=head1 NAME

Date::Manip::Changes6 - changes in Date::Manip 6.xx

=head1 SYNOPSIS

This describes the changes made to the Date::Manip module in the 6.xx
series of releases.  Major changes are marked with asterisks (*).

For the most part, Date::Manip has remained backward compatible at
every release, but occasionally, a change is made which is backward
incompatible. These are marked with an exclamation mark (!).

=head1 VERSION 6.61 (planned 2017-12-01)

=head1 VERSION 6.60 (planned 2017-09-01)

=over 4

=item Bug fixes

Fixed a bug where if a recurrence had no interval, start and end dates passed
in to the dates method would not work.  PJ-DSI-DevOps (GitHub #12).

=item Documentation fixes

Clarified Date::Manip::TZ::all_periods.  Based on discussion with
Peter Pfannenschmid.

=back

=head1 VERSION 6.59 (2017-06-01)

=over 4

=item Time zone fixes

Newest zoneinfo data (tzdata 2017b)

=item Documentation fixes

Improved some of the documentation.

=back

=head1 VERSION 6.58 (2017-03-01)

=over 4

=item Better support for $mode in DateCalc.

DateCalc (in DM6) did not support all values for $mode.  Now it does.

=item Bug fixes

Parsing a date like 01/02/2016 and calling printf with %e gave '02' instead
of ' 2'.  RT 119787.

Fixed a problem where the tzdata method of determining the timezone was
producing an error which wasn't correct.  John (GitHub #8)

=item Time zone fixes

Newest zoneinfo data (tzdata 2017a)

=back

=head1 VERSION 6.57 (2016-12-01)

=over 4

=item Time zone fixes

Newest zoneinfo data (tzdata 2016j)

=item Test fixes

A faulty test was failing in a few places.  RT 118705

Another test was failing due to a perl bug that popped up in 5.25.7.  Tweaked
the test to bypass the bug.  RT 118862

=back

=head1 VERSION 6.56 (2016-09-09)

=over 4

=item Test fixes

A faulty test was failing most places.  New release to correct that problem.
RT 117404

=back

=head1 VERSION 6.55 (2016-09-01)

=over 4

=item Fixed bug where C<$::TZ> wasn't used

The C<$::TZ> variable was not getting interpreted correctly when searching
for a timezone.  RT 114949.

=item Fixed bug where recurrences were not parsed correctly

Passing in incorrect values for a field was not trapped in all cases
and it led to problems.  All values passed in to a recurrence are now
correctly checked.  Albert Hilazo (GitHub #7).

=item Fixed a bug in some methods of creating new objects

Some methods of creating new objects based on existing objects did not
correctly use the existing object.  Bug has never been reported, but was
discovered when adding tests to get 100% coverage.

=item Time zone fixes

Newest zoneinfo data (tzdata 2016f)

=item Test fixes

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

=back

=head1 VERSION 6.54 (2016-05-31)

=over 4

=item Deprecation of Date::Manip 5.xx tests

By default, the Date::Manip 5.xx tests will no longer run.  Changes to
the timezone data can cause failures.  Since Date::Manip 5.xx is no longer
supported in any way, these tests will no longer run on a system where
6.xx can be run.  Richard Jelinek.

=item Deprecation of TZ postponed

The deprecation of the TZ variable has been postponed to March 2017.  I
decided that 1 year was not enough notice (especially since not everyone
will have updated Date::Manip since March 2015 when the warning was added.

=item Bug fixes

Changed requirement for ExtUtils::MakeMaker to 6.67_01.  RT 112286

Fixed a bug where a timezone abbreviation was not parsed correctly when
passed in as a value to the SetDate, ForceDate, or TZ config variables.
Based on a report in perlmonks.org.

=item Time zone fixes

Newest zoneinfo data (tzdata 2016d)

Made some improvements to how I handled the timezone data which resulted
in a few of the default timezones being changed.

=item Documentation fixes

Fixed one more typo.  RT 114095

Clarified the Config document.  Based on a report in perlmonks.org.

=back

=head1 VERSION 6.53 (2016-03-02)

=over 4

=item Bug fixes

Date::Manip::Delta::cmp had a bug in it's comparison.  Ian Gibbs.

