-# Recent changes
-
-- 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
-  tools.
--
-- 0.1.0: uses modern kotlin 1.9.*, fixes problem with singleton or empty/object serialization
-
-The last 1.8-based version is 0.0.8. Some fixes are not yet backported to it pls leave an issue of needed.

-    println(mp.pack(mapOf("foo" to 42)).decodeToString())
-    assertEquals("""{"foo":42}""", mp.pack(mapOf("foo" to 42)).decodeToString())
-    val x = mp.unpack<FB1>("""{"foo":42, "bar": "foo"}""".encodeToByteArray())
-    assertEquals(42, x.foo)

-There is also [MotherBipack] `MotherPacker` implementation using Bipack. You can add more formats

 # Bipack
 
 ## Why?
 
 Bipack is a compact and efficient binary serialization library (and format) was designed with the following main goals:
 
-### Allow easy unpacking existing binary structures

 ### Do not reveal information about stored data
 
-Many extendable formats, like JSON, BSON, BOSS and may others are keeping data in key-value pairs. While it is good in many aspects, it has some disadvantages: it uses more space, and it reveals inner data structure to the world. It is possible to unpack such formats with zero information about inner structure.
