# Changelog
## 0.9.0 - 2021-11-11
### Added
* vcf/record: Add mutable getters for chromosome (`Record::chromosome_mut`),
filters (`Record::filters_mut`), IDs (`Record::ids_mut`), info
(`Record::info_mut`), position (`Record::position_mut`), and quality score
(`Record::quality_score_mut`).
* vcf/record/ids: Add ID wrapper.
* vcf/record/info/field: Add mutable getter for value (`Field::value_mut`).
* vcf/writer: Add common methods to access the underlying writer: `get_mut`
and `into_inner`.
### Changed
* vcf: Update to Rust 2021.
* vcf/header/record/parser: Remove alphanumeric constraint on field keys.
* vcf/record/info: `Info` no longer implements `Deref`.
Use `AsRef<IndexMap<field::Key, Field>>` to access the lower level ordered
map.
* vcf/record/quality_score: Wrap only non-missing values.
The missing quality score state is moved to `vcf::Record` as an `Option`.
### Removed
* vcf/record/filters: Remove missing variant.
`Filters::Missing` is removed in favor of using an `Option` in
`vcf::Record`.
## 0.8.0 - 2021-10-16

genotype (`GT`) fields (`Genotypes::genotypes`) ([#42]).
* vcf/record/genotypes/genotype: Add convenience method to parse the genotype
(`GT`) field (`Genotype::genotype`) ([#42]).
* vcf/record/genotypes/genotype/field/value/genotype: Add conversion from
