### Changed
- **DEPRECATED**.
## [0.8.0] - 2018-04-10
### Changed
- **Breaking**. Use `failure` instead of `error-chain`.
- **Breaking**. A completely new error types.
- Minimum Rust version is 1.18.
## [0.7.0] - 2018-03-11
### Added
- **Breaking**. Added `AttributeValue::Path`.
- **Breaking**. Added `AttributeValue::Points`.
- **Breaking**. Added `AttributeValue::Style`.
- **Breaking**. Added `AttributeValue::Transform`.
- **Breaking**. Added `AttributeValue::ViewBox`.
- **Breaking**. Added `AttributeValue::AspectRatio`.
- `points` attribute tokenizer: `Points`.
- All tokenizers derive `Clone`, `Copy`, `PartialEq` and `Debug` now.
- `Debug` for `NumberList` and `LengthList`.
- Case-insensitive parsing for `rgb(...)` colors.
- `preserveAspectRatio` attribute parsing.
### Changed
- **Breaking**. `AttributeValue` parser no longer return the `points` attribute
as a `NumberList`, but as `Points`.
- **Breaking**. `viewBox` attribute will be parsed as `AttributeValue::ViewBox`
and not as `AttributeValue::NumberList`.
- **Breaking**. `NumberList` and `LengthList` implements `FromSpan` trait
instead of custom `from_span` methods.
- **Breaking**. `TagName` and `AttrName` alias `QName` and not `Name` now.
So tag and attribute names contain namespace prefix now.
But not the namespace URI itself.
- **Breaking**. Prefixed attributes ID's removed. So:
`AttributeId::XlinkHref` -> `xlink` prefix + `AttributeId::Href`.
- **Breaking**. The `cursor` attribute will be parsed as a string now.
- Relicense from MPL-2.0 to MIT/Apache-2.0.
### Fixed

## [0.6.0] - 2017-12-15
**Note:** this update contains a lot of breaking changes.
### Added

### Changed
- XML parsing moved to a separate crate: xmlparser.
- All tokenizer's return `Option<Result<T>>` now and not `Result<T>`.
- `path::Tokenizer` doesn't return errors anymore, because any error should stop parsing anyway.
- Rename `TextFrame` to `StrSpan`.
- Almost all fields in `svg::Token` enum are changed.
### Fixed
- Panic during style attribute parsing.

## [0.5.0] - 2017-09-26

- All \*\_raw methods in `Stream` module are renamed to \*\_unchecked.
- `Stream::parse_number` returns only `InvalidNumber` error now.
- **Breaking change.** All `EndOfStream` tokens are removed.
End of stream is indicated via `Error::EndOfStream` now.
Prefer using a `Tokens` iterator.
