3		--------------------------------------------------------------------------------
4
5		[2005-08-04]
6		Renamed graph-scc.sml to graph-scc-fn.sml.
7
8		[2005-07-23]
9		Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
10		PP_DESC.  Also add nbSpace to PP_DESC signature.
11
12		[2005-07-12]
13		Added ANSITermDev device that uses ANSI terminal display attributes
14		and added a ANSITermPP for pretty printing to such a device.
15
16		[2005-07-06]
17		Added ANSITerm structure, which provides support for ANSI terminal
18		display attributes (e.g., red text).
19
20		[2005-07-06]
21		Refactored the pretty printing library.  The declarative way to
22		construct pretty-printing descriptions now sits on top of the
23		PP_STREAM interface.  Also removed "onNewline" function, which
24		was not implemented.
25
26		[2005-05-05]
27		Added singleton function to MONO_PRIORITYQ interface.
28
29		[2005-05-04]
30		Added the "join" combinator to ParserComb.
31
32		[2005-03-21]
33		Fixed a bug in GetOpt.getOpt.  The argument processing functions
34		for ReqArg and OptArg, and the embedding function for ReturnInOrder
35		were getting applied to all arguments, even past a "--".
36
37		[2005-02-11]
38		Added Atom.same and Atom.lexCompare to the Atom structure.  Eventually,
39		Atom.sameAtom will be removed.
40
41		[2004-12-15]
42		Change HashString.hashString' to hashSubstring.
43
44		[2004-12-09]
45		Added two simple statistics modules:
46		* RealOrderStats implements selection of arbitrary order
47		statistics as well as the median of an array of reals
48		in randomized linear time.
49		* UnivariateStats implements mean, variance, standard and average
50		deviation, skew, kurtosis, and median of a univariate sample
51		(i.e., a set of reals).
52
53		[2004-11-29]
54		Added HashString.hashString' for substrings.
55		Hand-inlined CharVector.fold into HashString for efficiency.
56		Modified atom.sml so that Atom.atom' first tries to find an
57		existing atom before turning its argument into a string. [-blume]
58
59		[2003-09-03]
60		Minor modifications to random.sml due to changes to some
61		Basis interfaces (slices).
62		Significant surgery on bit-array.sml to make it compile with
63		new signature MONO_ARRAY.  This will require further cleanup
64		in the future.
65
66		[2003-08-28]
67		Made compilation of int-inf* conditional.  (The Basis now has
68		a spec-conforming implementation of IntInf, so the one here is
69		no longer needed.)  [-blume]
70
71		[2003-07-31]
72		Added getDevice function to PP_STREAM signature.
73
74		[2003-05-27]
75		Avoid poly-eq in Util/parser-comb.sml.
76
77		[2003-05-22]
78		More cleanup (all in the name of eliminating incomplete matches):
79		- in HTML/html-attrs-fn.sml: fill in missing patterns in two
80		case expressions
81		- in HTML/html-gram: rewrote function groupDefListContents
82		to avoid the (unnecessary) incomplete match
83		- in PP/devices/html-dev.sml: made the implementation of popStyle
84		agree with the comment above it (popStyle on an empty
85		stack is supposed to be a nop)
86		- in PP/src/pp-stream-fn.sml: function setSize: handle case of
87		an empty scanStk
88		- in Util/prime-sizes.sml: raise Fail exceptions instead of
89		Match exceptions when reaching the end of a list
90		(Perhaps this should eventually be rewritten using an on-demand
91		prime-number generator that kicks when needed.)
92
93		[2003-05-22]
94		Cleanup logic in Scan.scanf function.
95
96		[2002-10-03]
97		Fixed bug in formating reals with the %g format.
98
99		[2002-06-18]
100		Fixed a bug in MatchTree.nth (regexp library).  Thanks to
101		Sami Nopanen.
102
103		[2002-05-20]
104		Fixed bug in IntInf module: scanning of hex literals was not
105		handling "0x" prefixes.
106
107		[2002-05-20]
108		Added ControlUtil module and stringControls function.
109
110		[2002-05-17]
111		Added tyName field to ValueSyntax exception in Controls module
112		and path field to registry tree in ControlRegistry module.
113
114		[2002-05-17]
115		Added == and != operators to INT_INF interface.  These are a
116		placeholder until IntInf moves into the SML/NJ compiler.
117
118		[2002-05-16]
119		Added mergeWith function to ORD_MAP interface.
120
121		[2002-05-15]
122		Revised Controls library.
123
124		[2002-04-17]
125		Added Matthias Blume's implementation of Danvey-style format
126		combinators to the Util library.
127
128		[2002-03-14]
129		Merged in Matthias Blume's Controls library.  Warning: the API
130		to this library is likely to change as we get some experience
131		with it.
132
133		[2002-03-11]
134		Added consR1 .. consR5 functions to HashCons library.  These
135		can be used to hash-cons record types.
136
137		[2002-02-21]
138		Fixed infinite loop in LeftPriorityQFn.fromList when given a
139		singleton list as input (Chris Okasaki provided the fix).
140
141		[2002-02-12]
142		Added implementation of priority queues to Util library (using
143		Okasaki's leftist-tree implementation).
144
145		[2001-10-19]
146		Added new HashCons library.
147
148		[2001-10-19]
149		Added PrimeSizes module to Util library.
150
151		[2001-09-27]
152		Fixed bug in UnixEnv module (reported by Leunga).
153
154		[2001-05-05]
155		Added addrToString function to SockUtil module in INet library.
156
157		[2001-05-04]
158		Modified GraphSCC module to support a list of roots (Blume).
159		The old interface still works, but will be dropped when we move
160		to the new Util library.
