⚡️ Data updates
- ⚡️ Updated tzdata version to 2019c.
🛠 Bugfixes
- 🛠 Fixed a race condition in the
tzoffsetandtzstr"strong"
caches on Python 2.7. Reported by @kainjow (gh issue #901). - 📜 Parsing errors will now raise
ParserError, a subclass of
ValueError, which has a nicer string representation. Patch by
@gfyoung (gh pr #881). - 📜
parser.parsewill now raiseTypeErrorwhentzinfosis passed a
type that cannot be interpreted as a time zone. Prior to this

🚀 release. Patch by Hugo van Kemenade (gh pr #950). - ⚡️ Updated many modules to use
tz.UTCin favor oftz.tzutc()
internally, to avoid an unnecessary function call. (gh pr #910). - 🛠 Fixed issue where

environments (such as FreeBSD) due to an invalid assumption about
🛠 what time zone names are provided. Reported and fixed by Kubilay
Kocak (gh issue #918, pr #928). - 🛠 Fixed a minor bug in
test_isoparserrelated tobytes/str
🛠 handling. Fixed by @fhuang5 (gh issue #776, gh pr #879). - 🔧 Explicitly listed all markers used in the pytest configuration. (gh

v2.6.0 Changes
November 08, 2016- ➕ Added PEP-495-compatible methods to address ambiguous and imaginary dates in
time zones in a backwards-compatible way. Ambiguous dates and times can now
be safely represented by all dateutil time zones. Many thanks to Alexander
Belopolski (@abalkin) and Tim Peters @tim-one for their inputs on how to
➕ address this. Original issues reported by Yupeng and @zed (lP: 1390262,
gh issues #57, #112, #249, #284, #286, prs #127, #225, #248, #264, #302). - ➕ Added new methods for working with ambiguous and imaginary dates to the tz
module. datetime_ambiguous() determines if a datetime is ambiguous for a given
zone and datetime_exists() determines if a datetime exists in a given zone.
This works for all fold-aware datetimes, not just those provided by dateutil.
(gh issue #253, gh pr #302) - 🛠 Fixed an issue where dst() in Portugal in 1996 was returning the wrong value
in tz.tzfile objects. Reported by @abalkin (gh issue #128, pr #225) - 🛠 Fixed an issue where zoneinfo.ZoneInfoFile errors were not being properly
deep-copied. (gh issue #226, pr #225) - 🔨 Refactored tzwin and tzrange as a subclass of a common class, tzrangebase, as
there was substantial overlapping functionality. As part of this change,
tzrange and tzstr now expose a transitions() function, which returns the
DST on and off transitions for a given year. (gh issue #260, pr #302) - 🗄 Deprecated zoneinfo.gettz() due to confusion with tz.gettz(), in favor of
get() method of zoneinfo.ZoneInfoFile objects. (gh issue #11, pr #310) - 📜 For non-character, non-stream arguments, parser.parse now raises TypeError
instead of AttributeError. (gh issues #171, #269, pr #247) - 🛠 Fixed an issue where tzfile objects were not properly handling dst() and
tzname() when attached to datetime.time objects. Reported by @ovacephaloid.
(gh issue #292, pr #309) - /usr/share/lib/zoneinfo was added to TZPATHS for compatibility with Solaris
systems. Reported by @dhduvall (gh issue #276, pr #307) - tzoffset and tzrange objects now accept either a number of seconds or a
datetime.timedelta() object wherever previously only a number of seconds was
👍 allowed. (gh pr #264, #277) - datetime.timedelta objects can now be added to relativedelta objects. Reported
and added by Alec Nikolas Reiter (@justanr) (gh issue #282, pr #283 - 🔨 Refactored relativedelta.weekday and rrule.weekday into a common base class
to reduce code duplication. (gh issue #140, pr #311) - An issue where the WKST parameter was improperly rendering in str(rrule) was
🛠 reported and fixed by Daniel LePage (@dplepage). (gh issue #262, pr #263) - A replace() method has been added to rrule objects by @jendas1, which creates
🆕 new rrule with modified attributes, analogous to datetime.replace (gh pr #167) - 🐎 Made some significant performance improvements to rrule objects in Python 2.x
(gh pr #245) - All classes defining equality functions now return NotImplemented when
👍 compared to unsupported classes, rather than raising TypeError, to allow other
👍 classes to provide fallback support. (gh pr #236) - Several classes have been marked as explicitly unhashable to maintain
identical behavior between Python 2 and 3. Submitted by Roy Williams
(@rowillia) (gh pr #296) - 🚚 Trailing whitespace in easter.py has been removed. Submitted by @OmgImAlexis
(gh pr #299) - 🏁 Windows-only batch files in build scripts had line endings switched to CRLF.
(gh pr #237) - 📚 @adamchainz updated the documentation links to reflect that the canonical
location for readthedocs links is now at .io, not .org. (gh pr #272) - 👷 Made some changes to the CI and codecov to test against newer versions of
Python and pypy, and to adjust the code coverage requirements. For the moment,
🚀 full pypy3 compatibility is not supported until a new release is available,
👍 due to upstream bugs in the old version affecting PEP-495 support.
(gh prs #265, #266, #304, #308) - 🖨 The full PGP signing key fingerprint was added to the README.md in favor of
the previously used long-id. Reported by @valholl (gh issue #287, pr #304) - ⚡️ Updated zoneinfo to 2016i. (gh issue #298, gh pr #306)
- ➕ Added PEP-495-compatible methods to address ambiguous and imaginary dates in
