53971  9 
* Discontinued obsolete 'uses' within theory header. Note that 
10 
commands like 'ML_file' work without separate declaration of file 

11 
dependencies. Minor INCOMPATIBILITY. 

12 

13 
* Discontinued redundant 'use' command, which was superseded by 

14 
'ML_file' in Isabelle2013. Minor INCOMPATIBILITY.

quick_and_dirty, instead of historical poking into mutable reference. 
52059  35 

52060  36 
* Renamed command 'print_configs' to 'print_options'. Minor 
37 
INCOMPATIBILITY. 

38 

52430  39 
* Proper diagnostic command 'print_state'. Old 'pr' (with its 
40 
implicit change of some global references) is retained for now as 

41 
control command, e.g. for ProofGeneral 3.7.x. 

42 

52549  43 
* Discontinued 'print_drafts' command with its oldfashioned PS output 
44 
and Unix commandline print spooling. Minor INCOMPATIBILITY: use 

45 
'display_drafts' instead and print via the regular document viewer. 

46 

53971  47 
* Updated and extended "isarref" and "implementation" manual, 
48 
eliminated old "ref" manual.

*** Prover IDE  Isabelle/Scala/jEdit *** 
52 

53971  53 
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or 
53852  54 
Documentation panel. 
55 

53971  56 
* Dockable window "Documentation" provides access to Isabelle 
57 
documentation. 

52646  58 

52949  59 
* Dockable window "Find" provides query operations for formal entities 
60 
(GUI frontend to 'find_theorems' command). 

61 

53050  62 
* Dockable window "Sledgehammer" manages asynchronous / parallel 
63 
sledgehammer runs over existing document sources, independently of 

64 
normal editing and checking process. 

65 

51533  66 
* Dockable window "Timing" provides an overview of relevant command 
67 
timing information. 

68 

53971  69 
* Improved dockable window "Theories": Continuous checking of proof 
70 
document (visible and required parts) may be controlled explicitly, 

71 
using check box or shortcut "C+e ENTER". Individual theory nodes may 

72 
be marked explicitly as required and checked in full, using check box 

73 
or shortcut "C+e SPACE". 

74 

75 
* Strictly monotonic document update, without premature cancellation of 

76 
running transactions that are still needed: avoid reset/restart of 

77 
such command executions while editing. 

53271
0460d6962ced

78 

53326  79 
* Improved completion mechanism, which is now managed by the 
53981  80 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 
81 
symbol abbreviations (see $ISABELLE_HOME/etc/symbols). 

53326  82 

53971  83 
* Support for asynchronous print functions, as overlay to existing 
84 
document content. 

85 

86 
* Support for automatic tools in HOL, which try to prove or disprove 

87 
toplevel theorem statements. 

88 

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). 

92 

93 
* File specifications in jEdit (e.g. file browser) may refer to 

94 
$ISABELLE_HOME on all platforms. Discontinued obsolete 

95 
$ISABELLE_HOME_WINDOWS variable. 

96 

97 
* Improved support for Linux lookandfeel "GTK+", see also "Utilities 

98 
/ Global Options / Appearance". 

99 

100 
* Improved support of native Mac OS X functionality via "MacOSX" 

101 
plugin, which is now enabled by default.

*** Pure *** 
105 

51747  106 
* Targetsensitive commands 'interpretation' and 'sublocale'. 
53971  107 
Particularly, 'interpretation' now allows for nonpersistent 
53160  108 
interpretation within "context ... begin ... end" blocks. See 
109 
"isarref" manual for details. 

51747  110 

51565  111 
* Improved locales diagnostic command 'print_dependencies'. 
112 

51313  113 
* Discontinued obsolete 'axioms' command, which has been marked as 
114 
legacy since Isabelle20092. INCOMPATIBILITY, use 'axiomatization' 

115 
instead, while observing its uniform scope for polymorphism.

53971  120 
* System option "proofs" has been discontinued. Instead the global 
121 
state of Proofterm.proofs is persistently compiled into logic images 

122 
as required, notably HOLProofs. Users no longer need to change 

123 
Proofterm.proofs dynamically. Minor INCOMPATIBILITY. 

124 

125 
* Syntax translation functions (print_translation etc.) always depend 

126 
on Proof.context. Discontinued former "(advanced)" option  this is 

127 
now the default. Minor INCOMPATIBILITY. 

128 

129 
* Former global reference trace_unify_fail is now available as 

130 
configuration option "unify_trace_failure" (global context only). 

