+ChangeLog for Chrono
+====================
+
+This documents all notable changes to [Chrono](https://github.com/chronotope/chrono).
+
+Chrono obeys the principle of [Semantic Versioning](http://semver.org/), with one caveat: we may
+move previously-existing code behind a feature gate and put it behind a new feature. 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. (@michalsrb #358)
+* Add built-in support for structs with nested `Option<Datetime>` etc fields
+  (@manifest #302)
+
+### Internal/doc improvements
+
+* Use markdown footnotes on the `strftime` docs page (@qudlibetor #359)
+* Migrate from `try!` -> `?` (question mark) because it is now emitting
+  deprecation warnings and has been stable since rustc 1.13.0
+* Deny dead code
+
+## 0.4.9
+
+### Fixes
+
+* Make Datetime arithmatic adjust their offsets after discovering their new
+  timestamps (@quodlibetor #337)
+* Put wasm-bindgen related code and dependencies behind a `wasmbind` feature
+  gate. (@quodlibetor #335)
+
+## 0.4.8
+
+### Fixes
+
+* Add '0' to single-digit days in rfc2822 date format (@wyhaya #323)
+* Correctly pad DelayedFormat (@SamokhinIlya #320)
+
+### Features
+
+* Support `wasm-unknown-unknown` via wasm-bindgen (in addition to
+  emscripten/`wasm-unknown-emscripten`). (finished by @evq in #331, initial
+  work by @jjpe #287)
+
+## 0.4.7
+
+### Fixes
+
+* Disable libc default features so that CI continues to work on rust 1.13
+* Fix panic on negative inputs to timestamp_millis (@cmars #292)
+* Make `LocalResult` `Copy/Eq/Hash`
+
+### Features
+
+* Add `std::convert::From` conversions between the different timezone formats
+  (@mqudsi #271)
+* Add `timestamp_nanos` methods (@jean-airoldie #308)
+* Documentation improvements
+
+## 0.4.6
+
+### Maintenance
+
+* Doc improvements -- improve README CI verification, external links
+* winapi upgrade to 0.3
+
+## Unreleased
+
+### Features
+
+* Added `NaiveDate::from_weekday_of_month{,_opt}` for getting eg. the 2nd Friday of March 2017.
+
+## 0.4.5
+
+### Features
+
+* Added several more serde deserialization helpers (@novacrazy #258)
+* Enabled all features on the playground (@davidtwco #267)
+* Derive `Hash` on `FixedOffset` (@LuoZijun #254)
+* Improved docs (@storyfeet #261, @quodlibetor #252)
+
+## 0.4.4
+
+### Features
+
+* Added support for parsing nanoseconds without the leading dot (@emschwartz #251)
+
+## 0.4.3
+
+### Features
+
+* Added methods to DateTime/NaiveDateTime to present the stored value as a number
+  of nanoseconds since the UNIX epoch (@harkonenbade #247)
+* Added a serde serialise/deserialise module for nanosecond timestamps. (@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)

+* 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`.
