* Simplified outer syntax: uniform category "name" includes long 
24 
identifiers. Former "xname" / "nameref" / "name reference" has been 

25 
discontinued. 

26 

62807  27 
* Mixfix annotations support general block properties, with syntax 
28 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

29 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

30 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

31 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  32 

62440  33 
* New symbol \<circle>, e.g. for temporal operator. 
34 

62453  35 
* Old 'header' command is no longer supported (legacy since 
36 
Isabelle2015).

*** Prover IDE  Isabelle/Scala/jEdit *** 
40 

63135  41 
* Cartouche abbreviations work both for " and ` to accomodate typical 
42 
situations where old ASCII notation may be updated. 

43 

63022  44 
* IDE support for the Isabelle/Pure bootstrap process, with the 
45 
following independent stages: 

46 

47 
src/Pure/ROOT0.ML 

48 
src/Pure/ROOT.ML 

49 
src/Pure/Pure.thy 

50 
src/Pure/ML_Bootstrap.thy 

51 

52 
The ML ROOT files act like quasitheories in the context of theory 

53 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

54 
The theory files are presented with a modified header to import Pure 

55 
from the running Isabelle instance. Results from changed versions of 

56 
each stage are *not* propagated to the next stage, and isolated from the 

57 
actual Isabelle/Pure that runs the IDE itself. The sequential 

58 
dependencies of the above files are only relevant for batch build.

optional abstraction over local parameters. The syntax resembles

'definition' and 'obtain'. It fits better into the Isar language than

502 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

503 
'SML_file_no_debug' control compilation of sources with or without 

504 
debugging information. The Debugger panel allows to set breakpoints (via 

505 
context menu), step through stopped threads, evaluate local ML 

506 
expressions etc. At least one Debugger view needs to be active to have 

507 
any effect on the running ML program.

* The State panel manages explicit proof state output, with dynamic 
510

511 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

512 
update. 

61729  513 

514 
* The Output panel no longer shows proof state output by default, to 

515 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

516 
enable option "editor_output_state". 

61215  517 

61803  518 
* The text overview column (status of errors, warnings etc.) is updated 
519 
asynchronously, leading to much better editor reactivity. Moreover, the 

520 
full document node content is taken into account. The width of the 

521 
column is scaled according to the main text area font, for improved 

522 
visibility. 

523 

524 
* The main text area no longer changes its color hue in outdated 

525 
situations. The text overview column takes over the role to indicate 

526 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

527 
due to adhoc updates by auxiliary GUI components, such as the State 

528 
panel.

The local assumptions are bound to the name "that". The result is 
650

corresponds to a raw proof block like this:

61733  663 
* Assumptions ('assume', 'presume') allow structured rule statements 
664 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  665 

666 
assume result: "C x y" 

667 
if "A x" and "B y" 

668 
for x :: 'a and y :: 'a 

669 

670 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

671 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

672 

673 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

674 
only effects propositions according to actual use of variables. For 

675 
example: 

676 

677 
assume "A x" and "B y" for x and y 

678 

679 
is equivalent to: 

680 

681 
assume "\<And>x. A x" and "\<And>y. B y" 

682 

60595  683 
* The meaning of 'show' with Pure rule statements has changed: premises 
684 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  685 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
686 
follows: 

60595  687 

688 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

689 

690 
or: 

691 

692 
show "C x" if "A x" "B x" for x 

693 

694 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

695 

696 
show "C x" when "A x" "B x" for x 

697 

60459  698 
* New command 'consider' states rules for generalized elimination and 
699 
case splitting. This is like a toplevel statement "theorem obtains" used 

700 
within a proof body; or like a multibranch 'obtain' without activation 

701 
of the local context elements yet. 

702 

60455  703 
* Proof method "cases" allows to specify the rule as first entry of 
704 
chained facts. This is particularly useful with 'consider': 

705 

706 
consider (a) A  (b) B  (c) C <proof> 

707 
then have something 

708

709

60565  719 
* Command 'case' allows fact name and attribute specification like this: 
720 

721 
case a: (c xs) 

722 
case a [attributes]: (c xs) 

723 

724 
Facts that are introduced by invoking the case context are uniformly 

725 
qualified by "a"; the same name is used for the cumulative fact. The old 

726 
form "case (c xs) [attributes]" is no longer supported. Rare 

727 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

728 
and always put attributes in front.

profile_time_thread (*CPU time on this thread*)

1187 
improved: proper treatment of break offsets and blocks with consistent 

1188

1189 

61268  1190

Drule.infer_instantiate (*instantiation with type inference*) 

1206 
Drule.infer_instantiate' (*version with positional arguments*) 

1207

Old cterm_instantiate is superseded by infer_instantiate. 

1210 
INCOMPATIBILITY, need to readjust some ML names and types accordingly.

* Command 'experiment' opens an anonymous locale context with private 
1309 
naming policy. 

1310 

59951  1311 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1312 
structure in the body: 'oops' is no longer supported here. Minor 

1313 
INCOMPATIBILITY, use 'sorry' instead. 

1314 

1315 
* Command 'named_theorems' declares a dynamic fact within the context, 

1316 
together with an attribute to maintain the content incrementally. This 

1317 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1318 
of semantics due to external visual order vs. internal reverse order. 

1319 

1320 
* 'find_theorems': search patterns which are abstractions are 

1321 
schematically expanded before search. Search results match the naive 

1322 
expectation more closely, particularly wrt. abbreviations.

INCOMPATIBILITY.

* Improved folding mode "isabelle" based on Isar syntax. Alternatively, 
1352 
the "sidekick" mode may be used for document structure. 

1353 

1354 
* Extended bracket matching based on Isar language structure. System 

1355 
option jedit_structure_limit determines maximum number of lines to scan 

1356 
in the buffer. 

58758  1357

* Support for BibTeX files: context menu, contextsensitive token 
1359 
marker, SideKick parser. 

58524  1360 

58551  1361 
* Document antiquotation @{cite} provides formal markup, which is 
60265  1362 
interpreted semiformally based on .bib files that happen to be open in 
1363 
the editor (hyperlinks, completion etc.).

*** Document preparation *** 
1379 

1380 
* Document markup commands 'chapter', 'section', 'subsection', 

1381 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1382 
context, even before the initial 'theory' command. Obsolete proof 

1383 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1384 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1385 
instead. The old 'header' command is still retained for some time, but 

1386 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1387 
update_header"). Minor INCOMPATIBILITY. 

1388 

60009  1389 
* Official support for "tt" style variants, via \isatt{...} or 
1390 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1391 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1392 
as argument to other macros (such as footnotes). 

1393 

1394 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1395 
style. 

1396 

1397 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1398 
produced unconditionally for HTML browser_info and PDFLaTeX document.
