November 2025 — Kernelkit/infix: RESTCONF service finalization and log cleanup. Implemented RESTCONF Change Logging Cleanup by removing two debug prints from restconf_change in infix-services.c as part of finalizing the RESTCONF service. Reference commit: 10ef03c97179b7a53f3cb354e70f19b479fd9022 (confd: Remove debug prints). No major bugs fixed this month. Overall impact: reduces log noise, improves observability, and supports production readiness of RESTCONF feature.
