0.6.6

Fix potential memory leak in .now() if time-machine is used

0.6.5

• from_timestamp now also accepts floats, to ease porting code from datetime (#159)
• Fixed incorrect fractional seconds when parsing negative values in from_timestamp methods.
• Fix some places where ValueError was raised instead of TypeError

0.6.4

• Add helper patch_current_time for patching current time in whenever (only) (#147)
• Support patching the current time with time-machine (#147)
• Remove undocumented year/month/day/offset properties from Instant
• Reduce size of binary distributions
• Clarify contribution guidelines

0.6.3

• Improve robustness and speed of keyword argument parsing in Rust extension (#149)
• Add more answers to common questions in the docs and FAQ (#148, #150)

0.6.2

Add third-party licenses to distributions

0.6.1

Small updates to project metadata

0.6.0

🎉 A big release touting a Rust extension module and an API more consistent with other modern libraries.

Added or improved

• Implement as a Rust extension module, leading to a big speedup
• Add replace_date and replace_time methods to datetimes.
• Add Date.MIN and Date.MAX constants.
• from_py_* methods are more robust.
• The pickle format for most types is now more efficient.

Breaking changes

(see the changelog for the full rationale behind each change)

• UTCDateTime is now Instant. Removed methods that were specific to UTC.
• NaiveDateTime is now LocalDateTime
• Nanosecond precision is now the default for all datetimes and deltas. nanosecond is a keyword-only argument for all constructors, to prevent mistakes porting code from datetime (which uses microseconds).
• Unified [from_]canonical_format methods with [from_]common_iso8601 methods into [format|parse]_common_iso methods.
• Timestamp methods now use integers instead of floats. There are now separate methods for seconds, milliseconds, and nanoseconds.
• Renamed [from_][rfc3339|rfc2822] methods to [format|parse]_[rfc3339|rfc2822].
• Added explicit ignore_dst=True flag to DST-unsafe operations such as shifting an offset datetime.
• Renamed as_utc, as_offset, as_zoned, as_local to to_utc, to_fixed_offset, to_tz, to_system_tz, and the NaiveDateTime.assume_* methods accordingly
• disambiguate= is non-optional for all relevant methods. The only exception is the constructor, which defaults to "raise".
• Removed weakref support.
• Weekdays are now an enum instead of an integer.
• Calendar units in Date[Time]Delta can now only be retrieved together. For example, there is no delta.months or delta.days anymore,delta.in_months_days() should be used in this case.
• Units in delta cannot be different signs anymore (after normalization).
• Calendar units are normalized, but only in so far as they can be converted strictly. For example, 1 year is always equal to 12 months, but 1 month isn't equal to a fixed number of days. Refer to the delta docs for more information.
• Renamed AmbiguousTime to RepeatedTime.
• Dropped Python 3.8 support

0.5.2

Add Date.py_date() (#118)

0.5.1

Fix LocalSystemDateTime.now() not setting the correct offset (#104)

0.5.0

Breaking changes

• Fix handling of -0000 offset in RFC2822 format, which was not according to the standard. NaiveDateTime can now no longer be created from this format.
• DateDelta canonical format now uses P prefix.

Improved

• Add explicit ISO8601 formatting/parsing methods to datetimes, date, time, and deltas.
• Add missing Date.from_canonical_format method.
• Separate docs for deltas and datetimes.
• NaiveDateTime.assume_offset now also accepts integers as hour offsets.