The secs_since_1970_GMT method was missing a test to see if it was
a valid object.  RT 111915

=item Time zone fixes

Newest zoneinfo data (tzdata 2016a)

=item Documentation fixes

Lots of typos fixed.  I was using podspell to do spell checking, but it was
discarding too much real text (which wasn't getting checked as a result).
Switched to pod2text which does a better job.  RT 110025

=back

=head1 VERSION 6.52 (2015-12-01)

=over 4

=item B<Added date ranges on unmodified dates in Recur>

The date range can now be specified for either the fully modified dates, or
the unmodified dates.  This will make it easier to work with holidays in some
instances.  Based on L<http://perlmonks.org/?node_id=1148735>.

=item B<Added IWn and NWn recurrence modifiers>

Based on L<http://perlmonks.org/?node_id=1148735>.

=item B<(!) Reworked holidays slightly>

Previously, every line in the Holidays section defined a unique holiday.
Now, the names determine the list of holidays.

It is not allowed to have two separate holidays named exactly the same.
It IS allowed to have complex holidays that require two (or more) lines
in the Holidays section to define them completely.

Based on L<http://perlmonks.org/?node_id=1148735>.

=item Bug fixes

Fixed a bug where the RecurRange config variable wasn't getting used.

Fixed a bug where some deltas were not parsed correctly as dates.
RT 109600

=item Time zone fixes

Newest zoneinfo data (tzdata 2015g)

=item Test fixes

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

=back

=head1 VERSION 6.51 (2015-09-01)

=over 4

=item Changes suggested by perlcritic

Played with perlcritic and made a few minor changes based on it's suggestions.
I doubt I will use perlcritic significantly.

=item B<(!) Date::Manip::Delta::value now returns an empty string>

If a delta has an error, or no valid delta in it, the value method returns
an empty string instead of undef.  This is to be consistent with the
Date::Manip::Date::value method which returns an empty string.

=item Bug fixes

Fixed a bug where date/delta calculations with deltas that are too
large was not working correctly.  They now set an error condition
and fail.  RT 105737

Fixed a bug introduced by the previous patch and luckily discovered
pre-release by Tom Wyant.

Fixed code that produced a warning in 5.22.0.  Tom Wyant

=item Improved DM6 ParseDate and ParseDateString

Added C<@opts> argument.  Based on RT 105622.

=item Time zone fixes

Newest zoneinfo data (tzdata 2015f)

Now uses /etc/localtime as a method to determine the local timezone.
Patch supplied in RT 105159 (modified by me).  The patch uses some
code derived from DateTime::TimeZone .

Clearer message when the date is not valid in the timezone.

=item Test fixes

Added a number of new tests based on Devel::Cover.  Over the next several
releases, I intend to continue to add tests until coverage is 100%.

=item Documentation fixes

Fixed a typo.  RT 105546

=back

=head1 VERSION 6.50 (2015-06-01)

=over 4

Not really a bug, but 6.49 got a bunch of NYTprof data bundled with it
by mistake.  It's been removed.  RT 103252

Fixed a bug where information about whether a date was complete or
truncated was discarded.  Jim Avera

Fixed a bug where SetDate with a zone alias failed.

Added the Format_MMMYYYY config variable to allow the truncated format
mmmYYYY to be parsed instead of mmmDDYY.  David W. Morganwalp and RT 103142

Fixed Makefile.PL/Build.PL to correct for a change on perl on windows
which changes a module prereq requirement.  Alexandr Ciornii

=item Time zone fixes

Newest zoneinfo data (tzdata 2015d)

Added aliases for older HP-UX time zones.  RT 104141

Parsing special date formats with timezones is now supported such as:

Christmas at noon PST
   in 3 days at noon PST
   now PST
   epoch 3000000 PST

=item dm_zdump modified

To match the newest version of zdump, the gmtoff is now added at the end
of each line.

=item Bug fixes

Fixed a bug in the printf method that would not handle embedded newlines
correctly (and resulted in an infinite loop if it were preceded by a '%').
Henrique Martins

Fixed a bug where '24:00' was not parsed correctly (though '24:00:00' was).

