- Tons of documentation updates! (#77, #78, #80, #82 and my own
changes as well)
- `DateTime::timestamp_subsec_{millis,micros,nanos}` methods have
been added. (#81)
- 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)
- `%.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)
- 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)
- 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 a broken link in the `README.md`. (#41)
- Tons of supporting examples for the documentation have been added. More to come.
- Added padding modifiers `%_?`, `%-?` and `%0?`.
- Added new specifiers `%:z` and `%.f`.
- When `%s` specifier is used with a time zone, the time zone offset was
ignored. This has been fixed.
- Several documentation fixes including the misleading presence of
colons in the `%z` specifier. `%:z` was introduced partly due to this.
- The time zone offset is printed without a colon, but the documentation
had that inverted. (#39)
- `chrono::format::strftime`'s specifier table is tested throughly.
- When `%s` specifier is used with a time zone, the time zone offset was
ignored. This has been fixed.
- `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.
A regression test has been added to avoid further bugs. (#37)
- This version is finally beta-compatible.
This introduces a slight incompatibility, namely, due to
the rewired reexport for `chrono::Duration` (which now comes
from crates.io `time` crate).
- The optional dependency on `rustc_serialize` and relevant
`Rustc{En,De}codable` implementations for supported types
has been added. You will need the `rustc-serialize` Cargo
feature to use them.
- `DateTime<Tz>` and `Date<Tz>` is now `Copy`/`Send` when
`Tz::Offset` is `Copy`/`Send`. The implementations for them were
mistakenly omitted. Fixes#25.
- `Local::from_utc_datetime` didn't set a correct offset.
The tests for `Local` were lacking. Fixes#26.
