Changelog

Sourced from jiff's changelog.

0.2.31 (2026-06-29)

This release fixes a minor bug in tests that prevents the crate from running through standard build processes in Linux distributions downstream.

• #594: Fix imports in recently added tests.

0.2.30 (2026-06-29)

This release fixes a safety soundness bug in Jiff's lower level printing APIs. There is also a nice performance improvement to civil::Date::weekday, which also improves downstread routines like civil::Date::nth_weekday and datetime<-->timestamp conversions in some cases.

Enhancements:

• #591: Improve the performance of weekday calculations from Gregorian dates by 30-50%.

Bug fixes:

0.2.29 (2026-06-20)

This release adds support for [defmt], which is a highly efficient logging framework that targets resource-constrained devices, like microcontrollers.

Enhancements:

• #505: Add support for the defmt crate by implementing defmt::Format on the principle public types in Jiff.
• #584: Add Zoned::UNIX_EPOCH as a constant.
• #587: Change the Debug output for civil::ISOWeekDate to match the Debug output style of other primitive datetime types.
