0.3.0: Planned breaking changes to the existing interface.

So this is a much delayed major release, but this should not really
change how you use Chrono---only the "required" breakages have been
done (e.g. anything hindering API evolution). The "big" release used to
be 0.3, but due to the dependency changes we are forced to push that to
0.4. I've took this opportunity to push all known planned breaking
changes to 0.3, so this should be quite stable for a moment.

See `CHANGELOG.md` for the full list of changes, but most importantly:

- `chrono::prelude` module has been added for proper glob imports.

- `FixedOffset` is now the official "value" type for time zone offsets.

- Serde 0.9 support has landed, and serialization format used by
  rustc-serialize and Serde has been now synchronized.

- Formatting items have been slightly adjusted to be future-proof.

Fixes #126.

+## 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.)
