Revision 3894 - (view) (download)

1 : monnier 2 This is a list of changes to the SML/NJ Library; the version numbers
2 :     correspond to SML/NJ releases.
3 : jhr 3815
4 : jhr 3894 [2014-07-15]
5 :     Reimplementation of delete/remove operations in red-black-tree
6 :     versions of sets and maps. The previous implementation could
7 :     result in violations of the data-structure invariants, which
8 :     was leading to unbalanced trees and loss of performance. Note
9 :     that the order invariants were correctly maintained, so correctness
10 :     of the operations was not an issue.
11 :    
12 : jhr 3873 [2014-03-27]
13 :     Added XML library, which is a lightweight library for parsing XML
14 :     files. The library does not support validation and will immediatly
15 :     raise an exception on syntax errors. Its purpose is to ease the
16 :     writing of applications that must process data files that are
17 :     in XML syntax.
18 :    
19 : jhr 3860 [2013-11-20]
20 :     Changes to S-expression parsing library. Allow multiple top-level
21 :     values in a file (parsing now returns a list). Handle LISP/Scheme-style
22 :     comments ("; ...").
23 :    
24 : jhr 1340 --------------------------------------------------------------------------------
25 : jhr 3815 SML/NJ 110.76
26 :     -------------------
27 :    
28 : jhr 3796 [2012-10-30]
29 :     Fixed bug in DynamicArray iterators because of bad slice dimensions
30 :     (bug #108). Also switched to using Array.fromList to implement fromList
31 :     function.
32 : jhr 1732
33 : jhr 3796 --------------------------------------------------------------------------------
34 :     SML/NJ 110.75

39 :     base64 strings.
40 :    
41 : jhr 3759 [2012-09-23]
42 :     Added exists, existsi, all, and alli functions to ORD_MAP signature and
43 :     implementations.
44 :    
45 :     [2012-09-23]
46 :     Added all function to ORD_SET signature and implementations.
47 :    
48 : jhr 3717 [2012-03-26]
49 :     Added subtract, subtract', and subtractList functions to ORD_SET
50 :     interface and implementations.
51 :    
52 : jhr 3710 [2012-03-09]
53 :     Modified PathUtil module to handle the case where the filename is an

55 :    
56 :     --------------------------------------------------------------------------------
57 : jhr 3711 SML/NJ 110.74
58 : jhr 3710 -------------------
59 :    
60 : jhr 3639 [2011-11-25]
61 :     Added hash-table-based implementation of sets (HASH_SET signature and
62 :     HashSetFn functor).
63 :    
64 : jhr 3635 [2011-05-23]
65 :     Added new S-expression library (contributed by Damon Wang)
66 :    
67 :     [2011-05-17]
68 : jhr 3632 Fixed bug in JSON scanner. It didn't handle escaped backslash or double
69 :     quote correctly.
70 :    
71 : jhr 3635 --------------------------------------------------------------------------------
72 :     SML/NJ 110.73
73 :     -------------------
74 :    
75 :     [2011-05-12]
76 : jhr 3596 Modified the implementation of GetOpt.usageInfo so that if the help
77 :     string has embedded newlines, then the extra lines are properly
78 :     indented.
79 :    
80 : jhr 3590 [2011-04-10]
81 :     Changed the interface of JSONStreamParser to support both parsing files

