 support for userdefined Isar commands within the running session 
47158  16 
 improved support for Unicode outside original 16bit range 
17 
e.g. glyph for \<A> (thanks to jEdit 4.5.1)

* Forward declaration of outer syntax keywords within the theory 
20 
header  minor INCOMPATIBILITY for userdefined commands. Allow new 

21 
commands to be used in the same theory where defined. 

46485  22 

45593  23 
* Rule attributes in local theory declarations (e.g. locale or class) 
24 
are now statically evaluated: the resulting theorem is stored instead 

25 
of the original expression. INCOMPATIBILITY in rare situations, where 

26 
the historic accident of dynamic reevaluation in interpretations 

27 
etc. was exploited.

*** HOL *** 
133 

47806  134 
* New tutorial "Programming and Proving in Isabelle/HOL" 
135 
("progprove"). It completely supersedes "A Tutorial Introduction to 

136 
Structured Isar Proofs" ("isaroverview"), which has been removed. It 

137 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

138 
Logic" as the recommended beginners tutorial, but does not cover all 

139 
of the material of that old tutorial. 

47464  140 

141 
* Type 'a set is now a proper type constructor (just as before 

142 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

143 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

144 
sets separate, it is often sufficient to rephrase sets S accidentally 

145 
used as predicates by "%x. x : S" and predicates P accidentally used 

146 
as sets by "{x. P x}". Corresponding proofs in a first step should be 

147 
pruned from any tinkering with former theorems mem_def and Collect_def 

148 
as far as possible. 

149 

150 
For developments which deliberately mixed predicates and sets, a 

151 
planning step is necessary to determine what should become a predicate 

152 
and what a set. It can be helpful to carry out that step in 

153 
Isabelle20111 before jumping right into the current release. 

154 

155 
* The representation of numerals has changed. Datatype "num" 

156 
represents strictly positive binary numerals, along with functions 

157 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

158 
positive and negated numeric literals, respectively. (See definitions 

159 
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories 

160 
may require adaptations as follows:

46373  187 
* New type synonym 'a rel = ('a * 'a) set 
188 

47809  189 
* New "case_product" attribute to generate a case rule doing multiple 
190 
case distinctions at the same time. E.g. 

191 

192 
list.exhaust [case_product nat.exhaust] 

193 

194 
produces a rule which can be used to perform case distinction on both 

195 
a list and a nat. 

196 

197 
* New Transfer package: 

198 

199 
 transfer_rule attribute: Maintains a collection of transfer rules, 

200 
which relate constants at two different types. Transfer rules may 

201 
relate different type instances of the same polymorphic constant, 

202 
or they may relate an operation on a raw type to a corresponding 

203 
operation on an abstract type (quotient or subtype). For example: 

204 

205 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

206 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

207 

208 
 transfer method: Replaces a subgoal on abstract types with an 

209 
equivalent subgoal on the corresponding raw types. Constants are 

210 
replaced with corresponding ones according to the transfer rules. 

211 
Goals are generalized over all free variables by default; this is 

212 
necessary for variables whose types changes, but can be overridden 

213 
for specific variables with e.g. 'transfer fixing: x y z'. The 

214 
variant transfer' method allows replacing a subgoal with one that 

215 
is logically stronger (rather than equivalent). 

216 

217 
 relator_eq attribute: Collects identity laws for relators of 

218 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

219 
transfer method uses these lemmas to infer transfer rules for 

220 
nonpolymorphic constants on the fly. 

221 

222 
 transfer_prover method: Assists with proving a transfer rule for a 

223 
new constant, provided the constant is defined in terms of other 

224 
constants that already have transfer rules. It should be applied 

225 
after unfolding the constant definitions. 

226 

227 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

228 
from type nat to type int. 

229 

230 
* New Lifting package: 

231 

232 
 lift_definition command: Defines operations on an abstract type in 

233 
terms of a corresponding operation on a representation 

234 
type. Example syntax: 

235 

236 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

237 
is List.insert 

238 

239 
Users must discharge a respectfulness proof obligation when each 

240 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

241 
the proof is discharged automatically.) The obligation is 

242 
presented in a userfriendly, readable form; a respectfulness 

243 
theorem in the standard format and a transfer rule are generated 

244 
by the package. 

245 

246 
 Integration with code_abstype: For typedefs (e.g. subtypes 

247 
corresponding to a datatype invariant, such as dlist), 

248 
lift_definition generates a code certificate theorem and sets up 

249 
code generation for each constant. 

