OpenC3 COSMOS 6.1.0 - AnyCable and News

Welcome to OpenC3 COSMOS 6.1.0!

Potentially Breaking Changes

The change from ActionCable to AnyCable requires you to update your Docker compose.yaml file to add ANYCABLE_REDIS_URL, the openc3-redis/users.acl to add &__anycable__ and the openc3-traefik/traefik.yaml to add 2 new services: service-api-cable and service-script-cable. Please update your compose.yaml, users.acl, and traefik.yaml config files with the latest changes from cosmos-project.

Improvements

• Switched from Rails ActiveCable to AnyCable. AnyCable has much better performance and reliability than ActionCable and should help improve performance for all our websockets including the Streaming API.
• New News Feed in the User Menu which will primarily include information about releases
• Blur LED widget when telemetry goes stale
• Python instrumentation now supports try/except, can import future, and supports globals() and locals() in check_expression
• Created new Table APIs for creating binaries and reports
• Fully documented the Script APIs
• Created new ARRAYPLOT widget for graphing large static blocks of data (o-scope values) rather than individual telemetry points

Bug Fixes

• Fix graph layout grid in TlmGrapher
• FIx pip uninstall in the Admin packages
• Fix python UDP interface
• You can now create a WRITE_CONVERSION which converts a STRING to a UNIT. Read more at WRITE_CONVERSION.

Security

• Disallow parent dir path in sanitize_params
• Check file path prefixes
• Updated MinIO
• Patches for the following CVEs:
  • CVE-2025-28382
  • CVE-2025-28384
