### Security
## 0.7.0 - 2023-11-26
### Added
- Obligatory `type: KType` and `descriptor` property for `MetaConverters`
- Added separate `Meta`, `SealedMeta` and `ObservableMutableMeta` builders.
### Changed
- Meta converter `metaToObject` returns a non-nullable type. Additional method `metaToObjectOrNull` for nullable return.
- Kotlin 1.9.20.
- Migrated from ktor-io to kotlinx-io.
- `MutableMeta` builder now returns a simplified version of meta that does not hold listeners.
- More concise names for read/write methods in IO.
- Remove unnecessary confusion with `get`/`getMeta` by removing `getMeta` from the interface.
### Deprecated
- `String.parseValue` is replaced with `Value.parse`
### Fixed
- Memory leak in SealedMeta builder
## 0.6.2 - 2023-07-29
### Changed
- Meta to Json serializer now serializes a single item with index as an array. It is important for plotly integration.
- Meta to Json serializes Meta without children a value as literal or array instead of an object with `@value` field.
## 0.6.1 - 2023-03-31
### Added
- File cache for workspace
- Smart task metadata transformation for workspace
- Add `readOnly` property to descriptors
@ -32,6 +58,7 @@
- More fine-grained types in Action builders.
### Changed
- `Name::replaceLast` API
- `PluginFactory` no longer requires plugin class
- Collection<Named> toMap -> associateByName
@ -53,9 +80,11 @@
- Separate interfaces for `IOReader` and `IOWriter`
### Deprecated
- Context.fetch -> Context.request
### Fixed
- `readDataDirectory` does not split names with dots
- Front matter reader does not crash on non-UTF files
- Meta file name in readMeta from directory
@ -64,10 +93,12 @@
## 0.5.2
### Added
- Yaml plugin
- Partial fix to #53
### Fixed
- MutableMetaImpl attachment and checks
- Listeners in observable meta are replaced by lists
- JS number comparison bug.
@ -75,9 +106,11 @@
## 0.5.0
### Added
- 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
@ -88,24 +121,28 @@
- **API breaking** Configurable`config` changed to `meta`
### Removed
- `Config`
- Public PluginManager mutability
- Tables and tables-exposed moved to the separate project `tables.kt`
- BinaryMetaFormat. Use CBOR encoding instead
### Fixed
- Proper json array index treatment.
- Proper json index for single-value array.
## 0.4.0
### Added
- LogManager plugin
- dataforge-context API dependency on SLF4j
- Context `withEnv` and `fetch` methods to manipulate plugins without changing plugins after creation.
- Split `ItemDescriptor` into builder and read-only part
### Changed
- Kotlin-logging moved from common to JVM and JS. Replaced by console for native.
- Package changed to `space.kscience`
- Scheme made observable
@ -115,18 +152,22 @@
- Refactor loggers
### Deprecated
- Direct use of PluginManager
### Removed
- Common dependency on Kotlin-logging
- Kotlinx-io fork dependency. Replaced by Ktor-io.
### Fixed
- Scheme properties properly handle children property change.
## 0.3.0
### Added
- Yaml meta format based on yaml.kt
- `Path` builders
- Special ValueType for lists
@ -134,6 +175,7 @@
- Multiplatform yaml meta
### Changed
- `ListValue` and `DoubleArrayValue` implement `Iterable`.
- Changed the logic of `Value::isList` to check for type instead of size
- `Meta{}` builder made inline
@ -150,6 +192,7 @@
## 0.2.0
### Changed
- Context content resolution refactor
- Kotlin 1.4.10 (build tools 0.6.0)
- Empty query in Name is null instead of ""
@ -159,13 +202,16 @@
- Configurable is no longer MutableItemProvider. All functionality moved to Scheme.
### Deprecated
- Context activation API
