
51489  240 
preferable to interpret the above locales accordingly. 
241 
 Dropped class ab_semigroup_idem_mult (special case of lattice, 

242 
no longer needed in connection with Finite_Set.fold etc.)

254 

53160  255 
* Numeric types mapped by default to target language numerals: natural 
256 
(replaces former code_numeral) and integer (replaces former code_int). 

257 
Conversions are available as integer_of_natural / natural_of_integer / 

258 
integer_of_nat / nat_of_integer (in HOL) and 

259 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in 

260 
ML). INCOMPATIBILITY.

273 
complete lattice but does not assume the existence of the top and 

274 
bottom elements. Allows to generalize some lemmas about reals and 

275 
extended reals. Removed SupInf and replaced it by the instantiation 

276 
of conditionally_complete_lattice for real. Renamed lemmas about 

277 
conditionallycomplete lattice from Sup_... to cSup_... and from 

278 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

279 
lemmas.

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

320 
i.e. to represent derivatives from left or right.

323 

324 
F within X = inf F (principal X)

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

327 
abbreviation for "at x within UNIV" 

328

 Introduce named theorem collections tendsto_intros, continuous_intros, 

330 
continuous_on_intros and FDERIV_intros. Theorems in tendsto_intros (or 

331 
FDERIV_intros) are also available as tendsto_eq_intros (or 

332 
FDERIV_eq_intros) where the righthand side is replaced by a congruence

*** Prover IDE  Isabelle/Scala/jEdit *** 
489 

490 
* Parallel terminal proofs ('by') are enabled by default, likewise 

491 
proofs that are built into packages like 'datatype', 'function'. This 

492 
allows to "run ahead" checking the theory specifications on the 

493 
surface, while the prover is still crunching on internal 

494 
justifications. Unfinished / cancelled proofs are restarted as 

495 
required to complete full proof checking eventually. 

496 

497 
* Improved output panel with tooltips, hyperlinks etc. based on the 

498 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

499 
tooltips leads to some window that supports the same recursively, 

500 
which can lead to stacks of tooltips as the semantic document content 

501 
is explored. ESCAPE closes the whole stack, individual windows may be 

502 
closed separately, or detached to become independent jEdit dockables. 

503 

50717  504 
* Improved support for commands that produce graph output: the text 
505 
message contains a clickable area to open a new instance of the graph 

506 
browser on demand. 

507 

49968  508 
* More robust incremental parsing of outer syntax (partial comments, 
509 
malformed symbols). Changing the balance of open/close quotes and 

510 
comment delimiters works more conveniently with unfinished situations 

511 
that frequently occur in user interaction. 

512 

513 
* More efficient painting and improved reactivity when editing large 

514

order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped 

689 
old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead. 

690 
Renamed lemmas accordingly.

692 
 Added constant "list_hembeq" for homeomorphic embedding on 

693 
lists. Added abbreviation "sublisteq" for special case 

694

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

747 
functions (supersedes the AFP entry "Code Generation for Functions as 

748 
Data"). 

749 

750 
* Theory Library/Phantom: generic phantom type to make a type 

751 
parameter appear in a constant's type. This alternative to adding 

752 
TYPE('a) as another parameter avoids unnecessary closures in generated 

753 
code. 

754 

755 
* Theory Library/RBT_Impl: efficient construction of redblack trees 

756 
from sorted associative lists. Merging two trees with rbt_union may 

757 
return a structurally different tree than before. Potential

* Bundled declarations associate attributed fact expressions with a 
962 
given name in the context. These may be later included in other 

963 
contexts. This allows to manage context extensions casually, without 

47855  964 
the logical dependencies of locales and locale interpretation. See 
965 
commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  966 

47829  967 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
968 
declaration, and results are standardized before being stored. Thus 

969 
oldstyle "standard" after instantiation or composition of facts 

970 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

971 
indices of schematic variables. 

972 

973 
* Rule attributes in local theory declarations (e.g. locale or class) 

974 
are now statically evaluated: the resulting theorem is stored instead 

975 
of the original expression. INCOMPATIBILITY in rare situations, where 

976 
the historic accident of dynamic reevaluation in interpretations 

977 
etc. was exploited. 

978 

979 
* New tutorial "Programming and Proving in Isabelle/HOL" 

980

982 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

983 
Logic" as the recommended beginners tutorial, but does not cover all 

984 
of the material of that old tutorial. 

985

996 

47855  997 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
998 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

999 
expand it. This also works for objectlogic equality. (Formerly 

1000 
undocumented feature.) 

