Liquibase 2.0 RC5 is now available. It is purely a bug fix for a blocker bug with the ServiceLocator in RC4.
You can download it from http://liquibase.org/download
2.0 RC4 is now available. Like always, you can download it from http://liquibase.org/download.
The main changes in RC4 are improvements to the Maven POM configuration, and a change to how Liquibase classes and extensions are found and loaded.
The 2.0 features and 2.0 upgrade notes are still being added to as well.
As usual, let us know if you have any questions or problems
NOTE: There appears to be a bug, at least in the command line version. I’m looking into it…
2.0 RC3 is now available. Like always, you can download it from http://liquibase.org/download.
RC3 includes:

Wow, it has been a very long time since RC1, but we finally are ready for RC2. It can be downloaded from http://liquibase.org/download like usual, and I have created an ‘upgrade to 2.0 guide“.
There have been a lot of bug fixes between RC1 and RC2 as well as some additional internal code structure and release process work done. The full 2.0 feature list is being built on the wiki at http://liquibase.org/v2_features.
Please test it out and let us know if you have any questions or problems. My goal is for this to be the final RC and to have 2.0 final out in a week or two. The maven plugin is not yet released to the maven repository as I am switching our primary location to Sonatype and that is not fully configured yet. Hopefully in the next couple days it will be available. I will also be working on testing the grails plugin with 2.0 over the next few days and will release an updated version soon.
I was never a huge fan of the upper case B in “LiquiBase” but had gone along with it since that was how it was. However, I’ve decided now that it bugs me too much, and so I am officially changing the product name to “Liquibase” with a lower case B.
I changed some of the documentation and all uses in the code. If you find a documentation page with the old capitalization, please fix it up.
As of the 2.0 release of Liquibase, we will switch to being licensed under the Apache License, version 2.0 rather than the LGPL.
The reason for the change is to make Liquibase more business friendly, especially with regards to being able to write extensions without worrying about license requirements that may be imposed by the LGPL. I’ll work on updating the license information on the web site and in the 2.0 codebase over the next few days. Let me know if you have any questions.
Part of the delay of the next 2.0 RC is that I want that release to include a 2.0 snapshot in the maven repository for people to try. Unfortunately, I have determined that my maven skills are not what I need them to be to make this happen, and am hoping I can get some help.
If you look at the liquibase source from http://liquibase.jira.com/source/browse/CORE you’ll see that we have what is probably an uncommon source configuration–which is the root of a lot of my maven issues.
The main source is broken up into three major sub-modules:
each with its own pom.xml. The general idea is that the liquibase-core and liquibase-core-jvm modules are compiled and combined into a single jar file that is released as liquibase-core.jar while the liquibase-maven-plugin module is released independently. There is a liquibase-dist module that attempts to bind everything together in to liquibase-core, but I’m not sure if it is really doing it all correctly.
Prior to 2.0, liquibase was build using Ant and we do have a repository on sourceforge that is rsynced with the central maven repository. The old process used an ant task to update a local copy of that maven repository and I would upload the new/changed files to the sourceforge site manually.
The main questions that I know of currently are:
Part of the changes made in the upcoming 2.0 release is supporting the ability to specify changelog files in formats other than XML.
As a proof of concept, I added the ability to write your changelog files in specially formatted SQL format rather than XML.
You can now write your changelogs like this:
–liquibase formatted sql
–changeset nvoxland:1
create table test1 (
id int primary key,
name varchar(255)
);–changeset nvoxland:2
insert into test1 (id, name) values (1, ‘name 1′);
insert into test1 (id, name) values (2, ‘name 2′);–changeset nvoxland:3 (dbms:oracle)
create sequence seq_test
which, when run, will run three separate changeSets on oracle, and two changesets on all other databases. Note that this is specifying raw SQL, not abstracted liqubase changes like “createTable” that generate different SQL depending on the target database.
You do need to have your file contain “–liquibase formatted sql” on the first line, and delineate your changelogs with the “–changeset AUTHOR:ID” lines.
After the AUTHOR:ID, you can specify any attribute normally available on the or XML tags, including:
Since the formatted SQL builds the same internal changelog structure as the XML changelogs do, all the normal liquibase functionality (rollback, tag, dbdoc, updateCount, updateSQL, changelog parameters, etc.) are still available.
You can try out this new feature from the current 2.0 snapshot (http://liquibase.org/ci/latest). Let me know if you have any suggestions or problems. I am considering it an early access feature until 2.0 final is released, and there may be changes in the format of this file based on user feedback.
