3    --------------------------------------------------------------------------------
4    
5    [2011-04-17]
6            Fixed bug in JSON scanner.  It didn't handle escaped backslash or double
7            quote correctly.
8    
9    [2011-04-12]
10            Modified the implementation of GetOpt.usageInfo so that if the help
11            string has embedded newlines, then the extra lines are properly
12            indented.
13    
14    [2011-04-10]
15            Changed the interface of JSONStreamParser to support both parsing files
16            and TextIO.instreams.
17    
18    [2011-03-16]
19            Added findExe function to PathUtil module.
20    
21    [2010-06-30]
22            Added HTML4 library.
23    
24    [2010-03-09]
25            Fixed bug in hashed cons library (bug #55).
26    
27    [2009-05-13]
28            Added array iterators to DynamicArray module.
29    
30    [2009-03-15]
31            Added support for the interval syntax to the AWK RE syntax parser (this
32            syntax was not part of the original version of AWK, but is supported by
33            modern variants and the POSIX standard).
34    
35    [2008-10-03]
36            Improved the error messages in the JSON parser.
37    
38    [2008-06-11]
39            Added support for begin marks to Thompson engine.
40    
41    [2008-05-12]
42            Added parsing support to JSON library.
43    
44    [2008-04-18]
45            First commit of JSON Library.  Printing works, but parsing still needs
46            to be implemented.
47    
48    [2008-03-18]
49            Committed a major overhaul of the RegExp library.  There is now a new
50            engine that implements Ken Thompson's RE matching algorithm.  The result
51            type of the RE matches has also been simplified by removing an unecessary
52            option type.
53            NOTE: the new RE engine is not complete in that it does not yet support
54            begin/end marks.
55    
56    [2007-12-13]
57            Also added list' and listg' which are parameterized over the delimiter-
58            and separator strings used for formatting lists.  (The default for "list" and
59            "listg" is the usual "[" ", " "]".)
60    
61    [2007-12-13]
62            Added "elem" function as an inverse to "glue" to FormatComb module.
63            This makes writing extensions possible.  Also added "list" and "option"
64            combinators for formatting list- and option types.
65    
66    [2007-11-02]
67            A collection of bug fixes for machine.sml in the Reactive library.
68            (Thanks to Timothy Bourke)
69    
70    [2007-05-15]
71            Made the UnixPath.path_list type concrete (= string list).
72    
73    [2007-04-24]
74            Added next function to Fifo and Queue modules.
75    
76    [2007-02-15]
77            Removed vestigial IntInf and INT_INF definitions.
78    
79    [2007-02-14]
80            Changed the representation type of UTF8.wchar from Word32.word to word.
81            Also added the UTF8.maxCodePoint value.
82    
83    [2007-01-30]
84            Added the lookup function to the ORD_MAP interface.
85    
86    [2007-01-30]
87            Added the fromList function to the ORD_SET interface.  For the red-black
88            tree and list based implementations, this operation is linear for ordered
89            inputs.
90    
91    [2007-01-28]
92            Added UTF8 signature and structure.
93    
94    [2005-11-07]
95            Internal change: replaced uses of the depreciated Substring.all
96            with the Substring.full
97    
98    [2005-11-05]
99            Tweaking of the interval set API.  Added iterators on items and
100            changed the iterators on intervals to have a "Int" suffix.
101            Changed addInterval to addInt, changed list to intervals.  Added
102            the items function.
103    
104    [2005-10-31]
105            Fixed a bug in IntervalSetFn().intersect.
106    
107    [2005-10-25]
108            Added interval sets to utility library (signatures INTERVAL_DOMAIN
109            and INTERVAL_SET, and functor IntervalSetFn).
110    
111    [2005-08-04]
112            Renamed graph-scc.sml to graph-scc-fn.sml.
113    
114    [2005-07-23]
115            Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
116            PP_DESC.  Also add nbSpace to PP_DESC signature.
117    
118    [2005-07-12]
119            Added ANSITermDev device that uses ANSI terminal display attributes
120            and added a ANSITermPP for pretty printing to such a device.
121    
122    [2005-07-06]
123            Added ANSITerm structure, which provides support for ANSI terminal
124            display attributes (e.g., red text).
125    
126    [2005-07-06]
127            Refactored the pretty printing library.  The declarative way to
128            construct pretty-printing descriptions now sits on top of the
129            PP_STREAM interface.  Also removed "onNewline" function, which
130            was not implemented.
131    
132    [2005-05-05]
133            Added singleton function to MONO_PRIORITYQ interface.
134    
135    [2005-05-04]
136            Added the "join" combinator to ParserComb.
137    
138    [2005-03-21]
139            Fixed a bug in GetOpt.getOpt.  The argument processing functions
140            for ReqArg and OptArg, and the embedding function for ReturnInOrder
141            were getting applied to all arguments, even past a "--".
142    
143    [2005-02-11]
144            Added Atom.same and Atom.lexCompare to the Atom structure.  Eventually,
145            Atom.sameAtom will be removed.
146    
147    [2004-12-15]
148            Change HashString.hashString' to hashSubstring.
149    
150    [2004-12-09]
151            Added two simple statistics modules:
152            * RealOrderStats implements selection of arbitrary order
153              statistics as well as the median of an array of reals
154              in randomized linear time.
155            * UnivariateStats implements mean, variance, standard and average
156              deviation, skew, kurtosis, and median of a univariate sample
157              (i.e., a set of reals).
158    
159    [2004-11-29]
160            Added HashString.hashString' for substrings.
161            Hand-inlined CharVector.fold into HashString for efficiency.
162            Modified atom.sml so that Atom.atom' first tries to find an
163            existing atom before turning its argument into a string. [-blume]
164    
165    [2003-09-03]
166            Minor modifications to random.sml due to changes to some
167            Basis interfaces (slices).
168            Significant surgery on bit-array.sml to make it compile with
169            new signature MONO_ARRAY.  This will require further cleanup
170            in the future.
171    
172    [2003-08-28]
173            Made compilation of int-inf* conditional.  (The Basis now has
174            a spec-conforming implementation of IntInf, so the one here is
175            no longer needed.)  [-blume]
176    
177    [2003-07-31]
178            Added getDevice function to PP_STREAM signature.
179    
180    [2003-05-27]
181            Avoid poly-eq in Util/parser-comb.sml.
182    
183    [2003-05-22]
184            More cleanup (all in the name of eliminating incomplete matches):
185              - in HTML/html-attrs-fn.sml: fill in missing patterns in two
186                case expressions
187              - in HTML/html-gram: rewrote function groupDefListContents
188                to avoid the (unnecessary) incomplete match
189              - in PP/devices/html-dev.sml: made the implementation of popStyle
190                agree with the comment above it (popStyle on an empty
191                stack is supposed to be a nop)
192              - in PP/src/pp-stream-fn.sml: function setSize: handle case of
193                an empty scanStk
194              - in Util/prime-sizes.sml: raise Fail exceptions instead of
195                Match exceptions when reaching the end of a list
196                (Perhaps this should eventually be rewritten using an on-demand
197                 prime-number generator that kicks when needed.)
198    
199    [2003-05-22]
200            Cleanup logic in Scan.scanf function.
201    
202    [2002-10-03]
203            Fixed bug in formating reals with the %g format.
204    
205    [2002-06-18]
206            Fixed a bug in MatchTree.nth (regexp library).  Thanks to
207            Sami Nopanen.
208    
209    [2002-05-20]
210            Fixed bug in IntInf module: scanning of hex literals was not
211            handling "0x" prefixes.
212    
213    [2002-05-20]
214            Added ControlUtil module and stringControls function.
215    
216    [2002-05-17]
217            Added tyName field to ValueSyntax exception in Controls module
218            and path field to registry tree in ControlRegistry module.
219    
220    [2002-05-17]
221            Added == and != operators to INT_INF interface.  These are a
222            placeholder until IntInf moves into the SML/NJ compiler.
223    
224    [2002-05-16]
225            Added mergeWith function to ORD_MAP interface.
226    
227    [2002-05-15]
228            Revised Controls library.
229    
230    [2002-04-17]
231            Added Matthias Blume's implementation of Danvey-style format
232            combinators to the Util library.
233    
234    [2002-03-14]
235            Merged in Matthias Blume's Controls library.  Warning: the API
236            to this library is likely to change as we get some experience
237            with it.
238    
239    [2002-03-11]
240            Added consR1 .. consR5 functions to HashCons library.  These
241            can be used to hash-cons record types.
242    
243    [2002-02-21]
244            Fixed infinite loop in LeftPriorityQFn.fromList when given a
245            singleton list as input (Chris Okasaki provided the fix).
246    
247    [2002-02-12]
248            Added implementation of priority queues to Util library (using
249            Okasaki's leftist-tree implementation).
250    
251    [2001-10-19]
252            Added new HashCons library.
253    
254    [2001-10-19]
255            Added PrimeSizes module to Util library.
256    
257    [2001-09-27]
258            Fixed bug in UnixEnv module (reported by Leunga).
259    
260    [2001-05-05]
261            Added addrToString function to SockUtil module in INet library.
262    
263    [2001-05-04]
264            Modified GraphSCC module to support a list of roots (Blume).
265            The old interface still works, but will be dropped when we move
266            to the new Util library.
267    
268    [2001-04-06]
269            Added partition function to ORD_SET interface.
270    
271    [2001-04-05]
272            Added hasProps function to PropList module.
273    
274    [2001-03-16]
275            Minor bug fix in GetOpt: don't pad the help string, since it causes
276            line wraps when one of the help lines is longer than the screen
277            width.  It was also unneccesary.
278    
279    [2001-02-23]
280            Added inDomain function to the various kinds of hash tables.
281    
282    [2001-02-22]
283            Fixed bug in {Int,Word}RedBlackMapFn.insert (bug 1591).
284    
285    [2000-12-13]
286            Added the bit operations to the IntInf module (Leung).
287    
288    [2000-11-17]
289            Added where clause to GraphSCCFn result signature (Blume).
290    
291    [2000-10-20]
292            Made the result signature of the RegExpFn functor be opaque.
293    
294    [2000-09-28]
295            SML/NJ 110.0.7 release.
296    
297    [2000-09-02]
298            Added Word versions of hash tables (WordHashTable), finite
299            maps (WordRedBlackMap), and sets (WordRedBlackSet).
300    
301    [2000-09-02]
302            fixed bug in Format module (infinity caused infinite loop).
303    
304    [2000-07-19]
305            added anchored paths in CM files for NEW_CM.
306    
307    [2000-06-30]
308            added implementation of LWORD in Format module.
309    
310    [2000-05-16]
311            Fixed bug in dfa-engine.sml (bug number 1559).
312    
313    [2000-05-08]
314            Added setFn to PList.newProp return type.
315    
316    [2000-05-05]
317            Added sameHolder function to PropList module.
318    
319    [2000-04-05]
320            Fixed a bug in the filter/filteri hash table functions: the number
321            of items in the table was not being recomputed.
322    
323    [2000-04-04]
324            Added modify and modifyi iterators to hash tables.
325    
326    [2000-03-28]
327            Added anchorLink style to HTMLDev structure in PP/devices.
328    
329    [1999-12-03]
330            Added IntHashTable structure to Util library; this structure is
331            a specialization of hash tables to integer keys.
332    
333    [1999-12-03]
334            Added default cases to avoid "match not exhaustive" warnings.
335    
336    [1999-12-03]
337            Added GraphSCCFn functor to Util library, which implements a
338            strongly-connected components algorithm on directed graphs (written
339            by Matthias Blume).
340    
341    [1999-11-10]
342            Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
343            the previous change.
344    
345    [1999-11-7]
346            Made the result signatures of ListSetFn and ListMapFn opaque.
347    
348    [1999-11-1]
349            Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
350    
351    [1999-10-20]
352            Fixed bug in RedBlack trees (the linear time construction of
353            trees from ordered sequences was producing backwards trees).
354    
355    [1999-10-18]
356            Changed UREF signature so that union, unify, and link operations
357            now return a boolean.
358    
359    [1999-10-18]
360            Added peekFn to PropList.newProp return result.
361    
362    [1999-10-14]
363            Added TextIOPP structure to pp-lib.cm (it was not being exported).
364    
365    [1999-09-21]
366            Changed the getOpt API.  Errors are now reported using a callback
367            and both usage and getOpt take records as arguments.  Also changed
368            the NoArg descriptor to take a function so that imperative argument
369            processing can be supported.
370    
371    [1999-09-20]
372            Changed CM files to be compatible with both the old (110.0.x) and
373            new (110.20+) versions of CM.
374    
375    [1999-09-17]
376            Added PropList:PROP_LIST structure.  This structure implements
377            property lists using Stephen Weeks's technique.
378    
379    [1999-09-17]
380            Improved the red-black tree implementations with linear-time union,
381            intersection, difference, and filter operations.  Also reimplemented
382            the delete function in a way that does not require an extra constructor.
383    
384    [1999-09-09]
385            Added Red-Black-Tree implementation of sets and maps.  Two new
386            functors (RedBlackMapFn and RedBlackSetFn) and four new structures
387            (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
388            Also added aliases AtomMap and AtomSet that for the RB implementations.
389    
390    [1999-09-03]
391            Added missing support for WORD and WORD8 format items to Format structure.
392            Still need to handle LWORD items!!
393    
394    [1999-08-17]
395            Added DynamicArray:DYNAMIC_ARRAY structure.
396    
397    [1999-07-06]
398            Added declarative representation of pretty-printing to PPStreamFn.
399            This replaces the PPDescFn and PP_DESC components (which were not
400            implemented anyway).
401    
402    [1999-07-02]
403            Moved SockUtil structure into a new INet library.  Also split out the
404            Unix-specific socket operations into a UnixSockUtil module.  (Sockets
405            are now supported on Win32).
406    
407    [1999-06-17]
408            Added listKeys function to ORD_MAP API.
409    
410    [1999-06-14]
411            Added Riccardo Pucella's GetOpt structure to Util library.
412    
413    [1999-06-14]
414            Added singleton and inDomain functions to ORD_MAP API.
415    
416    [1999-06-02]
417            Merged in some bug fixes from the compiler's version of the IntInf
418            structure.
419    
420    [1999-05-05]
421            Fixed a couple of bugs in the PP library having to do with nesting
422            absolute and relative indentations.
423    
424    [1999-04-21]
425            Added a way to pass control information to a PP device via the PP
426            stream (function control in PP_STREAM).
427    
428    [1999-04-16]
429            Added better style support to the HTML PP device.