1001 

47856  1002 
* Sort constraints are now propagated in simultaneous statements, just 
1003 
like type constraints. INCOMPATIBILITY in rare situations, where 

1004 
distinct sorts used to be assigned accidentally. For example: 

1005 

1006 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

1007 

1008 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

1009 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

1010 

1011 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

1012 
tolerant against multiple unifiers, as long as the final result is 

1013 
unique. (As before, rules are composed in canonical righttoleft 

1014 
order to accommodate newly introduced premises.) 

1015 

47806  1016 
* Renamed some inner syntax categories: 
1017 

1018 
num ~> num_token 

1019 
xnum ~> xnum_token 

1020 
xstr ~> str_token 

1021 

1022 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

1023 
"num_position" etc. are mainly used instead (which also include 

1024 
position information via constraints). 

1025 

47829  1026 
* Simplified configuration options for syntax ambiguity: see

* Type 'a set is now a proper type constructor (just as before 
1058 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

1059 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  1060 
sets separate, it is often sufficient to rephrase some set S that has 
1061 
been accidentally used as predicates by "%x. x : S", and some 

1062 
predicate P that has been accidentally used as set by "{x. P x}". 

1063 
Corresponding proofs in a first step should be pruned from any 

1064 
tinkering with former theorems mem_def and Collect_def as far as 

1065 
possible. 

1066 

1067 
For developments which deliberately mix predicates and sets, a 

47464  1068 
planning step is necessary to determine what should become a predicate 
1069 
and what a set. It can be helpful to carry out that step in 

1070 
Isabelle20111 before jumping right into the current release. 

1071 

47855  1072 
* Code generation by default implements sets as container type rather 
1073 
than predicates. INCOMPATIBILITY. 

1074 

1075 
* New type synonym 'a rel = ('a * 'a) set 

1076 

47464  1077 
* The representation of numerals has changed. Datatype "num" 
1078 
represents strictly positive binary numerals, along with functions 

1079 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

47855  1080 
positive and negated numeric literals, respectively. See also 
1081 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some 

1082

47855  1101 
* Transfer: New package intended to generalize the existing 
1102 
"descending" method and related theorem attributes from the Quotient 

1103 
package. (Not all functionality is implemented yet, but future 

1104 
development will focus on Transfer as an eventual replacement for the 

1105 
corresponding parts of the Quotient package.) 

47809  1106 

1107 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1108 
which relate constants at two different types. Transfer rules may 

1109 
relate different type instances of the same polymorphic constant, 

1110 
or they may relate an operation on a raw type to a corresponding 

1111 
operation on an abstract type (quotient or subtype). For example: 

1112 

1113 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1114 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1115 

1116 
 transfer method: Replaces a subgoal on abstract types with an 

1117 
equivalent subgoal on the corresponding raw types. Constants are 

1118 
replaced with corresponding ones according to the transfer rules. 

1119 
Goals are generalized over all free variables by default; this is 

47851  1120 
necessary for variables whose types change, but can be overridden 
47855  1121 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1122 
variant transfer' method allows replacing a subgoal with one that 
1123 
is logically stronger (rather than equivalent). 

1124 

1125 
 relator_eq attribute: Collects identity laws for relators of 

1126 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1127 
transfer method uses these lemmas to infer transfer rules for 

1128 
nonpolymorphic constants on the fly. 

1129 

1130 
 transfer_prover method: Assists with proving a transfer rule for a 

1131 
new constant, provided the constant is defined in terms of other 

1132 
constants that already have transfer rules. It should be applied 

1133 
after unfolding the constant definitions. 

1134 

1135 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1136 
from type nat to type int. 

1137 

47851  1138 
* Lifting: New package intended to generalize the quotient_definition 
1139 
facility of the Quotient package; designed to work with Transfer. 

47809  1140 

1141 
 lift_definition command: Defines operations on an abstract type in 

1142 
terms of a corresponding operation on a representation 

1143 
type. Example syntax: 

1144 

1145 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1146 
is List.insert 

1147 

1148 
Users must discharge a respectfulness proof obligation when each 

1149 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1150 
the proof is discharged automatically.) The obligation is 

1151 
presented in a userfriendly, readable form; a respectfulness 

1152 
theorem in the standard format and a transfer rule are generated 

1153 
by the package. 

1154 

1155 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1156 
corresponding to a datatype invariant, such as dlist), 

1157 
lift_definition generates a code certificate theorem and sets up 

1158 
code generation for each constant. 

