## [v0.11.2] - 2020-09-04
[v0.11.2]: https://github.com/fastobo/fastobo/compare/v0.11.1...v0.11.2
### Fixed

## [v0.11.1] - 2020-08-31
[v0.11.1]: https://github.com/fastobo/fastobo/compare/v0.11.0...v0.11.1
### Changed
- Comparison order of entity frames for consistency with the OBO 1.4
[serializer conventions](https://owlcollab.github.io/oboformat/doc/GO.format.obo-1_4.html#S.3.5).
## [v0.11.0] - 2020-08-29
[v0.11.0]: https://github.com/fastobo/fastobo/compare/v0.10.0...v0.11.0
### Added
- Derived `Default` implementation for `QuotedString` and `UnquotedString` types.

`fastobo::ast::ResourcePropertyValue` and `fastobo::ast::LiteralPropertyValue`.
- `Definition` struct to store text and xrefs of a definition clause.

to get the definition of an entity frame if it is unique.
### Changed

for literal property values instead of XML Schema ones previously.
- Made some optional fields of structs heap-allocated to further reduce memory
consumption.

in the dependencies and greatly increasing build time.
