Ambiguous dates and times can now 226 be safely represented by all dateutil time zones. Many thanks to Alexander 227 Belopolski (@abalkin) and Tim Peters @tim-one for their inputs on how to 228 address this. Original issues reported by Yupeng and @zed (lP: 1390262, 229 gh issues #57, #112, #249, #284, #286, prs #127, #225, #248, #264, #302). 230 - Added new methods for working with ambiguous and imaginary dates to the tz 231 module. datetime_ambiguous() determines if a datetime is ambiguous for a given 232 zone and datetime_exists() determines if a datetime exists in a given zone. 233 This works for all fold-aware datetimes, not just those provided by dateutil. 234 (gh issue #253, gh pr #302) 235 - Fixed an issue where dst() in Portugal in 1996 was returning the wrong value 236 in tz.tzfile objects. Reported by @abalkin (gh issue #128, pr #225) 237 - Fixed an issue where zoneinfo.ZoneInfoFile errors were not being properly 238 deep-copied. (gh issue #226, pr #225) 239 - Refactored tzwin and tzrange as a subclass of a common class, tzrangebase, as 240 there was substantial overlapping functionality. As part of this change, 241 tzrange and tzstr now expose a transitions() function, which returns the 242 DST on and off transitions for a given year. (gh issue #260, pr #302) 243 - Deprecated zoneinfo.gettz() due to confusion with tz.gettz(), in favor of 244 get() method of zoneinfo.ZoneInfoFile objects. (gh issue #11, pr #310) 245 - For non-character, non-stream arguments, parser.parse now raises TypeError 246 instead of AttributeError. (gh issues #171, #269, pr #247) 247 - Fixed an issue where tzfile objects were not properly handling dst() and 248 tzname() when attached to datetime.time objects. Reported by @ovacephaloid. 249 (gh issue #292, pr #309) 250 - /usr/share/lib/zoneinfo was added to TZPATHS for compatibility with Solaris 251 systems. Reported by @dhduvall (gh issue #276, pr #307) 252 - tzoffset and tzrange objects now accept either a number of seconds or a 253 datetime.timedelta() object wherever previously only a number of seconds was 254 allowed. (gh pr #264, #277) 255 - datetime.timedelta objects can now be added to relativedelta objects. Reported 256 and added by Alec Nikolas Reiter (@justanr) (gh issue #282, pr #283 257 - Refactored relativedelta.weekday and rrule.weekday into a common base class 258 to reduce code duplication. (gh issue #140, pr #311) 259 - An issue where the WKST parameter was improperly rendering in str(rrule) was 260 reported and fixed by Daniel LePage (@dplepage). (gh issue #262, pr #263) 261 - A replace() method has been added to rrule objects by @jendas1, which creates 262 new rrule with modified attributes, analogous to datetime.replace (gh pr #167) 263 - Made some significant performance improvements to rrule objects in Python 2.x 264 (gh pr #245) 265 - All classes defining equality functions now return NotImplemented when 266 compared to unsupported classes, rather than raising TypeError, to allow other 267 classes to provide fallback support. (gh pr #236) 268 - Several classes have been marked as explicitly unhashable to maintain 269 identical behavior between Python 2 and 3. Submitted by Roy Williams 270 (@rowillia) (gh pr #296) 271 - Trailing whitespace in easter.py has been removed. Submitted by @OmgImAlexis 272 (gh pr #299) 273 - Windows-only batch files in build scripts had line endings switched to CRLF. 274 (gh pr #237) 275 - @adamchainz updated the documentation links to reflect that the canonical 276 location for readthedocs links is now at .io, not .org. (gh pr #272) 277 - Made some changes to the CI and codecov to test against newer versions of 278 Python and pypy, and to adjust the code coverage requirements. For the moment, 279 full pypy3 compatibility is not supported until a new release is available, 280 due to upstream bugs in the old version affecting PEP-495 support. 281 (gh prs #265, #266, #304, #308) 282 - The full PGP signing key fingerprint was added to the README.md in favor of 283 the previously used long-id. Reported by @valholl (gh issue #287, pr #304) 284 - Updated zoneinfo to 2016i.

Additionally, we have 334 started hosting our own mirror of the Olson databases on a github pages 335 site (https://dateutil.github.io/tzdata/) (gh pr #183) 336 - dateutil zoneinfo tarballs now contain the full zoneinfo_metadata file used 337 to generate them. (gh issue #27, gh pr #85) 338 - relativedelta can now be safely subclassed without derived objects reverting 339 to base relativedelta objects as a result of arithmetic operations. 340 (lp:1010199, gh issue #44, pr #49) 341 - relativedelta 'weeks' parameter can now be set and retrieved as a property of 342 relativedelta instances. (lp: 727525, gh issue #45, pr #49) 343 - relativedelta now explicitly supports fractional relative weeks, days, hours, 344 minutes and seconds. Fractional values in absolute parameters (year, day, etc) 345 are now deprecated. (gh issue #40, pr #190) 346 - relativedelta objects previously did not use microseconds to determine of two 347 relativedelta objects were equal.

(gh pr #120) 411 - Many fixes to the documentation (gh pr #103, gh pr #87 from @radarhere, 412 gh pr #154 from @gpoesia, gh pr #156 from @awsum, gh pr #168 from @ja8zyjits) 413 - Added a code coverage tool to the CI to help improve the library. (gh pr #182) 414 - We now have a mailing list - dateutil (a] python.org, graciously hosted by 415 Python.org. 416 417 418 Version 2.4.2 419 ============= 420 - Updated zoneinfo to 2015b. 421 - Fixed issue with parsing of tzstr on Python 2.7.x; tzstr will now be decoded 422 if not a unicode type. gh #51 (lp:1331576), gh pr #55. 423 - Fix a parser issue where AM and PM tokens were showing up in fuzzy date 424 stamps, triggering inappropriate errors. gh #56 (lp: 1428895), gh pr #63. 425 - Missing function "setcachesize" removed from zoneinfo __all__ list by @ryanss, 426 fixing an issue with wildcard imports of dateutil.zoneinfo. (gh pr #66). 427 - (PyPI only) Fix an issue with source distributions not including the test 428 suite. 429 430 431 Version 2.4.1 432 ============= 433 434 - Added explicit check for valid hours if AM/PM is specified in parser. 435 (gh pr #22, issue #21) 436 - Fix bug in rrule introduced in 2.4.0 where byweekday parameter was not 437 handled properly. (gh pr #35, issue #34) 438 - Fix error where parser allowed some invalid dates, overwriting existing hours 439 with the last 2-digit number in the string. (gh pr #32, issue #31) 440 - Fix and add test for Python 2.x compatibility with boolean checking of 441 relativedelta objects. Implemented by @nimasmi (gh pr #43) and Cdric Krier 442 (lp: 1035038) 443 - Replaced parse() calls with explicit datetime objects in unit tests unrelated 444 to parser. (gh pr #36) 445 - Changed private _byxxx from sets to sorted tuples and fixed one currently 446 unreachable bug in _construct_byset. (gh pr #54) 447 - Additional documentation for parser (gh pr #29, #33, #41) and rrule. 448 - Formatting fixes to documentation of rrule and README.rst. 449 - Updated zoneinfo to 2015a. 450 451 Version 2.4.0 452 ============= 453 454 - Fix an issue with relativedelta and freezegun (lp:1374022) 455 - Fix tzinfo in windows for timezones without dst (lp:1010050, gh #2) 456 - Ignore missing timezones in windows like in POSIX 457 - Fix minimal version requirement for six (gh #6) 458 - Many rrule changes and fixes by @pganssle (gh pull requests #13 #14 #17), 459 including defusing some infinite loops (gh #4) 460 461 Version 2.3 462 =========== 463 464 - Cleanup directory structure, moved test.py to dateutil/tests/test.py 465 466 - Changed many aspects of dealing with the zone info file. Instead of a cache, 467 all the zones are loaded to memory, but symbolic links are loaded only once, 468 so not much memory is used. 469 470 - The package is now zip-safe, and universal-wheelable, thanks to changes in 471 the handling of the zoneinfo file. 472 473 - Fixed tzwin silently not imported on windows python2 474 475 - New maintainer, together with new hosting: GitHub, Travis, Read-The-Docs 476 477 Version 2.2 478 =========== 479 480 - Updated zoneinfo to 2013h 481 482 - fuzzy_with_tokens parse addon from Christopher Corley 483 484 - Bug with LANG=C fixed by Mike Gilbert 485 486 Version 2.1 487 =========== 488 489 - New maintainer 490 491 - Dateutil now works on Python 2.6, 2.7 and 3.2 from same codebase (with six) 492 493 - #704047: Ismael Carnales' patch for a new time format 494 495 - Small bug fixes, thanks for reporters! 496 497 498 Version 2.0 499 =========== 500 501 - Ported to Python 3, by Brian Jones. If you need dateutil for Python 2.X, 502 please continue using the 1.X series. 