Awesome news on the developer branches!

Now if we can just get a configurable webhook so that we can create pull requests through the Looker UI… 😎

edit: nevermind, I think we can do that server side! yeee

@mrosas - is this version available for download yet? The looker-latest.jar link from previous emails still goes to 3.18.15.

@vmdx I’ve messaged you with download instructions for access to an early release.

For any other on premise folks, we update the looker-latest file at the end of the release cycle (~3 weeks after a release date) which will be on May 14, 2015 for 3.20.

Awesome updates! Any chance you guys could add a feature to trigger a specific PDT rebuild on the PDTs admin page?

@mrosas Could we also get access to the early release 3.20? Thanks!
