7

SYNOPSIS

9       This describes the changes made to the Date::Manip module in the 6.xx
10       series of releases.  Major changes are marked with asterisks (*).
11
12       For the most part, Date::Manip has remained backward compatible at
13       every release, but occasionally, a change is made which is backward
14       incompatible. These are marked with an exclamation mark (!).

47            Newest zoneinfo data (tzdata 2019a).
48

VERSION 6.76 (2019-03-01)

50       Fixed bug in Date::Manip::Date::list_holidays.
51           It was using 'now' instead of the stored date.  Douglas DeStafeno
52
53       Reordered TZ detection methods
54           Moved checking the tzdata files to lower priority to avoid a pretty
55           unusual situation in docker.  Sven Nierlein (GitHub #20)
56
57       Time zone fixes
58           Newest zoneinfo data (tzdata 2018i).  Requested by Shawn C Carroll
59           (GitHub #28)
60

VERSION 6.75 (2018-12-03)

62       Fixed packaging problems
63           Version 6.74 was not packaged correctly.  Version wasn't set
64           correctly in a few files and there were invalid entries in
65           Makefile.PL.  RT 127870.
66

VERSION 6.74 (2018-12-01)

68       Removed travis file from the tarball
69           The tarball had a .travis.yml file in it that wasn't in the
70           MANIFEST file.  Since the MANIFEST file is automatically generated
71           by the perl mkmanifest tool, since it didn't see the .travis.yml
72           file, I have excluded it from the tarball.  Reported by Mohammad S
73           Anwar on GitHub (#23)
74
75       Time zone fixes
76           Newest zoneinfo data (tzdata 2018e)
77

VERSION 6.73 (2018-09-01)

79       Fixed math on non-64-bit architectures
80           Much of the math in Date::Manip::Base is in a 'use integer'
81           section.  This math can overflow in some cases in non-64-bit
82           architectures.  Fixed the cases where this would reasonably occur.
83           Reported by Daniel Albers (GitHub #22).  Also reported and tested
84           in RT 126052.
85
86       Bug in normalizing estimated business deltas
87           While working on the non-64-bit issue, it uncovered a bug where
88           normalizing estimated business deltas was wrong.  It had never been
89           reported, and it was only off by a couple seconds in some rare
90           situations.
91

VERSION 6.72 (2018-06-06)

93       Fixed recurrence bug
94           The fix in the previous version for a rare recurrence problem broke
95           another recurrence form.  It is now corrected.  Michael Schout
96           (GitHub #20)
97
98       Fixed version problem
99           The wrong version was included in two files for some reason.  This
100           is fixed.
101
102       Documentation fixes
103           Fixed a grammatical error reported by Xavier Guimard (GitHub #19).
104

VERSION 6.71 (2018-06-01)

106       Fixed an extremely rare problem with recurrences
107           It is possible to specify a recurrence that never produces a valid
108           date.  In these cases, looking for dates went into an infinite
109           loop.  The MaxRecurAttempts config variable was added which will
110           stop that from happening.  If no occurrence was found, an error
111           condition will be set.  Dean Hamstead (RT 123708)
112
113       Changes file supported
114           It was requested that I include a valid Changes file.  I wrote a
115           simple script to convert the Change6.pod file into a valid Change
116           file.  The Changes6.pod file is still the canonical source of this
117           information!  Requested by H. Merijn Brand
118
119       Fix for timezone determination
120           On MacOS X High Sierra, some of the timezone files were symlinks,
121           but not properly followed.  This was fixed by Stu Tomlinson (GitHub
122           #15).

