* Renamed command 'print_configs' to 'print_options'. Minor 
98 
INCOMPATIBILITY. 

99 

52430  100 
* Proper diagnostic command 'print_state'. Old 'pr' (with its 
101 
implicit change of some global references) is retained for now as 

102 
control command, e.g. for ProofGeneral 3.7.x. 

103 

52549  104 
* Discontinued 'print_drafts' command with its oldfashioned PS output 
105 
and Unix commandline print spooling. Minor INCOMPATIBILITY: use 

106 
'display_drafts' instead and print via the regular document viewer. 

107 

53971  108 
* Updated and extended "isarref" and "implementation" manual, 
109 
eliminated old "ref" manual.

*** Prover IDE  Isabelle/Scala/jEdit *** 
113 

53971  114 
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or 
53852  115 
Documentation panel. 
116 

53971  117 
* Dockable window "Documentation" provides access to Isabelle 
118 
documentation. 

52646  119 

52949  120 
* Dockable window "Find" provides query operations for formal entities 
121 
(GUI frontend to 'find_theorems' command). 

122 

53050  123 
* Dockable window "Sledgehammer" manages asynchronous / parallel 
124 
sledgehammer runs over existing document sources, independently of 

125 
normal editing and checking process. 

126 

51533  127 
* Dockable window "Timing" provides an overview of relevant command 
128 
timing information. 

129 

53971  130 
* Improved dockable window "Theories": Continuous checking of proof 
131 
document (visible and required parts) may be controlled explicitly, 

132 
using check box or shortcut "C+e ENTER". Individual theory nodes may 

133 
be marked explicitly as required and checked in full, using check box 

134 
or shortcut "C+e SPACE". 

135 

136 
* Strictly monotonic document update, without premature cancellation of 

137 
running transactions that are still needed: avoid reset/restart of 

138 
such command executions while editing. 

53271

139 

53326  140 
* Improved completion mechanism, which is now managed by the 
53981  141 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 
142 
symbol abbreviations (see $ISABELLE_HOME/etc/symbols). 

53326  143 

53971  144 
* Support for asynchronous print functions, as overlay to existing 
145 
document content. 

146 

147 
* Support for automatic tools in HOL, which try to prove or disprove 

148 
toplevel theorem statements. 

149 

150 
* Action isabelle.resetfontsize resets main text area font size 

151 
according to Isabelle/Scala plugin option "jedit_font_reset_size" 

152 
(cf. keyboard shortcut C+0). 

153 

154 
* File specifications in jEdit (e.g. file browser) may refer to 

155 
$ISABELLE_HOME on all platforms. Discontinued obsolete 

156 
$ISABELLE_HOME_WINDOWS variable. 

157 

158 
* Improved support for Linux lookandfeel "GTK+", see also "Utilities 

159 
/ Global Options / Appearance". 

160 

161 
* Improved support of native Mac OS X functionality via "MacOSX" 

162 
plugin, which is now enabled by default. 

163 

51533  164 

51313  165 
*** Pure *** 
166 

54049  167 
* Commands 'interpretation' and 'sublocale' are now targetsensitive. 
168 
In particular, 'interpretation' allows for nonpersistent 

169 
interpretation within "context ... begin ... end" blocks offering a 

170 
lightweight alternative to 'sublocale'. See "isarref" manual for 

171 
details. 

51747  172 

51565  173 
* Improved locales diagnostic command 'print_dependencies'. 
174 

51313  175 
* Discontinued obsolete 'axioms' command, which has been marked as 
176 
legacy since Isabelle20092. INCOMPATIBILITY, use 'axiomatization' 

177 
instead, while observing its uniform scope for polymorphism.

183 
state of Proofterm.proofs is persistently compiled into logic images 

184 
as required, notably HOLProofs. Users no longer need to change 

185 
Proofterm.proofs dynamically. Minor INCOMPATIBILITY. 

186 

187 
* Syntax translation functions (print_translation etc.) always depend 

188 
on Proof.context. Discontinued former "(advanced)" option  this is 

189 
now the default. Minor INCOMPATIBILITY. 

190 

191 
* Former global reference trace_unify_fail is now available as 

192 
configuration option "unify_trace_failure" (global context only). 

