Update command after upgrading from liquibase-core 4.21 to 4.27 shows previously run changelogs

General Discussion

When we upgrade liquibase-core from version 4.21 to 4.27 and run it against our existing database (which is set up with liquibase) it shows all the previously applied changelogs.

There’s been quite a few updates since 4.21. Namely the addition of preConditions. Should I mark all my previous changesets with preCondition MARK_RAN? If not, why are all the previously run changesets showing in my my update command?

public void init() {
    if (Objects.isNull(dataSourceProperties)) {
        throw new RuntimeException("DataSourceProperties is null for databaseName: " + databaseName);
    }
    dataSource = DataSourceBuilder
            .create()
            .url(dataSourceProperties.getUrl())
            .username(dataSourceProperties.getUsername())
            .password(dataSourceProperties.getPassword())
            .build();

    springLiquibase = new ActionableSpringLiquibase();
    springLiquibase.setDataSource(dataSource);
    springLiquibase.setChangeLog(liquibaseProperties.getChangeLog());
    springLiquibase.setContexts(liquibaseProperties.getContexts());
    springLiquibase.setDefaultSchema(liquibaseProperties.getDefaultSchema());
    springLiquibase.setDropFirst(liquibaseProperties.isDropFirst());
    springLiquibase.setShouldRun(liquibaseProperties.isEnabled());
    springLiquibase.setLabelFilter(liquibaseProperties.getLabelFilter());
    springLiquibase.setChangeLogParameters(liquibaseProperties.getParameters());
    springLiquibase.setRollbackFile(liquibaseProperties.getRollbackFile());
}

private Liquibase getLiquibase() throws SQLException, LiquibaseException {
    return springLiquibase.createLiquibase(dataSource.getConnection());
}

public String getUpdateDiff() {
    try (StringWriter out = new StringWriter();
        Liquibase liquibase = this.getLiquibase() ) {
        liquibase.update(new Contexts(), out);
        return out.toString();
    } catch (Exception e) {
        throw new RuntimeException("Unable to get update diff: " + e.getMessage(), e);
    }
}

public class ActionableSpringLiquibase extends DataSourceClosingSpringLiquibase {

public Liquibase createLiquibase(Connection c) throws LiquibaseException {
    return super.createLiquibase(c);
}

}
