Release Notes

BurntSushi/jiff (jiff)

v0.2.9

Compare Source

==================
This release includes a bug fix that, in debug mode, could result in datetime
types having different hashes for the same value. This could cause problems,
for example, if you are using datetimes as keys in a hash map. This problem
didn't exist when Jiff was compiled in release mode.

This release also improves the panic message shown when the js feature isn't
enabled and the current time is requested on wasm32-unknown-unknown targets.

Enhancements:

• #​296:
  Provide a better panic message when Zoned::now() fails on WASM.

Bug fixes:

• #​330:
  Fix bug where Hash on datetime types could yield different hash values for
  the same underlying date/time.

v0.2.8

Compare Source

==================
This release fixes a bug where the constructors on SignedDuration
for floating point durations could panic (in debug mode) or produce
incorrect results (in release mode). This bug only impacts users of
the try_from_secs_{f32,f64} and from_secs_{f32,f64} methods on
SignedDuration.

Enhancements:

• #​326:
  Add an alternate Debug impl for SignedDuration that only shows its second
  and nanosecond components (while using only one component when the other is
  zero).

Bug fixes:

• #​324:
  Fix a bug that could produce a panic or incorrect results in
  SignedDuration::(try_)?from_secs_{f32,f64}.

v0.2.7

Compare Source

==================
This release includes a bug fix that changes how an empty but set TZ
environment variable is interpreted (as indistinguishable from TZ=UTC).
This also includes a new enabled by default create feature, perf-inline,
which allows toggling Jiff's use of inline(always). This may help improve
compile times or decrease binary size.

Enhancements:

• #​320:
  Remove some internal uses of generics to mildly improve compile times.
• #​321:
  Add perf-inline crate feature for controlling inline(always) annotations.

Bug fixes:

• #​311:
  Make TZ= indistinguishable from TZ=UTC.

v0.2.6

Compare Source

==================
This release includes a few bug fixes and support for discovering the IANA Time
Zone Database automatically on Illumos.

Enhancements:

• #​315:
  Add support for automatically finding the tzdb on Illumos.

Bug fixes:

• #​305:
  Fixed Zoned rounding on days with DST time zone transitions.
• #​309:
  Fixed bug where TimeZone::preceding could omit historical time zone
  transitions for time zones that have eliminated DST in the present.
• #​312:
  Fixed nth_weekday_in_month, where it would sometimes incorrectly return an
  error.

v0.2.5

Compare Source

==================
This release updates Jiff's bundled copy of the [IANA Time Zone Database] to
2025b. See the [2025b release announcement][2025b release announcement] for more details.

Enhancements:

• #​300:
  Update jiff-tzdb to 2025b.