127       Documentation fixes
128           Minor fix provided by Mohammad S Anwar (GitHub #17)
129

VERSION 6.70 (2018-03-01)

131       (*) (!) Changes to deltas
132           Improved handling of deltas to better support the different types
133           of deltas.  Formalized how the semi-exact portions of the delta are
134           used to produce the results that most people would expect.
135
136           The type can now be specified to guarantee several behaviors.
137           Changed the arguments (in a backward compatible way) to several
138           methods.  Explicitly added a new type (estimated) which was there
139           previously, but could not be manually specified.
140
141           The convert function continues to support converting from a less
142           exact type to a more exact type, but this is deprecated and will be
143           removed in version 7.00.
144
145           This was prompted by a bug reported by Ian Gibbs.
146
147       (*) (!) Deprecated some parts of Date::Manip::Delta
148           The options passed to the set and parse methods have changed.  The
149           old style will be removed in version 7.00.
150
151           Deltas will also no longer support the 'exact' and 'approximate'
152           strings (which have not been supported for some time).  These will
153           be removed in 7.00 as well.
154
155       Deprecation of TZ postponed
156           The deprecation of the TZ variable has been postponed to version
157           7.00.
158
159       Some speed improvements
160           I converted some of the functions to use faster algorithms.
161           Previously, the steps were worked out using logical time/calendar
162           based calculations.  These were replaced with non-intuitive
163           numerical calculations that gave the same result faster.
164
165       Changed behavior if timezone not determined
166           If the system timezone cannot be determined using any of the
167           methods supplied by Date::Manip, operations will be done in the GMT
168           timezone.  Previously, Date::Manip would simply fail to load.
169           Based on a report by Kent Fredric (RT 123229).
170
171       Fixed Makefile.PL
172           The list of what what is provided did not include the path to the
173           file providing each module.  I've fixed the Makefile.PL as well as
174           the META files.  Graham Knop (GitHub #13)
175
176       Time zone fixes
177           Newest zoneinfo data (tzdata 2018c)
178
179       Documentation fixes
180           Rewrote Date::Manip::Delta page to reflect changes, and clean up
181           the documentation in general.
182

VERSION 6.60 (2017-09-01)

184       Bug fixes
185           Fixed a bug where if a recurrence had no interval, start and end
186           dates passed in to the dates method would not work.  PJ-DSI-DevOps
187           (GitHub #12).
188
189       Documentation fixes
190           Clarified Date::Manip::TZ::all_periods.  Based on discussion with
191           Peter Pfannenschmid.
192

VERSION 6.59 (2017-06-01)

194       Time zone fixes
195           Newest zoneinfo data (tzdata 2017b)
196
197       Documentation fixes
198           Improved some of the documentation.
199

VERSION 6.58 (2017-03-01)

201       Better support for $mode in DateCalc.
202           DateCalc (in DM6) did not support all values for $mode.  Now it
203           does.
204
205       Bug fixes
206           Parsing a date like 01/02/2016 and calling printf with %e gave '02'
207           instead of ' 2'.  Robert Wohlfarth (RT 119787).
208
209           Fixed a problem where the tzdata method of determining the timezone
210           was producing an error which wasn't correct.  John (GitHub #8)
211
212       Time zone fixes
213           Newest zoneinfo data (tzdata 2017a)
214

VERSION 6.57 (2016-12-01)

216       Time zone fixes
217           Newest zoneinfo data (tzdata 2016j)
218
219       Test fixes
220           A faulty test was failing in a few places.  RT 118705
221
222           Another test was failing due to a perl bug that popped up in
223           5.25.7.  Tweaked the test to bypass the bug.  Kent Fredric (RT
224           118862)
225

VERSION 6.56 (2016-09-09)

227       Test fixes
228           A faulty test was failing most places.  New release to correct that
229           problem.  Slaven Rezic (RT 117404)
230

VERSION 6.55 (2016-09-01)

