Added

• Tutorial for hybrid neural network using Covalent, AWSBatch, and Qiskit Runtime.
• Environment variable that users can set to specify the location where Covalent can find their defined executors.
• Task group id in Electrons.
• Reconstruct postprocessing method.
• Postprocessing as electrons.
• Postprocessing class in postprocessing.py module for all the different postprocessing helper methods and algorithms.
• disable_run option added to enable "saving-only" option on covalent server and not executing the workflow
• register_triggers, stop_triggers functions added to LocalDispatcher class
• triggers parameter to the lattice metadata
• BaseTrigger, DirTrigger, TimeTrigger classes added available to be assigned to any lattice enabling the triggers feature
• TriggerLoader class added enabling loading of any kind of triggers including user defined ones without requiring installation
• CLI options to start covalent server in triggers only, and no triggers mode
• is_pending option added during redispatch to resume execution of a previously "saved-only", i.e pending workflow
• API routes added for Triggers server
• Added feature to support cancelling workflow dispatches
• Updating/adding new tests to improve code coverage
• API endpoint for redispatching.
• Unit and functional tests for redispatching.
• TransportGraphOps class for diffing operations on transport graphs.
• Added make derived dispatch method.
• Apply electron updates method to _TransportGraph.
• Workflow re-dispatching functionality.
• Added dispatcher_addr argument to ct.get_result similar to ct.dispatch so that it doesn't always fallback to using the default configured address
• Front-end pending unit tests for the GUI.
• Adding support for PostgresQL DB backend
• Added check for COVALENT_DATABASE_URL, if exists connect sqlalchemy engine using that
• Adding COVALENT_DATABASE_USER and COVALENT_DATABASE_PASSWORD environment variables
• Adding COVALENT_DATABASE_HOSTNAME and COVALENT_DATABASE_PORT environment variables for easy configuration
• Added TaskRuntimeError exception for executor plugin implementations to signal to Covalent that a task raised an
  unhandled exception while running in the executor backend.
• Added environment variable for a remote database backend
• Added support for mysql and postgresql
• Support for transferring the contents of folders to and from S3 buckets using the file transfer module.
• RTD for User Interface
• Minor GUI fixes
• Ability to use terminal on the GUI.

Changed

• Postprocessing logic.
• Sublattice logic. Sublattices are now treated as electrons. Once the transport graph has been built, the status get changed to DISPATCHING at which point it is executed as another workflow.
• Modified ct.get_result to allow for status only requests
• Enhanced the Dockerfile to include builds from various sources and a differentiation between SDK and Server builds
• Location of function to load result from the database now moved to load module in covalent_dispatcher/_db folde.
• Changed decode-uri-component package version on webapp yarn-lock file.
• Changed json5 package version on webapp yarn-lock file.
• Reverted nightly frequency back to once a day
• Updated requirements.txt to include pyscopg2
• Refactored execution.py into loosely coupled modular pieces
• Updated directory like default environment variable paths to avoid creating redundant nested directories when self-hosting
• Docs for Covalent's Slurm plugin updated with explanation for optional srun parameters.
• Electron errors are segregated by type; task runtime errors are
  stored in stderr while the error attribute of a node is reserved
  for exceptions raised by Covalent itself.
• When tasks fail in a workflow, the Lattice ErrorCard in the UI summarizes the failed tasks.
• Width of lattice name column on dispatch list GUI.
• Optimzing larger graphs for better performance.
• Running migrations automatically if none have run in the past (fresh installs, after purging)
• Single line call to join instead of a for loop
• Updated black, mirrors-prettier, and detect-secrets in pre-commit hooks
• Made root_dispatch_id nullable to circumvent migration issues with sqlite in certain platforms

Removed

• Postprocessing from runners.
• References to specific IBMQ hub/group/project in tutorial 5
• Slurm executor reference from qaoa tutorial since it's not compatible with conda env at the moment.

Fixed

• Doubling of nodes that are added to the transport graph.
• Ensure postprocessing node end time is added as the workflow end time.
• Functional tests
• Custom executor how to guide, and its loading mechanism in covalent server.
• Broken postprocessing unit test.
• UI crashing if time values are null
• No longer adding "http://" every time a dispatcher address is provided in local dispatcher class in order to use the provided address exactly
• Redispatch bug involving copying reusable nodes from old transport graph to new transport graph.
• Pennylane tutorial notebook.
• Redispatch bug.
• Braket pip installation instructions.
• Removing the entrypoint for SDK-only install
• Updating client requirements to match server versions
• Load plugins only when COVALENT_PLUGIN_LOAD environment variable has been set to a Truthy value.
• MNIST tutorial now shows non-Null outputs and the classifier training log image has been updated.
• Minor changes to tutorials: autoencoder, quantum and classical svm, ensemble classification, iris classification with Pennylane, quantum chemistry, DNN tutorial, qaoa, spacetime tutorial etc.
• The range of networkx versions in requirements.txt weren't compatible with each other, thus it is pinned to 2.8.6 now
• SDK-only sdist and installation should now work as expected, not packaging the server
• Fixed naming of collection nodes (was breaking postprocessing)
• Restored compatibility with stable release of AWS executors
• Optimization of logs on the GUI for large log file sizes.
• Fixed UI pagination not working for more than 11 pages
• Runtime field counting down for select running dispatches
• Removed merge conflict symbols in changelog
• Build graph now sets all unset lattice constraints from defaults
• Fixed all failing functional tests
• Fixed local executor tests on MacOS by adding ProcessPoolExecutor
• Respecting specified AWS profile & region in remote executed S3 file transfers, defaulting to env vars of execution backend
• Electrons will inherit the lattice executors.
• Sublattices inherit the parent lattice executor.
• When several electrons are running concurrently, their stdout and stderr are stored in the correct graph nodes.
• Electron errors now appear in the Electron ErrorCard when one clicks on a failed task in the UI.
• When an electron raises an exception during execution, the local and dask executors now try to recover any output that was already
  written.
• Fixed functional tests.
• Added requirements-client.txt to MANIFEST file
• Respecting specified AWS profile & region in remote executed S3 file transfers, defaulting to env vars of execution backend
• Fixed local executor tests on MacOS (second attempt)
• The initialize_results_dir method attempts to use an environment variable instead of the results directory in the payload
• Modified certain sqlalchemy commands for postgres compatibility
• Removed references to results_dir in the payload
• Folder transfer unit test.
• Folder transfer download bug
• Result objects now print correctly when nodes fail
• Enabling logging by default
• Removed debugging output
• Clarify cli output when covalent db migrate needs to be run
• Rendering newlines in ErrorCard on the UI for displaying error stacktraces
• VERSION incrementing logic in changelog
• Fixed v11 migration to use render as batch to make DROP operations compatible with sqlite
• covalent restart honors the sdk.no_cluster setting
• Re-applying default executor fix post config file reunification
• Exceptions when instantiating executors are handled
• Covalent start now waits for the server to settle before returning

Tests

• Updated and added tests to account for all of the above triggers related changes
• Updated _get_result_from_dispatcher test ...