Fixed a bug where fractional values separated by a comma weren't parsed
correctly.

I made several changes to Build.PL, Makefile.PL, META.yml in order to
improve the quality (or kwalitee) of the module.  None of these should
impact anyone using the module.

=item Time zone fixes

Newest zoneinfo data (tzdata 2013i)

=head1 VERSION 6.40 (2013-06-01)

=over 4

=head1 VERSION 6.38 (2013-01-08)

=over 4

=item B<(*) Tar file format corrected>

Problems were reported on several OSes by people unable to install Date::Manip
(and other modules).  It turns out that the version of tar distributed by
my linux distro (OpenSuSE) uses the 'posix' format instead of the traditional
'gnu' format by default.  This causes problems for some versions of tar.  I
have had reports from OSX, Windows, and SunOS.  Future versions of
Date::Manip will be explicitly distributed in the 'gnu' tar archive format.

Reported by Jay Allen and RT 80594.

=item B<(*) Date::Manip 5.xx end-of-life>

Date::Manip 5.xx is now officially out of support.  I will not be doing
any further work on it.  The only exception is that I will consider
adding user supplied patches on a case-by-case basis.

If at all possible, please use Date::Manip 6.xx instead.

=item B<(!) Removed some deprecated config variables>

The following config variables have been removed.

IntCharSet
   RecurNumFudgeDays

=item Documentation fixes

Spelling error fixed.  RT 80621

=back

=head1 VERSION 6.36 (2012-10-31)

This was an interim release to fix the version numbers (6.35 was
released with all of the version numbers 6.34).

=head1 VERSION 6.35 (2012-10-31)

This was an interim release to fix the problem with the PATH being
replaced.

=over 4

=item Removed dependency on YAML

I've reverted the language data files to perl literals instead of YAML.  Though
not quite as easy to maintain, it solves a few problems.  Patch provided by
Christopher Madsen.

=item Bug fixes

Last versions fix for RT 78566 overrode the PATH even when that wasn't
appropriate.  This is fixed.  Report and patch supplied by RT 80435.

=back

=head1 VERSION 6.34 (2012-09-04)

This is a bug fix so that the PATH won't break non-unix installs.

environments.  Geoff Rowell

=back

=head1 VERSION 6.33 (2012-09-01)

=over 5

=item Improvements to Date::Manip::Delta

Added convert method.  This had been planned since 6.30, but based on
a discussion with Henrique Martins, I moved it up in priority.

Cleaned up handling of delta field lengths (they are now only calculated
once.

Added cmp method.  Henrique Martins

=item Bug fixes

The language modules read from the DATA section, but I never closed the
filehandle.  This is fixed now.  Patch by Doru Theodor Petrescu

Added better loading of DM5/DM6 modules.  RT 78512

Added a secure PATH to TZ.pm for taint reasons.  In response to RT 78566

=item Time zone fixes

Now supports timezones in files with spaces where there should be
underscores.  This occurs in RHEL desktop.  RT 78566

Newest zoneinfo data (tzdata 2012e)

=item Documentation fixes

Minor fix.  Henrique Martins

=back

=head1 VERSION 6.32 (2012-06-01)

=over 4

=item Modified Build.PL

Build.PL now has better support for building (or not building) HTML files.
Apparently this is slow on Windows.  Patch provide in RT 75118.

=item Bug fixes

Fixed a bug in business day calculations.  RT 76336

Fixed a bug where Delta/Recur objects weren't correctly created.  Zsban Ambrus

%<p=NUM>, and %<E=NUM> formats.  Chris Jackson

=item Can now parse formats where the time and zone are not adjacent

A string like 'Jan 21 17:13:27 2010 -0400' can now be parsed.  Requested
on perlmonks ('Can Date::Manip parse a unix timestamp' thread).

=item Added PeriodTimeSep config variable.

This allows you to use a period as a time separator.  Ed Avis

=item Holidays can be used as date strings

You can now parse a holiday name in the Date::Manip::Date::parse method.
For example, parse('Christmas').  Requested by Abigail.

=item Added new recur modifiers

Added WDn, IBD, and NBD modifiers.