1159 

1160 
 setup_lifting command: Sets up the Lifting package to work with a 

1161 
userdefined type. The user must provide either a quotient theorem 

1162 
or a type_definition theorem. The package configures transfer 

1163 
rules for equality and quantifiers on the type, and sets up the 

1164 
lift_definition command to work with the type. 

1165 

1166 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1167 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1168 
Word/Word.thy and Library/Float.thy. 

47809  1169 

1170 
* Quotient package: 

1171 

1172 
 The 'quotient_type' command now supports a 'morphisms' option with 

1173 
rep and abs functions, similar to typedef. 

1174 

1175 
 'quotient_type' sets up new types to work with the Lifting and 

1176 
Transfer packages, as with 'setup_lifting'. 

1177 

1178 
 The 'quotient_definition' command now requires the user to prove a 

1179 
respectfulness property at the point where the constant is 

1180 
defined, similar to lift_definition; INCOMPATIBILITY. 

1181 

1182 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

1183 
accordingly, INCOMPATIBILITY. 

1184 

1185 
* New diagnostic command 'find_unused_assms' to find potentially 

1186 
superfluous assumptions in theorems using Quickcheck. 

1187 

1188 
* Quickcheck: 

1189 

1190 
 Quickcheck returns variable assignments as counterexamples, which 

1191 
allows to reveal the underspecification of functions under test. 

1192 
For example, refuting "hd xs = x", it presents the variable 

1193 
assignment xs = [] and x = a1 as a counterexample, assuming that 

1194 
any property is false whenever "hd []" occurs in it. 

1195 

1196 
These counterexample are marked as potentially spurious, as 

1197 
Quickcheck also returns "xs = []" as a counterexample to the 

1198 
obvious theorem "hd xs = hd xs". 

1199 

1200 
After finding a potentially spurious counterexample, Quickcheck 

1201 
continues searching for genuine ones. 

1202 

1203 
By default, Quickcheck shows potentially spurious and genuine 

1204 
counterexamples. The option "genuine_only" sets quickcheck to only 

1205 
show genuine counterexamples. 

1206 

1207 
 The command 'quickcheck_generator' creates random and exhaustive 

1208 
value generators for a given type and operations. 

1209 

1210 
It generates values by using the operations as if they were 

1211 
constructors of that type. 

1212 

1213 
 Support for multisets. 

1214 

1215 
 Added "use_subtype" options. 

1216 

1217 
 Added "quickcheck_locale" configuration to specify how to process 

1218 
conjectures in a locale context. 

1219 

47855  1220 
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option 
1221 
and affecting 'rat' and 'real'. 

47809  1222 

1223 
* Sledgehammer: 

1224 
 Integrated more tightly with SPASS, as described in the ITP 2012 

1225 
paper "More SPASS with Isabelle". 

1226 
 Made it try "smt" as a fallback if "metis" fails or times out. 

1227 
 Added support for the following provers: AltErgo (via Why3 and 

1228 
TFF1), iProver, iProverEq. 

1229 
 Sped up the minimizer. 

1230 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

1231 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

1232 
 Renamed "sound" option to "strict". 

1233 

47855  1234 
* Metis: Added possibility to specify lambda translations scheme as a 
1235 
parenthesized argument (e.g., "by (metis (lifting) ...)"). 

1236 

1237 
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates". 

1238 

1239 
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY. 

47809  1240 

47856  1241 
* New "case_product" attribute to generate a case rule doing multiple 
1242 
case distinctions at the same time. E.g. 

1243 

1244 
list.exhaust [case_product nat.exhaust] 

1245 

1246 
produces a rule which can be used to perform case distinction on both 

1247 
a list and a nat. 

1248 

47809  1249 
* New "eventually_elim" method as a generalized variant of the 
47855  1250 
eventually_elim* rules. Supports structured proofs.

47855  1262

INCOMPATIBILITY. For the common phrases "%xs. List.foldr plus xs 0" 

1419 
and "List.foldl plus 0", prefer "List.listsum". Otherwise it can be 

1420 
useful to boil down "List.foldr" and "List.foldl" to "List.fold" by 

1421 
unfolding "foldr_conv_fold" and "foldl_conv_fold".

INF_set_foldr, SUP_set_foldr. INCOMPATIBILITY. Prefer corresponding 

1427 
lemmas over fold rather than foldr, or make use of lemmas 

1428 
fold_conv_foldr and fold_rev.
