v0.8.0

Highlights

• Lazy iter_range, iter_span_range, and iter_interval APIs with constant auxiliary memory, shared with the existing list APIs.
• Signed nth-weekday shifts through shift_weekday(weekday, nth).
• Local timezone offsets resolved for the target date instead of the Unix epoch.
• Shift argument checks before integer multiplication.

Breaking changes

• Morrow(...) defaults to UTC and validates date/time fields and offsets. Construction and related helpers can raise.
• Create naive values explicitly with tz=TimeZone.none() or .naive().
• Mixed naive/aware equality returns false; ordering, subtraction, relative humanization, and membership checks reject mixed awareness.
• now() and fromtimestamp() continue to use local time.

See the migration guide for details.

Validation and downloads

The supported build matrix covers Mojo 1.0.0 and 1.1.0 on Linux x86-64, Linux ARM64, and macOS ARM64. Select the archive matching your compiler and platform. SHA256SUMS accompanies the archives.

Validation includes 46 tests, seasonal local-time regression tests, and 400 deterministic behavioral checks. English and Chinese documentation builds were also verified.

IANA timezones, explicit DST disambiguation, and localization are planned for 0.9; 0.8 retains fixed-offset timezone values and English text.
