The Liquibase plugin contest is underway and there is still time to submit your extensions. If you are looking for inspriation, there is now an “Ideas Page” on the Extension Portal to get you started.
If you are not planning on creating an extension, but have something that you would like to see created, please add it to the list as well.
Remember, the contest deadline is August 31st and the sooner you submit an entry, the more time you have for feedback to improve it before the contest ends.
