December 2024 monthly summary for openwallet-foundation/acapy: Fixed Endpoint Refresh Correctness for Attribute Transaction Publication to ensure reliability of attribute publications when routing keys change. This fix updates the endpoint refresh logic to check both endpoint values and routing keys, preventing missed publications caused by stale routing-key information. The change is implemented in commit 6e26d0be40806dd966e724a75f8c7e39c788e549 with message 'fix: check routing keys on endpoint refresh'. Business value: improved data consistency and reliability across distributed agents, reducing publication gaps and follow-up work. Technical impact: reinforced endpoint refresh workflow, improved resilience to routing-key changes, and demonstrated proficiency with Git-based fixes in the openwallet foundation stack.

November 2024 – Security hardening of the verification path in openwallet-foundation/acapy. No new user-facing features this month; instead focused on strengthening input validation and verification method resolution to prevent misinterpretation of proof types. This work reduces the risk of invalid verifications slipping through, improves reliability under edge cases, and lays groundwork for future feature parity with expanded proof type support. Technologies used include Python, pytest-based testing, and secure-by-default verification strategies. Result: improved security posture and maintainability.
