# Maven Dev Hangout -- April 9th, 2015

## Preparing for Maven 3.3.2

There is a critical issue where core extensions cannot be used from authenticated repos, and an issue with Wagon causing issues for some users trying to stage to Nexus. The core extensions issue has been resolved but I'm looking at the Wagon issue for Jan from the Tycho project.

## Polyglot for Maven

We've done several releases of Polyglot for Maven. The JRuby folks are still working on switching over to Maven 3.3.1
