Changelog

Sourced from jiff's changelog.

0.2.16 (2025-11-07)

This release contains a number of enhancements and bug fixes that have accrued over the last few months. Most are small polishes. A couple of the bug fixes apply to panics that could occur when parsing invalid TZ strings or invalid strptime format strings.

Also, parsing into a Span should now be much faster (for both the ISO 8601 and "friendly" duration formats).

Enhancements:

• #298: Add Serde helpers for (de)serializing std::time::Duration values.
• #396: Add Sub and Add trait implementations for Zoned (in addition to the already existing trait implementations for &Zoned).
• #397: Add BrokenDownTime::set_meridiem and ensure it overrides the hour when formatting.
• #409: Switch dependency on serde to serde_core. This should help speed up compilation times in some cases.
• #430: Add new Zoned::series API, making it consistent with the same API on other datetime types.
• #432: When lenient mode is enabled for strftime, Jiff will no longer error when the formatting string contains invalid UTF-8.
• #432: Formatting of %y and %g no longer fails based on the specific year value.
• #432: Parsing of %s is now a bit more consistent with other fields. Moreover, BrokenDownTime::{to_timestamp,to_zoned} will now prefer timestamps parsed with %s over any other fields that have been parsed.
• #433: Allow parsing just a %s into a Zoned via the Etc/Unknown time zone.

Bug fixes:

• #386: Fix a bug where 2087-12-31T23:00:00Z in the Africa/Casablanca time zone could not be round-tripped (because its offset was calculated incorrectly as a result of not handling "permanent DST" POSIX time zones).
• #407: Fix a panic that occurred when parsing an empty string as a POSIX time zone.
• #410: Fix a panic that could occur when parsing %: via strptime APIs.
• #414: Update some parts of the documentation to indicate that TimeZone::unknown()