92 : jhr 3517
93 : jhr 3635 --------------------------------------------------------------------------------
94 :     SML/NJ 110.72
95 :     -------------------
96 :    
97 : jhr 3337 [2009-05-13]
98 :     Added array iterators to DynamicArray module.
99 :    
100 : jhr 3279 [2009-03-15]
101 :     Added support for the interval syntax to the AWK RE syntax parser (this
102 :     syntax was not part of the original version of AWK, but is supported by
103 :     modern variants and the POSIX standard).
104 :    
105 : jhr 3236 [2008-10-03]
106 :     Improved the error messages in the JSON parser.
107 :    
108 : jhr 3194 [2008-06-11]
109 :     Added support for begin marks to Thompson engine.
110 :    
111 :     [2008-05-12]
112 :     Added parsing support to JSON library.
113 :    
114 : jhr 2996 [2008-04-18]
115 :     First commit of JSON Library. Printing works, but parsing still needs
116 :     to be implemented.
117 :    
118 : jhr 2958 [2008-03-18]
119 :     Committed a major overhaul of the RegExp library. There is now a new
120 :     engine that implements Ken Thompson's RE matching algorithm. The result
121 :     type of the RE matches has also been simplified by removing an unecessary
122 :     option type.
123 :     NOTE: the new RE engine is not complete in that it does not yet support
124 :     begin/end marks.
125 :    
126 : blume 2918 [2007-12-13]
127 : blume 2919 Also added list' and listg' which are parameterized over the delimiter-
128 :     and separator strings used for formatting lists. (The default for "list" and
129 : jhr 2935 "listg" is the usual "[" ", " "]".)
130 : blume 2919
131 :     [2007-12-13]
132 : blume 2918 Added "elem" function as an inverse to "glue" to FormatComb module.
133 :     This makes writing extensions possible. Also added "list" and "option"
134 :     combinators for formatting list- and option types.
135 :    
136 : jhr 2832 [2007-11-02]
137 : jhr 2830 A collection of bug fixes for machine.sml in the Reactive library.
138 :     (Thanks to Timothy Bourke)
139 :    
140 : jhr 2547 [2007-05-15]
141 :     Made the UnixPath.path_list type concrete (= string list).
142 :    
143 : jhr 2449 [2007-04-24]
144 :     Added next function to Fifo and Queue modules.
145 :    
146 : jhr 2337 [2007-02-15]
147 :     Removed vestigial IntInf and INT_INF definitions.
148 :    
149 : jhr 2332 [2007-02-14]
150 :     Changed the representation type of UTF8.wchar from Word32.word to word.
151 :     Also added the UTF8.maxCodePoint value.
152 :    
153 : jhr 2272 [2007-01-30]
154 : jhr 2274 Added the lookup function to the ORD_MAP interface.
155 :    
156 :     [2007-01-30]
157 : jhr 2272 Added the fromList function to the ORD_SET interface. For the red-black
158 :     tree and list based implementations, this operation is linear for ordered
159 :     inputs.
160 :    
161 : jhr 2270 [2007-01-28]
162 :     Added UTF8 signature and structure.
163 :    
164 : jhr 1861 [2005-11-07]
165 :     Internal change: replaced uses of the depreciated Substring.all
166 :     with the Substring.full
167 :    
168 : jhr 1857 [2005-11-05]
169 :     Tweaking of the interval set API. Added iterators on items and
170 :     changed the iterators on intervals to have a "Int" suffix.
171 :     Changed addInterval to addInt, changed list to intervals. Added
172 :     the items function.
173 :    
174 : jhr 1853 [2005-10-31]
175 :     Fixed a bug in IntervalSetFn().intersect.
176 :    
177 : jhr 1840 [2005-10-25]
178 :     Added interval sets to utility library (signatures INTERVAL_DOMAIN
179 :     and INTERVAL_SET, and functor IntervalSetFn).
180 :    
181 : jhr 1833 [2005-08-04]
182 :     Renamed graph-scc.sml to graph-scc-fn.sml.
183 :    
184 : jhr 1830 [2005-07-23]
185 :     Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
186 :     PP_DESC. Also add nbSpace to PP_DESC signature.
187 :    
188 : jhr 1816 [2005-07-12]
189 :     Added ANSITermDev device that uses ANSI terminal display attributes
190 :     and added a ANSITermPP for pretty printing to such a device.
191 :    
