v0.8.1 released!

A 🎄 holiday release! Not much has changed in a month, but we’d like to share it all the same. Notably, the Arbor GUI is co-released as of Arbor v0.8, and v0.8.1 will be no different.

Major new features

• Voltage Processes: add the VOLTAGE_PROCESS mechanism kind to modcc, allowing for direct writing to the membrane voltage (#2033)
• Spack gpu option: added conditional variant for cuda builds to enable GPU-based random number generation (#2043)
• SDE Tutorial (#2044)

Breaking changes since v0.7

• None 💃!

Bug fixed

• Fix ornstein_uhlenbeck example on gpu (#2039)
• Setting ARB_MODCC was broken and nunfunctional. Fixed. (#2029)
• The --cxx flag in arbor-build-catalogue is now properly used; falls back to c++. (#2051)

A full changelog is available in CHANGELOG.md.

The release is out on PyPI, so give it a go:

python -m venv env && source env/bin/activate
pip install arbor
python -c 'import arbor; print(arbor.__config__)'
