Abstract: v0.10.0 (08.08.2024) Major Changes since v0.9.0 Automatic network generation from high-level specifications. Units at the user interface including scaling and conversion. Morphologies are loaded through a unified interface; which produces a bundle of morphology, metadata, and segment tree. Internal Updates Documentation overhaul Python bindings offer type stubs; giving auto-completion and inline documentation in some editors/IDEs. Performance improvements Label resolution uses hashes instead of strings, saving memory, network traffic, and time. Spike delivery is up to 30% faster leading to 10% end-to-end improvements in some cases (e.g. example/brunel) Load balancing is faster and doesn't rely on MPI, leading to shorter setup times for large networks. Fixes Better support for source builds on MacOS (aarch64) modcc no longer allows internal variables (v, celsius, ...) as ASSIGNED Better support for raw (C++) mechanisms MC cells renamed cable cells. Breaking changes Return values of all morphology loaders have changed. Raw (segment tree) loaders removed. Support for Python 3.8 removed. C++: Removed simulation::inject_events, use a generator instead.