193 

52463  194 
* SELECT_GOAL now retains the syntactic context of the overall goal 
195

208 
rather than during parsing. The data for case combinators is separated 

209

218

* Attibute 'code': 'code' now declares concrete and abstract code 
224 
equations uniformly. Use explicit 'code equation' and 'code abstract' 

225 
to distinguish both when desired. 

226 

227 
* Discontinued theories Code_Integer and Efficient_Nat by a more 

228 
finegrain stack of theories Code_Target_Int, Code_Binary_Nat, 

229 
Code_Target_Nat and Code_Target_Numeral. See the tutorial on code 

230 
generation for details. INCOMPATIBILITY. 

231 

232 
* Numeric types are mapped by default to target language numerals: 

233 
natural (replaces former code_numeral) and integer (replaces former 

234 
code_int). Conversions are available as integer_of_natural / 

235 
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and 

236 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in 

237 
ML). INCOMPATIBILITY. 

238 

239 
* Function package: For mutually recursive functions f and g, separate 

240 
cases rules f.cases and g.cases are generated instead of unusable 

241 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

242 
in the case that the unusable rule was used nevertheless.

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

245 
generated, which eliminate equalities of the form "f x = t". 

246 

247 
* New command 'fun_cases' derives adhoc elimination rules for 

248 
function equations as simplified instances of f.elims, analogous to 

249 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples. 

53307  250 

54021  251 
* Lifting: 
252 
 parametrized correspondence relations are now supported: 

253 
+ parametricity theorems for the raw term can be specified in 

254 
the command lift_definition, which allow us to generate stronger 

255 
transfer rules 

256 
+ setup_lifting generates stronger transfer rules if parametric 

257 
correspondence relation can be generated 

258 
+ various new properties of the relator must be specified to support 

259 
parametricity 

260 
+ parametricity theorem for the Quotient relation can be specified 

261 
 setup_lifting generates domain rules for the Transfer package 

262 
 stronger reflexivity prover of respectfulness theorems for type 

263 
copies 

264 
 ===> and > are now local. The symbols can be introduced 

265 
by interpreting the locale lifting_syntax (typically in an 

266 
anonymous context) 

267 
 Lifting/Transfer relevant parts of Library/Quotient_* are now in 

268 
Main. Potential INCOMPATIBILITY 

269 
 new commands for restoring and deleting Lifting/Transfer context: 

270

271 
 the command print_quotmaps was renamed to print_quot_maps. 

272 
INCOMPATIBILITY 

273 

274 
* Transfer: 

275 
 better support for domains in Transfer: replace Domainp T 

276 
by the actual invariant in a transferred goal 

277 
 transfer rules can have as assumptions other transfer rules 

278 
 Experimental support for transferring from the raw level to the 

279 
abstract level: Transfer.transferred attribute 

280 
 Attribute version of the transfer method: untransferred attribute 

281 

52286  282 
* Reification and reflection: 
53160  283 
 Reification is now directly available in HOLMain in structure 
284 
"Reification". 

285 
 Reflection now handles multiple lists with variables also. 

286 
 The whole reflection stack has been decomposed into conversions. 

52286  287 
INCOMPATIBILITY. 
288 

51489  289 
* Revised devices for recursive definitions over finite sets: 
290 
 Only one fundamental fold combinator on finite set remains: 

291 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

292 
This is now identity on infinite sets.

298 
Note that foundational constants comm_monoid_set.F and 

299 
semilattice_set.F correspond to former combinators fold_image 

300 
and fold1 respectively. These are now gone. You may use 

51490  301

INCOMPATIBILITY. 
316 

53160  317 
* Introduce type class "conditionally_complete_lattice": Like a 
318 
complete lattice but does not assume the existence of the top and 

319 
bottom elements. Allows to generalize some lemmas about reals and 

320 
extended reals. Removed SupInf and replaced it by the instantiation 

321 
of conditionally_complete_lattice for real. Renamed lemmas about 

322 
conditionallycomplete lattice from Sup_... to cSup_... and from 

323 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

324 
lemmas. 

325 

326

327 
conditionallycomplete lattices and inner dense linorders which have 

328 
more than one element. INCOMPATIBILITY. 

