Release Notes

BurntSushi/jiff (jiff)

v0.1.19

Compare Source

===================
This releases includes a UTF-8 related bug fix and a few enhancements.

Firstly, a Span's default Display implementation now writes uppercase
unit designator labels. That means you'll get P1Y2M3DT4H5M6S instead
of P1y2m3dT4h5m6s by default. You can restore previous behavior via
jiff::fmt::temporal::SpanPrinter::lowercase. This change was made to improve
interoperability.

Secondly, SignedDuration now supports rounding via SignedDuration::round.
Note that it only supports rounding time units (hours or smaller). In order to
round with calendar units, you'll still need to use a Span.

Enhancements:

• #​130:
  Document value ranges for methods like year, day, hour and so on.
• #​187:
  Add a rounding API (for time units only) on SignedDuration.
• #​190:
  Span and SignedDuration now use uppercase unit designator labels in their
  default ISO 8601 Display implementation.

Bug fixes:

• #​155:
  Relax strftime format strings from ASCII-only to all of UTF-8.
