# Recent changes
|
||||
|
||||
- 0.1.12 published on all platforms. many small additions.
|
||||
|
||||
- 0.1.11 added interesting collection classes: auto-sorted list with comparator, expirable cache, etc.
|
||||
|
||||
- 0.1.7 built with kotlin 2.0.20 which contains important fix in wasmJS
|
||||
|
||||
- 0.1.6 add many useful features, added support to wasmJS and all other platforms. Note to wasmJS: it appears to be a bug in wasm compiler so BipackDecoder could cause wasm loading problem.
|
||||
|
||||
- 0.1.1: added serialized KVStorage with handy implementation on JVM and JS platforms and some required synchronization

* If this annotation is presented in some @Serializable class definition, its instances

|

* This annotation makes Bipack to insert fields count before the

* serialized data. It then checks it on deserializing to fill not serialized fields will
|

* default values.
|
||||
* __IMPORTANT NOTE__. Since version 0.0.7 it's been also possible to use default values
|
||||
* for non-serialized fields after the end-of-data. If the source reports it correctly, e.g.
|
||||
* [net.sergeych.bintools.DataSource.isEnd] returns true, the unset fields are initialized
|

* with default value. This approach ___is not working when the loading instance is not the last
|

* in the deciding array!___, still it is useful to decode isolated objects. We recommend to
|

* use [Extendable] where needed and possible.
|

*
|

* Note that since 0.0.7 the same behavior could be achieved by serializing each instance in the
|
||||
* array as Bipack correctly processes end-of-data by filling missing fields with default values,
|
||||
* using `Extendable` is more convenient and save some space, most of the time.
|
||||
* Whe deserializing such instances from previous version binaries, the new parameters
|
||||
* will get default values.
|
||||
*
|
||||
* _Please note that without this annotation it could be impossible to deserialize old versions of
|

* the class, in particular, in array, inner fields, etc._
|

* Serialized data of classes not market as ExtendableFormat could not be changed without
|

* breaking compatibility with existing serialized data.
