June 2026 (2026-06) monthly summary for waterloo-rocketry/omnibus: Delivered a robust CI/CD infrastructure and deployment pipeline, including Docker build workflows, issue templates, and repository documentation; standardized development environments and introduced a launcher utility and data-stream dashboard. Fixed Docker container import path issues by switching to unscoped imports in bridge and websocket_server; updated LJM DAQ messaging to v3 for omnibus-ts compatibility, converting relative timestamps from nanoseconds to seconds. Resolved CI GitHub Actions cache isolation to prevent multi-image build cache corruption. Upgraded production WebSocket deployment to Gunicorn + Gevent, refactored relay sender for non-blocking operation, and expanded test coverage for lifecycle and concurrency. These efforts collectively improve deployment velocity, runtime reliability, data integrity, and developer experience.

April 2026 — waterloo-rocketry/omnibus: Delivered Websocket service enhancements and Docker deployment support. Key changes include aligning the websocket message format with TypeScript by using tuples for multi-argument messages, standardizing timestamp naming by renaming relative_timestamps_seconds to relative_timestamps, and adding Docker deployment support with Dockerfiles for the websocket_server and bridge plus an updated Docker Compose. Tests were updated to reflect the new tuple-based messaging and separate timestamp/payload arguments, improving reliability and maintainability.

March 2026 monthly summary for waterloo-rocketry/omnibus: Implemented a Docker image size reduction via a multi-stage Dockerfile to optimize deployment footprint and startup times. The runtime image now uses a lightweight Alpine stage to download and extract the LJM installer, then binds it into the final image while removing unnecessary tools and artifacts. Added apt cache mounts and --no-install-recommends to minimize image size and improve caching. This change enhances CI efficiency, reduces resource usage in production, and strengthens security by shrinking the attack surface. Commit 9f4800c3a47664671598ef4df64ed574d11f2937; Closes waterloo-rocketry/2025-software-issues#110.
