Issues

• Periodic SpikeGeneratorGroup: set_spikes() after the first period emits a burst of spikes, and can crash

• Cython extension cache key ignores compiler_kwds (include_dirs, macros, sources, …)

• StateMonitor(record=...) with a boolean array records the wrong neurons

  brian-team/brian2#1913 · Filter by author Vaibhaav-Tiwari opened on Oct 30, 2026

• Synaptic indexing: wrong synapses for repeated or negative neuron indices and for the third index, and quadratic cost of S.w[i, :]

• Cython target: a code object that fails to compile is skipped silently, and the simulation "succeeds" without running it

• Regression in 2.10: arrays returned by mon.t[:], S.w[:] etc. can read freed memory (wrong values or crash)