232       Fixed bug where $::TZ wasn't used
233           The $::TZ variable was not getting interpreted correctly when
234           searching for a timezone.  Steven Hartland (RT 114949)
235
236       Fixed bug where recurrences were not parsed correctly
237           Passing in incorrect values for a field was not trapped in all
238           cases and it led to problems.  All values passed in to a recurrence
239           are now correctly checked.  Albert Hilazo (GitHub #7).
240
241       Fixed a bug in some methods of creating new objects
242           Some methods of creating new objects based on existing objects did
243           not correctly use the existing object.  Bug has never been
244           reported, but was discovered when adding tests to get 100%
245           coverage.
246
247       Time zone fixes
248           Newest zoneinfo data (tzdata 2016f)
249
250       Test fixes
251           Added a number of new tests based on Devel::Cover.
252

VERSION 6.54 (2016-05-31)

254       Deprecation of Date::Manip 5.xx tests
255           By default, the Date::Manip 5.xx tests will no longer run.  Changes
256           to the timezone data can cause failures.  Since Date::Manip 5.xx is
257           no longer supported in any way, these tests will no longer run on a
258           system where 6.xx can be run.  Richard Jelinek.
259
260       Deprecation of TZ postponed
261           The deprecation of the TZ variable has been postponed to March
262           2017.  I decided that 1 year was not enough notice (especially
263           since not everyone will have updated Date::Manip since March 2015
264           when the warning was added.
265
266       Bug fixes
267           Changed requirement for ExtUtils::MakeMaker to 6.67_01.  Quin
268           Arnold (RT 112286)
269
270           Fixed a bug where a timezone abbreviation was not parsed correctly
271           when passed in as a value to the SetDate, ForceDate, or TZ config
272           variables.  Based on a report in perlmonks.org.
273
274       Time zone fixes
275           Newest zoneinfo data (tzdata 2016d)
276
277           Made some improvements to how I handled the timezone data which
278           resulted in a few of the default timezones being changed.
279
280       Documentation fixes
281           Fixed one more typo.  Gregor Herrmann (RT 114095)
282
283           Clarified the Config document.  Based on a report in perlmonks.org.
284

VERSION 6.53 (2016-03-02)

286       Bug fixes
287           Date::Manip::Delta::cmp had a bug in it's comparison.  Ian Gibbs.
288
289           The secs_since_1970_GMT method was missing a test to see if it was
290           a valid object.  Michael Stevens (RT 111915)
291
292       Time zone fixes
293           Newest zoneinfo data (tzdata 2016a)
294
295       Documentation fixes
296           Lots of typos fixed.  I was using podspell to do spell checking,
297           but it was discarding too much real text (which wasn't getting
298           checked as a result).  Switched to pod2text which does a better
299           job.  Gregor Herrmann (RT 110025)
300

VERSION 6.52 (2015-12-01)

302       Added date ranges on unmodified dates in Recur
303           The date range can now be specified for either the fully modified
304           dates, or the unmodified dates.  This will make it easier to work
305           with holidays in some instances.  Based on
306           <http://perlmonks.org/?node_id=1148735>.
307
308       Added IWn and NWn recurrence modifiers
309           Based on <http://perlmonks.org/?node_id=1148735>.
310
311       (!) Reworked holidays slightly
312           Previously, every line in the Holidays section defined a unique
313           holiday.  Now, the names determine the list of holidays.
314
315           It is not allowed to have two separate holidays named exactly the
316           same.  It IS allowed to have complex holidays that require two (or
317           more) lines in the Holidays section to define them completely.
318
319           Based on <http://perlmonks.org/?node_id=1148735>.
320
321       Bug fixes
322           Fixed a bug where the RecurRange config variable wasn't getting
323           used.
324
325           Fixed a bug where some deltas were not parsed correctly as dates.

