Marco Trevisan, a Canonical Software Engineer and Unity core developer, gave a presentation on Unity. He discussed Unity's codebase, which contains around 175,000 lines of C++ code and sees around 500 commits per month from 90 different developers. Trevisan outlined planned bug fixes and features for the 13.04 release, such as performance improvements and changes to the launcher. He invited attendees to get involved in Unity development by branching the codebase and submitting changes via Bazaar.
