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.