332           Added a number of new tests based on Devel::Cover.
333

VERSION 6.51 (2015-09-01)

335       Changes suggested by perlcritic
336           Played with perlcritic and made a few minor changes based on it's
337           suggestions.  I doubt I will use perlcritic significantly.
338
339       (!) Date::Manip::Delta::value now returns an empty string
340           If a delta has an error, or no valid delta in it, the value method
341           returns an empty string instead of undef.  This is to be consistent
342           with the Date::Manip::Date::value method which returns an empty
343           string.
344
345       Bug fixes
346           Fixed a bug where date/delta calculations with deltas that are too
347           large was not working correctly.  They now set an error condition
348           and fail.  Jared Selengut (RT 105737)
349
350           Fixed a bug introduced by the previous patch and luckily discovered
351           pre-release by Tom Wyant.
352
353           Fixed code that produced a warning in 5.22.0.  Tom Wyant
354
355       Improved DM6 ParseDate and ParseDateString
356           Added @opts argument.  Based on report by Vitaly Shupak (RT
357           105622).
358
359       Time zone fixes
360           Newest zoneinfo data (tzdata 2015f)
361
362           Now uses /etc/localtime as a method to determine the local
363           timezone.  Patch supplied by Tom Wyant (RT 105159) (modified by
364           me).  The patch uses some code derived from DateTime::TimeZone .
365
366           Clearer message when the date is not valid in the timezone.
367
368       Test fixes
369           Added a number of new tests based on Devel::Cover.  Over the next
370           several releases, I intend to continue to add tests until coverage
371           is 100%.
372
373       Documentation fixes
374           Fixed a typo.  Gregor Herrmann (RT 105546)
375

VERSION 6.50 (2015-06-01)

377       Bug fixes
378           Not really a bug, but 6.49 got a bunch of NYTprof data bundled with
379           it by mistake.  It's been removed.  Olivier Mengue (RT 103252)
380
381           Fixed a bug where information about whether a date was complete or
382           truncated was discarded.  Jim Avera
383
384           Fixed a bug where SetDate with a zone alias failed.
385
386           Added the Format_MMMYYYY config variable to allow the truncated
387           format mmmYYYY to be parsed instead of mmmDDYY.  David W.
388           Morganwalp and Glenn Golden (RT 103142)
389
390           Fixed Makefile.PL/Build.PL to correct for a change on perl on
391           windows which changes a module prereq requirement.  Alexandr
392           Ciornii

429       parse_time now parses ISO 8601 times
430           The parse_time routine wouldn't correctly parse ISO 8601 times.
431           This is now fixed.
432
433       Parsing special dates with timezones now works
434           Parsing special date formats with timezones is now supported such

446       Bug fixes
447           Fixed a bug in the printf method that would not handle embedded
448           newlines correctly (and resulted in an infinite loop if it were
449           preceded by a '%').  Henrique Martins
450
451           Fixed a bug where '24:00' was not parsed correctly (though
452           '24:00:00' was).

582           you to force a parsed delta to semi or approx where appropriate.
583           This was added.  Based on RT 82991.
584
585       Added get_config method

VERSION 6.38 (2013-01-08)

599       (*) Tar file format corrected
600           Problems were reported on several OSes by people unable to install
601           Date::Manip (and other modules).  It turns out that the version of
602           tar distributed by my linux distro (OpenSuSE) uses the 'posix'
603           format instead of the traditional 'gnu' format by default.  This
604           causes problems for some versions of tar.  I have had reports from
605           OSX, Windows, and SunOS.  Future versions of Date::Manip will be
606           explicitly distributed in the 'gnu' tar archive format.
607
608           Reported by Jay Allen and John Ralls (RT 80594).
609
610       (*) Date::Manip 5.xx end-of-life
611           Date::Manip 5.xx is now officially out of support.  I will not be
612           doing any further work on it.  The only exception is that I will
613           consider adding user supplied patches on a case-by-case basis.
614
615           If at all possible, please use Date::Manip 6.xx instead.
616
617       (!) Removed some deprecated config variables
618           The following config variables have been removed.

