 # Changes
 
+## 4.0.0
+
+Rewrite by https://github.com/aartiPl 
+
+Improved test_suite.sh
+ * Automatic setting up of test environment (assert.sh, test directories)
+ * Automatic compilation
+ * idea - script to help to test idea use cases
+ * Script setup_environment.sh can be used for local testing
+ * Some script tests moved to Unit Tests
+
+Improved Unit Tests
+* Several new Unit tests
+* New Unit Tests can be created much easier (Major point why modularization makes sense)
+
+Improved Logging
+* Silent mode / Development mode logging
+
+Modularisation of source code
+* Removed duplication
+* Code divided in logical pieces and moved to packages
+* Script resolution creates immutable objects
+            
+
+Build script
+* Updated Gradle to version 7.3 and shadowJar to 6.1.0
+* Fixes in build file
+
+Performance
+* Much less IO operations - that should contribute to better performance
+       
+Misc
+* Updated Kotlin to 1.5.31, but only for compiler, not kotlin-scripting. It's far from optimal, but it is not possible to move fully to Kotlin 1.5 or even 1.6, because of the issues with resolution of artifacts in latest kotlin-scripting. I have put report here: https://youtrack.jetbrains.com/issue/KT-49511
+* Fixed a lot of IDE warnings in code
+* Packaging - gradle file converted to Kotlin; still does not work, but it was like that before anyway
+* Changes for kscript dir allow simple implementation of config file if needed. (.kscript/kscript.config); Not implemented by me, but might be useful e.g. for storing preambles
+
+INCOMPATIBLE CHANGES:
+* In annotations the only allowed delimiter is coma "," (to allow options with arguments, separated by space)
+* Resolution of env variables is more restrictive - only vars expected by kscript can be resolved (for security - it's not good to include arbitrary strings from user env into the script)
+* Reworked caching mechanism
+* Dropped cache for resolution of artifacts - I can not observe change in resolution time. In fact .m2 repository is already kind of cache, so it should not be needed to add another one.

 Release TBD