131 

52463  132 
* SELECT_GOAL now retains the syntactic context of the overall goal 
133 
state (schematic variables etc.). Potential INCOMPATIBILITY in rare 

134 
situations.

isarref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy). 
141 

53160  142

143 
equations uniformly. Use explicit 'code equation' and 'code abstract' 

144 
to distinguish both when desired.

54010  157 
commands "primrec_new", "primcorec", and "datatype_new_compat", 
53766  158 
as well as documentation. See "datatypes.pdf" for details.

* Lifting: 
173 
 parametrized correspondence relations are now supported: 

174 
+ parametricity theorems for the raw term can be specified in 

175 
the command lift_definition, which allow us to generate stronger 

176 
transfer rules 

177 
+ setup_lifting generates stronger transfer rules if parametric 

178 
correspondence relation can be generated 

179 
+ various new properties of the relator must be specified to support 

180 
parametricity 

181 
+ parametricity theorem for the Quotient relation can be specified 

182 
 setup_lifting generates domain rules for the Transfer package 

183 
 stronger reflexivity prover of respectfulness theorems for type 

184 
copies 

185 
 ===> and > are now local. The symbols can be introduced 

186 
by interpreting the locale lifting_syntax (typically in an 

187 
anonymous context) 

188 
 Lifting/Transfer relevant parts of Library/Quotient_* are now in 

189 
Main. Potential INCOMPATIBILITY 

190 
 new commands for restoring and deleting Lifting/Transfer context: 

191 
lifting_forget, lifting_update 

192 
 the command print_quotmaps was renamed to print_quot_maps. 

193 
INCOMPATIBILITY 

194 

195 
* Transfer: 

196 
 better support for domains in Transfer: replace Domainp T 

197 
by the actual invariant in a transferred goal 

198 
 transfer rules can have as assumptions other transfer rules 

199 
 Experimental support for transferring from the raw level to the 

200 
abstract level: Transfer.transferred attribute 

201 
 Attribute version of the transfer method: untransferred attribute 

202 

203 

53613  204 
* Function package: For mutually recursive functions f and g, separate 
205 
cases rules f.cases and g.cases are generated instead of unusable 

206 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

207 
in the case that the unusable rule was used nevertheless. 

208 

209 
* Function package: For each function f, new rules f.elims are 

210 
automatically generated, which eliminate equalities of the form "f x = 

211 
t". 

212 

53983  213 
* New command 'fun_cases' derives adhoc elimination rules for 
53613  214 
function equations as simplified instances of f.elims, analogous to 
53983  215 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples. 
53613  216 

52380  217 
* Library/Polynomial.thy: 
53160  218 
 Use lifting for primitive definitions. 
219 
 Explicit conversions from and to lists of coefficients, used for 

220 
generated code. 

221 
 Replaced recursion operator poly_rec by fold_coeffs. 

222 
 Prefer preexisting gcd operation for gcd. 

223 
 Fact renames: 

52380  224 
poly_eq_iff ~> poly_eq_poly_eq_iff 
225 
poly_ext ~> poly_eqI 

226 
expand_poly_eq ~> poly_eq_iff 

53307  227 
IMCOMPATIBILITY. 
52380  228 

54021  229 
* New Library/FSet.thy: type of finite sets defined as a subtype of 
230 
sets defined by Lifting/Transfer 

231 

52286  232 
* Reification and reflection: 
53160  233 
 Reification is now directly available in HOLMain in structure 
234 
"Reification". 

235 
 Reflection now handles multiple lists with variables also. 

236 
 The whole reflection stack has been decomposed into conversions. 

52286  237 
INCOMPATIBILITY. 
238 

53983  239 
* Stronger precedence of syntax for big intersection and union on 
240 
sets, in accordance with corresponding lattice operations.

242 

53160  243 
* Nested case expressions are now translated in a separate check phase 
244 
rather than during parsing. The data for case combinators is separated 

245 
from the datatype package. The declaration attribute 

246 
"case_translation" can be used to register new case combinators: 

51682  247 

248 
declare [[case_translation case_combinator constructor1 ... constructorN]] 

249 

53681  250 
* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and 
251 
case_of_simps to convert function definitions between a list of 

252 
equations with patterns on the lhs and a single equation with case 

253 
expressions on the rhs. See also Ex/Simps_Case_Conv_Examples.thy. 

254 

51596  255 
* Notation "{p:A. P}" now allows tuple patterns as well. 
256 

51489  257 
* Revised devices for recursive definitions over finite sets: 
258 
 Only one fundamental fold combinator on finite set remains: 

259 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

260 
This is now identity on infinite sets.

 Locales ("mini packages") for fundamental definitions with 
51489  262 
Finite_Set.fold: folding, folding_idem. 
263 
 Locales comm_monoid_set, semilattice_order_set and 

264 
semilattice_neutr_order_set for big operators on sets. 