VERSION 6.36 (2012-10-31)

635       Fix version numbers
636           This was an interim release to fix the version numbers (6.35 was
637           released with all of the version numbers 6.34).
638

VERSION 6.35 (2012-10-31)

640       Fix PATH
641           This version was an interim release to fix the problem with the
642           PATH being replaced.
643
644       Removed dependency on YAML
645           I've reverted the language data files to perl literals instead of
646           YAML.  Though not quite as easy to maintain, it solves a few
647           problems.  Patch provided by Christopher Madsen.
648
649       Bug fixes
650           Last versions fix for RT 78566 overrode the PATH even when that
651           wasn't appropriate.  This is fixed.  Report and patch supplied by
652           Tom Wyant (RT 80435).
653

VERSION 6.34 (2012-09-04)

656
657       Bug fixes
658           Put the PATH inside the Unix section so it doesn't affect non-unix
659           environments.  Geoff Rowell
660

VERSION 6.33 (2012-09-01)

662       Improvements to Date::Manip::Delta
663            Added convert method.  This had been planned since 6.30, but based
664            on a discussion with Henrique Martins, I moved it up in priority.
665
666            Cleaned up handling of delta field lengths (they are now only
667            calculated once.
668
669            Added cmp method.  Henrique Martins
670
671       Bug fixes
672            The language modules read from the DATA section, but I never
673            closed the filehandle.  This is fixed now.  Patch by Doru Theodor
674            Petrescu
675
676            Added better loading of DM5/DM6 modules.  Evan Carroll (RT 78152)

691       Modified Build.PL
692           Build.PL now has better support for building (or not building) HTML
693           files.  Apparently this is slow on Windows.  Patch provide by Manoj
694           Kumar (RT 75118)

711           files.
712

VERSION 6.31 (2012-03-01)

714       Added extended formats to printf method.
715           These include the %<A=NUM>, %<a=NUM>, %<v=NUM>, %<B=NUM>, %<b=NUM>,
716           %<p=NUM>, and %<E=NUM> formats.  Chris Jackson
717
718       Can now parse formats where the time and zone are not adjacent
719           A string like 'Jan 21 17:13:27 2010 -0400' can now be parsed.
720           Requested on perlmonks ('Can Date::Manip parse a unix timestamp'
721           thread).
722
723       Added PeriodTimeSep config variable.
724           This allows you to use a period as a time separator.  Ed Avis
725
726       Holidays can be used as date strings
727           You can now parse a holiday name in the Date::Manip::Date::parse
728           method.  For example, parse('Christmas').  Requested by Abigail.
729
730       Added new recur modifiers
731           Added WDn, IBD, and NBD modifiers.
732
733       Added a new date format
734           You can now parse '2nd day in May' formats. Randy Harmon
735
736       More flexibility in parsing timezones with both offset and abbrev
737           If you include both the offset and abbreviation in the timezone
738           portion of a date, the parenthesis around the abbreviation are now
739           optional, so you can parse both:
740
741              -04:00 (EDT)
742              -04:00 EDT
743
744           Requested by Steven Melendez.
745
746       Deltas now support fractional values.
747           You can now use a delta of 1.5 days.  Martin Thurn (RT 42699)
748
749       Multiple holidays supported
750           A date may now have multiple holidays.  Keith Minkler
751
752       Bug fixes
753           Fixed a bug where abbreviations were not being examined case
754           insensitively.  Jurgen Muck
755
756           The Holidays section may be safely split across multiple config
757           files.  A bug prevented this from working before.
758
759       Language fixes
760           The Norwegian translation was broken due to a typo in the language
761           module.
762
763           Included complete documentation for each language.
764
765           Fixed a couple problems with Danish.  Nicholas Oxhaj
766
767           Added Finnish (from a VERY old mail that I overlooked somehow).
768           Iikka Virkkunen
769
770           Cleaned up the values used by printf directives to give the
771           expected result.

