This new +feature will always be placed in the `previously-default` feature, which you can use to prevent +breakage if you use `no-default-features`. + +There were/are numerous minor versions before 1.0 due to the language changes. +Versions with only mechanical changes will be omitted from the following list. + +## 0.4.20 (unreleased) + +## 0.4.19 + +* Correct build on solaris/illumos + +## 0.4.18 + +* Restore support for x86_64-fortanix-unknown-sgx + +## 0.4.17 + +* Fix a name resolution error in wasm-bindgen code introduced by removing the dependency on time + v0.1 + +## 0.4.16 + +### Features + +* Add %Z specifier to the `FromStr`, similar to the glibc strptime + (does not set the offset from the timezone name) + +* Drop the dependency on time v0.1, which is deprecated, unless the `oldtime` + feature is active. This feature is active by default in v0.4.16 for backwards + compatibility, but will likely be removed in v0.5. Code that imports + `time::Duration` should be switched to import `chrono::Duration` instead to + avoid breakage. + +## 0.4.15 + +### Fixes + +* Correct usage of vec in specific feature combinations (@quodlibetor) + +## 0.4.14 **YANKED** + +### Features + +* Add day and week iterators for `NaiveDate` (@gnzlbg & @robyoung) +* Add a `Month` enum (@hhamana) +* Add `locales`. All format functions can now use locales, see the documentation for the + `unstable-locales` feature. +* Fix `Local.from_local_datetime` method for wasm + +### Improvements + +* Added MIN and MAX values for `NaiveTime`, `NaiveDateTime` and `DateTime<Utc>`. + +## 0.4.13 + +### Features + +* Add `DurationRound` trait that allows rounding and truncating by `Duration` (@robyoung) + +### Internal Improvements + +* Code improvements to impl `From` for `js_sys` in wasm to reuse code (@schrieveslaach) + +## 0.4.12 + +### New Methods and impls + +* `Duration::abs` to ensure that a duration is just a magnitude (#418 @abreis). + +### Compatibility improvements + +* impl `From` for `js_sys` in wasm (#424 @schrieveslaach) +* Bump required version of `time` for redox support. + +### Bugfixes + +* serde modules do a better job with `Option` types (#417 @mwkroening and #429 + @fx-kirin) +* Use js runtime when using wasmbind to get the local offset (#412 + @quodlibetor) + +### Internal Improvements + +* Migrate to github actions from travis-ci, make the overall CI experience more comprehensible, + significantly faster and more correct (#439 @quodlibetor) + +## 0.4.11 + +### Improvements + +* Support a space or `T` in `FromStr` for `DateTime<Tz>`, meaning that e.g. + `dt.to_string().parse::<DateTime<Utc>>()` now correctly works on round-trip. + (@quodlibetor in #378) +* Support "negative UTC" in `parse_from_rfc2822` (@quodlibetor #368 reported in + #102) +* Support comparisons of DateTimes with different timezones (@dlalic in #375) +* Many documentation improvements + +### Bitrot and external integration fixes + +* Don't use wasmbind on wasi (@coolreader18 #365) +* Avoid deprecation warnings for `Error::description` (@AnderEnder and + @quodlibetor #376) + +### Internal improvements + +* Use Criterion for benchmarks (@quodlibetor) + +## 0.4.10 + +### Compatibility notes + +* Putting some functionality behind an `alloc` feature to improve no-std + support (in #341) means that if you were relying on chrono with + `no-default-features` *and* using any of the functions that require alloc + support (i.e. any of the string-generating functions like `to_rfc3339`) you + will need to add the `alloc` feature in your Cargo.toml. + +### Improvements + +* `DateTime::parse_from_str` is more than 2x faster in some cases. (@michalsrb + #358) +* Significant improvements to no-std and alloc support (This should also make + many format/serialization operations induce zero unnecessary allocations) + (@CryZe #341) + +### Features + +* Functions that were accepting `Iterator` of `Item`s (for example + `format_with_items`) now accept `Iterator` of `Borrow<Item>`, so one can + use values or references.

