Dear Colleagues,
Dear NEST users,

We are very happy to announce the final release of NEST 2.0.0. It
is available to you at


This version is the first to be released under the GNU General Public
License version 2 (or later), which replaces the old NEST license.

Thanks to your testing, discussions, feature requests and bug reports,
we were able to fix the a large number of bugs since release candidate 4.
In particular, we changed the following:

* New neuron models: ginzburg_neuron [1] and izhikevich [2]
* New function DataConnect to connect networks based on connectivity data
* New functions GetConnections, GetSynapseStatus and SetSynapseStatus to efficiently query connections
* Fixed regression that restricted the number of neurons connected
* Fixed numerical instabilities of the AdEx model
* Greatly optimized SLI interpreter
* Fixed build failure when compiling with GCC 4.6+
* Tests that use GSL now return success if NEST is compiled
  without GSL support
  to spike_detectors and music_out_proxys to 128
* Fixed typo in Topology User Manual
* Changed license from proprietary NEST License to GNU GPL v2 or later

A complete list of changes, also for previous versions, is available at
the extended changelog on our website at

user mailing list.
