62969  23 
* 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is superseded by "(\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). 

37 

63273  38 
* Command 'bundle' provides a local theory target to define a bundle 
39 
from the body of specification commands (such as 'declare', 

40 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

41 

42 
bundle foo 

43 
begin 

44 
declare a [simp] 

45 
declare b [intro] 

46 
end 

63272  47 

63282  48 
* Command 'unbundle' is like 'include', but works within a local theory 
49 
context. Unlike "context includes ... begin", the effect of 'unbundle' 

50 
on the target context persists, until different declarations are given. 

51 

63383  52 
* Proof method "blast" is more robust wrt. corner cases of Pure 
53 
statements without objectlogic judgment.

*** Prover IDE  Isabelle/Scala/jEdit *** 
65 

63135  66 
* Cartouche abbreviations work both for " and ` to accomodate typical 
67 
situations where old ASCII notation may be updated. 

68 

63610  69 
* Isabelle/ML and Standard ML files are presented in Sidekick with the 
70 
tree structure of section headings: this special comment format is 

71 
described in "implementation" chapter 0, e.g. (*** section ***). 

72 

63022  73 
* IDE support for the Isabelle/Pure bootstrap process, with the 
74 
following independent stages: 

75 

76 
src/Pure/ROOT0.ML 

77 
src/Pure/ROOT.ML 

78 
src/Pure/Pure.thy 

79 
src/Pure/ML_Bootstrap.thy 

80 

81 
The ML ROOT files act like quasitheories in the context of theory 

82 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

83 
The theory files are presented with a modified header to import Pure 

84 
from the running Isabelle instance. Results from changed versions of 

85 
each stage are *not* propagated to the next stage, and isolated from the 

86 
actual Isabelle/Pure that runs the IDE itself. The sequential 

63307  87 
dependencies of the above files are only observed for batch build.

128 
before. The theory syntax for 'keywords' has been simplified 

129 
accordingly: optional abbrevs need to go into the new 'abbrevs' section.

136 

137 
* Commands 'finally' and 'ultimately' used to expose the result as

784 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

785 
'SML_file_no_debug' control compilation of sources with or without 

786 
debugging information. The Debugger panel allows to set breakpoints (via 

787 
context menu), step through stopped threads, evaluate local ML 

788 
expressions etc. At least one Debugger view needs to be active to have 

789 
any effect on the running ML program. 

60984  790

* The State panel manages explicit proof state output, with dynamic 
792 
autoupdate according to cursor movement. Alternatively, the jEdit 

793 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

794 
update. 

61729  795 

796 
* The Output panel no longer shows proof state output by default, to 

797 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

798 
enable option "editor_output_state". 

61215  799 

61803  800 
* The text overview column (status of errors, warnings etc.) is updated 
801 
asynchronously, leading to much better editor reactivity. Moreover, the 

802 
full document node content is taken into account. The width of the 

803 
column is scaled according to the main text area font, for improved 

804 
visibility. 

805 

806 
* The main text area no longer changes its color hue in outdated 

807 
situations. The text overview column takes over the role to indicate 

808 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

809 
due to adhoc updates by auxiliary GUI components, such as the State 

810 
panel.

The local assumptions are bound to the name "that". The result is 
935

60414  936 
corresponds to a raw proof block like this:

947 

61733  948 
* Assumptions ('assume', 'presume') allow structured rule statements 
949 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  950 

951 
assume result: "C x y" 

952 
if "A x" and "B y" 

953 
for x :: 'a and y :: 'a 

954 

955 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

956 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

957 

958 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

959 
only effects propositions according to actual use of variables. For 

960 
example: 

961 

962 
assume "A x" and "B y" for x and y 

963 

964 
is equivalent to: 

965 

966 
assume "\<And>x. A x" and "\<And>y. B y" 

967 

60595  968 
* The meaning of 'show' with Pure rule statements has changed: premises 
969 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  970 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
971 
follows: 

60595  972 

973 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

974 

975 
or: 

976 

977 
show "C x" if "A x" "B x" for x 

978 

979 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

980 

981 
show "C x" when "A x" "B x" for x 

982 

60459  983 
* New command 'consider' states rules for generalized elimination and 
984 
case splitting. This is like a toplevel statement "theorem obtains" used 

985 
within a proof body; or like a multibranch 'obtain' without activation 

986 
of the local context elements yet. 

987 

60455  988 
* Proof method "cases" allows to specify the rule as first entry of 
989 
chained facts. This is particularly useful with 'consider': 

990 

991 
consider (a) A  (b) B  (c) C <proof> 

992 
then have something 

993

* Command 'case' allows fact name and attribute specification like this: 
1005 

1006 
case a: (c xs) 

1007 
case a [attributes]: (c xs) 

1008 

1009 
Facts that are introduced by invoking the case context are uniformly 

1010 
qualified by "a"; the same name is used for the cumulative fact. The old 

1011 
form "case (c xs) [attributes]" is no longer supported. Rare 

1012

semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute 
1350 
and gcd_int.commute are subsumed by gcd.commute, as well as 

1351 
gcd_nat.assoc and gcd_int.assoc by gcd.assoc.

* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are 

1354 
logically unified to Rings.divide in syntactic type class Rings.divide, 

1355 
with infix syntax (_ div _). Infix syntax (_ / _) for field division is 

1356 
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY, 

1357 
instantiations must refer to Rings.divide rather than the former 

1358 
separate constants, hence infix syntax (_ / _) is usually not available 

1359 
during instantiation.

* New cancellation simprocs for boolean algebras to cancel complementary 

1362 
terms for sup and inf. For example, "sup x (sup y ( x))" simplifies to 

1363 
"top". INCOMPATIBILITY.

* Class uniform_space introduces uniform spaces btw topological spaces 
1366 
and metric spaces. Minor INCOMPATIBILITY: open_<type>_def needs to be 

62205  1367 
introduced in the form of an uniformity. Some constants are more general 
1368 
now, it may be necessary to add type class constraints.
