First Step

Rationale for Nokia to add LGPL • Make it easier for commercial Increased use users to choose Qt of Qt • Increase Qt Ecosystem – Increase available Qt developer competence – Provide more business opportunities based on Qt Faster pace of • Improve Qt through valuable Larger Qt innovation = feedback and community ecosystem contributions a better Qt

More feedback & contributions

True Open Source project working model

• Development - Source Code management system • Bug Track system • Roadmap

• Git – A distributed revision control system – Used by Qt, Linux, Android, Gnome, Perl… • Gitorious – A web based project host for collaborative open source projects using the Git distributed revision control system – Used by Qt, OpenSuse, MeeGo… • Bring many interesting projects

You can – Find a bug – Report a bug – Keep track of reported bug – Vote a bug • Both external people and Qt developers are working at the same system!

We open our product direction for discussion:

- Public Qt Roadmap - Qt Labs - Blogs - Validation Meetings

Developers can submit patches and Clone Qt on add-ons, or help jointly develop new Gitorious features in Qt Make your modifications