VERSION 6.30 (2012-01-11)

777       (*) (!) Reworked deltas
778           Much of the delta code was reworked.
779
780           The constraint that a day is treated as 24 hours was removed (by
781           adding the concept of semi-exact deltas) to better handle daylight
782           saving time calculations.
783
784           Made cosmetic changes to which signs will be included in a delta to
785           make the deltas more readable.  Signs which are the same as the
786           next higher field will be omitted, even if they cross set
787           boundaries.
788
789           Added support for non-normalized deltas.  See the $no_normalize
790           option for the parse and set methods.
791
792           Removed limitations on subtract=2 not working with business
793           calculations.
794
795           Thanks to discussion on perlmonks, and RT 65774 that prompted me to
796           do this.  I'd been wanting to do it for some time, but the
797           discussion on perlmonks made me realize that this needed to be much
798           higher priority.
799
800       (!) Modified Delta_Format
801           In conjunction with the above work, added the 'semi' mode to
802           Delta_Format.
803
804       (!) Removed some deprecated config variables
805           The following config variables have been removed.

824           correctly.  Aaron Hall
825
826           The zoneinfo data includes rules more than 20 years in the future,
827           so we now store 30 years of future dates instead of 20 to catch
828           these rules.
829
830           When parsing the timezone portion of the date, timezone
831           abbreviations now take higher precedence than zone names (since
832           that is how timezone information is typically specified).  That
833           only impacts dates where the a timezone name is the same as an
834           abbreviation, such as 'CET'.
835
836           Previously, a date with CET in it was interpreted as in the CET
837           timezone.  Now it is interpreted as in a timezone with the CET
838           abbreviation.
839
840       Better handling of undef in DM6
841           The date/delta parsing routines in DM6 will now handle an undef

932
933           Fixed a bug where the gmtoff method of getting the local timezone
934           was broken.  Martin Zinser.
935
936           Fixed the 'env' method of determining the local time zone to allow
937           the value to be an offset of seconds since UTC.  This allows the
938           VMS SYS$TIMEZONE_DIFFERENTIAL variable to work correctly.  Martin
939           Zinser.
940
941           Removed the SYS$TIMEZONE_RULE method from VMS since the value
942           stored there is not the name of a timezone (it's a rule in a non-
943           standard format).  Based on discussion with Martin Zinser.
944
945           Improved the order in which aliases, abbreviations, etc., are
946           tested to test current usage before non-current usage (there were a
947           few cases where old usages were getting tested before current
948           usage.
949
950       Language fixes
951           The module will now die if a language module cannot be loaded (most
952           likely due to a YAML::Syck issue).  Based on discussion with Martin
953           Zinser.
954

VERSION 6.20 (2010-12-01)

977       (*) (!) Reworked recurrences
978           Recurrences were reworked in a (slightly) backward incompatible way
979           to improve their usefulness (and to make them conform to the
980           expected results). Most recurrences will work the same as
981           previously, but a few will differ. Most of this was suggested by
982           Jay Jacobs.
983
984           A recurring event is now calculated relative to the base date, NOT
985           relative to a previous event. For example, if a recurrence occurs
986           every month, and the base date was Jan 31, then previously,
987           recurring events would have been (in a non-leap year):
988
989              D(0)                   = Jan 31
990              D(1)  = D(0) + 1 month = Feb 28
991              D(2)  = D(1) + 1 month = Mar 28
992              ...
993
994           The new behavior is:
995
996              D(0)                       = Jan 31
997              D(1)  = D(0) + 1*(1 month) = Feb 28
998              D(2)  = D(0) + 2*(1 month) = Mar 31
999              ...
1000
1001           Previously, if a base date were not specified, it was not
1002           determined from the date range. Now, the start date of the date
1003           range acts as the base date.
1004
1005           The meaning of the base date has changed slightly. It is much more
1006           meaningful and useful now.
1007
1008           Added iterator functions.  Daniel LaLiberte
1009
1010           The RecurNumFudgeDays variable is no longer used and is deprecated.