503 504 - There's no such thing as a "PSF License". This source code is now 505 made available under the Simplified BSD license. See LICENSE for 506 details. 507 508 Version 1.5 509 =========== 510 511 - As reported by Mathieu Bridon, rrules were matching the bysecond rules 512 incorrectly against byminute in some circumstances when the SECONDLY 513 frequency was in use, due to a copy & paste bug. The problem has been 514 unittested and corrected. 515 516 - Adam Ryan reported a problem in the relativedelta implementation which 517 affected the yearday parameter in the month of January specifically. 518 This has been unittested and fixed. 519 520 - Updated timezone information. 521 522 523 Version 1.4.1 524 ============= 525 526 - Updated timezone information. 527 528 529 Version 1.4 530 =========== 531 532 - Fixed another parser precision problem on conversion of decimal seconds 533 to microseconds, as reported by Erik Brown. Now these issues are gone 534 for real since it's not using floating point arithmetic anymore. 535 536 - Fixed case where tzrange.utcoffset and tzrange.dst() might fail due 537 to a date being used where a datetime was expected (reported and fixed 538 by Lennart Regebro). 539 540 - Prevent tzstr from introducing daylight timings in strings that didn't 541 specify them (reported by Lennart Regebro). 542 543 - Calls like gettz("GMT+3") and gettz("UTC-2") will now return the 544 expected values, instead of the TZ variable behavior. 545 546 - Fixed DST signal handling in zoneinfo files. Reported by 547 Nicholas F. Fabry and John-Mark Gurney. 548 549 550 Version 1.3 551 =========== 552 553 - Fixed precision problem on conversion of decimal seconds to 554 microseconds, as reported by Skip Montanaro. 555 556 - Fixed bug in constructor of parser, and converted parser classes to 557 new-style classes. Original report and patch by Michael Elsdrfer. 558 559 - Initialize tzid and comps in tz.py, to prevent the code from ever 560 raising a NameError (even with broken files). Johan Dahlin suggested 561 the fix after a pyflakes run. 562 563 - Version is now published in dateutil.__version__, as requested 564 by Darren Dale. 565 566 - All code is compatible with new-style division. 567 568 569 Version 1.2 570 =========== 571 572 - Now tzfile will round timezones to full-minutes if necessary, 573 since Python's datetime doesn't support sub-minute offsets. 574 Thanks to Ilpo Nyyssnen for reporting the issue. 575 576 - Removed bare string exceptions, as reported and fixed by 577 Wilfredo Snchez Vega. 578 579 - Fix bug in leap count parsing (reported and fixed by Eugene Oden). 580 581 582 Version 1.1 583 =========== 584 585 - Fixed rrule byyearday handling. Abramo Bagnara pointed out that 586 RFC2445 allows negative numbers. 587 588 - Fixed --prefix handling in setup.py (by Sidnei da Silva). 589 590 - Now tz.gettz() returns a tzlocal instance when not given any 591 arguments and no other timezone information is found. 592 593 - Updating timezone information to version 2005q. 594 595 596 Version 1.0 597 =========== 598 599 - Fixed parsing of XXhXXm formatted time after day/month/year 600 has been parsed. 601 602 - Added patch by Jeffrey Harris optimizing rrule.__contains__. 603 604 605 Version 0.9 606 =========== 607 608 - Fixed pickling of timezone types, as reported by 609 Andreas Khler. 610 611 - Implemented internal timezone information with binary 612 timezone files [1]. datautil.tz.gettz() function will now 613 try to use the system timezone files, and fallback to 614 the internal versions. It's also possible to ask for 615 the internal versions directly by using 616 dateutil.zoneinfo.gettz(). 617 618 - New tzwin timezone type, allowing access to Windows 619 internal timezones (contributed by Jeffrey Harris). 620 621 - Fixed parsing of unicode date strings. 622 623 - Accept parserinfo instances as the parser constructor 624 parameter, besides parserinfo (sub)classes. 625 626 - Changed weekday to spell the not-set n value as None 627 instead of 0. 628 629 - Fixed other reported bugs. 630 631 [1] http://www.twinsun.com/tz/tz-link.htm 632 633 634 Version 0.5 635 =========== 636 637 - Removed FREQ_ prefix from rrule frequency constants 638 WARNING: this breaks compatibility with previous versions. 639 640 - Fixed rrule.between() for cases where "after" is achieved 641 before even starting, as reported by Andreas Khler. 642 643 - Fixed two digit zero-year parsing (such as 31-Dec-00), as 644 reported by Jim Abramson, and included test case for this. 645 646 - Sort exdate and rdate before iterating over them, so that 647 it's not necessary to sort them before adding to the rruleset, 648 as reported by Nicholas Piper. 649
