May 2026 (chatwoot/chatwoot) delivered a focused set of security, reliability and performance improvements that strengthen business value while maintaining user experience. Key security work hardened the CI/CD pipeline to minimize exposure and improve incident visibility: GitHub workflow permissions are restricted to essential scopes, and a dedicated personal access token (GHSA_READ_TOKEN) was introduced for security advisories syncing to Linear with Discord alerts. Reliability and throughput were enhanced through targeted processing optimizations and robust error handling: per-email timeouts and retry logic for IMAP email processing prevent a single bad message from blocking the queue, and an early-return when no agents are online reduces Redis load during AutoAssignment. Private-network support for SafeFetch was added to enable trusted private calls in self-hosted deployments. Admin usability improvements were delivered by increasing the audit log page size to 25 records per page to reduce paging and API calls.