265 
See theory Big_Operators for canonical examples. 

266 
Note that foundational constants comm_monoid_set.F and 

267 
semilattice_set.F correspond to former combinators fold_image 

268 
and fold1 respectively. These are now gone. You may use 

51490  269 
those foundational constants as substitutes, but it is 
53983  270 
preferable to interpret the above locales accordingly. 
51489  271 
 Dropped class ab_semigroup_idem_mult (special case of lattice, 
272 
no longer needed in connection with Finite_Set.fold etc.)

* Numeric types mapped by default to target language numerals: natural 
283 
(replaces former code_numeral) and integer (replaces former code_int). 

284 
Conversions are available as integer_of_natural / natural_of_integer / 

285 
integer_of_nat / nat_of_integer (in HOL) and 

286 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in

295 
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the

* Introduce type class "conditionally_complete_lattice": Like a 
300 
complete lattice but does not assume the existence of the top and 

301 
bottom elements. Allows to generalize some lemmas about reals and 

302 
extended reals. Removed SupInf and replaced it by the instantiation 

303 
of conditionally_complete_lattice for real. Renamed lemmas about 

304 
conditionallycomplete lattice from Sup_... to cSup_... and from 

305 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

306 
lemmas.

 continuous and continuos_on from Multivariate_Analysis: 

53983  329 
"continuous" is the continuity of a function at a filter. "isCont" 
330 
is now an abbrevitation: "isCont x f == continuous (at _) f". 

331 

332 
Generalized continuity lemmas from isCont to continuous on an 

333 
arbitrary filter. 

334 

335 
 compact from Multivariate_Analysis. Use Bolzano's lemma to prove 

336 
compactness of closed intervals on reals. Continuous functions 

337 
attain infimum and supremum on compact sets. The inverse of a 

338 
continuous function is continuous, when the function is continuous 

339 
on a compact set.

definition of DERIV on FDERIV. Add variants of DERIV and FDERIV 

352 
which are restricted to sets, i.e. to represent derivatives from 

353 
left or right. 

51732  354 

355 
 Removed the withinfilter. It is replaced by the principal filter: 

356 

357 
F within X = inf F (principal X)

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

360 
abbreviation for "at x within UNIV" 

361 

53983  362 
 Introduce named theorem collections tendsto_intros, 
363 
continuous_intros, continuous_on_intros and FDERIV_intros. Theorems 

364 
in tendsto_intros (or FDERIV_intros) are also available as 

365 
tendsto_eq_intros (or FDERIV_eq_intros) where the righthand side 

366 
is replaced by a congruence rule. This allows to apply them as 

367 
intro rules and then proving equivalence by the simplifier.

*** Prover IDE  Isabelle/Scala/jEdit *** 
549 

550 
* Parallel terminal proofs ('by') are enabled by default, likewise 

551 
proofs that are built into packages like 'datatype', 'function'. This 

552 
allows to "run ahead" checking the theory specifications on the 

553 
surface, while the prover is still crunching on internal 

554 
justifications. Unfinished / cancelled proofs are restarted as 

555 
required to complete full proof checking eventually. 

556 

557 
* Improved output panel with tooltips, hyperlinks etc. based on the 

558 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

559 
tooltips leads to some window that supports the same recursively, 

560 
which can lead to stacks of tooltips as the semantic document content 

561 
is explored. ESCAPE closes the whole stack, individual windows may be 

562 
closed separately, or detached to become independent jEdit dockables. 

563 

50717  564 
* Improved support for commands that produce graph output: the text 
565 
message contains a clickable area to open a new instance of the graph 

566 
browser on demand. 

567 

49968  568 
* More robust incremental parsing of outer syntax (partial comments, 
569 
malformed symbols). Changing the balance of open/close quotes and 

570 
comment delimiters works more conveniently with unfinished situations 

571 
that frequently occur in user interaction. 

572 

573 
* More efficient painting and improved reactivity when editing large 

574

 Added constant "list_hembeq" for homeomorphic embedding on

807 
functions (supersedes the AFP entry "Code Generation for Functions as

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

811 
parameter appear in a constant's type. This alternative to adding 

812 
TYPE('a) as another parameter avoids unnecessary closures in generated 

813 
code.

* Bundled declarations associate attributed fact expressions with a 
1022 
given name in the context. These may be later included in other 

1023 
contexts. This allows to manage context extensions casually, without 

47855  1024 
the logical dependencies of locales and locale interpretation. See 
1025 
commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  1026 

47829  1027 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
1028 
declaration, and results are standardized before being stored. Thus 

1029 
oldstyle "standard" after instantiation or composition of facts 

1030 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

1031 
indices of schematic variables. 