(@harkonenbade #247) +* Added "Permissive" timezone parsing which allows a numeric timezone to + be specified without minutes. (@quodlibetor #242) + +## 0.4.2 + +### Deprecations + +* More strongly deprecate RustcSerialize: remove it from documentation unless + the feature is enabled, issue a deprecation warning if the rustc-serialize + feature is enabled (@quodlibetor #174) + +### Features + +* Move all uses of the system clock behind a `clock` feature, for use in + environments where we don't have access to the current time. (@jethrogb #236) +* Implement subtraction of two `Date`s, `Time`s, or `DateTime`s, returning a + `Duration` (@tobz1000 #237) + +## 0.4.1 + +### Bug Fixes + +* Allow parsing timestamps with subsecond precision (@jonasbb) +* RFC2822 allows times to not include the second (@upsuper) + +### Features + +* New `timestamp_millis` method on `DateTime` and `NaiveDateTim` that returns + number of milliseconds since the epoch. (@quodlibetor) +* Support exact decimal width on subsecond display for RFC3339 via a new + `to_rfc3339_opts` method on `DateTime` (@dekellum) +* Use no_std-compatible num dependencies (@cuviper) +* Add `SubsecRound` trait that allows rounding to the nearest second + (@dekellum) + +### Code Hygiene and Docs + +* Docs! (@alatiera @kosta @quodlibetor @kennytm) +* Run clippy and various fixes (@quodlibetor) + +## 0.4.0 (2017-06-22) + +This was originally planned as a minor release but was pushed to a major +release due to the compatibility concern raised. + +### Added + +- `IsoWeek` has been added for the ISO week without time zone. + +- The `+=` and `-=` operators against `time::Duration` are now supported for + `NaiveDate`, `NaiveTime` and `NaiveDateTime`. (#99) + + (Note that this does not invalidate the eventual deprecation of `time::Duration`.) + +- `SystemTime` and `DateTime<Tz>` types can be now converted to each other via `From`. + Due to the obvious lack of time zone information in `SystemTime`, + the forward direction is limited to `DateTime<Utc>` and `DateTime<Local>` only. + +### Changed + +- Intermediate implementation modules have been flattened (#161), + and `UTC` has been renamed to `Utc` in accordance with the current convention (#148). + + The full list of changes is as follows: + + Before | After + ---------------------------------------- | ---------------------------- + `chrono::date::Date` | `chrono::Date` + `chrono::date::MIN` | `chrono::MIN_DATE` + `chrono::date::MAX` | `chrono::MAX_DATE` + `chrono::datetime::DateTime` | `chrono::DateTime` + `chrono::naive::time::NaiveTime` | `chrono::naive::NaiveTime` + `chrono::naive::date::NaiveDate` | `chrono::naive::NaiveDate` + `chrono::naive::date::MIN` | `chrono::naive::MIN_DATE` + `chrono::naive::date::MAX` | `chrono::naive::MAX_DATE` + `chrono::naive::datetime::NaiveDateTime` | `chrono::naive::NaiveDateTime` + `chrono::offset::utc::UTC` | `chrono::offset::Utc` + `chrono::offset::fixed::FixedOffset` | `chrono::offset::FixedOffset` + `chrono::offset::local::Local` | `chrono::offset::Local` + `chrono::format::parsed::Parsed` | `chrono::format::Parsed` + + With an exception of `Utc`, this change does not affect any direct usage of + `chrono::*` or `chrono::prelude::*` types. + +- `Datelike::isoweekdate` is replaced by `Datelike::iso_week` which only returns the ISO week. + + The original method used to return a tuple of year number, week number and day of the week, + but this duplicated the `Datelike::weekday` method and it had been hard to deal with + the raw year and week number for the ISO week date. + This change isolates any logic and API for the week date into a separate type. + +- `NaiveDateTime` and `DateTime` can now be deserialized from an integral UNIX timestamp. (#125) + + This turns out to be very common input for web-related usages. + The existing string representation is still supported as well. + +- `chrono::serde` and `chrono::naive::serde` modules have been added + for the serialization