329 

53983  330

331

332 
Rename bot > order_bot, top > order_top 

53683  333 

53160  334 
* Introduce type classes "no_top" and "no_bot" for orderings without 
335 
top and bottom elements. 

51732  336 

337 
* Split dense_linorder into inner_dense_order and no_top, no_bot.

53160  340 
HOLMultivariate_Analysis to HOLComplex_Main. 
51732  341 

53983  342 
 Introduce type class (lin)order_topology and 
343 
linear_continuum_topology. Allows to generalize theorems about 

344

51732  345 

346 
 continuous and continuos_on from Multivariate_Analysis: 

53983  347 
"continuous" is the continuity of a function at a filter. "isCont" 
348 
is now an abbrevitation: "isCont x f == continuous (at _) f". 

349 

350 
Generalized continuity lemmas from isCont to continuous on an 

351 
arbitrary filter. 

352 

353 
 compact from Multivariate_Analysis. Use Bolzano's lemma to prove 

354 
compactness of closed intervals on reals. Continuous functions 

355 
attain infimum and supremum on compact sets. The inverse of a 

356 
continuous function is continuous, when the function is continuous 

357 
on a compact set.

367 
 FDERIV: Definition of has_derivative moved to Deriv.thy. Moved 

368 
theorems from Library/FDERIV.thy to Deriv.thy and base the 

369 
definition of DERIV on FDERIV. Add variants of DERIV and FDERIV 

370 
which are restricted to sets, i.e. to represent derivatives from 

371 
left or right. 

51732  372 

373 
 Removed the withinfilter. It is replaced by the principal filter: 

374 

375 
F within X = inf F (principal X) 

376 

377 
 Introduce "at x within U" as a single constant, "at x" is now an 

378 
abbreviation for "at x within UNIV" 

379 

53983  380 
 Introduce named theorem collections tendsto_intros, 
381 
continuous_intros, continuous_on_intros and FDERIV_intros. Theorems 

382 
in tendsto_intros (or FDERIV_intros) are also available as 

383 
tendsto_eq_intros (or FDERIV_eq_intros) where the righthand side 

384 
is replaced by a congruence rule. This allows to apply them as 

385 
intro rules and then proving equivalence by the simplifier.

*** Prover IDE  Isabelle/Scala/jEdit *** 
612 

613 
* Parallel terminal proofs ('by') are enabled by default, likewise 

614 
proofs that are built into packages like 'datatype', 'function'. This 

615 
allows to "run ahead" checking the theory specifications on the 

616 
surface, while the prover is still crunching on internal 

617 
justifications. Unfinished / cancelled proofs are restarted as 

618 
required to complete full proof checking eventually. 

619 

620 
* Improved output panel with tooltips, hyperlinks etc. based on the 

621 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

622 
tooltips leads to some window that supports the same recursively, 

623 
which can lead to stacks of tooltips as the semantic document content 

624 
is explored. ESCAPE closes the whole stack, individual windows may be 

625 
closed separately, or detached to become independent jEdit dockables. 

626 

50717  627 
* Improved support for commands that produce graph output: the text 
628 
message contains a clickable area to open a new instance of the graph 

629 
browser on demand. 

630 

49968  631 
* More robust incremental parsing of outer syntax (partial comments, 
632 
malformed symbols). Changing the balance of open/close quotes and 

633 
comment delimiters works more conveniently with unfinished situations 

634 
that frequently occur in user interaction. 

635 

636 
* More efficient painting and improved reactivity when editing large 

637

commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  1089 

47829  1090 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
1091 
declaration, and results are standardized before being stored. Thus 

1092 
oldstyle "standard" after instantiation or composition of facts 

1093 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

1094 
indices of schematic variables. 

1095 

1096 
* Rule attributes in local theory declarations (e.g. locale or class) 

1097 
are now statically evaluated: the resulting theorem is stored instead 

1098 
of the original expression. INCOMPATIBILITY in rare situations, where 

1099 
the historic accident of dynamic reevaluation in interpretations 

1100 
etc. was exploited. 

1101 

1102 
* New tutorial "Programming and Proving in Isabelle/HOL" 

1103 
("progprove"). It completely supersedes "A Tutorial Introduction to 

1104 
Structured Isar Proofs" ("isaroverview"), which has been removed. It 

1105 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

1106 
Logic" as the recommended beginners tutorial, but does not cover all 

1107 
of the material of that old tutorial. 

1108 

1109 
* Updated and extended reference manuals: "isarref", 

1110 
"implementation", "system"; reduced remaining material in old "ref" 

1111 
manual.

47855  1120 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
1121 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

1122 
expand it. This also works for objectlogic equality. (Formerly 

1123 
undocumented feature.) 

1124 

47856  1125 
* Sort constraints are now propagated in simultaneous statements, just 
1126 
like type constraints. INCOMPATIBILITY in rare situations, where 

1127 
distinct sorts used to be assigned accidentally. For example: 

1128 

1129 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

1130 

1131 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

1132 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

1133 

1134 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

1135 
tolerant against multiple unifiers, as long as the final result is 

1136 
unique. (As before, rules are composed in canonical righttoleft 

1137 
order to accommodate newly introduced premises.) 

1138 

47806  1139 
* Renamed some inner syntax categories: 
1140 

1141 
num ~> num_token 

1142 
xnum ~> xnum_token 

1143 
xstr ~> str_token 

1144 

1145 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

1146 
"num_position" etc. are mainly used instead (which also include 

1147 
position information via constraints). 

1148 

47829  1149 
* Simplified configuration options for syntax ambiguity: see 
1150

1151 
manual. Minor INCOMPATIBILITY. 

1152 

47856  1153 
* Discontinued configuration option "syntax_positions": atomic terms 
1154

47464  1180 
* Type 'a set is now a proper type constructor (just as before 
1181 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

1182 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  1183 
sets separate, it is often sufficient to rephrase some set S that has 
1184 
been accidentally used as predicates by "%x. x : S", and some 

1185 
predicate P that has been accidentally used as set by "{x. P x}". 

1186 
Corresponding proofs in a first step should be pruned from any 

1187 
tinkering with former theorems mem_def and Collect_def as far as 

1188 
possible. 

1189 

1190 
For developments which deliberately mix predicates and sets, a 

47464  1191 
planning step is necessary to determine what should become a predicate 
1192 
and what a set. It can be helpful to carry out that step in 

1193 
Isabelle20111 before jumping right into the current release. 

1194

1202 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

47855  1203 
positive and negated numeric literals, respectively. See also 
1204 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some

47855  1224 
* Transfer: New package intended to generalize the existing 
1225 
"descending" method and related theorem attributes from the Quotient 

1226 
package. (Not all functionality is implemented yet, but future 

1227 
development will focus on Transfer as an eventual replacement for the 

1228 
corresponding parts of the Quotient package.) 

47809  1229 

1230 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1231 
which relate constants at two different types. Transfer rules may 

1232 
relate different type instances of the same polymorphic constant, 

1233 
or they may relate an operation on a raw type to a corresponding 

1234 
operation on an abstract type (quotient or subtype). For example: 

1235 

1236 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1237 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1238 

1239 
 transfer method: Replaces a subgoal on abstract types with an 

1240 
equivalent subgoal on the corresponding raw types. Constants are 

1241 
replaced with corresponding ones according to the transfer rules. 

1242 
Goals are generalized over all free variables by default; this is 

47851  1243 
necessary for variables whose types change, but can be overridden 
47855  1244 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1245 
variant transfer' method allows replacing a subgoal with one that 
1246 
is logically stronger (rather than equivalent). 

1247 

1248 
 relator_eq attribute: Collects identity laws for relators of 

1249 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1250 
transfer method uses these lemmas to infer transfer rules for 

1251 
nonpolymorphic constants on the fly. 

1252 

1253 
 transfer_prover method: Assists with proving a transfer rule for a 

1254 
new constant, provided the constant is defined in terms of other 

1255 
constants that already have transfer rules. It should be applied 

1256 
after unfolding the constant definitions. 

1257 

1258 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1259 
from type nat to type int. 

1260 

47851  1261 
* Lifting: New package intended to generalize the quotient_definition 
1262 
facility of the Quotient package; designed to work with Transfer. 

47809  1263 

1264 
 lift_definition command: Defines operations on an abstract type in 

1265 
terms of a corresponding operation on a representation 

1266 
type. Example syntax: 

1267 

1268 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1269 
is List.insert 

1270 

1271 
Users must discharge a respectfulness proof obligation when each 

1272 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1273 
the proof is discharged automatically.) The obligation is 

1274 
presented in a userfriendly, readable form; a respectfulness 

1275 
theorem in the standard format and a transfer rule are generated 

1276 
by the package. 

