CHANGELOG.md
View File

@ -5,14 +5,17 @@
- Experimental `listOfSpec` delegate.
### Changed
- **API breaking** Config is deprecated, use `ObservableMeta` instead.
- **API breaking** Descriptor no has a member property `defaultValue` instead of `defaultItem()` extension. It caches default value state on the first call. It is done because computing default on each call is too expensive.
- Kotlin 1.5.10
- Build tools 0.10.0
- Relaxed type restriction on `MetaConverter`. Now nullables are available.
### Deprecated
- Direct use of `Config`
### Removed
- Public PluginManager mutability
### Fixed
- Proper json array index treatment
