Release Notes

chronotope/chrono (chrono)

v0.4.35

Compare Source

Most of our efforts have shifted to improving the API for a 0.5 release, for which cleanups and refactorings are landing on the 0.4.x branch.

The most significant changes in this release are two sets of deprecations.

• We deprecated all timestamp-related methods on NaiveDateTime. The reason is that a timestamp is defined to be in UTC. The NaiveDateTime type doesn't know the offset from UTC, so it was technically wrong to have these methods. The alternative is to use the similar methods on the DateTime<Utc> type, or from the TimeZone trait.

  Converting from NaiveDateTime to DateTime<Utc> is simple with .and_utc(), and in the other direction with .naive_utc().

• The panicking constructors of TimeDelta (the new name of the Duration type) are deprecated. This was the last part of chrono that defaulted to panicking on error, dating from before rust 1.0.

• A nice change is that NaiveDate now includes a niche. So now Option<NaiveDate>, Option<NaiveDateTime> and Option<DateTime<Tz>> are the same size as their base types.

• format::Numeric and format::Fixed are marked as non_exhaustive. This will allow us to improve our formatting and parsing support, and we have reason to believe this breaking change will have little to no impact on users.

v0.4.34: 0.4.34

Compare Source

Notable changes

• In chrono 0.4.34 we finished the work to make all methods const where doing so is supported by rust 1.61.
• We renamed the Duration type to TimeDelta. This removes the confusion between chrono's type and the later Duration type in the standard library. It will remain available under the old name as a type alias for compatibility.
• The Windows implementation of Local is rewritten. The new version avoids panics when the date is outside of the range supported by windows (the years 1601 to 30828), and gives more accurate results during DST transitions.
• The Display format of TimeDelta is modified to conform better to ISO 8601. Previously it converted all values greater than 24 hours to a value with days. This is not correct, as doing so changes the duration from an 'accurate' to a 'nominal' representation to use ISO 8601 terms.

Fixes

• Add missing range check in TimeDelta::milliseconds (#​1385, thanks @​danwilliams)
• Remove check for DurationExceedsTimestamp in DurationRound (#​1403, thanks @​joroKr21)
• Fix localized formatting with %X (https://github.com/chronotope/pure-rust-locales/pull/12, #​1420)
• Windows: base implementation on GetTimeZoneInformationForYear (#​1017)

Additions

• Add TimeDelta::try_milliseconds (#​1385, thanks @​danwilliams)
• Add TimeDelta::new (#​1337)
• Add StrftimeItems::{parse, parse_to_owned} and more documentation (#​1184)
• More standard traits and documentation for format::Locale (via https://github.com/chronotope/pure-rust-locales/pull/8)

Changes

• Rename Duration to TimeDelta, add type alias (#​1406)
• Make TimeDelta methods const (#​1337)
• Make remaining methods of NaiveDate, NaiveWeek, NaiveTime and NaiveDateTime const where possible (#​1337)
• Make methods on DateTime const where possible (#​1400)
• Make Display format of TimeDelta conform better to ISO 8601 (#​1328)

Documentation

• Fix the formatting of timestamp_micros's Example doc (#​1338 via #​1386, thanks @​emikitas)
• Specify branch for GitHub Actions badge and fix link (#​1388)
• Don't mention some deprecated methods in docs (#​1395)
• Remove stray documentation from main (#​1397)
• Improved documentation of TimeDelta constructors (#​1385, thanks @​danwilliams)

Internal

• Switch branch names: 0.4.x releases are the main branch, work on 0.5 happens in the 0.5.x branch (#​1390, #​1402).
• Don't use deprecated method in impl Arbitrary for DateTime and set up CI test (#​1336)
• Remove workaround for Rust < 1.61 (#​1393)
• Bump codecov/codecov-action from 3 to 4 (#​1404)
• Remove partial support for handling -0000 offset (#​1411)
• Move TOO_LONG error out of parse_internal (#​1419)

v0.4.33: 0.4.33

Compare Source

This release fixes the broken docrs.rs build of chrono 0.4.32.

What's Changed

• Make rkyv feature imply size_32 (#​1383)
• Fixed typo in Duration::hours() exception (#​1384, thanks @​danwilliams)

v0.4.32

Compare Source

In this release we shipped part of the effort to reduce the number of methods that could unexpectedly panic, notably for the DateTime and Duration types.

Chrono internally stores the value of a DateTime in UTC, and transparently converts it to the local value as required. For example adding a second to a DateTime needs to be done in UTC to get the correct result, but adding a day needs to be done in local time to be correct. What happens when the value is near the edge of the representable range, and the implicit conversions pushes it beyond the representable range? Many methods could panic on such inputs, including formatting the value for Debug output.

In chrono 0.4.32 the range of NaiveDate, NaiveDateTime and DateTime is made slightly smaller. This allows us to always do the implicit conversion, and in many cases return the expected result. Specifically the range is now from January 1, -262144 until December 31, 262143, one year less on both sides than before. We expect this may trip up tests if you hardcoded the MIN and MAX dates.

Duration had a similar issue. The range of this type was pretty arbitrary picked to match the range of an i64 in milliseconds. Negating an i64::MIN pushes a value out of range, and in the same way negating Duration::MIN could push it out of our defined range and cause a panic. This turns out to be somewhat common and hidden behind many layers of abstraction. We adjusted the type to have a minimum value of -Duration::MAX instead and prevent the panic case.

Other highlights:

• Duration gained new fallible initialization methods.
• Better support for rkyv.
• Most methods on NaiveDateTime are now const.
• We had to bump our MSRV to 1.61 to keep building with our dependencies. This will also allow us to make more methods on DateTime const in a future release.