1035       Bug fixes
1036           Several changes to try to get rid of a memory leaks reported in RT
1037           54937.  Huge thanks to BrowserUK on perlmonks for help.
1038           Unfortunately, it ended up being a bug in perl, and will only be
1039           resolved when that bug is fixed. See the Date::Manip::Problems
1040           document for more information.
1041

1063       Documentation fixes
1064           Fixed documentation problem with the new_* methods in

VERSION 6.12 (2010-09-27)

1071       (!) IntCharSet config variable deprecated
1072           With better support for international character sets, the old
1073           IntCharSet config variable (which was a bandaid at best) is
1074           deprecated. Currently, the functionality still exists, but it will
1075           be removed at some point.
1076
1077       New features

1082       Bug fixes
1083           Fixed Build.PL to not require perl 5.010 since the distribution as

1085           META.yml).
1086
1087           Fixed a bug where the Date::Manip::Date::set method was broken when
1088           setting individual fields.  Helmut A. Bender

1113           requirement.
1114

VERSION 6.10 (2010-04-29)

1116       (*) Combined 5.xx and 6.xx releases into one distribution
1117           Because the automatic module management tools cpan/cpanp would try
1118           to upgrade Date::Manip to the most recent version, and the most
1119           recent version will only work if perl 5.10.0 or higher is
1120           installed, both the 5.xx and 6.xx releases are now combined into a
1121           single distribution.
1122
1123           This is described more fully in the Date::Manip::Problems document.
1124
1125       (!) Zones specified by offset
1126           In all operations involving time zones, the time zone must be
1127           determined.  By default, it would take all of the information
1128           available (date, ISDST, etc.) and determine the most likely time
1129           zone. It would take every time zone that matched each piece of
1130           information, starting with those that matched in a standard time
1131           followed by those that matched in a daylight saving time.
1132
1133           When zones are specified by an offset, a standard time would always
1134           match since there are standard time zones that match all year long
1135           (the military time zones A-Z and the standard time zones of the
1136           form Etc/GMT+01). As a result, a daylight saving time match would
1137           never occur.
1138
1139           Since (if the date falls during a daylight saving time period) you
1140           usually want to use a time zone that has that offset in daylight
1141           saving time, the default is now to check daylight saving time zones
1142           first, followed by standard times.
1143
1144           See the Date::Manip::TZ manual (under the zone method) for more
1145           information.

1147       Bug fixes

1207           broke RFC 822 compliance.

1209           I've changed %z back to -0500, and introduced a new format (%N)
1210           which returns -05:00:00.
1211
1212           Incidentally, this is the LAST unused letter, so I am now going to
1213           have to either stop adding formats, or add some extended format
1214           syntax. Not sure yet which, but this may involve a backwards
1215           incompatible change in the future.
1216
1217       (*) Significant speedups.
1218           Thanks to Moritz Lenz and BrowserUK on perlmonks for suggestions
1219           (and a number of other people on perlmonks for suggestions that I
1220           did not end up using, but which provided a great discussion).
1221
1222       Bug fixes
1223           Fixed a bug in parse_date where the current time was getting used
1224           instead of the documented 00:00:00
1225
1226           Bug fix where DateCalc didn't work with $mode in some cases.
1227
1228           Fixed Makefile.PL/Build.PL to handle Win32::TieRegistry
1229           requirement.
1230
1231           Changed %z printf behavior back to 5.xx and added %N format. Gilles
1232           Lamiral
1233
1234           Added dm_date example script.
1235
1236       Time zone fixes
1237           Fixed bug where non-English Windows versions didn't get the time
1238           zone. Thanks to Rene Schickbauer for testing.
1239
1240       Test fixes
1241           Reduced the precision of 1 test to avoid a rounding difference when
1242           using a perl compiled with uselongdouble.  Andreas Koenig

VERSION 6.04 (2009-11-25)

1245       Bug fixes
1246           Fixed a bug where events were not interpreted in the correct time
1247           zone if SetDate/ForceDate used.
1248

VERSION 6.03 (2009-11-24)

1250       Bug fixes
1251           Corrects a backward incompatibility with UnixDate. Rene Schickbauer
1252
1253       Test fixes
1254           A couple more corrections to the tests.
1255

