Version 2.5.3 ------------- - Updated zoneinfo to 2016d - Fixed parser bug where unambiguous datetimes fail to parse when dayfirst is set to true. (gh issue #233, pr #234) - Bug in zoneinfo file on platforms such as Google App Engine which do not do not allow importing of subprocess.check_call was reported and fixed by @savraj (gh issue #239, gh pr #240) - Fixed incorrect version in documentation (gh issue #235, pr #243) Version 2.5.2 ------------- - 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) Version 2.5.1 ------------- - 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). Version 2.5.0 ------------- - 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. Contributed by @elprans (gh pr #113) - 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.

(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.

Instead of a cache, all the zones are loaded to memory, but symbolic links are loaded only once, so not much memory is used. - The package is now zip-safe, and universal-wheelable, thanks to changes in the handling of the zoneinfo file. - Fixed tzwin silently not imported on windows python2 - New maintainer, together with new hosting: GitHub, Travis, Read-The-Docs Version 2.2 ----------- - Updated zoneinfo to 2013h - fuzzy_with_tokens parse addon from Christopher Corley - Bug with LANG=C fixed by Mike Gilbert Version 2.1 ----------- - New maintainer - Dateutil now works on Python 2.6, 2.7 and 3.2 from same codebase (with six) - #704047: Ismael Carnales' patch for a new time format - Small bug fixes, thanks for reporters! Version 2.0 ----------- - Ported to Python 3, by Brian Jones. If you need dateutil for Python 2.X, please continue using the 1.X series. - There's no such thing as a "PSF License". This source code is now made available under the Simplified BSD license. See LICENSE for details. Version 1.5 ----------- - As reported by Mathieu Bridon, rrules were matching the bysecond rules incorrectly against byminute in some circumstances when the SECONDLY frequency was in use, due to a copy & paste bug. The problem has been unittested and corrected. - Adam Ryan reported a problem in the relativedelta implementation which affected the yearday parameter in the month of January specifically. This has been unittested and fixed. - Updated timezone information. Version 1.4.1 ------------- - Updated timezone information. Version 1.4 ----------- - Fixed another parser precision problem on conversion of decimal seconds to microseconds, as reported by Erik Brown. Now these issues are gone for real since it's not using floating point arithmetic anymore. - Fixed case where tzrange.utcoffset and tzrange.dst() might fail due to a date being used where a datetime was expected (reported and fixed by Lennart Regebro). - Prevent tzstr from introducing daylight timings in strings that didn't specify them (reported by Lennart Regebro). - Calls like gettz("GMT+3") and gettz("UTC-2") will now return the expected values, instead of the TZ variable behavior. - Fixed DST signal handling in zoneinfo files. Reported by Nicholas F. Fabry and John-Mark Gurney. Version 1.3 ----------- - Fixed precision problem on conversion of decimal seconds to microseconds, as reported by Skip Montanaro. - Fixed bug in constructor of parser, and converted parser classes to new-style classes. Original report and patch by Michael Elsdörfer. - Initialize tzid and comps in tz.py, to prevent the code from ever raising a NameError (even with broken files). Johan Dahlin suggested the fix after a pyflakes run. - Version is now published in dateutil.__version__, as requested by Darren Dale. - All code is compatible with new-style division. Version 1.2 ----------- - Now tzfile will round timezones to full-minutes if necessary, since Python's datetime doesn't support sub-minute offsets. Thanks to Ilpo Nyyssönen for reporting the issue. - Removed bare string exceptions, as reported and fixed by Wilfredo Sánchez Vega. - Fix bug in leap count parsing (reported and fixed by Eugene Oden). Version 1.1 ----------- - Fixed rrule byyearday handling. Abramo Bagnara pointed out that RFC2445 allows negative numbers. - Fixed --prefix handling in setup.py (by Sidnei da Silva). - Now tz.gettz() returns a tzlocal instance when not given any arguments and no other timezone information is found. - Updating timezone information to version 2005q. Version 1.0 ----------- - Fixed parsing of XXhXXm formatted time after day/month/year has been parsed. - Added patch by Jeffrey Harris optimizing rrule.__contains__. Version 0.9 ----------- - Fixed pickling of timezone types, as reported by Andreas Köhler. - Implemented internal timezone information with binary timezone files [1]. datautil.tz.gettz() function will now try to use the system timezone files, and fallback to the internal versions. It's also possible to ask for the internal versions directly by using dateutil.zoneinfo.gettz(). - New tzwin timezone type, allowing access to Windows internal timezones (contributed by Jeffrey Harris). - Fixed parsing of unicode date strings. - Accept parserinfo instances as the parser constructor parameter, besides parserinfo (sub)classes. - Changed weekday to spell the not-set n value as None instead of 0. - Fixed other reported bugs. [1] http://www.twinsun.com/tz/tz-link.htm Version 0.5 ----------- - Removed FREQ_ prefix from rrule frequency constants WARNING: this breaks compatibility with previous versions. - Fixed rrule.between() for cases where "after" is achieved before even starting, as reported by Andreas Köhler. - Fixed two digit zero-year parsing (such as 31-Dec-00), as reported by Jim Abramson, and included test case for this. - Sort exdate and rdate before iterating over them, so that it's not necessary to sort them before adding to the rruleset, as reported by Nicholas Piper.
