   "description": "PyNN (pronounced 'pine') is a simulator-independent language for building neuronal network models.\n\nIn other words, you can write the code for a model once, using the PyNN API and the Python programming language, and then run it without modification on any  simulator that PyNN supports (currently NEURON, NEST and Brian 2) and on a number of neuromorphic hardware systems.\n\nThe PyNN API aims to support modelling at a high-level of abstraction (populations of neurons, layers, columns and the connections between them) while still allowing access to the details of individual neurons and synapses when required. PyNN provides a library of standard neuron, synapse and synaptic plasticity models, which have been verified to work the same on the different supported simulators. PyNN also provides a set of commonly-used connectivity algorithms (e.g. all-to-all, random, distance-dependent, small-world) but makes it easy to provide your own connectivity in a simulator-independent way.\n\nEven if you don't wish to run simulations on multiple simulators, you may benefit from writing your simulation code using PyNN's powerful, high-level interface. In this case, you can use any neuron or synapse model supported by your simulator, and are not restricted to the standard models.",

+=========================
+PyNN 0.13.0 release notes
+=========================
+
+[release date]
+
+Welcome to PyNN 0.13.0!
+
+NESTML support
+--------------
+
+PyNN now supports NESTML_ neuron and synapse models with the NEST_ backend,
+via the new :mod:`pyNN.nest.nestml` module.
+The :func:`nestml_cell_type` and :func:`nestml_synapse_type` factory functions
+allow you to define custom neuron and synapse models in NESTML and use them
+as standard PyNN cell and synapse types, with full support for PyNN's
+:class:`Population` and :class:`Projection` interfaces.
+NESTML compilation is deferred to :func:`sim.setup()` for correct initialisation.
+
+Many thanks to Charl Linssen for co-designing and co-implementing this.
+
+To use NESTML models, install the optional dependency::
+
+    pip install PyNN[nestml]
+
+
+NEURON 9 compatibility
+----------------------
+
+This release includes several fixes for compatibility with NEURON_ 9:
+
+- Fixed extern declarations in :file:`vecstim.mod`.
+- Fixed mod files for the C23 standard (thanks to Ankur Sinha, PR #819).
+- Applied a compatibility patch for random number handling provided by
+  Goran Jelic-Cizmek.
+
+
+NEST 3.10 compatibility
+-----------------------
+
+PyNN now supports NEST_ v3.10.
+
+
+morphio is now optional
+-----------------------
+
+The morphio_ dependency is now optional. It is only required for models
+that use morphologically detailed neuron descriptions. To install with
+morphio support::
+
+    pip install PyNN[morphologies]
+
+
+Python and NumPy version support
+--------------------------------
+
+We have dropped support for Python 3.9.
+Python 3.14 has been added to the test matrix.
+PyNN now works with NumPy 2.x.
+
+
+Bug fixes
+---------
+
+- Fix a floating-point precision issue in pyNN.brian2 that could cause a
+  tiny negative run duration to be computed when resuming a simulation at
+  a time such as 12.7 ms (where floating-point arithmetic leaves the
+  internal time fractionally above the target).
+- Fixed building of Arbor NMODL mechanisms.
+- Fix handling of native Tsodyks synapse types with the NEST backend (issue #810):
+  ``tau_psc`` is now only auto-copied from the post-synaptic neuron for the PyNN
+  standard ``TsodyksMarkramSynapse``, not for ``native_synapse_type``; fixes also
+  applied to ``tau_psc`` reading and inhibitory projection attribute access.
+- Fix :meth:`StepCurrentSource.set_parameters()` when called after :func:`sim.run()`
+  with the NEST backend (issue #759): amplitude times were not adjusted relative to
+  the current biological time, causing NEST to silently ignore the current injection.
+- Fix :class:`ParameterSpace` coercion of lists and arrays to the correct
+  ``ArrayParameter`` subtype (e.g. ``Sequence``), fixing ``SpikeSourceArray``
+  population parameter assignment (issue #709).
