Is Jira the place to fill the issue?
Or is Github the right one?
Why use two issue tracking?
Jira was the old way of filing issues. I believe they have migrated to GitHub for issue tracking. The Jira is there for historical purposes as this point.
@MattBertolini is right. Liquibase use Github for issue tracking in the community. JIRA use by community has been deprecated and only there for historical.