250 

251 
 setup_lifting command: Sets up the Lifting package to work with a 

252 
userdefined type. The user must provide either a quotient theorem 

253 
or a type_definition theorem. The package configures transfer 

254 
rules for equality and quantifiers on the type, and sets up the 

255 
lift_definition command to work with the type. 

256 

257 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

258 
Quotient_Examples/Lift_RBT.thy, Word/Word.thy and 

259 
Library/Float.thy. 

260 

261 
* Quotient package: 

262 

263 
 The 'quotient_type' command now supports a 'morphisms' option with 

264 
rep and abs functions, similar to typedef. 

265 

266 
 'quotient_type' sets up new types to work with the Lifting and 

267 
Transfer packages, as with 'setup_lifting'. 

268 

269 
 The 'quotient_definition' command now requires the user to prove a 

270 
respectfulness property at the point where the constant is 

271 
defined, similar to lift_definition; INCOMPATIBILITY. 

272 

273 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

274 
accordingly, INCOMPATIBILITY. 

275 

276 
* New diagnostic command 'find_unused_assms' to find potentially 

277 
superfluous assumptions in theorems using Quickcheck. 

278 

279 
* Quickcheck: 

280 

281 
 Quickcheck returns variable assignments as counterexamples, which 

282 
allows to reveal the underspecification of functions under test. 

283 
For example, refuting "hd xs = x", it presents the variable 

284 
assignment xs = [] and x = a1 as a counterexample, assuming that 

285 
any property is false whenever "hd []" occurs in it. 

286 

287 
These counterexample are marked as potentially spurious, as 

288 
Quickcheck also returns "xs = []" as a counterexample to the 

289 
obvious theorem "hd xs = hd xs". 

290 

291 
After finding a potentially spurious counterexample, Quickcheck 

292 
continues searching for genuine ones. 

293 

294 
By default, Quickcheck shows potentially spurious and genuine 

295 
counterexamples. The option "genuine_only" sets quickcheck to only 

296 
show genuine counterexamples. 

297 

298 
 The command 'quickcheck_generator' creates random and exhaustive 

299 
value generators for a given type and operations. 

300 

301 
It generates values by using the operations as if they were 

302 
constructors of that type. 

303 

304 
 Support for multisets. 

305 

306 
 Added "use_subtype" options. 

307 

308 
 Added "quickcheck_locale" configuration to specify how to process 

309 
conjectures in a locale context. 

310 

311 
* Nitpick: 

312 
 Fixed infinite loop caused by the 'peephole_optim' option and 

313 
affecting 'rat' and 'real'. 

314 

315 
* Sledgehammer: 

316 
 Integrated more tightly with SPASS, as described in the ITP 2012 

317 
paper "More SPASS with Isabelle". 

318 
 Made it try "smt" as a fallback if "metis" fails or times out. 

319 
 Added support for the following provers: AltErgo (via Why3 and 

320 
TFF1), iProver, iProverEq. 

321 
 Replaced remote ESInE with remote Satallax in the default setup. 

322 
 Sped up the minimizer. 

323 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

324 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

325 
 Renamed "sound" option to "strict". 

326 

327 
* Metis: 

328 
 Added possibility to specify lambda translations scheme as a 

329 
parenthesized argument (e.g., "by (metis (lifting) ...)"). 

330 

331 
* SMT: 

332 
 Renamed "smt_fixed" option to "smt_read_only_certificates". 

333 

334 
* Command 'try0': 

335 
 Renamed from 'try_methods'. INCOMPATIBILITY. 

336 

337 
* New "eventually_elim" method as a generalized variant of the 

338 
eventually_elim* rules. Supports structured proofs.

* Session HOLWord: New proof method "word_bitwise" for splitting 
804 
machine word equalities and inequalities into logical circuits, 

805 
defined in HOL/Word/WordBitwise.thy. Supports addition, subtraction, 

806 
multiplication, shifting by constants, bitwise operators and numeric 

807 
constants. Requires fixedlength word types, not 'a word. Solves 

808 
many standard word identies outright and converts more into first

order problems amenable to blast or similar. See also examples in

* Session HOLProbability: Introduced the type "'a measure" to 
813 
represent measures, this replaces the records 'a algebra and 'a 

814 
measure_space. The locales based on subset_class now have two 

815 
localeparameters the space \<Omega> and the set of measurables sets 

816 
M. The product of probability spaces uses now the same constant as 

817 
the finite product of sigmafinite measure spaces "PiM :: ('i => 'a) 

818 
measure". Most constants are defined now outside of locales and gain 

819 
an additional parameter, like null_sets, almost_eventually or \<mu>'. 