=item Added a new date format

You can now parse '2nd day in May' formats. Randy Harmon

=item More flexibility in parsing timezones with both offset and abbrev

If you include both the offset and abbreviation in the timezone portion
of a date, the parenthesis around the abbreviation are now optional, so
you can parse both:

-04:00 (EDT)
   -04:00 EDT

Requested by Steven Melendez.

=item Deltas now support fractional values.

You can now use a delta of 1.5 days.  RT 42699

=item Multiple holidays supported

A date may now have multiple holidays.  Keith Minkler

=item Bug fixes

Fixed a bug where abbreviations were not being examined case insensitively.
Jurgen Muck

The Holidays section may be safely split across multiple config files.
A bug prevented this from working before.

=item Language fixes

The Norwegian translation was broken due to a typo in the language module.

Included complete documentation for each language.

Fixed a couple problems with Danish.  Nicholas Oxhaj

Added Finnish (from a VERY old mail that I overlooked somehow).  Iikka
Virkkunen

Cleaned up the values used by printf directives to give the expected
result.

=item Documentation fixes

Fixed a typo.  Nicholas Bamber

=back

=head1 VERSION 6.30 (2012-01-11)

=over 4

=item B<(*) (!) Reworked deltas>

Much of the delta code was reworked.

The constraint that a day is treated as 24 hours was removed (by
adding the concept of semi-exact deltas) to better handle daylight
saving time calculations.

Made cosmetic changes to which signs will be included in a delta to
make the deltas more readable.  Signs which are the same as the next
higher field will be omitted, even if they cross set boundaries.

Added support for non-normalized deltas.  See the $no_normalize
option for the parse and set methods.

Removed limitations on subtract=2 not working with business
calculations.

Thanks to discussion on perlmonks, and RT 65774 that prompted me to do
this.  I'd been wanting to do it for some time, but the discussion on
perlmonks made me realize that this needed to be much higher priority.

=item B<(!) Modified Delta_Format>

In conjunction with the above work, added the 'semi' mode to
Delta_Format.

=item B<(!) Removed some deprecated config variables>

The following config variables have been removed.

GlobalCnf
   IgnoreGlobalCnf
   PersonalCnf
   PersonalCnfPath
   PathSep

Internal
   DeltaSigns
   UpdateCurrTZ
   ConvTZ
   OldConfigFiles
   ResetWorkDay

=item Time zone fixes

Newest zoneinfo data (tzdata 2011n).  RT 71595

Corrects a bug where +0000 and -0000 offsets were not parsed correctly.
Aaron Hall

The zoneinfo data includes rules more than 20 years in the future, so we
now store 30 years of future dates instead of 20 to catch these rules.

When parsing the timezone portion of the date, timezone abbreviations
now take higher precedence than zone names (since that is how timezone
information is typically specified).  That only impacts dates where
the a timezone name is the same as an abbreviation, such as 'CET'.

Previously, a date with CET in it was interpreted as in the CET timezone.
Now it is interpreted as in a timezone with the CET abbreviation.

=item Better handling of undef in DM6

The date/delta parsing routines in DM6 will now handle an undef argument
without issuing a warning.  Earl C. Ruby III

=item Bug fixes

Fixed a bug with the parse_format %f and %i formats.  Tommi Rintala

Fixed a bug where the Date::Manip::Delta::set function didn't work
to set the month value.

Fixed a bug where parsing some dates near during a DST change failed.

Minor bug fix when using Delta_Format.  Prompted while investigating
RT 41095.

Yuming Philip Xiang

=item B<(*) Set official removal dates for old config variables>

Config variables will be removed 2 years after they are deprecated (except
for the TZ variable which, due to it's wide use, will be kept for 4 years).

=item B<(!) Renamed one Date::Manip::Recur method>

The Date::Manip::Recur::base method has been renamed to basedate .  The
Date::Manip::Recur::base method should return the Date::Manip::Base object
like all the other Date::Manip modules.

=item B<(*) Reworked holidays defined as recurrences>

Improved dealing with the bootstrap problem of defining holidays, especially
those that contain business day flags.  Mike Tonks

=item New features

The printf function will now take multiple format strings and return a list
of values.  Zsban Ambrus

=item Bug fixes

Fixed a bug where GlobalCnf wasn't working.  Peter Edwards

Improved error messages in a few cases.

