Sourced from time's changelog.

0.3.54 [2026-07-20]

Added

• PrimitiveDateTime has been renamed to PlainDateTime.
• Duration has been renamed to SignedDuration.
• Iteration is now possible over Date, Month, and Weekday. Relevant iterator methods have been overridden to ensure maximum performance.

For both PlainDateTime and SignedDuration, a non-deprecated type alias has been added for backwards compatibility. The new names should be preferred.

Changed

• The associated metadata type (for powerfmt implementations) for various types has been changed to () and made public. This guarantees that no additional metadata will be present.

Performance

• More gains when parsing RFC 2822.

0.3.53 [2026-07-01]

There are no publicly-facing changes in this release. It solely works around the cookie crate relying on an implementation detail of time that was never part of the public API (and thus subject to semver guarantees). The internal API has been reverted to the extent necessary for cookie to compile. This measure is temporary; the internal change will be re-applied in an yet-to-be-determined future release.

0.3.52 [2026-06-30]

Fixed

• Subsecond values in the time! macro are parsed using the textual representation, ensuring accuracy. Previously, they were parsed using the floating point representation, which could result in a loss of precision and even invalid values.
• The date! macro could previously create an invalid value that would then panic at compile time. The macro now emits a proper error instead.
• When parsing an invalid format description, an edge case would inadvertently panic. This now returns an error as intended.

Added

• Support default values when parsing

0.3.51 [2026-06-22]

Fixed

• time compiles with macros enabled. This version is otherwise identical to v0.3.50.
