When you compare this release to the previous one, you will see that the changes are more evolutionary, rather than revolutionary.  Even so, there have been a large amount of changes for a minor version increase.  The main focus of the release is once again stability and usability.  We went through a large number of pet-peeves, common mis-understandings and simply solved them, either through new features or by modifying existing ones.  On top of that we worked on the clustering side to make that mode "cloud-ready" with dynamic clustering, making it more solid, adding features too.

Once again, many many thanks go to our large community of Kettle enthusiasts for all the help they provided to make this release another success.

In the i18n department, the overall winners were again the French (Super Samatar Hassan) and Italian (The great Nico Ben) teams.  We've had several contributors compliment them for translating keys (or complete steps that got added) in less than a day!   The Korean (Kim YoungWoo) and Japanese (Hiroyuki Kawaguch) translators continue to do an excellent catch-up job.

Here is an overview of the translation status:

Even though we try our best to re-factor and simplify the codebase all the time, there is no denying that the codebase keeps growing.
Right before every release we run the following command:

find . -name "*.java" -exec wc -l {} \; | awk '{ sum+=$1 } END { print sum }'

This is what that gave us over the last releases:
