4
5		[2011-05-23]
6		Added new S-expression library (contributed by Damon Wang)
7
8		[2011-05-17]

13		SML/NJ 110.73
14		-------------------
15
16		[2011-05-12]
17		Modified the implementation of GetOpt.usageInfo so that if the help
18		string has embedded newlines, then the extra lines are properly
19		indented.
20
21		[2011-04-10]
22		Changed the interface of JSONStreamParser to support both parsing files
23		and TextIO.instreams.
24
25		[2011-03-16]
26		Added findExe function to PathUtil module.
27
28		[2010-06-30]
29		Added HTML4 library.
30
31		[2010-03-09]

33
34		--------------------------------------------------------------------------------
35		SML/NJ 110.72
36		-------------------
37
38		[2009-05-13]
39		Added array iterators to DynamicArray module.
40
41		[2009-03-15]
42		Added support for the interval syntax to the AWK RE syntax parser (this
43		syntax was not part of the original version of AWK, but is supported by
44		modern variants and the POSIX standard).
45
46		[2008-10-03]
47		Improved the error messages in the JSON parser.
48
49		[2008-06-11]
50		Added support for begin marks to Thompson engine.
51
52		[2008-05-12]
53		Added parsing support to JSON library.
54
55		[2008-04-18]
56		First commit of JSON Library.  Printing works, but parsing still needs
57		to be implemented.
58
59		[2008-03-18]
60		Committed a major overhaul of the RegExp library.  There is now a new
61		engine that implements Ken Thompson's RE matching algorithm.  The result
62		type of the RE matches has also been simplified by removing an unecessary
63		option type.
64		NOTE: the new RE engine is not complete in that it does not yet support
65		begin/end marks.
66
67		[2007-12-13]
68		Also added list' and listg' which are parameterized over the delimiter-
69		and separator strings used for formatting lists.  (The default for "list" and
70		"listg" is the usual "[" ", " "]".)
71
72		[2007-12-13]
73		Added "elem" function as an inverse to "glue" to FormatComb module.
74		This makes writing extensions possible.  Also added "list" and "option"
75		combinators for formatting list- and option types.
76
77		[2007-11-02]
78		A collection of bug fixes for machine.sml in the Reactive library.
79		(Thanks to Timothy Bourke)
80
81		[2007-05-15]
82		Made the UnixPath.path_list type concrete (= string list).
83
84		[2007-04-24]
85		Added next function to Fifo and Queue modules.
86
87		[2007-02-15]
88		Removed vestigial IntInf and INT_INF definitions.
89
90		[2007-02-14]
91		Changed the representation type of UTF8.wchar from Word32.word to word.
92		Also added the UTF8.maxCodePoint value.
93
94		[2007-01-30]
95		Added the lookup function to the ORD_MAP interface.
96
97		[2007-01-30]
98		Added the fromList function to the ORD_SET interface.  For the red-black
99		tree and list based implementations, this operation is linear for ordered
100		inputs.
101
102		[2007-01-28]
103		Added UTF8 signature and structure.
104
105		[2005-11-07]
106		Internal change: replaced uses of the depreciated Substring.all
107		with the Substring.full
108
109		[2005-11-05]
110		Tweaking of the interval set API.  Added iterators on items and
111		changed the iterators on intervals to have a "Int" suffix.
112		Changed addInterval to addInt, changed list to intervals.  Added
113		the items function.
114
115		[2005-10-31]
116		Fixed a bug in IntervalSetFn().intersect.
117
118		[2005-10-25]
119		Added interval sets to utility library (signatures INTERVAL_DOMAIN
120		and INTERVAL_SET, and functor IntervalSetFn).
121
122		[2005-08-04]
123		Renamed graph-scc.sml to graph-scc-fn.sml.
124
125		[2005-07-23]
126		Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
127		PP_DESC.  Also add nbSpace to PP_DESC signature.
128
129		[2005-07-12]
130		Added ANSITermDev device that uses ANSI terminal display attributes
131		and added a ANSITermPP for pretty printing to such a device.
132
133		[2005-07-06]
134		Added ANSITerm structure, which provides support for ANSI terminal
135		display attributes (e.g., red text).
136
137		[2005-07-06]
138		Refactored the pretty printing library.  The declarative way to
139		construct pretty-printing descriptions now sits on top of the
140		PP_STREAM interface.  Also removed "onNewline" function, which
141		was not implemented.
142
143		[2005-05-05]
144		Added singleton function to MONO_PRIORITYQ interface.
145
146		[2005-05-04]
147		Added the "join" combinator to ParserComb.
148
149		[2005-03-21]
150		Fixed a bug in GetOpt.getOpt.  The argument processing functions
151		for ReqArg and OptArg, and the embedding function for ReturnInOrder
152		were getting applied to all arguments, even past a "--".
153
154		[2005-02-11]
155		Added Atom.same and Atom.lexCompare to the Atom structure.  Eventually,
156		Atom.sameAtom will be removed.
157
158		[2004-12-15]
159		Change HashString.hashString' to hashSubstring.
160
161		[2004-12-09]
162		Added two simple statistics modules:
163		* RealOrderStats implements selection of arbitrary order
164		statistics as well as the median of an array of reals
165		in randomized linear time.
166		* UnivariateStats implements mean, variance, standard and average
167		deviation, skew, kurtosis, and median of a univariate sample
168		(i.e., a set of reals).
169
170		[2004-11-29]
171		Added HashString.hashString' for substrings.
172		Hand-inlined CharVector.fold into HashString for efficiency.
173		Modified atom.sml so that Atom.atom' first tries to find an
174		existing atom before turning its argument into a string. [-blume]
175
176		[2003-09-03]
177		Minor modifications to random.sml due to changes to some
178		Basis interfaces (slices).
179		Significant surgery on bit-array.sml to make it compile with
180		new signature MONO_ARRAY.  This will require further cleanup
181		in the future.
182
183		[2003-08-28]
184		Made compilation of int-inf* conditional.  (The Basis now has
185		a spec-conforming implementation of IntInf, so the one here is
186		no longer needed.)  [-blume]
187
188		[2003-07-31]
189		Added getDevice function to PP_STREAM signature.
190
191		[2003-05-27]
192		Avoid poly-eq in Util/parser-comb.sml.
193
194		[2003-05-22]
195		More cleanup (all in the name of eliminating incomplete matches):
196		- in HTML/html-attrs-fn.sml: fill in missing patterns in two
197		case expressions
198		- in HTML/html-gram: rewrote function groupDefListContents
199		to avoid the (unnecessary) incomplete match
200		- in PP/devices/html-dev.sml: made the implementation of popStyle
201		agree with the comment above it (popStyle on an empty
202		stack is supposed to be a nop)
203		- in PP/src/pp-stream-fn.sml: function setSize: handle case of
204		an empty scanStk
205		- in Util/prime-sizes.sml: raise Fail exceptions instead of
206		Match exceptions when reaching the end of a list
207		(Perhaps this should eventually be rewritten using an on-demand
208		prime-number generator that kicks when needed.)
209
210		[2003-05-22]
211		Cleanup logic in Scan.scanf function.
212
213		[2002-10-03]
214		Fixed bug in formating reals with the %g format.
215
216		[2002-06-18]
217		Fixed a bug in MatchTree.nth (regexp library).  Thanks to
218		Sami Nopanen.
219
220		[2002-05-20]
221		Fixed bug in IntInf module: scanning of hex literals was not
222		handling "0x" prefixes.
223
224		[2002-05-20]
225		Added ControlUtil module and stringControls function.
226
227		[2002-05-17]
228		Added tyName field to ValueSyntax exception in Controls module
229		and path field to registry tree in ControlRegistry module.
230
231		[2002-05-17]
232		Added == and != operators to INT_INF interface.  These are a
233		placeholder until IntInf moves into the SML/NJ compiler.
234
235		[2002-05-16]
236		Added mergeWith function to ORD_MAP interface.
237
238		[2002-05-15]
239		Revised Controls library.
240
241		[2002-04-17]
242		Added Matthias Blume's implementation of Danvey-style format
243		combinators to the Util library.
244
245		[2002-03-14]
246		Merged in Matthias Blume's Controls library.  Warning: the API
247		to this library is likely to change as we get some experience
248		with it.
249
250		[2002-03-11]
251		Added consR1 .. consR5 functions to HashCons library.  These
252		can be used to hash-cons record types.
253
254		[2002-02-21]
255		Fixed infinite loop in LeftPriorityQFn.fromList when given a
256		singleton list as input (Chris Okasaki provided the fix).
257
258		[2002-02-12]
259		Added implementation of priority queues to Util library (using
260		Okasaki's leftist-tree implementation).
261
262		[2001-10-19]
263		Added new HashCons library.
264
265		[2001-10-19]
266		Added PrimeSizes module to Util library.
267
268		[2001-09-27]
269		Fixed bug in UnixEnv module (reported by Leunga).
270
271		[2001-05-05]
272		Added addrToString function to SockUtil module in INet library.
273
274		[2001-05-04]
275		Modified GraphSCC module to support a list of roots (Blume).
276		The old interface still works, but will be dropped when we move
277		to the new Util library.
278
279		[2001-04-06]
280		Added partition function to ORD_SET interface.
281
282		[2001-04-05]
283		Added hasProps function to PropList module.
284
285		[2001-03-16]
286		Minor bug fix in GetOpt: don't pad the help string, since it causes
287		line wraps when one of the help lines is longer than the screen
288		width.  It was also unneccesary.
289
290		[2001-02-23]
291		Added inDomain function to the various kinds of hash tables.
292
293		[2001-02-22]
294		Fixed bug in {Int,Word}RedBlackMapFn.insert (bug 1591).
295
296		[2000-12-13]
297		Added the bit operations to the IntInf module (Leung).
298
299		[2000-11-17]
300		Added where clause to GraphSCCFn result signature (Blume).
301
302		[2000-10-20]
303		Made the result signature of the RegExpFn functor be opaque.
304
305		[2000-09-28]
306		SML/NJ 110.0.7 release.
307
308		[2000-09-02]
309		Added Word versions of hash tables (WordHashTable), finite
310		maps (WordRedBlackMap), and sets (WordRedBlackSet).
311
312		[2000-09-02]
313		fixed bug in Format module (infinity caused infinite loop).
314
315		[2000-07-19]
316		added anchored paths in CM files for NEW_CM.
317
318		[2000-06-30]

320
321		[2000-05-16]
322		Fixed bug in dfa-engine.sml (bug number 1559).
323
324		[2000-05-08]
325		Added setFn to PList.newProp return type.
326
327		[2000-05-05]
328		Added sameHolder function to PropList module.
329
330		[2000-04-05]
331		Fixed a bug in the filter/filteri hash table functions: the number
332		of items in the table was not being recomputed.
333
334		[2000-04-04]
335		Added modify and modifyi iterators to hash tables.
336
337		[2000-03-28]
338		Added anchorLink style to HTMLDev structure in PP/devices.
339
340		[1999-12-03]
341		Added IntHashTable structure to Util library; this structure is
342		a specialization of hash tables to integer keys.
343
344		[1999-12-03]
345		Added default cases to avoid "match not exhaustive" warnings.
346
347		[1999-12-03]
348		Added GraphSCCFn functor to Util library, which implements a
349		strongly-connected components algorithm on directed graphs (written
350		by Matthias Blume).
351
352		[1999-11-10]
353		Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
354		the previous change.
355
356		[1999-11-7]

358
359		[1999-11-1]
360		Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
361
362		[1999-10-20]
363		Fixed bug in RedBlack trees (the linear time construction of
364		trees from ordered sequences was producing backwards trees).
365
366		[1999-10-18]
367		Changed UREF signature so that union, unify, and link operations
368		now return a boolean.
369
370		[1999-10-18]
371		Added peekFn to PropList.newProp return result.
372
373		[1999-10-14]
374		Added TextIOPP structure to pp-lib.cm (it was not being exported).
375
376		[1999-09-21]
377		Changed the getOpt API.  Errors are now reported using a callback
378		and both usage and getOpt take records as arguments.  Also changed
379		the NoArg descriptor to take a function so that imperative argument
380		processing can be supported.
381
382		[1999-09-20]
383		Changed CM files to be compatible with both the old (110.0.x) and
384		new (110.20+) versions of CM.
385
386		[1999-09-17]
387		Added PropList:PROP_LIST structure.  This structure implements
388		property lists using Stephen Weeks's technique.
389
390		[1999-09-17]
391		Improved the red-black tree implementations with linear-time union,
392		intersection, difference, and filter operations.  Also reimplemented
393		the delete function in a way that does not require an extra constructor.
394
395		[1999-09-09]
396		Added Red-Black-Tree implementation of sets and maps.  Two new
397		functors (RedBlackMapFn and RedBlackSetFn) and four new structures
398		(IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
399		Also added aliases AtomMap and AtomSet that for the RB implementations.
400
401		[1999-09-03]
402		Added missing support for WORD and WORD8 format items to Format structure.
403		Still need to handle LWORD items!!
404
405		[1999-08-17]
406		Added DynamicArray:DYNAMIC_ARRAY structure.
407
408	[1999-07-06]	[1999-07-06]
