• Removed docker subdir. Contents are now part of root.

0.7.1

• Add more CLI commands to pkg module
• Fix redundant YAML parsing
• Use lazy imports in CLI
• Add log output for device actor creation
• Exclude migrations from formatting
• Fix some linting issues
• Update dependencies

0.7.0

This is a major release that brings a host of new features and improvements:

• PostgreSQL is now used as the EOS database. Removed MongoDB.
• Re-implemented all data models to be relational.
• Implemented database transactions throughout the codebase to improve robustness.
• Implemented database migrations with alembic to evolve the database schema over time.
• Changed all tests to use in-memory SQLite.
• Added new CLI interface for managing the database, such as running database migrations.
• The REST API server is now fully integrated with the orchestrator process. Removed eos api.
• EOS now supports connecting to an existing Ray cluster instead of always creating a new one. This can help when debugging Ray.
• EOS now uses an adaptive spin rate. If there is no work, EOS will spin once every 2 seconds. If there is work, EOS will spin at 10 Hz. These rates are configurable.
• EOS now validates at runtime that correct devices are assigned to tasks when submitted.
• Experiments are now processed based on assigned priority instead of submission time. All tasks part of an experiment inherit the experiment's priority. Priority controls resource allocation order.
• Executors now incrementally process work. For example, they will now longer block while requesting resources, but instead submit a resource request and check in the next EOS spin.
• Improved some log messages.
• Implemented a DI container to pass around many dependencies in the codebase.
• Refactored and improved many parts of the codebase.
• Updated dependencies.

0.6.0

• Simplified several aspects of the YAML configuration syntax and reduced verbosity.
• Task and Device classes no longer require a suffix to be discovered and loaded.
• Removed Budibase.
• Removed dependency on omegaconf. All YAML loading and validation is now done with pydantic.
• Updated dependencies.
• Updated the documentation.
• Fixed bugs.
• Refactored and improved many parts of the code base.

0.5.0

Task and device methods are now asynchronous. For example, device initialization and cleanup is asynchronous. This allows implementing asynchronous device I/O, allowing for example to use libraries such as bleak for asynchronous Bluetooth communication with physical devices.

0.4.0

• Make most code async
• Make all db communication async
• Optimize db queries
• Parallelize db queries
• Change MongoDB integration to use a single-node replica set
• Integrate MongoDB transactions
• Refactor persistence code
• Add new tests and improve some existing ones
• Refactor and improve various parts of the code
• Update dependency versions

0.3.0

Initial public release.