1032 

1033 
* Rule attributes in local theory declarations (e.g. locale or class) 

1034 
are now statically evaluated: the resulting theorem is stored instead 

1035 
of the original expression. INCOMPATIBILITY in rare situations, where 

1036 
the historic accident of dynamic reevaluation in interpretations 

1037 
etc. was exploited. 

1038 

1039 
* New tutorial "Programming and Proving in Isabelle/HOL" 

1040 
("progprove"). It completely supersedes "A Tutorial Introduction to 

1041 
Structured Isar Proofs" ("isaroverview"), which has been removed. It 

1042 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

1043 
Logic" as the recommended beginners tutorial, but does not cover all 

1044 
of the material of that old tutorial. 

1045 

1046 
* Updated and extended reference manuals: "isarref",

47855  1057 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
1058 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

1059 
expand it. This also works for objectlogic equality. (Formerly 

1060 
undocumented feature.) 

1061 

47856  1062 
* Sort constraints are now propagated in simultaneous statements, just 
1063 
like type constraints. INCOMPATIBILITY in rare situations, where 

1064 
distinct sorts used to be assigned accidentally. For example: 

1065 

1066 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

1067 

1068 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

1069 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

1070 

1071 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

1072 
tolerant against multiple unifiers, as long as the final result is 

1073 
unique. (As before, rules are composed in canonical righttoleft 

1074 
order to accommodate newly introduced premises.) 

1075 

47806  1076 
* Renamed some inner syntax categories: 
1077 

1078 
num ~> num_token 

1079 
xnum ~> xnum_token 

1080 
xstr ~> str_token 

1081 

1082 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

1083 
"num_position" etc. are mainly used instead (which also include 

1084 
position information via constraints). 

1085 

47829  1086 
* Simplified configuration options for syntax ambiguity: see

* Type 'a set is now a proper type constructor (just as before 
1118 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

1119 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  1120 
sets separate, it is often sufficient to rephrase some set S that has 
1121 
been accidentally used as predicates by "%x. x : S", and some 

1122 
predicate P that has been accidentally used as set by "{x. P x}". 

1123 
Corresponding proofs in a first step should be pruned from any 

1124 
tinkering with former theorems mem_def and Collect_def as far as 

1125 
possible. 

1126 

1127 
For developments which deliberately mix predicates and sets, a 

47464  1128 
planning step is necessary to determine what should become a predicate 
1129 
and what a set. It can be helpful to carry out that step in 

1130 
Isabelle20111 before jumping right into the current release. 

1131 

47855  1132

1133 
than predicates. INCOMPATIBILITY.

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

1136

* The representation of numerals has changed. Datatype "num" 
1138 
represents strictly positive binary numerals, along with functions 

1139 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

47855  1140 
positive and negated numeric literals, respectively. See also 
1141 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some 

1142

47855  1161 
* Transfer: New package intended to generalize the existing 
1162 
"descending" method and related theorem attributes from the Quotient 

1163 
package. (Not all functionality is implemented yet, but future 

1164 
development will focus on Transfer as an eventual replacement for the 

1165 
corresponding parts of the Quotient package.) 

47809  1166 

1167 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1168 
which relate constants at two different types. Transfer rules may 

1169 
relate different type instances of the same polymorphic constant, 

1170 
or they may relate an operation on a raw type to a corresponding 

1171 
operation on an abstract type (quotient or subtype). For example: 

1172 

1173 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1174 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1175 

1176 
 transfer method: Replaces a subgoal on abstract types with an 

1177 
equivalent subgoal on the corresponding raw types. Constants are 

1178 
replaced with corresponding ones according to the transfer rules. 

1179 
Goals are generalized over all free variables by default; this is 

47851  1180 
necessary for variables whose types change, but can be overridden 
47855  1181 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1182 
variant transfer' method allows replacing a subgoal with one that 
1183 
is logically stronger (rather than equivalent). 

1184 

1185 
 relator_eq attribute: Collects identity laws for relators of 

1186 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1187 
transfer method uses these lemmas to infer transfer rules for 

1188 
nonpolymorphic constants on the fly. 

1189 

1190 
 transfer_prover method: Assists with proving a transfer rule for a 

1191 
new constant, provided the constant is defined in terms of other 

1192 
constants that already have transfer rules. It should be applied 

1193 
after unfolding the constant definitions. 

1194 

1195 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1196 
from type nat to type int. 

