# scripting

[holgerbrandl]

Thanks to various contributions from the community, I could polish kscript a bit further, and bumped the version to v2.3. See https://github.com/holgerbrandl/kscript/blob/master/NEWS.md#v23 for the changes.
Most notably users can now derive their own customized kotlin interpreters via https://github.com/holgerbrandl/kscript/blob/master/docs/user_guide.md#create-interpreters-for-custom-dsls
