March 2025 finished a strong release cycle and enhanced observability across Synapse and Syn2mas, delivering release readiness, risk mitigation, centralized dependency management, and expanded configuration capabilities. Key activities included shipping Synapse release notes for 1.126.0 RC1/RC2 and delivering the stable 1.127.0 release, while reverting a background job that caused increased disk usage to reduce risk. In Syn2mas, telemetry and progress reporting were added via OpenTelemetry, workspace-wide dependency management was centralized with arc-swap, and token expiration visibility was improved with OAuth2 introspection expiration metrics. Documentation updates and configuration improvements accompanied these efforts, along with targeted code cleanup to improve maintainability.
