Aug 1, 2025August 2025 monthly highlights for librenms/librenms: Implemented the Enhanced Alerting Macro System by adding a new Service macro (macros.service) to filter alerts by services that are not disabled or ignored, thereby increasing filtering granularity and reducing alert noise. Extended macro handling to interpret integer macro names ending with '_delta' as integers (consistent with '_perc'), updating the query builder and related documentation. These changes, supported by commits 4010464c3652082ce2c9d4f7bc1a16ca64fbc079 and 007b725377bd54b847fbd2de881eb8d41adfdada, improved alerting accuracy and maintainability. Documentation updates accompany the feature changes.
