 # Changelog
 
+## 0.3.2
+
+* Add duplication functions for all extensions which allow to send log without tag but with exception and message builder
+
+## 0.3.1
+
+* Technical fixes for compatibility with Java 8
+
+## 0.3.0
+
+* **BREAKING CHANGE**: Filters will not accept message since this update
+* New `KSLog` realization `DefaultKSLog`
+* Now platforms realize their default loggers callbacks instead of `KSLog` factories
+
+## 0.2.0
+
+* Full rewrite of API
+
+## 0.1.1
+
+* Changes in `JVM` levels
+* Fixes in TagLogger
+
+## 0.1.0
+
+* All the platform specific logged factories has been renamed
+
+## 0.0.3
+
+* Fixes in `JVM` logging
+
+## 0.0.2
+
+* New logger `TagLogger` and now extension `Any#logger` will use it to decrease objects allocations
+* Now it is possible to create `KSLog` using any iterable
+* Now it is possible to create `KSLog` using vararg log levels
+
 ## 0.0.1
 
 * Project has been inited

 ### A little bit deeper
 
-There are several important things in context of this library:
+There are several important "terms" in context of this library:
 
-* Default logger (available via `KSLog`)
+* Default logger (available via `KSLog.default`)
 * Local logger (can be created via `KSLog` functions and passed anywhere as `KSLog`)
 * Logging shortcuts like `KSLog.i`/`KSLog.info`
 
+Every logging extension (like `KSLog.i`) have its analog with lazy inited message text and the same one with suffix `S` (like `KSLog.iS`) for the suspendable message calculation.
+
 Default logger can be created by passing `defaultTag` and one of variants log level filters: set or minimal loggable level. In `JVM` you also may setup any logger as base logger for default realizations of `KSLog`. Besides, you may use your own callback (on **any target platform**) as output of logging:
