Jan 1, 2026January 2026 monthly summary for deepflow (repo: deepflowio/deepflow). Highlights include three primary feature/quality improvements that align with deployment flexibility and policy governance: 1) Expand YAML configuration capacity in agent_group_configuration by increasing the YAML column size from TEXT to LONGTEXT, updating the DB version, and providing a modification procedure. 2) Introduce configurable ACLController and FUser services with new configuration options, refined Querier structure, and integration into the main config and YAML configuration for better management and deployment flexibility. 3) Define PCAP policy management specifications, establishing maximum limits and complexity thresholds to enhance configuration capabilities and governance. These changes were implemented with targeted commits to support larger configurations, easier deployment, and stronger policy controls.
