Feb 1, 2026

February 2026 focused on stabilizing the ACP Python integration by upgrading the Agent Commerce Protocol Python SDK to 0.3.20 in Virtual-Protocol/acp-python. The upgrade, driven by bug fixes and improvements in 0.3.20, was applied via two commits (07507dbcc7f3b866e737a1612d46e54689070fbd; eee616fe2e63191a889547e5aba63be481a5f8a8). Thorough validation ensured compatibility and kept downstream consumers unaffected. This work reduces technical debt and improves reliability of commerce transactions for client applications.