VERSION 6.02 (2009-11-24)

1257       Bug fixes
1258           Disabled curr_zone_methods when taint checking on. I believe that
1259           Date::Manip is completely taint friendly at this point.
1260
1261       Test fixes
1262           A quick fix to make sure that the tests run correctly in other time
1263           zones.
1264

VERSION 6.01 (2009-11-23)

1266       Bug fixes
1267           (*) Fixed a bug where dates were sometimes getting the wrong time
1268           zone when SetDate/ForceDate in effect.
1269

VERSION 6.00 (2009-11-23)

1271       First release of the 6.xx series
1272           Date::Manip 6.00 is a total rethink of the module, and a nearly
1273           complete rewrite. Please refer to the Date::Manip::Changes5to6
1274           document for a list of incompatible changes.
1275
1276       Reorganization
1277           (*) Massive reorganization and near total rewrite.
1278
1279           (*) Broke into several smaller modules
1280
1281       New Features
1282           (*) Full time zone support (using tzdata 2009s)
1283
1284           Added some functionality (suggested by James Elson to improve
1285           setting the "current time".  Done with the ForceDate config
1286           variable.
1287
1288           (*) Converted languages to YAML for much easier maintenance. Patch
1289           and suggestion provided by Evan Carroll
1290
1291           Added much better formats for deltas. Suggested by Jim Hranicky.
1292
1293           Borrowed the _FindWindowsTZName function from the DateTime-TimeZone
1294           module.
1295
1296           Added SetDate config variable (based on a suggestion by Christian
1297           Campbell).
1298
1299           Added parse_format which was first suggested by Kim Ryan.
1300
1301       Other changes
1302           Several config variables deprecated
1303
1304           Thanks to Jonathan Hogue for helping test Windows additions.
1305
1306       Bug fixes (correcting problems in the 5.xx releases)
1307           Fixed a bug where "YYtoYYYY=c" wouldn't work.
1308
1309           VMS bugfix to not call `date` command.  Lane
1310
1311           New Year's Day defined using a recurrence which might push the
1312           observed day to the previous year was broken. Reported by Jerry
1313           Wilcox.
1314
1315       Language fixes
1316           Fixed typo in Turkish translation.
1317
1318           Spelling fix in Dutch. Bart Van Loon
1319
1320       Additional credits
1321           I have received many suggestions over time which were automatically
1322           handled during the 6.00 rewrite. Although the changes weren't made
1323           because of the suggestions specifically, I wanted to acknowledge
1324           them since I appreciate the suggestions.
1325
1326           I believe the first person to suggest writing Date::Manip as an OO
1327           module was Eduard Derksen.
1328
1329           Delta_Format initialization done outside of the function.  Eric
1330           Boehm
1331
1332           Added $subtract to calculation routines. First suggested by Steve
1333           Berlage.
1334
1335           Added ability to set individual parts of the date
1336           (Date::Manip::Date::set).  First suggested by Martin Thurn.
1337
1338           UnixDate (i.e. Date::Manip::Date::printf) only calculates formats
1339           when they are needed.  Eduard Derksen
1340
1341           Parsing will skip some date/time formats if requested. This was
1342           first suggested by Eduard Derksen.
1343
1344           It has been suggested several times to support multiple languages,
1345           multiple config files, or multiple sets of Date_Init options. These
1346           suggestions (by Meng Fang, Ed Avis, Christian Campbell, and perhaps
1347           others) were at the back of my mind as I developed the
1348           Date::Manip::Base class.
1349
1350           The regular expressions are all i18n friendly in anticipation of
1351           much better support for localization. First suggested by Alex
1352           Kapranoff.
1353
1354           Parsing a date ('today', 'Monday') gives a time of '00:00:00'.
1355           Suggested by Mark Aitchison.
1356
1357           Working with fractional days was suggested by Peter van Hardenberg.
1358           This is implemented in Date::Manip::Base::day_of_year method.
