Oct 1, 2025October 2025 highlights for element-hq/synapse focused on security, reliability, and admin API capabilities. Key outcomes include security patches addressing a device key validation CVE and MSC2732 deprecation, robust handling of null device_keys in keys uploads, and documentation improvements to surface the Fetch Event in Admin API docs. A major Admin API release stream (1.140.0rc1/1.141.0rc1) delivered enhanced media/event querying, policy server improvements, and compatibility updates, supported by updated release notes and changelog. Impact: reduced security risk, eliminated 500s on key uploads, better admin tooling and discoverability, and groundwork for future platform evolution.

Sep 1, 2025September 2025 monthly summary for element-hq/synapse focusing on delivering business value through a major release cycle, stabilizing performance, and improving documentation and interoperability. Highlights include a comprehensive Synapse 1.139.0 release cycle with RC1/RC2/RC3 and final 1.139.0, expanding capabilities with experimental MSC4308 Thread Subscriptions and MSC4169 redaction sending, plus upgrade notes and changelog updates to simplify migrations for operators. Ongoing maintenance included Active sister releases (1.138.0 RC1 and 1.138.2 with Ubuntu release support updates). Technical hygiene improvements covered documentation cleanup (MSC4190 CHANGES categorization) and MSC2732 stability work (removing unstable prefixes from E2E/fallback keys) to align with final MSC2732. A performance-focused bug fix addressed the Delayed Events regression, restoring expected throughput and reducing latency under load. These efforts collectively improved release readiness, operator usability, and system stability, enabling faster adoption of new features and more predictable upgrades.

Jul 1, 2025Month 2025-07 summary: Delivered two Synapse release candidates with a focus on stability, performance, and developer experience. Release 1.134.0rc1 included a comprehensive changelog, feature enhancements, documentation improvements, deprecations, and internal build optimizations with dependency bumps. Release 1.135.0rc2 delivered a MAS user deactivation fix and a significant performance boost by caching server admin checks, alongside changelog/config updates, dependency bumps, and minor documentation tweaks. In addition, code quality and tooling improvements were completed via a trailing whitespace fix in build_rust.py and a cargo update to refresh dependencies. These efforts enhance deployment reliability, reduce runtime checks, and improve clarity and traceability of changes for stakeholders.
