 # Changelog
 
+## 2.1.0
+
+* Versions
+  * `Kotlin`: `1.8.22`
+  * `Klock`: `4.0.3`
+* New value class `KrontabConfig`. It is preferable way to create `KronScheduler` instead of
+  `KrontabTemplate` since this update
+* You may configure krontab with builders using simple `KronScheduler` invoke extension
+* New useful extensions like `KronScheduler.daily`
+* `KrontabTemplateWrapper` is obsolete in favor to `KrontabConfig`
+
+## 2.0.0
+
+* Versions
+  * `Kotlin`: `1.8.21`
+  * `Klock`: `4.0.1`
+* Support of `mingwx64` platform
+
+## 1.0.0
+
+* Versions
+  * `Kotlin`: `1.8.20`
+  * `AndroidXWork`: `2.8.1`
+
+## 0.10.0
+
+* New extensions for `KronScheduler`:
+  * `asTzFlowWithoutDelays`/`asFlowWithoutDelays`
+  * `asTzFlowWithDelays`/`asFlowWithDelays`
+* Old `KronScheduler.asFlow` and `KronScheduler.asTzFlow` temporarily marked as deprecated: after several versions their
+behaviour will be changed to undelayed one
+* All the flow extensions now use `cold` non-channel flows. Potentially it should increase performance and decrease memory usage
+
 ## 0.9.0
 
 * Versions
