v0.2.23

Added

• The documentation was greatly improved for several types, and tons of cross-references have been added. (#77, #78, #80, #82)

• DateTime::timestamp_subsec_{millis,micros,nanos} methods have been added. (#81)

Fixed

• When the system time records a leap second, the nanosecond component was mistakenly reset to zero. (#84)

• Local offset misbehaves in Windows for August and later, due to the long-standing libtime bug (dates back to mid-2015).
  Workaround has been implemented. (#85)

v0.2.22

Fixed

• %.6f and %.9f used to print only three digits when the nanosecond part is zero. (#71)
• The documentation for %+ has been updated to reflect the current status. (#71)

v0.2.21

Fixed

• Fixed::LongWeekdayName was unable to recognize "sunday" (whoops). (#66)

v0.2.20

Changed

• serde dependency has been updated to 0.7. (#63, #64)

v0.2.19

Added

• The documentation for Date is made clear about its ambiguity and guarantees.

Fixed

• DateTime::date had been wrong when the local date and the UTC date is in disagreement. (#61)

v0.2.18

Fixed

• Chrono no longer pulls a superfluous rand dependency. (#57)

v0.2.17

Added

• Naive date and time types and DateTime now have a serde support.
  They serialize as an ISO 8601 / RFC 3339 string just like Debug. (#51)

v0.2.16

Added

• Added %.3f, %.6f and %.9f specifier for formatting fractional seconds up to 3, 6 or 9 decimal digits. This is a natural extension to the existing %f. Note that this is (not yet) generic, no other value of precision is supported. (#45)

• Tons of supporting examples for the documentation have been added. More to come.

Changed

• Forbade unsized types from implementing Datelike and Timelike. This does not make a big harm as any type implementing them should be already sized to be practical, but this change still can break highly generic codes. (#46)

Fixed

• Fixed a broken link in the README.md. (#41)

v0.2.15

Added

• Padding modifiers %_?, %-? and %0? are implemented.
  They are glibc extensions which seem to be reasonably widespread (e.g. Ruby).

• Added %:z specifier and corresponding formatting items which is essentially the same as %z but with a colon.

• Added a new specifier %.f which precision adapts from the input.
  This was added as a response to the UX problems in the original nanosecond specifier %f.

Fixed

• Numeric::Timestamp specifier (%s) was ignoring the time zone offset when provided.

• Improved the documentation and associated tests for strftime.

v0.2.14

• NaiveDateTime +/- Duration or NaiveTime +/- Duration could have gone wrong when the Duration to be added is negative and has a fractional second part.

  This was caused by an underflow in the conversion from Duration to the parts; the lack of tests for this case allowed a bug. (#37)
