NEST 2.8.0 is distributed under the GNU General Public License version
2 (or later). This version marks the completion of our development
efforts during the HBP ramp up phase and consists of 290 repository
checkins by 25 developers since 2.6.0. The most notable changes are:

• The new connection framework introduced in NEST 2.6.0 can now handle
  parameter arrays for the ‘all-to-all’ and ‘one-to-one’ rules.
• A new propagator for integrate-and-fire neurons correctly handles
  the case where membrane and synapse time constants are similar or
  the same.
• Better documentation and much extended examples for PyNEST improve
  the discoverability of NEST’s features.

All users are encouraged to upgrade and adapt their simulation scripts
to the changes in the user interface at this point in time to benefit
from the improvements in the new version.

IMPORTANT: some of the defaults in NEST changed. You might have to
adapt your scripts accordingly. See the release notes for details.