161
162		[2001-04-06]
163		Added partition function to ORD_SET interface.
164
165		[2001-04-05]
166		Added hasProps function to PropList module.
167
168		[2001-03-16]
169		Minor bug fix in GetOpt: don't pad the help string, since it causes
170		line wraps when one of the help lines is longer than the screen
171		width.  It was also unneccesary.
172
173		[2001-02-23]
174		Added inDomain function to the various kinds of hash tables.
175
176		[2001-02-22]
177		Fixed bug in {Int,Word}RedBlackMapFn.insert (bug 1591).
178
179		[2000-12-13]
180		Added the bit operations to the IntInf module (Leung).
181
182		[2000-11-17]
183		Added where clause to GraphSCCFn result signature (Blume).
184
185		[2000-10-20]
186		Made the result signature of the RegExpFn functor be opaque.
187
188		[2000-09-28]
189		SML/NJ 110.0.7 release.
190
191		[2000-09-02]
192		Added Word versions of hash tables (WordHashTable), finite
193		maps (WordRedBlackMap), and sets (WordRedBlackSet).
194
195		[2000-09-02]
196		fixed bug in Format module (infinity caused infinite loop).
197
198		[2000-07-19]
199		added anchored paths in CM files for NEW_CM.
200
201		[2000-06-30]

206
207		[2000-05-08]
208		Added setFn to PList.newProp return type.
209
210		[2000-05-05]
211		Added sameHolder function to PropList module.
212
213		[2000-04-05]
214		Fixed a bug in the filter/filteri hash table functions: the number
215		of items in the table was not being recomputed.
216
217		[2000-04-04]
218		Added modify and modifyi iterators to hash tables.
219
220		[2000-03-28]
221		Added anchorLink style to HTMLDev structure in PP/devices.
222
223		[1999-12-03]
224		Added IntHashTable structure to Util library; this structure is
225		a specialization of hash tables to integer keys.
226
227		[1999-12-03]
228		Added default cases to avoid "match not exhaustive" warnings.
229
230		[1999-12-03]
231		Added GraphSCCFn functor to Util library, which implements a
232		strongly-connected components algorithm on directed graphs (written
233		by Matthias Blume).
234
235		[1999-11-10]
236		Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
237		the previous change.
238
239		[1999-11-7]
240		Made the result signatures of ListSetFn and ListMapFn opaque.
241
242		[1999-11-1]
243		Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
244
245		[1999-10-20]
246		Fixed bug in RedBlack trees (the linear time construction of
247		trees from ordered sequences was producing backwards trees).
248
249		[1999-10-18]
250		Changed UREF signature so that union, unify, and link operations
251		now return a boolean.
252
253		[1999-10-18]
254		Added peekFn to PropList.newProp return result.
255
256		[1999-10-14]
257		Added TextIOPP structure to pp-lib.cm (it was not being exported).
258
259		[1999-09-21]
260		Changed the getOpt API.  Errors are now reported using a callback
261		and both usage and getOpt take records as arguments.  Also changed
262		the NoArg descriptor to take a function so that imperative argument
263		processing can be supported.
264
265		[1999-09-20]
266		Changed CM files to be compatible with both the old (110.0.x) and
267		new (110.20+) versions of CM.
268
269		[1999-09-17]
270		Added PropList:PROP_LIST structure.  This structure implements
271		property lists using Stephen Weeks's technique.
272
273		[1999-09-17]
274		Improved the red-black tree implementations with linear-time union,
275		intersection, difference, and filter operations.  Also reimplemented
276		the delete function in a way that does not require an extra constructor.
277
278		[1999-09-09]
279		Added Red-Black-Tree implementation of sets and maps.  Two new
280		functors (RedBlackMapFn and RedBlackSetFn) and four new structures
281		(IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
282		Also added aliases AtomMap and AtomSet that for the RB implementations.
283
284		[1999-09-03]
285		Added missing support for WORD and WORD8 format items to Format structure.
286		Still need to handle LWORD items!!
287
288		[1999-08-17]
289		Added DynamicArray:DYNAMIC_ARRAY structure.
290
291		[1999-07-06]
292		Added declarative representation of pretty-printing to PPStreamFn.
293		This replaces the PPDescFn and PP_DESC components (which were not
294		implemented anyway).
295
296		[1999-07-02]
297		Moved SockUtil structure into a new INet library.  Also split out the
298		Unix-specific socket operations into a UnixSockUtil module.  (Sockets
299		are now supported on Win32).
300
301		[1999-06-17]
302		Added listKeys function to ORD_MAP API.
303
304		[1999-06-14]
305		Added Riccardo Pucella's GetOpt structure to Util library.
306
307		[1999-06-14]
308		Added singleton and inDomain functions to ORD_MAP API.
309
310		[1999-06-02]
311		Merged in some bug fixes from the compiler's version of the IntInf
312		structure.
313
314		[1999-05-05]
315		Fixed a couple of bugs in the PP library having to do with nesting
316		absolute and relative indentations.
317
318		[1999-04-21]
319		Added a way to pass control information to a PP device via the PP
320		stream (function control in PP_STREAM).
321
322		[1999-04-16]
323		Added better style support to the HTML PP device.
324
325		[1998-09-04]
326		Added isEmpty predicate and first fucntion to ORD_MAP
327		signature (and to implementations).
328
329		[1998-06-23]
330		Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
