Release notes

0.2.0

Sponsorship is appreciated!

This is a new semver incompatible release of Jiff. It contains several breaking changes. I expect most users of Jiff to be able to upgrade without any changes. The fundamental API organization of Jiff has not changed.

In case you haven't heard of it before, Jiff is a relatively new datetime library for Rust. Jiff takes enormous inspiration from [Temporal]. Jiff supports automatic and seamless integration with the Time Zone Database, DST aware arithmetic and rounding, formatting and parsing zone aware datetimes losslessly, opt-in Serde support and a whole lot more. Jiff's overall goal is to guide you into the pit of success and make it harder to write buggy code for handling datetimes.

Some of the highlights of this release include reducing footguns and better ecosystem integration.

For reducing footguns, APIs on Span will no longer implicitly assume that days are always 24 hours long. And Span no longer implements PartialEq or Eq (instead favoring span.fieldwise() to create a value that supports naive fieldwise comparison). Moreover, when using TimeZone::system() (perhaps via Zoned::now()), if the system time zone could not be detected, then a special Etc/Unknown time zone will be used instead. This avoids erroring, but also surfaces itself to make it clearer that something has (perhaps) gone wrong.

As for ecosystem integration, this release coincides with the publication of the [jiff-icu], [jiff-sqlx] and [jiff-diesel] crates. jiff-icu integrates with the [ICU4X project], and is now the recommended way to use Jiff to work with non-Gregorian calendars or to localize datetimes for end users. jiff-sqlx and jiff-diesel provide wrapper types that implement the necessary traits to make it ergonomic to store and retrieve Jiff values in a database using [SQLx] or [Diesel], respectively.

Unless something unexpected happens, my plan is for the next breaking change release to be Jiff 1.0 in about 6 months. Once Jiff 1.0 is out, I plan to commit to it indefinitely.

BREAKING CHANGES:

This is an exhaustive list of breaking changes. Changes with the bolded RUNTIME prefix are changes that will not be caught by the Rust compiler. That is, they are changes in runtime behavior.

• #28: The deprecated intz routines on Zoned, Timestamp, civil::DateTime and civil::Date have been removed. You can use in_tz instead. This change was made because many found the name intz to be unclear.
• #32: The PartialEq and Eq trait implementations on Span have been removed.

Changelog

Sourced from jiff's changelog.

0.2.23 (2026-03-03)

This release updates Jiff's bundled copy of the [IANA Time Zone Database] to 2026a. See the 2026a release announcement for more details.

0.2.22 (2026-02-28)

This release includes a bug fix where fallible conversions from signed durations to unsigned durations could panic in some cases.

Bug fixes:

• #526: Fix a panicking bug that occurs for std::time::Duration::try_from(SignedDuration::new(0, -1)).

0.2.21 (2026-02-22)

This release contains a performance improvement and a bug fix for civil::Date::new where it could panic on some inputs.

Bug fixes:

• #523: Fix a bug where Date::new could panic. This was a regression introduced in jiff 0.2.20.

Performance:

• #518: Improve Timestamp to civil::DateTime conversion performance by ~15%.

0.2.20 (2026-02-11)

This release contains a major internal refactor that moves off of using ranged integers internally. There are also some small bug fixes and added support for finding the system time zone on emscripten targets.

Enhancements:

• #11: Stop using ranged integers internally.
• #490: Add support for retrieving the system time zone on emscripten targets.
• #500: Update comparison with the time crate in the Jiff documentation.