utilities. (#125) + + Currently they contain the `ts_seconds` modules that can be used to + serialize `NaiveDateTime` and `DateTime` values into an integral UNIX timestamp. + This can be combined with Serde's `[de]serialize_with` attributes + to fully support the (de)serialization to/from the timestamp. + + For rustc-serialize, there are separate `chrono::TsSeconds` and `chrono::naive::TsSeconds` types + that are newtype wrappers implementing different (de)serialization logics. + This is a suboptimal API, however, and it is strongly recommended to migrate to Serde. + +### Fixed + +- The major version was made to fix the broken Serde dependency issues. (#146, #156, #158, #159) + + The original intention to technically break the dependency was + to facilitate the use of Serde 1.0 at the expense of temporary breakage. + Whether this was appropriate or not is quite debatable, + but it became clear that there are several high-profile crates requiring Serde 0.9 + and it is not feasible to force them to use Serde 1.0 anyway. + + To the end, the new major release was made with some known lower-priority breaking changes. + 0.3.1 is now yanked and any remaining 0.3 users can safely roll back to 0.3.0. + +- Various documentation fixes and goodies. (#92, #131, #136) + +## 0.3.1 (2017-05-02) + +### Added + +- `Weekday` now implements `FromStr`, `Serialize` and `Deserialize`. (#113) + + The syntax is identical to `%A`, i.e. either the shortest or the longest form of English names. + +### Changed + +- Serde 1.0 is now supported. (#142) + + This is technically a breaking change because Serde 0.9 and 1.0 are not compatible, + but this time we decided not to issue a minor version because + we have already seen Serde 0.8 and 0.9 compatibility problems even after 0.3.0 and + a new minor version turned out to be not very helpful for this kind of issues. + +### Fixed + +- Fixed a bug that the leap second can be mapped wrongly in the local time zone. + Only occurs when the local time zone is behind UTC. (#130) + +## 0.3.0 (2017-02-07) + +The project has moved to the [Chronotope](https://github.com/chronotope/) organization. + +### Added + +- `chrono::prelude` module has been added. All other glob imports are now discouraged. + +- `FixedOffset` can be added to or subtracted from any timelike types. + + - `FixedOffset::local_minus_utc` and `FixedOffset::utc_minus_local` methods have been added. + Note that the old `Offset::local_minus_utc` method is gone; see below. + +- Serde support for non-self-describing formats like Bincode is added. (#89) + +- Added `Item::Owned{Literal,Space}` variants for owned formatting items. (#76) + +- Formatting items and the `Parsed` type have been slightly adjusted so that + they can be internally extended without breaking any compatibility. + +- `Weekday` is now `Hash`able. (#109) + +- `ParseError` now implements `Eq` as well as `PartialEq`. (#114) + +- More documentation improvements. (#101, #108, #112) + +### Changed + +- Chrono now only supports Rust 1.13.0 or later (previously: Rust 1.8.0 or later). + +- Serde 0.9 is now supported. + Due to the API difference, support for 0.8 or older is discontinued. (#122) + +- Rustc-serialize implementations are now on par with corresponding Serde implementations. + They both standardize on the `std::fmt::Debug` textual output. + + **This is a silent breaking change (hopefully the last though).** + You should be prepared for the format change if you depended on rustc-serialize. + +- `Offset::local_minus_utc` is now `Offset::fix`, and returns `FixedOffset` instead of a duration. + + This makes every time zone operation operate within a bias less than one day, + and vastly simplifies many logics. + +- `chrono::format::format` now receives `FixedOffset` instead of `time::Duration`. + +- The following methods and implementations have been renamed and older names have been *removed*. + The older names will be reused for the same methods with `std::time::Duration` in the future. + + - `checked_*` → `checked_*_signed` in `Date`, `DateTime`, `NaiveDate` and `NaiveDateTime` types + + - `overflowing_*` → `overflowing_*_signed` in the `NaiveTime` type + + - All subtraction implementations between two time instants have been moved to + `signed_duration_since`, following the naming in `std::time`. + +### Fixed + +- Fixed a panic when the `Local` offset receives a leap second. (#123) + +### Removed + +- Rustc-serialize support for `Date<Tz>` types and all offset types has been dropped. + + These implementations were automatically derived and never had been in a good shape. + Moreover there are no corresponding Serde implementations, limiting their usefulness. + In the future they may be revived with more complete implementations. + +- The following method aliases deprecated in the 0.2 branch have been removed. + + - `DateTime::num_seconds_from_unix_epoch` (→ `DateTime::timestamp`) + - `NaiveDateTime::from_num_seconds_from_unix_epoch` (→ `NaiveDateTime::from_timestamp`) + - `NaiveDateTime::from_num_seconds_from_unix_epoch_opt` (→ `NaiveDateTime::from_timestamp_opt`) + - `NaiveDateTime::num_seconds_unix_epoch` (→ `NaiveDateTime::timestamp`) + +- Formatting items are no longer `Copy`, except for `chrono::format::Pad`. + +- `chrono::offset::add_with_leapsecond` has been removed. + Use a direct addition with `FixedOffset` instead. + +## 0.2.25 (2016-08-04) + +This is the last version officially supports Rust 1.12.0 or older. + +(0.2.24 was accidentally uploaded without a proper check for warnings in the default state, +and replaced by 0.2.25 very shortly. Duh.) + +### Added + +- Serde 0.8 is now supported. 0.7 also remains supported. (#86) + +### Fixed + +- The deserialization implementation for rustc-serialize now properly verifies the input. + All serialization codes are also now thoroughly tested. (#42) + +## 0.2.23 (2016-08-03) + +### 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) + +## 0.2.22 (2016-04-22) + +### 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) + +## 0.2.21 (2016-03-29) + +### Fixed + +- `Fixed::LongWeekdayName` was unable to recognize `"sunday"` (whoops). (#66) + +## 0.2.20 (2016-03-06) + +### Changed + +- `serde` dependency has been updated to 0.7. (#63, #64) + +## 0.2.19 (2016-02-05) + +### 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) + +## 0.2.18 (2016-01-23) + +### Fixed + +- Chrono no longer pulls a superfluous `rand` dependency. (#57) + +## 0.2.17 (2015-11-22) + +### 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) + +## 0.2.16 (2015-09-06) + +### 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) + +### 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) + +## 0.2.15 (2015-07-05) + +### 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`. + +## 0.2.14 (2015-05-15) + +### 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. (#37) + +## 0.2.13 (2015-04-29) + +### Added + +- The optional dependency on `rustc_serialize` and + relevant `Rustc{En,De}codable` implementations for supported types has been added. + This is enabled by the `rustc-serialize` Cargo feature. (#34) + +### Changed + +- `chrono::Duration` reexport is changed to that of crates.io `time` crate. + This enables Rust 1.0 beta compatibility. + +## 0.2.4 (2015-03-03) + +### Fixed + +- Clarified the meaning of `Date<Tz>` and fixed unwanted conversion problem + that only occurs with positive UTC offsets. (#27) + +## 0.2.3 (2015-02-27) + +### Added + +- `DateTime<Tz>` and `Date<Tz>` is now `Copy`/`Send` when `Tz::Offset` is `Copy`/`Send`. + The implementations for them were mistakenly omitted. (#25) + +### Fixed + +- `Local::from_utc_datetime` didn't set a correct offset. (#26) + +## 0.2.1 (2015-02-21) + +### Changed + +- `DelayedFormat` no longer conveys a redundant lifetime. + +## 0.2.0 (2015-02-19) + +### Added + +- `Offset` is splitted into `TimeZone` (constructor) and `Offset` (storage) types. + You would normally see only the former, as the latter is mostly an implementation detail. + Most importantly, `Local` now can be used to directly construct timezone-aware values. + + Some types (currently, `UTC` and `FixedOffset`) are both `TimeZone` and `Offset`, + but others aren't (e.g. `Local` is not what is being stored to each `DateTime` values). + +- `LocalResult::map` convenience method has been added. + +- `TimeZone` now allows a construction of `DateTime` values from UNIX timestamp, + via `timestamp` and `timestamp_opt` methods. + +- `TimeZone` now also has a method for parsing `DateTime`, namely `datetime_from_str`. + +- The following methods have been added to all date and time types: + + - `checked_add` + - `checked_sub` + - `format_with_items` + +- The following methods have been added to all timezone-aware types: + + - `timezone` + - `with_timezone` + - `naive_utc` + - `naive_local` + +- `parse_from_str` method has been added to all naive types and `DateTime<FixedOffset>`. + +- All naive types and instances of `DateTime` with time zones `UTC`, `Local` and `FixedOffset` + implement the `FromStr` trait. They parse what `std::fmt::Debug` would print. + +- `chrono::format` has been greatly rewritten. + + - The formatting syntax parser is modular now, available at `chrono::format::strftime`. + + - The parser and resolution algorithm is also modular, the former is available at + `chrono::format::parse` while the latter is available at `chrono::format::parsed`. + + - Explicit support for RFC 2822 and 3339 syntaxes is landed. + + - There is a minor formatting difference with atypical values, + e.g. for years not between 1 BCE and 9999 CE. + +### Changed + +- Most uses of `Offset` are converted to `TimeZone`. + In fact, *all* user-facing code is expected to be `Offset`-free. + +- `[Naive]DateTime::*num_seconds_from_unix_epoch*` methods have been renamed to + simply `timestamp` or `from_timestamp*`. The original names have been deprecated. + +### Removed + +- `Time` has been removed. This also prompts a related set of methods in `TimeZone`. + + This is in principle possible, but in practice has seen a little use + because it can only be meaningfully constructed via an existing `DateTime` value. + This made many operations to `Time` unintuitive or ambiguous, + so we simply let it go. + + In the case that `Time` is really required, one can use a simpler `NaiveTime`. + `NaiveTime` and `NaiveDate` can be freely combined and splitted, + and `TimeZone::from_{local,utc}_datetime` can be used to convert from/to the local time. + +- `with_offset` method has been removed. Use `with_timezone` method instead. + (This is not deprecated since it is an integral part of offset reform.) + +## 0.1.14 (2015-01-10) + +### Added + +- Added a missing `std::fmt::String` impl for `Local`. + +## 0.1.13 (2015-01-10) + +### Changed + +- Most types now implement both `std::fmt::Show` and `std::fmt::String`, + with the former used for the stricter output and the latter used for more casual output. + +### Removed + +- `Offset::name` has been replaced by a `std::fmt::String` implementation to `Offset`. + +## 0.1.12 (2015-01-08) + +### Removed + +- `Duration + T` no longer works due to the updated impl reachability rules. + Use `T + Duration` as a workaround. + +## 0.1.4 (2014-12-13) + +### Fixed + +- Fixed a bug that `Date::and_*` methods with an offset that can change the date are + off by one day. + +## 0.1.3 (2014-11-28) + +### Added + +- `{Date,Time,DateTime}::with_offset` methods have been added. + +- `LocalResult` now implements a common set of traits. + +- `LocalResult::and_*` methods have been added. + They are useful for safely chaining `LocalResult<Date<Off>>` methods + to make `LocalResult<DateTime<Off>>`. + +### Changed + +- `Offset::name` now returns `SendStr`. + +- `{Date,Time} - Duration` overloadings are now allowed. + +## 0.1.2 (2014-11-24) + +### Added + +- `Duration + Date` overloading is now allowed. + +### Changed + +- Chrono no longer needs `num` dependency. + +## 0.1.0 (2014-11-20) + +The initial version that was available to `crates.io`. + |
