0.7.1

• Date.add and Date.subtract now support DateDelta to be passed as sole positional argument.
• Improved performance and robustness of date calculations at extreme boundaries
• Minor fixes to docstrings

0.7.0

This release adds rounding functionality, along with a small breaking change (see below).

Breaking changes

• TimeDelta.py_timedelta() now truncates nanoseconds to microseconds instead of rounding them. Use the new round() method to customize rounding behavior.

Added

• Added round() to all datetime, Instant, and TimeDelta classes
• Add floor division and modulo operators to TimeDelta
• Add is_ambiguous(), day_length() and start_of_day() to SystemDateTime, for consistency with ZonedDateTime.
• Improvements to documentation

0.6.17

• Added day_length() and start_of_day() methods to ZonedDateTime to make it easier to work with edge cases around DST transitions, and prepare for implementing rounding methods in the future.
• Fix cases in type stubs where positional-only arguments weren't marked as such

0.6.16

• Make disambiguate argument optional in all methods, defaulting to "compatible".
• Fix bug in ZonedDateTime repr() that would mangle some timezone names
• Various small fixes to the docs

0.6.15

• Add Date.days_[since|until] methods for calculating the difference between two dates in days only (no months or years)
• Improve docs about arithmetic rules for calendar and time units.

0.6.14

Fixed

• Ensure docstrings and error messages are consistent in Rust extension as well as the pure-Python version
• Remove undocumented properties hour/minute/etc from Instant that were accidentally left in the Rust extension.
• exact_eq() now also raises TypeError in the pure Python version when comparing different types.

0.6.13

Added

• Make from_py_datetime() methods of Instant/OffsetDateTime less pedantic. They now accept any aware datetime
• New Date.today_in_system_tz() convenience method

Fixed

• Parsing UTC offsets with out-of-range minute/second components (e.g. 06:79) now raises the expected parsing failure.
• Note in parse_rfc2822() docstring that it doesn't (yet) validate the input, due to limitations in the underlying parser.

0.6.12

Fixed format_rfc3339() docs that incorrectly displayed a T separator. Clarified that T can be added by using the format_common_iso() method instead. (#185)

0.6.11

• (new) Added YearMonth and MonthDay classes for working with year-month and month-day pairs
• (fixed) whenever.__version__ is now also accessible when Rust extension is used

0.6.10

Improved

• Improve method documentation and autocomplete support (#172, #173, #176)

Fixed

• Remove lingering undocumented offset on Instant
• Fix incorrect LocalDateTime.difference return type annotation
