From the NEWS file
 * overall:
  - fix many crashers, including synchronization with openGL, GUI and python
  - generate documentation for both python and c++ classes/functions automatically (http://yade.wikia.com/wiki/Reference_documentation)
  - move away from SVN repository at berlios.de to bzr at http://www.launchpad.net/yade; bug tracking and other launchpad features are being used; mailing lists migrated to launchpad

 * functionality enhancements (apart from performance-oriented changes):
  - Facets (arbitrary triangulation elements) interacting with spheres, allowing to triangulate any surface
  - support for GTS-compatible triangulated surfaces both as predicates and facet-triangulated simulation elements
  - non-incremental sphere-sphere and sphere-facet contact geometry classes (Dem3DofGeom)
  - ConstitutiveLawDispatcher, for having multiple constitutive laws operating on different interactions
  - schedule to run multiple jobs at time, with different parameters (yade-multi, http://yade.wikia.com/wiki/ScriptParametricStudy)
  - added PhysicalParameters::blockedDOFs
  - periodic boundary conditions
  - interaction logic cleaned up
  - sphere packing generators (orthogonal, hexagonal, loose random, triaxially compacted; periodic coming soon)
  - geometry predicates to clip packing, including boolean operations on predicates
  - infrastructure for regression tests

 * performance:
  - consistent openMP support throughout the code (InteractionDispatchers, NewtonsDampedLaw, BexContainer) (http://yade.wikia.com/wiki/Performance_Tuning#openMP)
  - InsertionSortCollider (PersistentSAPCollide removed) (http://yade.wikia.com/wiki/Colliders_performace)
  - InteractionDispatchers that reduce number of loops over interactions to one (http://yade.wikia.com/wiki/Performance_Tuning#InteractionDispatchers)
  - new fast container for interactions (InteractionVecMap) (http://yade.wikia.com/wiki/Performance_Tuning#Containers)
  - caching dispatchers, avoiding repetitive multivirtual call resolution (http://yade.wikia.com/wiki/Performance_Tuning#Dispatcher_cache)
  - runtime profiling information (http://yade.wikia.com/wiki/Speed_profiling_using_TimingInfo_and_TimingDeltas_classes)
  - avoid running collision detection at every step (http://yade.wikia.com/wiki/Insertion_Sort_Collider_Stride)
  - vector and quaternion classes are wrapped in python automatically (faster, avoids hand-written wrappers)
  - removed many python proxy classes, resulting in big speedup of python (e.g. 40 × for some operations)

 * building:
  - yade can be optionally with one single plugin containing all packages. Speeds up full compilation considerably and reduces binary size several times.
  - files in pkg/* are picked up automatically by the build system, including linking flags
  - do not install headers, only plugins
  - fix debian-package builds and document the procedure (http://yade.wikia.com/wiki/DebianPackages), special package for docs
  - fix all (or most) compile-time warnings
  - create new top-level py/ directory for python

 * python:
  - use natural syntax for class instance construction with attributes
  - run telnet server to make yade accessible while running (from localhost only)
  - save any python variables within the XML file, which will be resurrected next time (utils.saveVars, utils.loadVars)
  - support saving simulation to memory temporarily
  - functions from creating video from simulation (via snapshots, either during simulation or in the player)

 * Documentation:
  - Structurized content added http://yade.wikia.com/wiki/Structurized_content
  - FAQ start to implement http://yade.wikia.com/wiki/FAQ
