Changelog for version: 2.12.0

This is the change log for the next release of QGIS - version 2.12.0 'Lyon' - host city to our developer meet up in April 2012.

New Features in QGIS 2.12 'Lyon'

This is the next release in our 4-monthly release series. It gives you access to the new features we have been working on and represents the 'cutting edge' of QGIS development.
QGIS 'Lyon' is jam-packed with awesome new features. Special highlights are support for rule based labelling, rule based styling of attribute tables, and advanced geometry checker, support for digitising curve based geometries, better authentication management and much, much more! QGIS 2.12 also has many bug fixes and memory leaks addressed. The features provided in QGIS 2.12 will be included in the next LTR release (slated for release in 2016), so using this release provides you with an excellent opportunity to test new features that will make their way into the next LTR.

Whenever new features are added to software they introduce the possibility of new bugs - if you encounter any problems with this release, please file a ticket on the QGIS Bug Tracker. If you are working in a production environment where you wish to be more conservative about rolling out new features to your users, we also provide a Long Term Release (LTR) version of QGIS. The current LTR is version 2.8.3 and is available at download.qgis.org.

Thanks

We would like to thank the developers, documenters, testers and all the many folks out there who volunteer their time and effort (or fund people to do so).

From the QGIS community we hope you enjoy this release! If you wish to donate time, money or otherwise get involved in making QGIS more awesome, please wander along to qgis.org and lend a hand!

Finally we would like to thank our official sponsors for the invaluable financial support they provide to this project:

A current list of donors who have made financial contributions large and small to the project can be seen on our donors list. If you would like to become and official project sponsor, please visit our sponsorship page for details. Sponsoring QGIS helps us to fund our six monthly developer meetings, maintain project infrastructure
and fund bug fixing efforts.

QGIS is Free software and you are under no obligation to pay anything to use it - in fact we want to encourage people far and wide to use it regardless of what your financial or social status is - we believe empowering people with spatial decision making tools will result in a better society for all of humanity.