1277 

1278 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1279 
corresponding to a datatype invariant, such as dlist), 

1280 
lift_definition generates a code certificate theorem and sets up 

1281 
code generation for each constant. 

1282 

1283 
 setup_lifting command: Sets up the Lifting package to work with a 

1284 
userdefined type. The user must provide either a quotient theorem 

1285 
or a type_definition theorem. The package configures transfer 

1286 
rules for equality and quantifiers on the type, and sets up the 

1287 
lift_definition command to work with the type. 

1288 

1289 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1290 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1291 
Word/Word.thy and Library/Float.thy. 

47809  1292 

1293 
* Quotient package: 

1294 

1295 
 The 'quotient_type' command now supports a 'morphisms' option with 

1296 
rep and abs functions, similar to typedef. 

1297 

1298 
 'quotient_type' sets up new types to work with the Lifting and 

1299 
Transfer packages, as with 'setup_lifting'. 

1300 

1301 
 The 'quotient_definition' command now requires the user to prove a 

1302 
respectfulness property at the point where the constant is 

1303 
defined, similar to lift_definition; INCOMPATIBILITY. 

1304 

1305 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

1306 
accordingly, INCOMPATIBILITY. 

1307 

1308 
* New diagnostic command 'find_unused_assms' to find potentially 

1309 
superfluous assumptions in theorems using Quickcheck. 

1310 

1311 
* Quickcheck: 

1312 

1313 
 Quickcheck returns variable assignments as counterexamples, which 

1314 
allows to reveal the underspecification of functions under test. 

1315 
For example, refuting "hd xs = x", it presents the variable 

1316 
assignment xs = [] and x = a1 as a counterexample, assuming that 

1317 
any property is false whenever "hd []" occurs in it. 

1318 

1319 
These counterexample are marked as potentially spurious, as 

1320 
Quickcheck also returns "xs = []" as a counterexample to the 

1321 
obvious theorem "hd xs = hd xs". 

1322 

1323 
After finding a potentially spurious counterexample, Quickcheck 

1324 
continues searching for genuine ones. 

1325 

1326 
By default, Quickcheck shows potentially spurious and genuine 

1327 
counterexamples. The option "genuine_only" sets quickcheck to only 

1328 
show genuine counterexamples. 

1329 

1330 
 The command 'quickcheck_generator' creates random and exhaustive 

1331 
value generators for a given type and operations. 

1332 

1333 
It generates values by using the operations as if they were 

1334 
constructors of that type. 

1335 

1336 
 Support for multisets. 

1337 

1338 
 Added "use_subtype" options. 

1339 

1340 
 Added "quickcheck_locale" configuration to specify how to process 

1341 
conjectures in a locale context. 

1342 

47855  1343 
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option 
1344 
and affecting 'rat' and 'real'. 

47809  1345 

1346 
* Sledgehammer: 

1347 
 Integrated more tightly with SPASS, as described in the ITP 2012 

1348 
paper "More SPASS with Isabelle". 

1349 
 Made it try "smt" as a fallback if "metis" fails or times out. 

1350 
 Added support for the following provers: AltErgo (via Why3 and 

1351 
TFF1), iProver, iProverEq. 

1352 
 Sped up the minimizer. 

1353 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

1354 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

1355 
 Renamed "sound" option to "strict". 

1356 

47855  1357 
* Metis: Added possibility to specify lambda translations scheme as a 
1358 
parenthesized argument (e.g., "by (metis (lifting) ...)"). 

1359 

1360 
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates". 

1361 

1362 
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY. 

47809  1363 

47856  1364 
* New "case_product" attribute to generate a case rule doing multiple 
1365 
case distinctions at the same time. E.g. 

1366 

1367 
list.exhaust [case_product nat.exhaust] 

1368 

1369 
produces a rule which can be used to perform case distinction on both 

1370 
a list and a nat. 

1371 

47809  1372 
* New "eventually_elim" method as a generalized variant of the 
47855  1373 
eventually_elim* rules. Supports structured proofs.