192 : jhr 1809 [2005-07-06]
193 : jhr 1810 Added ANSITerm structure, which provides support for ANSI terminal
194 :     display attributes (e.g., red text).
195 :    
196 :     [2005-07-06]
197 : jhr 1809 Refactored the pretty printing library. The declarative way to
198 :     construct pretty-printing descriptions now sits on top of the
199 :     PP_STREAM interface. Also removed "onNewline" function, which
200 :     was not implemented.
201 :    
202 : jhr 1788 [2005-05-05]
203 :     Added singleton function to MONO_PRIORITYQ interface.
204 :    
205 : mblume 1783 [2005-05-04]
206 :     Added the "join" combinator to ParserComb.
207 :    
208 : jhr 1772 [2005-03-21]
209 :     Fixed a bug in GetOpt.getOpt. The argument processing functions
210 :     for ReqArg and OptArg, and the embedding function for ReturnInOrder
211 :     were getting applied to all arguments, even past a "--".
212 :    
213 : jhr 1756 [2005-02-11]
214 :     Added Atom.same and Atom.lexCompare to the Atom structure. Eventually,
215 :     Atom.sameAtom will be removed.
216 :    
217 : jhr 1732 [2004-12-15]
218 :     Change HashString.hashString' to hashSubstring.
219 :    
220 : mblume 1720 [2004-12-09]
221 :     Added two simple statistics modules:
222 :     * RealOrderStats implements selection of arbitrary order
223 :     statistics as well as the median of an array of reals
224 :     in randomized linear time.
225 :     * UnivariateStats implements mean, variance, standard and average
226 :     deviation, skew, kurtosis, and median of a univariate sample
227 :     (i.e., a set of reals).
228 :    
229 : mblume 1718 [2004-11-29]
230 :     Added HashString.hashString' for substrings.
231 :     Hand-inlined CharVector.fold into HashString for efficiency.
232 :     Modified atom.sml so that Atom.atom' first tries to find an
233 :     existing atom before turning its argument into a string. [-blume]
234 :    
235 : mblume 1350 [2003-09-03]
236 :     Minor modifications to random.sml due to changes to some
237 :     Basis interfaces (slices).
238 :     Significant surgery on bit-array.sml to make it compile with
239 :     new signature MONO_ARRAY. This will require further cleanup
240 :     in the future.
241 : monnier 2
242 : mblume 1350 [2003-08-28]
243 :     Made compilation of int-inf* conditional. (The Basis now has
244 :     a spec-conforming implementation of IntInf, so the one here is
245 :     no longer needed.) [-blume]
246 :    
247 : jhr 1340 [2003-07-31]
248 :     Added getDevice function to PP_STREAM signature.
249 :    
250 : mblume 1335 [2003-05-27]
251 :     Avoid poly-eq in Util/parser-comb.sml.
252 :    
253 : mblume 1334 [2003-05-22]
254 :     More cleanup (all in the name of eliminating incomplete matches):
255 :     - in HTML/html-attrs-fn.sml: fill in missing patterns in two
256 :     case expressions
257 :     - in HTML/html-gram: rewrote function groupDefListContents
258 :     to avoid the (unnecessary) incomplete match
259 :     - in PP/devices/html-dev.sml: made the implementation of popStyle
260 :     agree with the comment above it (popStyle on an empty
261 :     stack is supposed to be a nop)
262 : jhr 1340 - in PP/src/pp-stream-fn.sml: function setSize: handle case of
263 :     an empty scanStk
264 : mblume 1334 - in Util/prime-sizes.sml: raise Fail exceptions instead of
265 :     Match exceptions when reaching the end of a list
266 :     (Perhaps this should eventually be rewritten using an on-demand
267 :     prime-number generator that kicks when needed.)
268 : jhr 751
269 : jhr 1333 [2003-05-22]
270 :     Cleanup logic in Scan.scanf function.
271 :    
272 : jhr 1268 [2002-10-03]
273 :     Fixed bug in formating reals with the %g format.
274 :    
275 : jhr 1248 [2002-06-18]
276 :     Fixed a bug in MatchTree.nth (regexp library). Thanks to
277 :     Sami Nopanen.
278 :    
279 : jhr 1206 [2002-05-20]
280 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
281 :     handling "0x" prefixes.
282 :    
283 :     [2002-05-20]
284 : jhr 1206 Added ControlUtil module and stringControls function.

286 : jhr 1194 [2002-05-17]
287 : jhr 1199 Added tyName field to ValueSyntax exception in Controls module
288 :     and path field to registry tree in ControlRegistry module.
289 : jhr 1195
290 :     [2002-05-17]
291 : jhr 1194 Added == and != operators to INT_INF interface. These are a
292 :     placeholder until IntInf moves into the SML/NJ compiler.
293 :    
294 : jhr 1193 [2002-05-16]
295 :     Added mergeWith function to ORD_MAP interface.

302 :     combinators to the Util library.
303 :    
304 :     [2002-03-14]
305 :     Merged in Matthias Blume's Controls library. Warning: the API
306 :     to this library is likely to change as we get some experience
307 :     with it.
308 :    
309 :     [2002-03-11]
310 :     Added consR1 .. consR5 functions to HashCons library. These
311 :     can be used to hash-cons record types.
312 :    
313 : jhr 1081 [2002-02-21]
314 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
315 :     singleton list as input (Chris Okasaki provided the fix).
316 : blume 1077
317 :     [2002-02-12]
318 : jhr 1061 Added implementation of priority queues to Util library (using

321 : jhr 967 [2001-10-19]
322 :     Added new HashCons library.
323 :    
324 :     [2001-10-19]

335 :     The old interface still works, but will be dropped when we move
336 :     to the new Util library.
337 :    
338 :     [2001-04-06]
339 :     Added partition function to ORD_SET interface.
340 :    
341 :     [2001-04-05]
342 :     Added hasProps function to PropList module.
343 :    
344 :     [2001-03-16]
345 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
346 :     line wraps when one of the help lines is longer than the screen
347 :     width. It was also unneccesary.
348 :    
349 :     [2001-02-23]
350 :     Added inDomain function to the various kinds of hash tables.
351 :    
352 : jhr 785 [2001-02-22]

397 :     Added anchorLink style to HTMLDev structure in PP/devices.
398 :    
399 : monnier 498 [1999-12-03]
400 :     Added IntHashTable structure to Util library; this structure is
401 :     a specialization of hash tables to integer keys.
402 : monnier 2
403 : monnier 498 [1999-12-03]
404 :     Added default cases to avoid "match not exhaustive" warnings.
405 :    
406 :     [1999-12-03]
407 :     Added GraphSCCFn functor to Util library, which implements a
408 :     strongly-connected components algorithm on directed graphs (written

415 :     [1999-11-7]
416 :     Made the result signatures of ListSetFn and ListMapFn opaque.
417 :    
418 :     [1999-11-1]
419 :     Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
420 :    
421 : monnier 475 [1999-10-20]
422 :     Fixed bug in RedBlack trees (the linear time construction of
423 :     trees from ordered sequences was producing backwards trees).
424 :    
425 :     [1999-10-18]
426 :     Changed UREF signature so that union, unify, and link operations
427 :     now return a boolean.
428 :    
429 :     [1999-10-18]
430 :     Added peekFn to PropList.newProp return result.
431 :    
432 :     [1999-10-14]
433 :     Added TextIOPP structure to pp-lib.cm (it was not being exported).
434 :    
435 : monnier 469 [1999-09-21]
436 :     Changed the getOpt API. Errors are now reported using a callback
437 :     and both usage and getOpt take records as arguments. Also changed
438 :     the NoArg descriptor to take a function so that imperative argument
439 :     processing can be supported.
440 :    
441 :     [1999-09-20]
442 :     Changed CM files to be compatible with both the old (110.0.x) and
443 :     new (110.20+) versions of CM.
444 :    
445 :     [1999-09-17]
446 :     Added PropList:PROP_LIST structure. This structure implements
447 :     property lists using Stephen Weeks's technique.
448 :    
449 :     [1999-09-17]
450 :     Improved the red-black tree implementations with linear-time union,
451 :     intersection, difference, and filter operations. Also reimplemented
452 :     the delete function in a way that does not require an extra constructor.
453 :    
454 :     [1999-09-09]
455 :     Added Red-Black-Tree implementation of sets and maps. Two new
456 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
457 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
458 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
459 :    
460 :     [1999-09-03]
461 :     Added missing support for WORD and WORD8 format items to Format structure.
462 :     Still need to handle LWORD items!!
463 :    
464 :     [1999-08-17]
465 :     Added DynamicArray:DYNAMIC_ARRAY structure.
466 :    
467 : monnier 411 [1999-07-06]
468 :     Added declarative representation of pretty-printing to PPStreamFn.
469 :     This replaces the PPDescFn and PP_DESC components (which were not
470 :     implemented anyway).
471 :    
472 :     [1999-07-02]
473 :     Moved SockUtil structure into a new INet library. Also split out the
474 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
475 :     are now supported on Win32).
476 :    
477 :     [1999-06-17]
478 :     Added listKeys function to ORD_MAP API.
479 :    
480 :     [1999-06-14]
481 :     Added Riccardo Pucella's GetOpt structure to Util library.
482 :    
483 :     [1999-06-14]

