Hi Team, I found, that from version 3.0.0, “diffChangeLog” output xml does not include column type differences. But the normal “diff” detects and writes these differences normally in plain text format (not xml). I did some debugging and found that this functionality has been removed (commented out) in liquibase.diff.output.changelog.core.ChangedColumnChangeGenerator class. What is your plan with this issue? I’m currently using 2.0.5, and can’t upgrade without this. Thanks, Zoltan ---

I created [https://liquibase.jira.com/browse/CORE-1433](https://liquibase.jira.com/browse/CORE-1433) to track the re-adding of it. It must have been lost in the code changes going from 2.x to 3.x. I’ll try to get it fixed soon. Nathan ---

Hi, this still seems to be a issue in 3.0.5, even though it is marked “fixed”. As far as I can see, diff still does not create a plain textfile. ---

I’m not quite sure what you mean. Can you give me more information on what you are calling with 3.0.5 and your expected vs. actual results? Nathan ---

Hi Nathan, Thank you for your efforts, now it works again! Zoltán ---

I’m calling the liquibase.integration.ant.DiffDatabaseTask. I expected an output as in 2.0.5 that has the following content: Reference Database: Target Database: Product Name: Product Version: Missing Tables: Unexpected Tables: Missing Views: Unexpected Views: Changed Views: … What I get is a a file with changesets. It is the exact same output as DiffDatabaseToChangeLogTask. ---

Yes, that isn’t right. I fixed it in the code for 3.0.7. Sorry for the bug. Nathan ---

Just tried 3.0.7 and it works perfectly. Thank you for fixing it!
