### Added
|
||||
|
||||
### Changed
|
||||
- Simplify inheritance logic in `MutableTypedMeta`
|
||||
|
||||
### Deprecated
|
||||
- MetaProvider `spec` is replaced by `readable`. `listOfSpec` replaced with `listOfReadable`
|
||||
|
||||
### Removed
|
||||
|
||||
### Fixed
|
||||
- Fixed NameToken parsing.
|
||||
- Top level string list meta conversion.
