Version 1.18.0

Release Date: August 20, 2026 Release Type: Stable

System log monitoring suite — configurable server-side log retention and format, a system log viewer in Monitoring, and the new System Logs and System Log Settings pages — plus internal groundwork for upcoming observability features.

Backend Server​

New Features​

  • Groundwork for richer logging and metrics: Internal preparation for upcoming observability improvements — a catalogued message-code system and a standardized flow-metrics vocabulary — was added behind disabled feature gates. No behavior changes in this release.

Bug Fixes​

  • System log retention is now configurable: Server system logs were previously kept for only about one day and then lost. Log retention, location and rolling behavior are now configurable via settings, and the log line format was made cleanly parsable.
  • All Steps logging now records attachments on every node: With logging set to All Steps (Full Log), multipart attachments received at the Start connector were only visible on the entry log, not on the per-node logs of later steps such as HTTP calls or Set Context. Every step logged under All Steps now saves the message's attachments as well, without affecting flows using payload-only logging.

Frontend Server​

New Features​

  • View system logs directly in Monitoring: System logs can now be viewed in the Monitoring UI without downloading log files, with filtering and sorting like Message Monitoring. Retained logs older than one day (rotated files) are now readable with reliable cursor-based paging, and the new system log endpoints are restricted to administrators.
  • Internal groundwork for observability: Internal scaffolding for standardized log/message codes and service-to-service communication was added, including support for rendering response timestamps in the caller's time zone via a Time-Zone request header. No workflow changes are required.

Frontend Web​

New Features​

  • System log browsing with retention settings: The System Logs page now lets you browse the full retained log window — including entries older than one day — with log-level and multi-select service filters and reliable cursor-based paging. A new admin-only System Log Settings page presents each service's retention and log-level settings in a clear table layout.
  • Internal groundwork for improved observability: Behind-the-scenes scaffolding for standardized API responses, error references, and request tracing was added in this release. It has no user-facing effect yet and prepares upcoming observability features.

Health Check​

New Features​

  • Internal groundwork for standardized service APIs: Internal-only scaffolding was added for a future standardized API response format, per-request time-zone handling, and a complete service endpoint catalog. It is inactive by default and has no visible effect in this release.
