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.
