Version 0.1.2

Major Changes

Import Path Migration

• Updated dependency from brainpy to brainpy.state: Migrated all imports to use the more specific brainpy.state module
  • Updated braintrace/nn/_readout.py: Changed neuron model imports from brainpy to brainpy.state
  • Updated all documentation notebooks (12 files): Concepts, RNN/SNN online learning, batching, state management, and graph visualization tutorials
  • Updated example scripts (4 files): COBA EI RSNN, SNN evaluation, feedforward conv SNN, and SNN models
  • Updated requirements.txt and pyproject.toml to specify brainpy-state as dependency
  • Total: 19 files changed with improved module structure and consistency

New Algorithms

• Added PP-Prop (Pseudo-Prospective Propagation) algorithm: New eligibility trace algorithm in VJP-based methods
  • Added pp_prop to braintrace/_etrace_vjp/esd_rtrl.py
  • Updated docs/apis/algorithms.rst to include PP-Prop in algorithm documentation

Python 3.14 Support

• Added Python 3.14 compatibility: Updated project metadata to officially support Python 3.14
  • Updated pyproject.toml classifiers to include Python 3.14

Bug Fixes

• Fixed version info tuple creation: Corrected the version info structure in braintrace/__init__.py
  • Ensures proper version tuple formatting for compatibility checks

CI/CD Improvements

• Updated GitHub Actions workflow: Bumped actions/upload-artifact from v5 to v6
  • Modernized CI/CD pipeline with latest GitHub Actions versions
  • Improved artifact upload reliability and performance

Documentation Updates

• Updated documentation links: Refreshed links in concept documentation for better navigation
  • Updated docs/quickstart/concepts-en.ipynb (116 lines modified)
  • Updated docs/quickstart/concepts-zh.ipynb (104 lines modified)

Breaking Changes

Dependency Change:

1. Dependency name change: The project now requires brainpy-state instead of brainpy
   • Update your requirements.txt or installation commands accordingly

# Old (0.1.1)
pip install brainpy

# New (0.1.2)
pip install brainpy-state

2. Import path update: Update neuron model imports to use brainpy.state

# New (0.1.2)
from brainpy.state import IF, LIF, ALIF

Migration Guide

Update Dependencies

Replace brainpy with brainpy-state in your project dependencies:

pip uninstall brainpy
pip install brainpy-state

Update Import Statements

If you have custom code importing neuron models, update to use brainpy.state:

# Find and replace in your codebase
# from brainpy import → from brainpy.state import