Fixed a bug where one invalid date/timezone check was ignored.  Morten Bjornsvik

Fixed a bug where '$base2 = new Date::Manip::Base $base1' wasn't working.  RT 67143

Fixed a bug where passing dates in to the Recur->dates method failed.  RT 67144

Fixed a bug where the mode wasn't being preserved correctly for a delta.  RT 67150

Fixed a bug in recurrences where a base date outside of a date range with a very
uncommon recurrence format would not work correctly.

Fixed a problem where the '%s' printf option didn't work in GMT.
Jean-Michel Hiver

=item Time zone fixes

Newest zoneinfo data (tzdata 2011b)

Fixed a bug where the gmtoff method of getting the local timezone was broken.
Martin Zinser.

Fixed the 'env' method of determining the local time zone to allow the
value to be an offset of seconds since UTC.  This allows the VMS
SYS$TIMEZONE_DIFFERENTIAL variable to work correctly.  Martin Zinser.

Removed the SYS$TIMEZONE_RULE method from VMS since the value stored there
is not the name of a timezone (it's a rule in a non-standard format).  Based
on discussion with Martin Zinser.

Improved the order in which aliases, abbreviations, etc., are tested
to test current usage before non-current usage (there were a few cases
where old usages were getting tested before current usage.

=item Language fixes

The module will now die if a language module cannot be loaded (most
likely due to a YAML::Syck issue).  Based on discussion with Martin Zinser.

=item Documentation fixes

Added a sample config file document.  Based on discussion with Rich Duzenbury.

=item B<(*) (!) Reworked recurrences>

Recurrences were reworked in a (slightly) backward incompatible way to
improve their usefulness (and to make them conform to the expected
results). Most recurrences will work the same as previously, but a few will
differ. Most of this was suggested by Jay Jacobs.

A recurring event is now calculated relative to the base date, NOT relative
to a previous event. For example, if a recurrence occurs every month, and
the base date was Jan 31, then previously, recurring events would have
been (in a non-leap year):

D(0)                   = Jan 31
   D(1)  = D(0) + 1 month = Feb 28
   D(2)  = D(1) + 1 month = Mar 28
   ...

The new behavior is:

D(0)                       = Jan 31
   D(1)  = D(0) + 1*(1 month) = Feb 28
   D(2)  = D(0) + 2*(1 month) = Mar 31
   ...

Previously, if a base date were not specified, it was not determined
from the date range. Now, the start date of the date range acts as the
base date.

The meaning of the base date has changed slightly. It is much more
meaningful and useful now.

Added iterator functions.  Daniel LaLiberte

The RecurNumFudgeDays variable is no longer used and is deprecated.

=item Bug fixes

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

Reorganized Base/TZ to get rid of circular references.
   Added end blocks to clean some global variables.
   Got rid of switch/given structures.

=item Test fixes

Added tests from RT 29655 to make sure that the problem never recurs.

=item Documentation fixes

=item B<(!) IntCharSet config variable deprecated>

With better support for international character sets, the old IntCharSet
config variable (which was a bandaid at best) is deprecated. Currently, the
functionality still exists, but it will be removed at some point.

=item New features

Added the Encoding config variable.

Now supports parsing the EXIF date format.  Rhesa Rozendaal

=item Bug fixes

Fixed Build.PL to not require perl 5.010 since the distribution as a whole
does not require that (and I want that fact to be in META.yml).

Fixed a bug where the Date::Manip::Date::set method was broken when setting
individual fields.  Helmut A. Bender

Fixed a bug where set didn't work in Date::Manip::Delta. Patch provided in
RT 59096.

=head1 VERSION 6.10 (2010-04-29)

=over 4

=item B<(*) Combined 5.xx and 6.xx releases into one distribution>

Because the automatic module management tools cpan/cpanp would try
to upgrade Date::Manip to the most recent version, and the most
recent version will only work if perl 5.10.0 or higher is installed,
both the 5.xx and 6.xx releases are now combined into a single
distribution.

This is described more fully in the Date::Manip::Problems document.

=item B<(!) Zones specified by offset>

In all operations involving time zones, the time zone must be determined.
By default, it would take all of the information available (date, ISDST,
etc.) and determine the most likely time zone. It would take every time zone
that matched each piece of information, starting with those that matched
in a standard time followed by those that matched in a daylight saving
time.

When zones are specified by an offset, a standard time would always match
since there are standard time zones that match all year long (the military
time zones A-Z and the standard time zones of the form Etc/GMT+01). As a
result, a daylight saving time match would never occur.

Since (if the date falls during a daylight saving time period) you usually
want to use a time zone that has that offset in daylight saving time,
the default is now to check daylight saving time zones first, followed
by standard times.

See the Date::Manip::TZ manual (under the zone method) for more
information.

=item Bug fixes

Fixed a bug where Date_ConvTZ not working correctly with time zones
specified by offset.  Chris Butler

Fixed a bug where business mode calculations involving minutes was not
handled correctly.  Damien Moore

Fixed a bug where business mode calculations failed in some cases.  RT
56638

=item Time zone fixes

Newest zoneinfo data (tzdata 2010i)

Changed Date::Manip::TZ::zone so "dst" is sometimes the default
$dstflag.  Based on the bug report by Chris Butler.

OpenUNIX puts a colon at the start of some time zones. It's removed.
Jean Hassler

=item Test fixes

Converted tests to Test::Inter

=item Documentation fixes

Fixed a documentation bug in Date::Manip::TZ where "stdonly" was
listed as the default value for $dstflag, but in actuality, "std" is
the default.

=head1 VERSION 6.05 (2009-12-09)

=item B<(!) %z format>

In Date::Manip 5.xx, the %z format in UnixDate printed the offset in
the form -0500. In 6.00, I changed that to -05:00:00, but this broke
RFC 822 compliance.

I've changed %z back to -0500, and introduced a new format (%N) which
returns -05:00:00.

Incidentally, this is the LAST unused letter, so I am now going to
have to either stop adding formats, or add some extended format
syntax. Not sure yet which, but this may involve a backwards
incompatible change in the future.

=item B<(*) Significant speedups.>

Thanks to Moritz Lenz and BrowserUK on perlmonks for suggestions (and
a number of other people on perlmonks for suggestions that I did not
end up using, but which provided a great discussion).

=item Bug fixes

Fixed a bug in parse_date where the current time was getting used
instead of the documented 00:00:00

Bug fix where DateCalc didn't work with $mode in some cases.

Fixed Makefile.PL/Build.PL to handle Win32::TieRegistry requirement.

Changed %z printf behavior back to 5.xx and added %N format. Gilles

New Year's Day defined using a recurrence which might push the observed
day to the previous year was broken. Reported by Jerry Wilcox.

=item Language fixes

Fixed typo in Turkish translation.

Spelling fix in Dutch. Bart Van Loon

=item Additional credits

I have received many suggestions over time which were automatically
handled during the 6.00 rewrite. Although the changes weren't made
because of the suggestions specifically, I wanted to acknowledge
them since I appreciate the suggestions.

I believe the first person to suggest writing Date::Manip as an OO
module was Eduard Derksen.

Delta_Format initialization done outside of the function.  Eric Boehm

Added $subtract to calculation routines. First suggested by Steve Berlage.

Added ability to set individual parts of the date (Date::Manip::Date::set).
First suggested by Martin Thurn.

UnixDate (i.e. Date::Manip::Date::printf) only calculates formats when
they are needed.  Eduard Derksen

Parsing will skip some date/time formats if requested. This was first
suggested by Eduard Derksen.

It has been suggested several times to support multiple languages,
multiple config files, or multiple sets of Date_Init
options. These suggestions (by Meng Fang, Ed Avis, Christian
Campbell, and perhaps others) were at the back of my mind as I
developed the Date::Manip::Base class.

The regular expressions are all i18n friendly in anticipation of much
better support for localization. First suggested by Alex Kapranoff.

Parsing a date ('today', 'Monday') gives a time of '00:00:00'. Suggested
by Mark Aitchison.

Working with fractional days was suggested by Peter van Hardenberg.
This is implemented in Date::Manip::Base::day_of_year method.