485 :    
486 :     [1999-06-02]
487 :     Merged in some bug fixes from the compiler's version of the IntInf
488 :     structure.
489 :    
490 : monnier 289 [1999-05-05]
491 :     Fixed a couple of bugs in the PP library having to do with nesting
492 :     absolute and relative indentations.
493 :    
494 :     [1999-04-21]
495 :     Added a way to pass control information to a PP device via the PP
496 :     stream (function control in PP_STREAM).
497 :    
498 :     [1999-04-16]
499 :     Added better style support to the HTML PP device.

503 :     signature (and to implementations).
504 :    
505 :     [1998-06-23]
506 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
507 :    
508 :     --------------------------------------------------------------------------------
509 : monnier 106 [1998-04-15] 110 --> 110.5
510 :     --------------------------
511 :    
512 :     There is now a regular expression library (mostly implemented by Riccardo
513 :     Pucella). The implementation separates front-ends (which specify the
514 :     syntax of REs) from back-ends (which implement the matching algorithms).
515 :     Currently, we support AWK syntax as the only front-end and two different
516 :     back-ends.
517 :    
518 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
519 :    
520 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
521 :     Also did some clean-up of the code.
522 :    
523 :    
524 :     --------------------------------------------------------------------------------
525 : monnier 8 [1997-12-07] 109.32 --> 110
526 :     ---------------------------
527 :    
528 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
529 :     to the ORD_MAP signature. These functions fit the pattern of the fold
530 :     functions. (110 patch 3)
531 :    
532 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
533 :     of the optional IntInf structure defined by the SML'97 basis.
534 :    
535 :     Changed the Rand structure to use words as seeds and results. This also
536 :     fixes bug 1047. (110 patch 3)
537 :    
538 : monnier 8 Added a clear operation to the Queue and various hash table structures.
539 :    
540 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
541 :     to ListFormat.scan. Added the function ListFormat.listToString.
542 :    
543 :     Updated the HTML library to the final 3.2 specification. This involved adding
544 :     a new BODY element type (with attributes). Also, removed the header/footer
545 :     arguments to the pretty-printer (they were a gross hack).
546 :    
547 :     Added PathUtil structure to Util library. This is a more general version
548 :     of the old UnixPath module.
549 :    
550 :    
551 :     --------------------------------------------------------------------------------
552 :     [1997-10-01] 109.31 --> 109.32
553 :     ------------------------------
554 :    
555 :     Changed the type of the exec instruction in the Reactive library.
556 :    
557 :    
558 :     --------------------------------------------------------------------------------
559 : monnier 2 [1997-09-09] 109.30 --> 109.31
560 :     ------------------------------
561 :    
562 :     Added the Reactive library, which supports reactive scripting. This is a
563 :     first cut, and hasn't been extensively tested.
564 :    
565 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
566 :     (since the sock prefix was redundant).
567 :    
568 :     Added some bug fixes to IntListSet that had previously been added to
569 :     the ListSetFn implementation.
570 :    
571 :    
572 :     --------------------------------------------------------------------------------
573 :     [1997-07-17] 109.29 --> 109.30
574 :     ------------------------------
575 :    
576 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
577 :    
578 :     The bug fix for unionWith was broken. I think I've got it right this
579 :     time.
580 :    
581 :    
582 :     --------------------------------------------------------------------------------
583 :     [1997-07-17] 109.29 --> 109.30
584 :     ------------------------------
585 :    
586 :     Fixed a bug in the binary-tree and splay-tree implementations of the
587 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
588 :     of arguments to the merging function to be wrong in some cases.
589 :    
590 :     Fixed uses of System.Unsafe.
591 :    
