We run into problems due to name conflicts on implementations of interface liquibase.change.Change. Obviously the names used of the pro version conflict with those of extensions, since the pro implementations are considered with a higher priority.
Since we neither can switch to the pro version nor revised the use of those changes we stick to a version before 3.8.0. If the pro stuff would be shipped in a separate jar, we won't run into these problems. Another solution would we to skip those internal pro implementation if no license is found.
