Python-dateutils

=============
- Updated zoneinfo to 2016c
- Fixed parser bug where yearfirst and dayfirst parameters were not being
respected when no separator was present. (gh issue 81 and 217, pr 229)

=============
- Updated zoneinfo to 2016b
- Changed MANIFEST.in to explicitly include test suite in source distributions,
with help from koobs (gh issue 193, pr 194, 201, 221)
- Explicitly set all line-endings to LF, except for the NEWS file, on a
per-repository basis (gh pr 218)
- Fixed an issue with improper caching behavior in rruleset objects (gh issue
104, pr 207)
- Changed to an explicit error when rrulestr strings contain a missing BYDAY
(gh issue 162, pr 211)
- tzfile now correctly handles files containing leapcnt (although the leapcnt
information is not actually used). Contributed by hjoukl (gh issue 146, pr
147)
- Fixed recursive import issue with tz module (gh pr 204)
- Added compatibility between tzwin objects and datetime.time objects (gh issue
216, gh pr 219)
- Refactored monolithic test suite by module (gh issue 61, pr 200 and 206)
- Improved test coverage in the relativedelta module (gh pr 215)
- Adjusted documentation to reflect possibly counter-intuitive properties of
RFC-5545-compliant rrules, and other documentation improvements in the rrule
module (gh issue 105, gh issue 149 - pointer to the solution by phep,
pr 213).

=============
- Updated zoneinfo to 2016a
- zoneinfo_metadata file version increased to 2.0 - the updated updatezinfo.py
script will work with older zoneinfo_metadata.json files, but new metadata
files will not work with older updatezinfo.py versions. Additionally, we have
started hosting our own mirror of the Olson databases on a GitHub pages
site (https://dateutil.github.io/tzdata/) (gh pr #183)
- dateutil zoneinfo tarballs now contain the full zoneinfo_metadata file used
to generate them. (gh issue 27, gh pr 85)
- relativedelta can now be safely subclassed without derived objects reverting
to base relativedelta objects as a result of arithmetic operations.
(lp:1010199, gh issue 44, pr 49)
- relativedelta 'weeks' parameter can now be set and retrieved as a property of
relativedelta instances. (lp: 727525, gh issue 45, pr 49)
- relativedelta now explicitly supports fractional relative weeks, days, hours,
minutes and seconds. Fractional values in absolute parameters (year, day, etc)
are now deprecated. (gh issue 40, pr 190)
- relativedelta objects previously did not use microseconds to determine of two
relativedelta objects were equal. This oversight has been corrected.

- rrule now has an xafter() method for retrieving multiple recurrences after a
specified date. (gh pr 38)
- str(rrule) now returns an RFC2445-compliant rrule string, contributed by
schinckel and armicron (lp:1406305, gh issue 47, prs 50, 62 and 160)
- rrule performance under certain conditions has been significantly improved
thanks to a patch contributed by dekoza, based on an article by Brian Beck
(exogen) (gh pr 136)
- The use of both the 'until' and 'count' parameters is now deprecated as
inconsistent with RFC2445 (gh pr 62, 185)
- Parsing an empty string will now raise a ValueError, rather than returning the
datetime passed to the 'default' parameter. (gh issue 78, pr 187)
- tzwinlocal objects now have a meaningful repr() and str() implementation
(gh issue 148, prs 184 and 186)
- Added equality logic for tzwin and tzwinlocal objects. (gh issue 151,
pr 180, 184)
- Added some flexibility in subclassing timelex, and switched the default
behavior over to using string methods rather than comparing against a fixed
list. (gh pr 122, 139)
- An issue causing tzstr() to crash on Python 2.x was fixed. (lp: 1331576,
gh issue 51, pr 55)
- An issue with string encoding causing exceptions under certain circumstances
when tzname() is called was fixed. (gh issue 60, 74, pr 75)
- Parser issue where calling parse() on dates with no day specified when the
day of the month in the default datetime (which is "today" if unspecified) is
greater than the number of days in the parsed month was fixed (this issue
tended to crop up between the 29th and 31st of the month, for obvious reasons)
(canonical gh issue 25, pr 30, 191)
- Fixed parser issue causing fuzzy_with_tokens to raise an unexpected exception
in certain circumstances. Contributed by MichaelAquilina (gh pr 91)
- Fixed parser issue where years > 100 AD were incorrectly parsed. Contributed
by Bachmann1234 (gh pr 130)
- Fixed parser issue where commas were not a valid separator between seconds
and microseconds, preventing parsing of ISO 8601 dates. Contributed by
ryanss (gh issue 28, pr 106)
- Fixed issue with tzwin encoding in locales with non-Latin alphabets
(gh issue 92, pr 98)
- Fixed an issue where tzwin was not being properly imported on Windows.
Contributed by labrys. (gh pr 134)
- Fixed a problem causing issues importing zoneinfo in certain circumstances.
Issue and solution contributed by alexxv (gh issue 97, pr 99)
- Fixed an issue where dateutil timezones were not compatible with basic time
objects. One of many, many timezone related issues contributed and tested by
labrys. (gh issue 132, pr 181)
- Fixed issue where tzwinlocal had an invalid utcoffset. (gh issue 135,
pr 141, 142)
- Fixed issue with tzwin and tzwinlocal where DST transitions were incorrectly
parsed from the registry. (gh issue 143, pr 178)
- updatezinfo.py no longer suppresses certain OSErrors. Contributed by bjamesv
(gh pr 164)
- An issue that arose when timezone locale changes during runtime has been
fixed by carlosxl and mjschultz (gh issue 100, prs 107, 109)
- Python 3.5 was added to the supported platforms in the metadata (tacaswell
gh pr 159) and the test suites (moreati gh pr 117).
- An issue with tox failing without unittest2 installed in Python 2.6 was fixed
by moreati (gh pr 115)
- Several deprecated functions were replaced in the tests by moreati
(gh pr 116)
- Improved the logic in Travis and Appveyor to alleviate issues where builds
were failing due to connection issues when downloading the IANA timezone
files. In addition to adding our own mirror for the files (gh pr 183), the
download is now retried a number of times (with a delay) (gh pr 177)
- Many failing doctests were fixed by moreati. (gh pr 120)
- Many fixes to the documentation (gh pr 103, gh pr 87 from radarhere,
gh pr 154 from gpoesia, gh pr 156 from awsum, gh pr 168 from ja8zyjits)
- Added a code coverage tool to the CI to help improve the library. (gh pr 182)
- We now have a mailing list - dateutilpython.org, graciously hosted by
Python.org.

=============
- Updated zoneinfo to 2015b.

if not a unicode type. gh 51 (lp:1331576), gh pr 55.
- Fix a parser issue where AM and PM tokens were showing up in fuzzy date
stamps, triggering inappropriate errors. gh 56 (lp: 1428895), gh pr 63.
- Missing function "setcachesize" removed from zoneinfo __all__ list by ryanss,
fixing an issue with wildcard imports of dateutil.zoneinfo. (gh pr 66).

suite.

=============

- Added explicit check for valid hours if AM/PM is specified in parser.
(gh pr 22, issue 21)
- Fix bug in rrule introduced in 2.4.0 where byweekday parameter was not
handled properly. (gh pr 35, issue 34)

- Fix and add test for Python 2.x compatibility with boolean checking of
relativedelta objects. Implemented by nimasmi (gh pr 43) and Cédric Krier
(lp: 1035038)

to parser. (gh pr 36)
