Overview ¶
Liquibase package aims to provide a ox plugin to manage migrations with the Liquibase style. That is, using the databasechangelog and databasechangeloglock as well as the xml format for liquibase migrations.
IMPORTANT: This plugin is not ready to be used in production, rather it aims to allow developers to avoid the java and liquibase installation by doing what liquibase does.
