Oct 1, 2024Month 2024-10: Delivered a developer-experience enhancement in NetLogo/NetLogo by introducing a Persistent Interactive SBT Session. The feature keeps the SBT session open after dependency checks, enabling continuous interaction and the ability to run subsequent commands without restarting the session. This reduces cycle time for builds/tests and accelerates iteration for contributors working on NetLogo/NetLogo.
