OpenC3 COSMOS Core 7.0.0 Release Candidate 2 - Welcome to the future of COSMOS!

Welcome to OpenC3 COSMOS Core 7.0.0 Release Candidate 2!

We're super excited to announce the second release candidate of COSMOS 7.

Important
If updating from RC1 you should first do a "openc3.sh cleanup" as all the TSDB table names changed to now include the SCOPE. Note: Cleanup drops all logged data.

Key Changes since RC1:

  • TSDB Table Names now contain the SCOPE
  • New TEMPLATE_BASE64 Keyword
  • New Themes in Admin Settings!
  • Several bug fixes involving the TSDB, STRUCTURE keyword, python microservices, and XTCE

This release is months in the making and builds upon all the changes we made to COSMOS 6. Note that this is a Release Candidate and thus should not be used for Production deployments at the moment. We want to allow time for testing and exploration before we announce a final release.

The headline feature of COSMOS 7 is our new time series database (TSDB) powered by QuestDB! This database allows us to speed up our data retrieval times by an order of magnitude and enables optimizations like the removal of the reducer microservices and associated data. This is going to enable a host of new integrations and use-cases. I invite you to enable the QuestDB console and experiment with SQL access to your data!

We've also changed our License from the AGPL to the new COSMOS Builder's License. This gives you the same rights but is more compatible with our new App Store. It explicitly does not allow providing COSMOS as a hosted or managed service.

Breaking Changes

  • Migration from MINIO to versitygw as a S3 backend. See upgrading.md for more information.
  • Removed plaintext password support for API. See upgrading.md for more information.

New Behavior

  • Remove WITH_UNITS as type. Note that existing with_units APIs (tlm_with_units, check_with_units, etc) are deprecated and will simply return the formatted value.
  • get_target_file now returns None/nil when file is not found
  • Return nil/None for items outside buffer bounds in undersized packets. Previously this would return 0. This allows for sparsely populated packets.

Known Issues

The migration script is currently hard coded to use the logs and config bucket names. If you have renamed these using the .env file OPENC3_LOGS_BUCKET or OPENC3_CONFIG_BUCKET this will not take effect. This will be fixed in the final release.

Enhancements

  • UI theming support - check the Admin Settings to change COSMOS colors
  • New TEMPLATE_BASE64 keyword for binary templates in the config files
  • Queue interface packets by default with update at 0.1s
  • Add hover tooltip, context menu, and stale overlay to LIMITSCOLOR widget
  • App store API updates
  • Optimize command and telemetry decom performance in Ruby and Python
  • Add hint to admin console about setting k8s secrets
  • New API for scripts and screens to open a browser tab
  • Make Command Parameter list scrollable for Command Editor
  • Validate SCREEN params and make options dialogs consistent throughout
  • Bucket Explorer delete directory
  • Telemetry Grapher select graph button
  • Migrate Python package from Poetry to UV
  • Workflow to restart microservices for a plugin
  • Warn when packets are defined without ID_ITEMs
  • Add UUID to Script Runner temp files to prevent name collision
  • Update to Vite 7
  • Update to Rails 8
  • Switch from Redis to Valkey
  • Switch from Vuex to Pinia
  • Switch password hashing algorithm to argon2

Bug Fixes

  • Fix xtce_converter CLI crash
  • Fixes for STRUCTURE use