592 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
593 :    
594 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
595 :    
596 :     Added Atom.atom' operation for turning substrings into atoms.
597 :    
598 :    
599 :     --------------------------------------------------------------------------------
600 :     [1997-06-13] 109.28 --> 109.29
601 :     ------------------------------
602 :    
603 :     Added collate operation to ORD_MAP signature.
604 :    
605 :     Added compare operation to ORD_SET signature.
606 :    
607 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
608 :     more general.
609 :    
610 :     Changed the type of the map function in the ORD_SET signature to return
611 :     a new set (instead of a list).
612 :    
613 :    
614 :     --------------------------------------------------------------------------------
615 :     [1997-05-22] 109.27 --> 109.28
616 :     ------------------------------
617 :    
618 :     Changed various sharing constraints to "where type" definitions to
619 :     compile in SML'97.
620 :    
621 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
622 :    
623 :    
624 :     --------------------------------------------------------------------------------
625 :     [1997-03-03] 109.25.1 --> 109.25.2
626 :     ----------------------------------
627 :    
628 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
629 :    
630 :    
631 :     --------------------------------------------------------------------------------
632 :     [1997-02-25] 109.25 --> 109.25.1
633 :     --------------------------------
634 :    
635 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
636 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
637 :     are:
638 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
639 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
640 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
641 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
642 :     val filter : ('a -> bool) -> 'a map -> 'a map
643 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
644 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
645 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map
646 :    
647 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
648 :     support for dynamically rebinding stdIn and stdOut.
649 :    
650 :     Added KeywordFn functor to the Util library. This provides support for
651 :     implementing scanners, where keyword recognition is done outside the
652 :     basic lexical analysis.
653 :    
654 :     Fixed several bugs in the ListSetFn functor.
655 :    
656 :    
657 :     --------------------------------------------------------------------------------
658 :     [1997-01-10] 109.23 --> 109.24
659 :     ------------------------------
660 :    
661 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
662 :     interfaces to provide two forms of the listItems function. listItemsi
663 :     returns a list of (key, value) pairs and listItems returns just the values.
664 :     The previous version of listItems was like listItemsi.
665 :    
666 :     Added a missing case for BASEFONT in CheckHTMLFn.check.
667 :    
668 :    
669 :     --------------------------------------------------------------------------------
670 :     [1996-12-07] 109.21.1 --> 109.22
671 :     --------------------------------
672 :    
673 :     Changed the MONO_DYNAMIC_ARRAY signature to make array an eqtype (also changed
674 :     the implementation of DynamicArrayFn).
675 :    
676 :     Fixed a bug in Array2.column
677 :    
678 :    
679 :     --------------------------------------------------------------------------------
680 :     [1996-10-18] 109.19 --> 109.20
681 :     ------------------------------
682 :    
683 :     Added functions for sending/receiving strings over TCP sockets to the
684 :     SockUtil structure.
685 :    
686 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
687 :    
688 :     Fixed a bug in the implementation of the intersection operation
689 :     in binary sets (BinarySetFn and IntBinarySet).
690 :    
691 :    
692 :     --------------------------------------------------------------------------------
693 :     [1996-10-01] 109.18 --> 109.19
694 :     ------------------------------
695 :    
696 :     Updated the HTML library to the August 21 version of the 3.2 DTD.
697 :    
698 :     Added html-defaults.sml to the HTML Library.
