We have just released Brian 1.3.1, available via easy_install -U brian or from our download page. This is a minor release, but there are some nice new features and many small improvements (listed below). Minor features:

New PoissonInput class
New auditory model: TanCarney (brian.hears)
Many more examples from papers
New electrode compensation module (in library.electrophysiology)
New trace analysis module (in library.electrophysiology)
Added new brian.tools.taskfarm.run_tasks function to use multiple CPUs to perform multiple runs of a simulation and save results to a DataManager, with an optional GUI interface.
Added FractionalDelay filterbank to brian.hears, fractional itds to HeadlessDatabase and fractional shifts to Sound.shifted.
Added vowel function to brian.hears for creating artificial vowel sounds
New spike_triggered_average function
Added maxlevel and atmaxlevel to Sound
New IRNS/IRNO noise functions

Improvements:

SpikeGeneratorGroup is much faster.
Added RemoteControlClient.set(var, name) to allow sending data to the server from the client (previously you could only receive data from the server but not send it, except in string form).
Monitors do not process empty spike arrays when there have not been any spikes, increases speed for monitored networks with sparse firing (#78)
Various speed optimisations

Bug fixes:

Fixed bug with frozen equations and time variable in equations
Fixed bug with loading sounds using Sound(‘filename.wav’)
SpikeMonitor now clears spiketimes correctly on reinit (#75)
MultiConnection now propagates reinit (important for monitors) (#76)
Fixed bug in realtime plotting
Fixed various bugs in Sound
Fixed bugs in STDP
Now propagates spikes only if spikes exist (#78)