1197 

47851  1198 
* Lifting: New package intended to generalize the quotient_definition 
1199 
facility of the Quotient package; designed to work with Transfer. 

47809  1200 

1201 
 lift_definition command: Defines operations on an abstract type in 

1202 
terms of a corresponding operation on a representation 

1203 
type. Example syntax: 

1204 

1205 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1206 
is List.insert 

1207 

1208 
Users must discharge a respectfulness proof obligation when each 

1209 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1210 
the proof is discharged automatically.) The obligation is 

1211 
presented in a userfriendly, readable form; a respectfulness 

1212 
theorem in the standard format and a transfer rule are generated 

1213 
by the package. 

1214 

1215 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1216 
corresponding to a datatype invariant, such as dlist), 

1217 
lift_definition generates a code certificate theorem and sets up 

1218 
code generation for each constant. 

1219 

1220 
 setup_lifting command: Sets up the Lifting package to work with a 

1221 
userdefined type. The user must provide either a quotient theorem 

1222 
or a type_definition theorem. The package configures transfer 

1223 
rules for equality and quantifiers on the type, and sets up the 

1224 
lift_definition command to work with the type. 

1225 

1226 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1227 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1228 
Word/Word.thy and Library/Float.thy. 

47809  1229 

1230 
* Quotient package: 

1231 

1232 
 The 'quotient_type' command now supports a 'morphisms' option with 

1233 
rep and abs functions, similar to typedef. 

1234 

1235 
 'quotient_type' sets up new types to work with the Lifting and 

1236 
Transfer packages, as with 'setup_lifting'. 

1237 

1238 
 The 'quotient_definition' command now requires the user to prove a 

1239 
respectfulness property at the point where the constant is 

1240 
defined, similar to lift_definition; INCOMPATIBILITY. 

1241 

1242 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

1243 
accordingly, INCOMPATIBILITY. 

1244 

1245 
* New diagnostic command 'find_unused_assms' to find potentially 

1246 
superfluous assumptions in theorems using Quickcheck. 

1247 

1248 
* Quickcheck: 

1249 

1250 
 Quickcheck returns variable assignments as counterexamples, which 

1251 
allows to reveal the underspecification of functions under test. 

1252 
For example, refuting "hd xs = x", it presents the variable 

1253 
assignment xs = [] and x = a1 as a counterexample, assuming that 

1254 
any property is false whenever "hd []" occurs in it. 

1255 

1256 
These counterexample are marked as potentially spurious, as 

1257 
Quickcheck also returns "xs = []" as a counterexample to the 

1258 
obvious theorem "hd xs = hd xs". 

1259 

1260 
After finding a potentially spurious counterexample, Quickcheck 

1261 
continues searching for genuine ones. 

1262 

1263 
By default, Quickcheck shows potentially spurious and genuine 

1264 
counterexamples. The option "genuine_only" sets quickcheck to only 

1265 
show genuine counterexamples. 

1266 

1267 
 The command 'quickcheck_generator' creates random and exhaustive 

1268 
value generators for a given type and operations. 

1269 

1270 
It generates values by using the operations as if they were 

1271 
constructors of that type. 

1272 

1273 
 Support for multisets. 

1274 

1275 
 Added "use_subtype" options. 

1276 

1277 
 Added "quickcheck_locale" configuration to specify how to process 

1278 
conjectures in a locale context. 

1279 

47855  1280 
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option 
1281 
and affecting 'rat' and 'real'. 

47809  1282 

1283 
* Sledgehammer: 

1284 
 Integrated more tightly with SPASS, as described in the ITP 2012 

1285 
paper "More SPASS with Isabelle". 

1286 
 Made it try "smt" as a fallback if "metis" fails or times out. 

1287 
 Added support for the following provers: AltErgo (via Why3 and 

1288 
TFF1), iProver, iProverEq. 

1289 
 Sped up the minimizer. 

1290 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

1291 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

1292 
 Renamed "sound" option to "strict". 

1293 

47855  1294 
* Metis: Added possibility to specify lambda translations scheme as a 
1295 
parenthesized argument (e.g., "by (metis (lifting) ...)"). 

1296 

1297 
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates". 

1298 

1299 
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY. 

47809  1300 

47856  1301 
* New "case_product" attribute to generate a case rule doing multiple 
1302 
case distinctions at the same time. E.g. 

1303 

1304 
list.exhaust [case_product nat.exhaust] 

1305 

1306 
produces a rule which can be used to perform case distinction on both 

1307 
a list and a nat. 

1308 

47809  1309 
* New "eventually_elim" method as a generalized variant of the 
47855  1310 
eventually_elim* rules. Supports structured proofs.