820 
Measure space constructions for distributions and densities now got 

821 
their own constants distr and density. Instead of using locales to 

822 
describe measure spaces with a finite space, the measure count_space 

823

* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as 
44968  1076 
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  1077

 Management of multiple theory files directly from the editor 
44760  1079 
buffer store  bypassing the filesystem (no requirement to save 
1080 
files for checking). 

1081 

44777  1082 
 Markup of formal entities within the text buffer, with semantic 
44760  1083 
highlighting, tooltips and hyperlinks to jump to defining source 
1084 
positions. 

1085 

44777  1086 
 Improved text rendering, with sub/superscripts in the source 
1087 
buffer (including support for copy/paste wrt. output panel, HTML 

1088 
theory output and other nonIsabelle text boxes). 

1089 

1090 
 Refined scheduling of proof checking and printing of results, 

44760  1091 
based on interactive editor view. (Note: jEdit folding and 
1092 
narrowing allows to restrict buffer perspectives explicitly.) 

1093 

44777  1094 
 Reduced CPU performance requirements, usable on machines with few 
44760  1095 
cores. 
1096 

44777  1097 
 Reduced memory requirements due to pruning of unused document 
44760  1098 
versions (garbage collection).

1105 
The global load path (such as src/HOL/Library) has been discontinued. 

1106 
Note that the path element ~~ may be used to reference theories in the 

1107 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet".

* Theory Complex_Main: The definition of infinite series was 
1328 
generalized. Now it is defined on the type class {topological_space, 

1329 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  1330 

44908  1331 
* Theory Complex_Main: The complex exponential function "expi" is now 
1332 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

1333 
several polymorphic lemmas about "exp" are now applicable to "expi". 

1334 

44968  1335 
* Code generation: 
1336 

1337 
 Theory Library/Code_Char_ord provides native ordering of 

1338 
characters in the target language. 

1339 

1340 
 Commands code_module and code_library are legacy, use export_code 

1341 
instead. 

1342 

1343 
 Method "evaluation" is legacy, use method "eval" instead. 

1344 

1345 
 Legacy evaluator "SML" is deactivated by default. May be 

1346 
reactivated by the following theory command: 

1347 

1348 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

1349 

1350 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

1351 

45088  1352 
* New proof method "induction" that gives induction hypotheses the 
1353 
name "IH", thus distinguishing them from further hypotheses that come 

1354 
from rule induction. The latter are still called "hyps". Method 

1355 
"induction" is a thin wrapper around "induct" and follows the same 

1356 
syntax. 

1357 

44968  1358 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
1359 
still available as a legacy feature for some time. 

1360 

1361 
* Nitpick: 

1362 
 Added "need" and "total_consts" options. 

1363 
 Reintroduced "show_skolems" option by popular demand.

 Renamed attribute: nitpick_def ~> nitpick_unfold.

 Use quasisound (and efficient) translations by default. 

1369 
 Added support for the following provers: EToFoF, LEOII, 

1370 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

1371 
 Automatically preplay and minimize proofs before showing them if 

1372 
this can be done within reasonable time. 

1373 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

1374 
INCOMPATIBILITY. 

1375 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

1376 
"max_mono_iters", and "max_new_mono_instances" options. 

1377 
 Removed "explicit_apply" and "full_types" options as well as "Full 

1378 
Types" Proof General menu item. INCOMPATIBILITY.

* Metis: 

1381 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

1382 
 Obsoleted "metisFT"  use "metis (full_types)" instead.

1385 
* Command 'try': 

1386 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

1387 
"elim:" options. INCOMPATIBILITY. 

1388 
 Introduced 'try' that not only runs 'try_methods' but also 

1389 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

1390 

1391 
* Quickcheck: 

1392 
 Added "eval" option to evaluate terms for the found counterexample 

1393 
(currently only supported by the default (exhaustive) tester). 

1394 
 Added postprocessing of terms to obtain readable counterexamples 

1395 
(currently only supported by the default (exhaustive) tester). 

1396 
 New counterexample generator quickcheck[narrowing] enables 

1397 
narrowingbased testing. Requires the Glasgow Haskell compiler 

1398 
with its installation location defined in the Isabelle settings 

1399 
environment as ISABELLE_GHC. 

1400 
 Removed quickcheck tester "SML" based on the SML code generator 

1401 
(formly in HOL/Library).

* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

1404 
use 'partial_function' instead. 

1405 

1406 
* Theory Library/Extended_Reals replaces now the positive extended 

1407 
reals found in probability theory. This file is extended by 

1408 
Multivariate_Analysis/Extended_Real_Limits. 

1409 

44974  1410 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
1411 
from where it must be imported explicitly if it is really required. 

1412 
INCOMPATIBILITY. 

44968  1413 

1414 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has
